Everytime I need a refresher on backwashing my DE filter this video pops up on UA-cam. Wish you lived in Texas I would be calling you out. :) Thanks so much for the explanation and details. This video is the best.
Glad to be of help. Thank you for your kind remarks.
This was the best video I was able to
Watch this and pause step by step while backwashing . Normally I need my husband . Thank you soo much
So glad it was helpful. Thanks for watching and commenting. I hope you’ll subscribe to my channel and share it with everyone you know who owns a pool.
This was by far the most concise, well explained video I’ve come across on backwashing a DE filter. Thank you. This is my first filter without the main valve on top where you can turn it from filter to backwash or rinse etc. so I was clueless as to how to backwash the pool in our new house so thanks again. Also, did some digging and found that 4 pounds of DE is 24 cups or 6 cups equals one pound.
I'm delighted to hear this video was helpful. Hope you'll subscribe to my channel.
Outstanding easy to understand video. Thank you very much Kenny. You are the man !!
This is my go-to video when it's time to backwash my DE filter. Highly recommend this channel to anyone looking to maintain their own swimming pool. Very clear and concise...
Thank you, glad it was helpful. Hope you’ll subscribe to my channel and share it with all your friends.
New pool owner here, I’ve been trying to do the pool maintenance on my own since we got it and I want to say this 1000 times, thank you sooooo much! I was tempted to hire someone to do this for me but this was all I needed
RAAM Visuals I’m so glad my videos have been helpful.
Another way of adding DE is to put the DE into a 5gal bucket, slowly add water (minimizes kicking up the DE into the air) then mix the DE really well in the bucket until it’s all suspended (floating) in the water. Then you can pour it into the skimmer. I was told that this method allows the DE to more evenly get distributed across all of the grids in the filter. Great video!
That was actually the way the guy I bought my first house from told me to do it back in 1983.
This is the way I do it. I use a small hose from the bucket to the skimmer, being disabled, so I can let the D.E. bucket water to be fed a little at a time. I used to sprinkle the DE water into skimmer very slowly holding the bucket. I noticed at one point some of the DE bucket water going back into the pool. So now I just prime the little hose by sticking the end into the skimmer hole with my hand wrapped around it. There's my prime, now the bucket water is going in as much as I want without back washing into the pool. For every one pound of DE I use 5 gallons of water. I think this may help coat the filter more evenly. It used to ask be at the bottom of the filter pump. Not anymore. Have an awesome day all! God Bless! ❤
We live deep in Baja Mexico well off the grid. Your tutorials are invaluable to one who does all his own pool maintenance. I never knew about flushing three times! Makes total sense. So I just went out and did it since the water truck is coming tomorrow to fill up our tank under the garage. Lots of issues to consider here with very hard water, all solar power, no availability of liquid chemicals etc., but somehow we manage! Thanks so much for sharing your valuable knowledge.

Thanks Kenny for the Pool School videos!! I'm a new pool owner and a proud pool girl, keeper of our pool. I really needed the help!!
Leah Farber glad to be of help.
I just want to add to my previous comment a massive thanks. I had to take over our pool maintenance two years ago and had some issues. It was ok but never great. This past Friday our pool was so bad I couldn't see the deep end. I had issues with the pump and pressure and suction. I was determined to fix it and watched a lot of videos, then attacked it full force on Saturday. Your videos were by far the most helpful and explained everything thoroughly. I literally started from cleaning the filters and using a bladder to clear the lines. It's now 7pm on Monday night and I'm at Lowe's to get chlorine tablets to maintain the crystal clear pool I was able to achieve in 48 hours. And for the first time I've learned how to get my automatic vac and skimmer to work at the same freaking time. Can't thank you enough!
Kathy O I am so happy to hear this. Congratulations on your success with your pool. And thank you for your kind comment.
Wow. Must be a "Kathy" issue! LOL I had the exact same experience. I have not reached the success level yet, but totally agree. The videos are great! On my way to backwash! Thanks for the great videos Pool School.

Thank you for this great tutorial! I've been backwashing my DE filter incorrectly for approx 15 years. I didn't realize I've been running the backwash cycle way too long. It explains why my grids haven't been holding up for more than 2 or 3 years.

Hi Scott, thanks for your kind comments. I appreciate it.
@Joe Kinchicken I'm totally with you.
@@PoolSchooler Hi Pool School and Joe Kinchicken.
Serious question regarding your hesitation with DE vs Cartridge. I had an above ground pool many years ago as kid (35 years ago)with a Hayward DE filter. Water always seemed very clear but I didn't have any reference to compare to. Now I'm looking at a pool for my family and retailer offered my choice of sand, cartridge or DE, with no price difference.
