I have gotten several people who struggle with changing all of the filter grids in their top manifold D.E. filter. Some have had D.E. leaking back in after replacing all eight grids. Here I show you the easy way to do this procedure.
If you have already taken all the grids out and the filter is apart:

I am changing the grids here in an FNS Plus filter but it is the same for an American Products D.E. filter. It is essentially the same for the Hayward and Jandy filters except they have one rod down the middle which is actually easier. The newer filters will have a nice plastic guide to help you align the top manifold.
You see me tapping the top, as long as all the grids are aligned and in place under the top manifold that is the easy way to get the top onto the grids. You won't break any grids that way. They will snap and break if the top is not aligned properly and you go to screw the top down with the nut or bolt on the rod (s). So make sure they are aligned before you screw the top manifold down. I find tapping the top manifold to be effective.
After you got it all back together and you charge it up with D.E. and it leaks - it will be one of the following problems:
1) A grid snapped on top as you where putting it back together
2) The stem o-ring was bad and isn't sealing the stem pipe.
3) The stem pipe could also be cracked and leaking.
4) The backwash o-rings are worn - replace the backwash piston or you can
also install new o-rings onto the piston. If it is 6 yrs or older just replace the entire piston.
5) The top manifold is not snug and some of the grids are exposed allowing D.E. back into the pool.
These are the usual problems if D.E. is leaking after you replace all eight grids. It is pretty easy if you do it this way. If you take all the grids out and try to build it outside the filter -- it is more challenging. I can do it as I build these all the time but I always build them like this now.

Thanks for this video. Just followed it to the letter and had the pool up and running in less than an hour and a half. You saved me a bunch of money too. Really appreciate the time and expertise you put into making these videos.
That's Great!
Watching this saved me a lot of time and heartache! Thank You
thanks man, i’m a new service tech for pools and i’ve been thrown into this stuff after only one week of training. video helped me understand a lot
Omg. I love you. After draining my pool, cleaning (scrubbing) off the algae, pressure washing my entire pool, taking apart the Hayward DE filter, breaking the manifold, cleaning the filters, and fixing the ball thing for the pop-ups. I was putting everything back together. All within 24 hours. But I couldn't get the top back on to the filter. After 2 hours and one stripped 9/16 nut I almost broke my toe kicking the filter. At 33 years old and 5 years being a home owner, this project was my nemesis. So I looked on UA-cam and found your video. Fast forward to almost the end to watch you put the top back on. Then you said it!!! "Lube up the O ring" . I ran into my garage, grabbed some WD40, came out and sprayed it. BOOM! Went right into place! It never even crossed my mind to do that. Thank you for being so detailed!
Mike.
Should have used silicone.
Thanks for the video. I have been having ongoing problems with my Hayward filter, and your video gave me the courage to order a new set of grids off of eBay and install them. I put them in this morning without a hitch. The surprising thing is the degree of improvement. Really stunning how robust the water flow has become and just how quickly the pool is clearing. Your major tip--replace the grids one-at-a-time as you take the old ones out--is one of those things that seems obvious unless you didn't think of it--and then it's too late!
Your pump and filter are the brains of the operation if you have a bad spider gasket(which allows water to flow in all directions instead of the position you have placed your valve into) or old and/old gets then the water can't properly filter it's like using the same Brita filter for months or years without replacement or your air filter in the home. The air/water quality will decrease in purity
Your vids are ALWAYS trustworthy and highly credible! Thank you so much!
Uhg. never occurred to me to do the grids in/out one at a time. wish I had watched this first. Thanks!
You are my hero! Your videos are excellent & very helpful. My pool people are crimanally expensive. Ty.
DE Filter Grid Replacement How To Video -The Easy Way: Need to replace your D.E. Filter Grids. You can do it nice and easy with everything still in the filter tank. Watch and see.
This video made what seemed like a complicated task very easy. My guide was worn and not gripping very well so I tied a little twine to keep them all lined up. Once the filter cover was off maybe a 20 minute job to swap all the grids and put it back together.