She stated that sand can last 5 to 7 seasons. A clarifier can be added to clump small particles and allow sand filter to trap them. It requires the least maintenance. It filters down to 20 to 40 microns
She stated that cartridges usually last 1 season and there is some effort to remove top to flush and clean cartridge. A clarifier can be added to clump small particles and allow cartridge to trap them, like you would with the sand filter. It requires a medium amount of maintenance where you remove the top, and just spray it off with a hose. It also uses the least amount of water, as it doesn't require backflushing like sand or DE. It filters down to 10 - 15 microns
Simialr to the above two, a DE filter need maintenance when pressure increases indicating resistance. Bumping process with handle seems simple to me and I don't recall her stating how long the DE lasts but got some insight from this video. There was no need for clarifier as the filter is supposed to go down to 5 microns and possibly as low as 2 microns. It requires the highest amount of maintenance and I got a refresh of this watching this video.
Water is very inexpensive where I live (my town borders on one of the Great Lakes) and she mentioned that DE pump uses the least amount of power to achieve the same water clarity.
If I have no hesitation with bumping and backflushing and the technical aptitude to do it, would you still recommend the cartridge vs DE and if so, why?
@@tedk9144 I think in your case it's just a matter of personal preference. When you talk about measures of particles in microns it's actually getting down to splitting hairs in my opinion. All three have advantages and disadvantages, in my experience I have found the cartridge filters to be the ones I prefer over the sand and DE. But really if you like the DE filter then that's fine. It's your pool and your choice and you seem to have done your homework and made an informed decision for what you want.
Thanks Kenny for making this video friendly for all of us, well done.

Great video got my pool to have full suction back again!!!! Thank you so much!!!!
Awesome! Way to go!!!
Great channel you have PS, you're a natural teacher. And as a ten-year owner of a Hayward EC-65 DE filter, I agree with everything you describe (although my procedure for recharging is somewhat different).
(Sorry for the length of this!)
A couple points I'd like to add: The DE itself is a naturally occurring product (from sea plankton, iirc) so if you dispose of it in the yard, or it's leaking back in the pool, it's non-toxic and harmless. I've been dumping mine out into a side yard for years and all it takes is one rainstorm and it's gone into the soil and the yard shows no signs of damage or stress. But because of the physical nature of it, you're right not to rub it if it gets in your eyes, nor should you inhale it.
You're clearly working in a warm climate where pools don't really shut down the way they do here in the NE US. One thing I struggle with (maybe the only pool-related thing I struggle with), is opening the pool in the spring, when the water has turned a dark brown with all manner of debris and algae. In the first 2 weeks or so, depending on how much free time I have to babysit it, I might recharge the filter 7-8 times at 6-7 pounds of DE each recharge. That's insane and every year I promise to find myself a cheap used cartridge filter I can set up just for the initial cleanings. Alas, I never do. Would love to hear other ideas for getting over this initial yearly hump.
Some wonder about whether the trouble of these filters makes it worth it. No other medium filters the water the way DE does. The clarity you get is stunning. Underwater with a mask in my pool and it's easy to imagine there's no water at all.
FINALLY, the most important message I've seen in the videos of yours so far that needs to be amplified to 11 is your last one about children. In my (much) younger years I was a lifeguard, at some pretty high profile and pretty busy places. I made lots of rescues and a significant number of them were children, and the speed that a kid can get into trouble in the water will send chills up your spine. I've rescued kids whose parents were standing within 7-8 feet from them but distracted by chat with others, in water that wasn't 2 feet deep.
Kids need first to be water-proofed. I came through the Red Cross programs and think very highly of them. Then as care-givers or parents you just cannot take your eyes off them for more than a couple seconds, SERIOUSLY! Thank you for including this message, it cannot be overstated.

Thanks! Your video helps me backwash my pool! Many thanks!
Glad to be of help. Hope you'll subscribe to and share my channel. Exciting announcement coming early spring 2021.
So easy to understand your videos! Thanks for helping all of us with our pools! No one ever told me I should backwash, let alone I didn't know it existed! Lol. Hopefully this will help me with upkeep on my pool. This weather in Florida has knocked everything out of whack. This is the first month being July 2023 that I've had severe rapid growth of algae was almost overnight. Crazy. Hopefully I can get this thing back to normal soon. Temps are running around 96° with a feels like temp around 115° these past few weeks and then there's the rain everyday. I just want to be able to get into the pool at some point this summer. I have a DE pool.
I did a video on Algae and Algaecides and Why You Don't Need Them and I think it'll inform you greatly on the algae issue. Here's a link: ua-cam.com/video/MzGoK4Cd7tc/v-deo.html Also since you have a DE filter the grids can sometime tear and dump DE into your pool. This video will help you understand that: ua-cam.com/video/Khkr02ZTqlI/v-deo.html

Great video, simple explanation. Noticed at 4:36 the filter label indicates how much DE to add, so no need to calculate.
In this case the label does give guidance but many times the label has worn off or peeled off

Hello,
Great Channel
I'm a new pool owner we have a 16 by 32 ft. Inground 2 ft to 10 ft.
I have a 36 sq. foot DE Cartridge filter. (Hayward)
We bought a Foreclosed On Home.
Pool was abandoned for 2 years I skimmed out 450lbs to 600lbs of Black/brown soot. Yes 450/650 LBS. Water was Black. From I guess decayed leaves.
Following minimal soot in skimming net. I shocked water with 5lbs of shock a day.
Ran filter 5 days 24 hrs. Back washing 3 times in between total filter cleaning.
Water is now crystal clear.
But filter pressure is rising to 20 to 25 lbs. psi after 4 to 6 hrs run time.
Following 3 to 4 back washings pressure is shooting up to 25lbs psi within 1 hr of filtering.
I soaked grids in Muriatic Acid (by the way grids are new). I thought perhaps from water being so black they were compromised.
No Improvement
???
Is it normal for DE filter pressure to rise in such a short period of time. Even though water is so clean and clear.
After cleaning filter I put in 6lbs of DE.
Manual recommends 6 lbs. DE bag directions say 7 lbs for a 36 sq. foot filter.
Total Chlorine 4 ppm
Free Chlorine 3 ppm
PH 7.4
Alk. 100
Hardness 250
!! CYNARIC ACID "0" ???
What do you think?
Just friendly advice I realize to difficult to diagnose with certainty without first hand inspection.
Your educated guess is better then my No Clue kbowledge....
Thank You

Sounds like you really worked a lot to get your pool clean and clear. Usually I'd say that you may have a torn grid or manifold but that doesn't seem to be the case here.
Is it possible you're adding too much DE? For that size filter I'd suggest no more than 4 lbs of de when you recharge.
Or (and I'd really consider this one), your grids (even tho they are new they had to do so much work filtering out all that gunk they may be super dirty and you may need to clean them).
I'm not sure why you used muriatic acid but you said they were compromised, so I'm thinking you problem may be that your grids, albeit new, are shot because of all the gunk AND using muriatic acid to clean them, you may have compromised the fabric so much that they are not permeable enough and thus create too much pressure. You may have to replace them again (sorry to say). In the future you should only need to use a regular hose nozzle to clean the grids. I really believe the grid fabric was made less permeable by the acid and all the gunk. Try replacing them and see what happens.,
Also, it's possible something went awry when the new grids were installed and everything put back together.
You may want to make sure your return flow valves are open fully so as to allow unhindered flow from the filter back to the pool.
Lastly, its possible that with all the gunk your filter had to filter you may have a clogged line somewhere in the return from the filter to the pool that may be causing it.
That's about all I can think of. Let me know what you discover. OH, and my thought about what you originally had to deal with
Thanks a lot 🎉

Thank you. 👍👍
Kenny hi - great video thanks! Very clear. Thanks. I have some bubbles coming out of my return lines to pool and spa. I have had two pool guys round to check as I also have a small amount of water coming out near my spa steps. We have done step tests, isolation test etc and got it down to the return lines. They say it's a small leak and advise using ' fix a leak' through the skimmer. It's a below ground pool so wondering whether it's best to dig up to get to the pipes or use 'fix a leak' solution. Any advice please?
Jackie Montado I would suggest fixing it right by digging up that area and fixing the pipe. It’ll be better in the long run. And I think it’s worth the cost. Some places it totally ok to save $$$ but some things are worth the cost of fixing right. This would be one of them.
Thanks for the great video. I have a variable speed pump. What speed or flow rate do you recommend for backwashing.
I would recommend high-speed at least 3500 to 3800 rpm. Typically you’d want it around the same speed that it turns to keep the suction side vacuum going if you have one.
Thank you
One of the best tutorial videos about backwashing I have seen! One question: When recharging is it better to mix the DE powder with water prior to adding to the skimmer? I've heard that this method coats the grids more evenly. Thanks.