Glad it helped!
Thanks to your videos I fired my pool guy and now im the the guy doing all the maintenance because of your videos. Thank you
Excellent, I have been pulling the dirty HEAVY element out to do the job, now I know how to do it in place. Real back saver! :)
Great videos helping diy pool owners take care of their systems. One recommend I would make to anyone messing around with the pentair filters is to wear a long sleeve shirt and gloves. The fiberglass shells wear down over time and are not fun to touch against your skin.
Question - I just replaced the filters and manifold using a full replacement kit. My pressure hasn't really gone down since before replacing it. What are some steps I can take to troubleshoot? My gauge reads 30 when I run on full filter/skimmer, and about 15 when I run the vacuum and skimmer. Suggestions?
+Ryan Goodwin Cold be back pressure from the return lines. How is the water returned to the pool - how many return jet and do you have an attached spa?
And the fiberglass can be a pain. Ironically a fiberglass pool company was re-glazing a pool and they gave me a good tip, wrap Costco or Sam's Club Saran wrap around the top of the tank to protect yourself from the shards.
A tip from a pool repairman suggested I spray paint shell/housing. I did and seems to be fine. No more glass debris to contend with.
another great thing to use if you get fiberglass on you is to use duct tape or masking tape.Just slap the tap on where the fiberglass is on your skin and rip the tape off. You will see all the fiberglass in the tape. It works wonders.
Great video! I replaced my grids just like you said and the job was super easy! Thanks!!!
2021 and still going strong. On my honey-do-list. THX!
As always, the best videos available. Thank you.
This video was very helpful - thank you for taking the time to make it.
Just wondering why you wouldn’t make sure to tell your audience that your need to use DE Powder when your done cleaning the filter. DE Powder: When diatomaceous earth is introduced into the pool filter system, it coats the filter cloth. As water passes over the filter grids, the DE particles capture even the smallest suspended dirt particles. When cleaning is needed, the water flow is simply reversed.
I just replaced all the cartridges in my DE filter. I had 1 hole in 5 of 8 old cartridges. I’m sure my pool water will look amazing now.
Yes sir Mr. Bean. 👍
Thanks for your video was having a little trouble getting mine back together at first, of course I just took out all the old ones to throw them away, and then was having a little trouble getting it all back together.
The engineering on this thing is maddening! 😜
I really love your classes. I have a question, I hope you can help! I clean the filters and all runs fine for around 3 weeks then the pressure in water gets week. We have a Spa that spill over the pool and that cascade gets very week and eventually stops. Do you know what can cause that?
Thank you again for posting your videos
Thanks for the great feedback. You might simply just need new grids. They last about 3-4 years and when they get old they can cause this issue.
great video ,I was sure i'd screw it up ,but replacing the grids on my fns 36 went smoothly . thanks
Nice. Over engineering at it's finest! 😜
Very nice. I just checked out their website.
Good video. What should my pressure gauge read after replacing filters and de ? I’m a newbie pool owener.
Usually around 20 psi
@@SPL thank you. That’s what it’s showing so looks like I’m good. My pool looks fabulous
When you do it, it looks too easy.
Question, o had to clean a “Hayward” filter today. Removing the grids was easy, however when I had to place the grids back on the manifold, it was difficult. I had to do it “up side down. (Placing the top manifold at the bottom and bottom manifold on top.) I’ve spent almost and hour trying to figure it out. Could you make a video on the proper way of doing this type of filter. Again it was a Hayward filter grid. Thank you.
Very straight forward process. However, I just order Pleatco Brand filter grid set for my Pentair. I have a Pentair FNS Plus, 36 sq feet. I put the grids in, and the top manifold doesn't line up with the notches in the grid on the top end. What do I do. I need to find these asap.
Do you have any videos on placing the “GRIDS” back on the bottom of the manifold?
Awesome video...thank you very much!!!