Hi Dan. I'm glad you liked the video and that it was helpful. Regarding your question. Back in the 80's I was taught by the guy I bought my first house from in Southern California to mix the DE with water before adding it to the skimmer. However since I started servicing pools professionally (starting in 1994) all the guy I worked for never had me mix it with water. Just pour it directly into the skimmer WHILE THE PUMP MOTOR WAS RUNNING. I've been doing it that way ever since and have had no problem with it not coating the grids good enough. So all that to say, you should just be able to put the DE directly into the skimmer (take the basket out first-makes it go down better) with the pump motor running.
Hi, I am a retired pool professional of over 30 years. And technically yes the instructions do say mix with water, but very few people do that. I would agree with everything in this video except I always kept the basket in the skimmer while adding D.E. because it helps break up any clumping that might occur.
Yeah always keep the basket in while adding the DE!!! Your no pro sorry. And by the way I don't recommend breathing the DE in, its never good to introduce foreign materials to your body, but just for your viewers info, DE is simply crushed up sea shells, lots of calcium and small amounts of other minerals but not toxic to us in small amounts. Always add chemicals upstream of the wind when possible and for a side note it's a very good non toxic safe for children and animals pesticide. Cheap as hell and works great to smother all insects. Look up how insects take on oxygen and it will explain.!!
@@soulfulelf3821 while you might be a self professed god of all things pool related, to insult the creator of this video by not insinuating ‘he’s no pro’ is pretty disrespectful. Everyone learns differently and had different teachers. Personally I thought this video was excellent and perfect for his target demographic.
One wonders why you even watched the video given you apparently know it all.
@@soulfulelf3821 take a step back and realize that you are gatekeeping for pool maintenance. The basket doesn’t matter at the end of the dang day. You come across as the dale gribble of pool maintenance with a good amount of pocket sand on hand. Is it better to wipe standing up or sitting down?
THANK YOU SIR
You're welcome
Some pools have DE filters that are gravity fed from the skimmers or gutters and the pump pumps the clean water out of the filter and back into the pool. Also, the filter is open on top so the DE is added right to the filter.
Good to know. Thanks for commenting.
I work at the processing plant that produces that DE filter media its actually kinda cool to see where it goes and how its used but word of caution try and use a good respirator we use them at all times due to the risk of scoliosis from the silica present in the DE
Oh wow! Frankie, thanks for that bit of information. I was not aware of that risk. Thankfully I only have two clients who have DE filters but I will for sure start wearing one. Yet another reason to not have a DE filter. Good information, thanks for commenting.
*silicosis 😂 scaring of the lungs.
Had me really curious about how DE could cause curvature of the spine 🤓🤔🧐🥸🥰
I just backed washed for the first time, it seemed pretty easy ! I hope I did everything correct, lol. Thank you you are a great help I believe I’ve learned everything from you . One question, what happens if you go over DE by like a pound ?
Outdoor Stuff Glad the video was helpful. If you go over on the DE buy a pound or so it’s really not that big a deal but sometimes it can restrict the water flow a little bit more which can in time create more stress on the fabric of the grids. Or might mean you’ll have to backwash it sooner.
Enjoyed your video, did not know about the 3 times of backwashing. My backwash system is not completely shuting off. What can I do about this
Sada Twinkletoes sounds like you need to replace the o’rings in the backwash valve.
so every time I backflush i should put more dE in? I have not been doing that. I have just been doing a quick backflush but if i do it three times i will need to really put in DE.
You should always do it three times so you get rid of as much old DE as possible. then you absolutely should recharge it.
Thank you for posting this video, very helpful. What would you do if you don’t have a backwash valve?
Shadi Bader if you have a DE filter it has to have a backwash valve. Only cartridge filters don’t have a backwash valve. Please watch my video on types of filters.
Shadi Bader watch this video to see what type of filter you have. ua-cam.com/video/ixUlq_obtiM/v-deo.html
@Pool School I have a Waterway Plastics - CLEARWATER DE FILTER 90 - FD090. I absolutely have seen no backwash valve.
Thank you for this super helpful video!! Question: is the amount of DE added after backwashing different than the amount to add after fully washing the grids? Thanks!
Hi Jessica, no it’s the same.
Great tutorial. I have an issue with my d.e filter. I constantly have to do a back wash to maintain a good suction preassure. The good operating pressure is 8 psi and when my pressure hits 20 psi I get no suction. Now Thats when i do the backwash to get good pressure again.Crazy as it sound Ive been doing it all weekend. FYI, NO leaks on the grids .Installed new grids. Any suggestions?