I cleaned my system and all the grids but when i added DE it pumped a large amount back into the pool and it was cloudy. Not sure what happened here. My pool guy said my tank like the one shown in video needed a 25 bag of DE. I backwashed, cleaned all the screens. I think maybe I added too much at the beginning? I guessing a bunch passed through and into the return line?
25 lbs is over twice the reccomended amount.
I went ahead and replaced all the grids, because 5 of the 8 were torn. I put it back together and the pressure went to 10 like it always does after I clean it, but it has climbed to 15 in a few hours. Did I do something wrong? I have a 36 square feet filter and I put 7 scoops of de.
I wouldn't worry unless it goes up higher.
Walmart - $3.00. I use all the high tech stuff ;)
If de is being leaked into the pool should I replace all of them or only the ones damaged?
Only the damaged ones.
What is the spray you’re using? I can’t push the manifold down. Too much resistance
Rv grade silicone spray. Change that stem o-ring also.
Great idea to do it one by one like this!
Great and very helpful videos, thank you. I found a torn grid and bought a kit to replace all of them on the fns 48. When I took it apart I noticed that one of the rods that holds the manifold had rusted away and is no longer attached. I purchased replacement rods. How would you recommend I go about replacing both rods and not running into problems replacing the grids? Thanks in advance.
This video I filmed but haven't got around to editing it. Got about 70 videos on my HD right now so a little back logged fortunately. Pesky full-time job is getting in the way...
Try to pull the complete unit out - cleaning it off if it isn't already will make it lighter and wait a day for it to dry out.
Once you have the unit out - top manifold with grids intact - turn it over so that the small bottom manifold is now on top. Now slide the new rod in and tighten it from the bottom - which will be the top manifold. Does that make any sense?
I have a question I replaced the filter grids following your instructions and now I am getting the DE powder on the return air line inside the pool from the bottom of the pool so I’m not sure where it is leaking from. Could you please help?
Check the manifold maybe or there may be a torn grid that was missed.
Hi Thank you for the great video... I just replaced my pool filter grid and manifold together at the same time, I never had the problem of getting a high pressure, now the pressure goes up very quickly to 20 psi, then 25 psi and flow from skimmer and bottom valve decreases a lot. But when I run pool in Recirculate it doesn't. This only happens during filtration. Can you please Help, when I backwashed pressure drops to 10 psi then it raises quickly to 25 psi.. why do you think is doing that..?
Did you add the correct amount of D.E.? That can effect filter pressure.
gold! this video is gold! saving me $$$$
Are there supposed to be little rectangle pieces loose at the bottom of each grid fin? Can't tell if I need replacement... Thanks in advance for your help.
Shouldn't be loose.
didn't think so. ordered a new set. kick off this season correctly. thanks for the reply!
Hey man I know this is a old video but it was great and straight forward.much appreciated.at the top where the manifold meets the grid is it normal for the grid to slide up and down in the manifold insert where the grid goes inside the manifold?i have one or two that don’t seem tight and has plat but are lined up on bottom of grid assembly?i put it all back together and filter is running and seems ok.just want to make sure this wouldn’t cause a issue
Typically it should be on tight but if no DE is getting into the pool you are fine. 👍
Do you have to fill half of it with water before filling?
No, filter should be empty when you put the lid on.
Whoever thought this design was a good idea needs to have their toenails ripped off one by one
Great video thank you that was very helpful
Aside from the small grid, are all the other grids interchangeable?
yes.
@@SPL thanks again man! Big help!
What is the spray you used for the orings i use the small bottle of waterlube. Never seen a spray
It's Silicone spray. Boss Brand or any RV grade silicone spray will do.
@@SPL why are you using silicone instead of a water based lubricant? Bc it's a clamp instead of bolts or bc it's an offering with s metal ring on the inside like the Hayward 4280? I've always put water lube out magic lube or just any non oil based lubricant on o rings
Thank you for the help
I was wondering if I should replace my de filter entirely or just replace the grids. I have a nautilus NS-36 and I know that the "partial" grid needs to be replaced because the plastic piece that attaches to the top manifold is broken but wasn't sure if I should replace all the grids/the whole thing since it's an old filter. Also, it's leaking DE into the pool. Thanks for any insight.