24 gearhead you might have to have the grids cleaned. Sounds like a lot of d e is imbedded in the grids. I usually have my clients grids cleaned once a year and that’s with regular backwashing.
I have learned so much from your videos, thanks! So my normal pressure was 20. Then it went to 30, and my skimmer lost suction. I did the backwash and it went back to 20 and my skimmer suction increased. Then a day later my pressure stayed at 20 but the skimmer has lost most of the suction. Any ideas why? Thanks
Very possible you have a torn grid or more. Check out this video and see if it helps: ua-cam.com/video/Khkr02ZTqlI/v-deo.html keep me posted.
Is locking the valves necessary? Mines a little jammed and old so its hard to lock but it works very well pulling and pushing.
Locking can be important, I've known valves to pop up under pressure. If it's sticky it probably needs lubricating and possibly new o'rings. Here's a link to a video I did on that: ua-cam.com/video/qdHijgpuiS8/v-deo.html
It should help.
First, thank you so much for video help!! I’m still new to doing myself. Couple questions please. I tried looking through comments first.
I mix DE with water before adding to skimmer. I pour directly into skimmer while PUMP MOTOR is RUNNING BUT* should the dial be on main filter, skmmer or set in middle 50/50? Hope not a stupid question, still learning. I also noticed n skimmer area on floor, under basket. 2 openings. One has a slide cover over it. Should that slide lid be open or closed? Again, hope not stupid question just trying to learn all.
I noticed some of the DE flowing back into pool water so want to make sure pump dial (skimmer or main drain is set right). Have pop up pool cleaner, one of pop ups keep coming out. Doesn’t seem to clean well? Lot of sandy/crumbs on floor of pool. Recently had a tech rebuild/replace that floor cleaner valve part (5 port?) He removed small/ tiny filter in that area , says keeps getting clogged. He seemed to be well versed on rebuild but had to do again due to faulty part
Pool Needs a refinish but can’t afford right now. Thank you!! I will share your page and recommend to others. Daryla Your video is great!
Hi Daryl. Could you please copy and email your questions to me? My email is kennypoolschool@gmail.com. And if you could let me know if your have a pop up in floor cleaning system or not AND possibly send a picture of the two holes you have in your skimmer sump. Also if you do have a in floor pop up cleaning system does it have a dedicated pump that's separate from the filter pump? These will all help me more accurately answer your questions. Thanks so much.
My apologies Daryl. I didn't read your comment fully. So here's my thoughts:
1. You don't need to mix the DE with the water before adding it to the skimmer. I too was taught to do this and after working for several pool service companies I learned you didn't need to mix the DE with water first. Just MAKE SURE YOUR MAIN FILTER PUMP IS RUNNING when you add the DE directly to the skimmer (may be a good idea to remove the skimmer basket when you do.
2. The two openings you talk about are usually one that is the suction from your skimmer to the filter pump. The other one usually is for the floor drain. The slide cover, is not something I"m familiar with, but usually the second opening (hole) goes to the floor drain and there is usually a "diverter" (see this link for a pic of what I'm talking about: images.app.goo.gl/Tr4Ag16g2TXXpoeJ9). It can be adjusted to "divert" some of the suction from the skimmer to the floor drain to help suck out debris with a pop up system. My best guess is the flap on one of the openings is to help do the same thing. It's pretty easy to determine which opening is sucking from the main pump to the filter as it'll have all the suction.
3. You said that you noticed DE flowing back into the pool and that you have a in floor pop up cleaning system. Have you noticed the DE flowing back through the pop up heads? Do you have a separate pump/motor that provides pressure for the pop ups (separate from the main filter pump/motor)? If so what's happening is if you are running both the filter motor and the pop up system motor when you add DE, some of the DE is getting sucked into the pop up motor, and. since there is no filter on that "side" of your system the DE is blowing back into the pool. DON'T RUN THE POP UP MOTOR while adding the DE to you skimmer. ONLY RUN THE FILTER MOTOR. That should stop the DE from blowing back into the pool since ALL of it will now be going where it belongs, into the filter grids.
4. I did a series on pop up systems and replacing a pop up head. What you're describing is a pop up head that's "teeth" or. tabs that hold the head in place are either worn or cracked and the moment it gets under pressure it pops completely out. You'll need to replace that head. Here's a link to my video on doing that: ua-cam.com/video/To3hieR036E/v-deo.html. The filter screen you describe is notorious for getting clogged up. Another reason I'm not a fan of pop up systems. Most of the newer pop up systems don't have that screen filter anymore. You mentioned a lot of "sandy crumbs" on the floor of your pool. This is not uncommon with pop up cleaning systems. There are lots of reasons for this. But you may just want to watch my videos on pop up systems. Here's links to them. I think they'll help inform you:In floor Pop Up Cleaning Systems: ua-cam.com/video/m6h7Lh76Vvg/v-deo.html
I think I've answered all your questions. Hope its been helpful.
I am about to do my first backwash, and I have a scooper that LOOKS like yours (blue with curved bottom, but mine is new and still has a handle), but I want to be sure it is the same size. On the inside of mine it says 770g and 24oz to the top but I know DE doesn't seem as dense so the DE weight isn't the same as a liquid measure. Do you think this is the correct scoop?
Hard for me to tell without actually seeing. If its close to a pound per scoop you should be fine.
Is that the name of a band ?
Just kidding.
Thank you for the information
Awesome brother
😉😂.👍. Thank you sir.
When i first open my pool for the season, I may have to backwash 5-10 times a day for the first couple of days. Do I still put in the recommended dose, 3 lbs, each and every time? Isn’t that too much DE since it all doesn’t backwash out?
The purpose of the filter is to filter out small particles so you need adequate, clean amounts of filter media to do that every time you’re in the filter. So if you backwash your filter, the way I describe in this video you should recharge it fully so that it can do its job and clear up your pool. If not, you’re going to hinder the effectiveness of the filter itself. Unfortunately, that’s one of the drawbacks to having a DE filter. And if you seen my video on DE filters and why you shouldn’t have one you’ll know other reasons why I don’t care for them. I’m sure in your situation. A cartridge filter is not the most desirable one to have, but there is a product on the market that replaces sand in a sand filter with glass. It’s called Dr. Dryden‘s glass filter, Media substitute it’s more expensive than sand, but it’s guaranteed for the life of the filter, you never have to change it and it filters as good as DE without the safety hazard or mess. the studies that I’ve seen it say that it filters particles as small as 3 microns which is the same as DE.
You might want to look into that for the future and get away from using DE altogether I personally think it’s a much better option again to clarify a sand filter using Dr. Dryden‘s activate glass filter, Media substitute instead of sand
I changed the grid the screen the selector valve on my Pentair still getting white powder at the bottom of pool. Any ideas?18*36
Not sure, I know somebody else had that problem there might be a crack in the manifold.
The water bill where I live is very high.
IME - I just clean the filter. Imo, its the most efficient and effective.
Awesome vid! Professional preference question: would you recommend a backwash hose? Or buy an adapter and use the vaccuum hose?
John Zavala it really depends on where the backwashed water goes. I have a couple that are actually hard plumbed into the sewer system. That always has to be done to code and based on county guidelines. I also have one that they hard plumbed PVC pipe to a drainfield of sorts. But most of them we just use a backwash hose.
@@PoolSchooler the water would go to the yard either with either option. But i was researching online to find one and a lot of reviews say theirs exploded or had pinholes. So i was just thinking i could use the same hose that the Barracuda uses.
John Zavala I guess you could, but because those are sectional they might come apart too. Also those are meant to be in the pool 24/7 so they might dry out and crack pretty easy. I know the backwash hoses do get pinholes in them, but they’re not that expensive and should last you at least a year.
So I have a pentair filter and it was reading 30PSI where the gauge says Clean Filter. I cleaned the filters inside the tank, hosed them down got all the debris, dirt and DE clinging to the filters off. Once i did that i then put the new DE through my filter but my gauge still reads 30PSI and clean filter. What did I do wrong or is there something else I need to do??
Appreciate the videos, they have been a huge help. Thanks
Nick Nolan is start by making sure your return flow back to the pool isn’t restricted in any way like maybe a valve being shut a bit. If all valves are open it may have to do with your manifold inside the filter. If it’s broken or clogged in anyway that could do it or the remote possibility of it being reassembled incorrectly could effect it too.
For my pool. I was trying to use the skimmer as a vacuum and it will not suction. I'm trying to find out which valve I close and leave open to know where I can put my hose for the most suction power. Another thing is that yesterday I started getting debris back into my pool coming from the water jets that pump water back in. Turns out I had put the filter in wrong and went back and adjusted it. Should I keep running the pool and it will eventually filter out all the debris? Thanks.
This video may help: ua-cam.com/video/nJCg8SjdBCM/v-deo.html.
Regarding the debris blowback. If you have a cleaning system (pool vac or pop up cleaning system) it should get it. If not you may have to manually vacuum it or net it out.
Here's a link on how to vacuum your pool "the old fashioned way": ua-cam.com/video/x9WaMUzSO-8/v-deo.html
Hope these help.