If the tank seems okay and the filter is the correct size for the pool, then just replace the grids. Cheaper and will solve the DE leak.
What is the black grid after taking the filter girder
That is the top manifold.
Could you just open relief on gauge and wait until at 0 and remove clamp and there will be no water loss???...i do it like that but maybe I've been doing it wrong all along...
You can also. Some DE might go back down into the pump though.
How do I figure out which one to manifold to order?
Each filter brand has a different one. What brand is your filter?
Great video! - can someone explain where on the system he is putting in the “DE” (time stamp 10:19)
Into the pool skimmer.
I cleaned the filter why does the pressure rise to 30 really fast and the filter gets dirty quick
Sounds like the grids are bad
I suppose you can use the same method for just cleaning the filter grids as well?
+rodsta_o Yes. You can hose around the top manifold or remove it and clean the grids inside the tank.
Thank you for your video. Smart.
I have a Titan rpm vertical grid de filter 60 sq ft would the same grids you used work with it ?
Yes. They are universal.
Why do you always make sure the filter is completely full before you open it up, and then let the water spill everywhere out the sides, rather than draining it before you open it so no water spills? It's not how I do it so I'm wondering if I'm doing something wrong, if it's just personal preference, or what.
Anyways thank you for the videos, they are very helpful.
I don't let any of the diatomaceous earth water come out. It will dry around the area and then you will breathe it .This is dangerous. Unless you can hose the area into a drain i would never let the water slosh out like that. GREAT POINT for people to know about.
If you want to keep DE from drying around there then wouldn’t you avoid splattering it all over the walls and begin by using the hose w/o the spray head to wash down the DE that settled on the top of the top manifold down into the tank? You’re being Mean disingenuous. You’re doing it for speed. It’s easier to get the top off a fiberglass tank with a dry sealing ring with the water in the tank. The plastic tanks flex a lot and the top is pre-loaded to be tight st the seal. The gasket and the tank last a bunch longer if you back off and tighten both tank nuts evenly. The predecessor, the stainless American Titan/Pentair Nautilus was stiff and only needed a one-nut tank band. They didn’t change to a 2 nut tank band because it looks cool. The WD40 (originally US Army Water Dispersant 1940) is a very temporary lube but spraying it on like that at close range also applied the spray propellant and that will soften and swell the rubber seal. That’s why it elongated so much it almost pushed a loop out to get pinched. If you want the lid to slip into place w/o pinching the seal and w/o leaving a lube and w/o swelling the rubber the lanolin o-ring lube used for large diameter won’t degrade the rubber and it’s no more hazardous than sheep. Dishwasher rinse aid will also do the job. Both wash off hands and tank easily and cleanly.
If you want to leave a lube behind then one of the styrene modified greases like aqualube but it doesn’t rinse off hands.
As long as I’m being picky, i’ll also point out that the grid clamping rods don’t always cooperate like that. Sometimes they spin and remove the nut on the bottom instead. A needle nose pliers won’t always keep the rod from spinning but it lets you know the assembly has to come out so you don’t have to fish for the serrated nut in the DE muck.
@@oliverstreet7704 NOt mean and disingenuous at all. DE is not to be inhaled period. I can not hose it away and many people cant There is not always a drain by the filter. Not sure all the stuff about tightening things. Your filter may be different from others. I just want people to know they should be careful with DE Thats all. Sorry you thought i was being "mean" Pretty sure i was trying to protect people. You are remiss in not addressing this.
i have an American Product Titan CM filter, 60 square feet one, but the clamp is all bent out of shape and it's hard to put it back on without the use of a nut i had to buy to first tighten the clamp before putting the nut and barrel, and that clamp is impossible to find now because it's no longer in production and i can't find a belt that's 22 inches in diameter, is there anyway i can use a different model clamp? i just need a damn clamp to make it easier for me and no need to use a nut that gets rusted so easily
email me a photo and I will see if another model will fit. davidginavb7@gmail.com
thanks david, i havent taken off the belt but it says on the web it is 21-22 inches in diameter, while the height is around 1.75 inches, my filter is the American Products Titan CM, installed prior to the company being called Pentair, this is the link
www.inyopools.com/Products/07501352014433.htm
What tool did you use to unscrew the 7/16 bolts?