Do you still need to use your little pool genie or a pool robot to go along the bottom of the pool to clean? Or is this pool cleaning filter going to keep your pool clean enough that you don't have to worry about that?
It’s important to understand the difference. A pool filter filters out dirt particles that are in the water. The vacuum is what sucks that dirt into the filter so it can be filtered. So you do need a vacuum and I would suggest the barracuda G3. It is a section side to stay in the pool vacuum and it is absolutely my favorite vacuum 98% of all my clients have one and it works great
Well this explains why my pool is cloudy and I can’t get rid of it. New grinds installed soon
Glad to be of help.
Great lesson, thank you so much. I just wonder what would happen if maintain the filter with proper backwash BUT w/out putting in DE in the filer? Would it be still ok or just not as clean?
Jason lim if you have a DE filter you most definitely want to recharge it with DE after backwashing it. If not you run the risk of severely damaging the grids. The explanation why is a bit lengthy so I won’t go into it here, but suffice it to say that you most certainly want to use DE to recharge your filter after backwashing it if it is a DE filter. They are not meant to work without the DE.
We have no non-windy days in Texas...
How do you change a light that's out in the jacuzzi or pool?
So when it comes to doing either of these things I'd recommend spending the money to have a pro do this. Water and electricity can make a deadly combination. And although it's fairly easy to do I think this is one of those things best left to a pro for safety reasons. If you don't get the power off correctly or you don't get the seal for the light just right it can lead to electric shock which is not good. This is why I haven't done a video on it.
For the past several months my filter pressures never exceeds 10 psi. It used to raise to around 25 when dirty. I’ve replaced the pressure gauge and all
The pool doesn’t seem to have any issues. Pumps good and water clarity and chemicals are good. Any ideas? .
Do you have adequate suction and return flow? If you have the proper amount of DE in your filter (after backwashing and recharging) and the pressure's still really low (typically after backwashing and recharging your psi reads somewhere between 12 and 18 psi) perhaps you have something restriction the suction side of your pool. I'd start by checking the pump impeller to make sure it's not clogged. Watch this video ua-cam.com/video/1xuGFGDJBmA/v-deo.html
is that handle you pulled up for the back wash ever located on top of the filter
It can be, I haven't seen any like that on DE filters. Usually the ones with the backwash valve on top are sand filters
I clean my filter & added de, but I had to open the filter lid a couple times cuz it was leaking around the clamp. Do I need to add more de if I all I did is take the lid off & put back on? Need answer ASAP please & thank yoy
Ok, so to confirm, you took your DE filter apart to clean the grids and after putting it back together it leaked at the belly band? If that's what's happening you need to fix that leak. It may be that yo didn't tighten the band enough or for whatever reason it's not sealing (a bad o'ring or maybe just the rim is dirty or has debris). NO don't add any more DE until you stop that leak.
Hrm, my filter has no valve of any type, it does have a handle on the top sticking out to one side. It's a Hayward brand, says EC-75, it's a very small filter compared to the one you're showing here. How do I backwash this thing? Do I have to take all the bolts out every time I backwash?
Typically the EC-75 is a DE filter. Unfortunately I don't have any clients who have a filter like that but if you do a UA-cam search on how to backwash an EC 75 (or 65) filter you should find something that will help you.
Thank you for walking me through the process!
You're welcome. Thanks for watching and commenting.
I don't get it I completely cleaned out my filter, but the PSI gauge is still showing psi readings between 20-30 without DE what gives? Also, my pump seems to be working fine and is not taking in air at all so the rise in psi can't be due to air intake from the suction side, I have a Hayward EC75A Perflex and a Hayward 1.2 HP pump.
You may want to check your return flow valves and make sure they are fully open. Closing off any return valves can increase your filter pressure.
I watch a lot of pool care videos and do a lot of reading as well because I help my friend maintain his 15' x 35' inground pool. It has a sand filter but used to have a d e. filter. I don't understand how anyone could go for months without needing to backwash their filter... I can go for a month at times when the chemistry is stable and on point, the water is crystal clear and except for debris blowing into the pool and dirt carried in by swimmers that settles on the bottom and gets vacuumed up, even that will take a long time before increasing filter pressure enough that I have to backwash the system... My point is, unless there's some odd reason for the filter medium to become impacted or clogged if you will, to the point where back pressure is too much and the filter can't do it's job properly or efficiently such as cellulose in phosphate removers can cause rapid and unexpected clogging of the filter medium and require backwashing. Bottom line is the filter needs to be backwashed when it needs it... according to the increase in operating pressure when first started up or when cleaned after backwashing... Usually a 10 pound increase in pressure above the pressure when the filter is clean.
Hope my videos have been helpful.
This is a nice video, BUT -- I live by the rule that you should NEVER backwash a DE filter. The main reason is very simple -- although backwashing is easy and fast, it creates a complete mess by dumping DE powder all over the place where you drain the water used during the backwash....and at least in my case, that powder doesn't ever seem to break down or disappear. Also, when you backwash a filter, you never REALLY get the inside of the filter 100% clean (which is why you're suggesting to use less than 100% of the recommended amount of DE powder). For both of those reasons, I think it is well worth the extra few minutes of time to simply open up the filter, remove the grids, and then hose them off in a large tub. This captures 100% of the old powder, so there is very little mess, and it gets the inside of the filter 100% clean. I do this about 3-4x a year, and the whole process takes maybe 30 minutes from start to finish. Yes, backwashing would be faster/easier, but to me, that's not the best choice.
I'm glad that works for you. Personally in Arizona, I've never heard of any pool service provider doing it that way. But if that works for you, more power to ya.
@@PoolSchooler I live in AZ as well. You also have to remember those filter grids are delicate, I ruined a set by aggressively hosing them down. Use your lightest spray setting on your hose "gun" if you can.
@@johnvrabec9747 Absolutely. I totally agree. It's another reason I'm not a fan of DE filters.
@@PoolSchooler Well, I learned real fast not to use the old fire hose technique after that lol One day I'll tell you my story of my filter housing cracking and springing a leak when I was at work.
@johnvrabec9747 I think that happened to me today while at work. Came home water every damn where machine steady going. Guage at zero. Benn had a smal leak for like 2 weeks. Prior to today, I just washed the filters with the jet gun.
Thanks a lot for your very useful video. i have a question now. What do i lose if i keep backwashing until draining all the pool water? As a matter of fact, I'm thinking about using my only pump (filtering pump) to empty all the water into the garden. I have a small garden next to the pool and need to empty all the water into the garden maybe once a year.
Also please kindly let me know if you have any better idea for that (The main issue here is draining all the pool water into my garden without any additional pump).
Thanks again.
shaskhim I don’t think it’s possible because once the water level gets below your skimmer it’s going to start bleeding air into your pump. Which could damage it. I have heard of some older pools that you can do that with but most people rent a submersible pump and then following whatever county or city or homeowners association guidelines they drain their pool water usually into the sewer or, the street, but I would definitely make sure that’s not against the law in your area. Or they will drain it into their yard as you suggest. But I would absolutely recommend renting a submersible pump that moves a lot of water instead of using your pool motor and pump.
@@PoolSchooler At first, thanks for your very kind and fast reply. As for the skimmer problem that you mentioned, i can close it's tab so there will be no air problem. I have 2 separated tabs for drain the pool as the input of filter (one for skimmer and the other one for pool bottom drains).
I have a pentair Fns-48. I should be looking at adding only 5 scoops of DE to my filter?
TexasYankee if you’re using the same size blue scoop as I use in this video then yes.
After backwashing in the yard is the powder safe when it dries? I'm thinking wind picking it up and animals and people tracking through it.
It'd probably be a good idea to "hose" it into the ground a bit so the white powder isn't lingering. It's. yet another reason I'm not a fan of DE filters. It's not feed grade DE. Unfortunately.
Thank you for this! One question...I was backwashing and realized that water was still coming into the pool through the jets while flushing...is that normal? I would have thought it would only be coming out the discharge hose. Thanks
Oh, no it should all be going out the discharge hose. Sounds like you didn't get the back wash valve fully open. If it's a bit sticky try lubing the backwash valve o/rings
Pool School thanks for the quick feedback! So my backwash valve is a bit different from your video. It is at the bottom of the filter and is just a quarter turn for open or close. So I had it open as far as it could turn. It seemed like a lot of air bubbles and some water flow in my pool jets during the process. The filter seemed to flush correctly as the water got clear and I added the new DE, all looks to be okay. I am just confused about the jets.
@@davenirchi8161 Gotcha. I'm not familiar with that type of DE filter. So I believe I could not comment accurately on what you experienced. Sorry I can't be of more help.
Hi,
When I run the filter the DE powder goes back to the pool. I uninstalled, open the whole thing, clean it, inspected, there;s no rips on the grids anywhere (it's a new set of grids just bought last year). What do I do wrong? what's might be a problem? Thank you for your help. PS> I must do something right since I do exactly how you do in your videos :)
check your Hayward valve