Multi-tork
Is it possible to put cartilage filter instead? these are a pain
No, you would need to replace the entire filter since a DE and Cartridge filter intake out outlet are reversed. But yes, these are a pain.
Dave, being proactive instead of reactive, when is it a good time to replace the DE grids? Is 5 years too soon? I'm able to purchase the complete Pentair DE grid kit for around $300 which isn't a bad deal.
Every 3-4 years is optimal. Good price. 👍
Swimming Pool Tips, Reviews & How To - SPL Thank you!
Which filter (Pentair or Hayward) do you find is the most forgiving to the new DE user? I am a cartridge filter owner going to DE.
The best DE filter on the market is the Pentair 4000 series. It is more expensive but a sinch to clean. The manifold is actually on the bottom so you can easily clean it. The best for sure. I have a video on cleaning one: ua-cam.com/video/XWIltRenwC8/v-deo.html
You can see from the video how easy it is.
I've been in the swimming pool service industry for 12 years and I manage a pool service company in Dallas and I would recommend the System3 72sq.ft. Modular DE filter. It's basically a cartridge filter that you add DE to. It takes about 20 minutes to clean from start to finish and is SUPER easy to do yourself. It only has 1 cartridge in it.
I have a small pool with an OLD stainless steel 36sqfoot filter. I can't get a seal on the belt. I lubed the rubber ring, and did some adjusts to tighten, but no dice. I still get a couple thin slow streams.
I did notice that it has couple mm cracks at the outer lip on the bottom bowl. two of them, almost oppiste each other. The lip where the Oring sits up against. It has an inner stainless ring as well which looks good, and the top looks good too.
This design has no backflush. I'm wondering if I can correct this, or should I replace this? I don't want to replace it as I don't plan on spending over $300 for a new filter, and all the new ones are plastic, and have no idea how long they will last. A Pentair4000 series was $700 on Amazon!!! Ouch. My pump is pretty old too, and I have had it screech a couple times. Help
UnknownHandle UnknownHandle I'm open to advice, and I know the default.... "Ya, that is an old pump, you might have to replace it", but looking for alternates.
btw, I watched a few others and their videos, you have a good way of doing what you do! Bravo!
UnknownHandle UnknownHandle Did you change the o-ring? Usually that solves the problem.
UnknownHandle UnknownHandle I don't recommend replacing pumps until they die. Just swap out the motor - less expensive. And keep the motor until the screeching becomes constant and annoyingly loud.
Swimming Pool Tips, Reviews & How To -MrDgvb1 The Oring is faily new, and lubed. I'll check if its sitting correctly. But I used to barely get the clamp with nuts to come about 1/2" apart, and it would be a good balance to keep it from leaking. Now the 2 halve circle braces are almost touching when I tighten down the nuts.
Swimming Pool Tips, Reviews & How To -MrDgvb1 My "pump" is so old it is just a motor...bolts on to a metal screen basket. 1.5HP, and right now, but it works. Only screamed at me 3 or 4 times :-) I think I need to plug off the suction at the bottom of the pool to get the scimmer suction high enough for my cleaner; Baracuda G3 meter to show any suction. As of now that spring doesn't move, let alone get to "3" as recommended for the vacuum cleaner!
Hi, Can you recommend a good online dealer for grids? I have a 40sq ft Pentair/ Whisperflo filter. Ty very much.
Check out INYOpools - they carry the grids and the whole grid assembly for a great price point.
@@SPL Many thanks for your help & videos. You are the best. Wish you were in my area. Ty.
@@SPL Got those grids & a new O-ring ! Fast delivery & a great price. Ty.
do you recommend emptying a pool out for the winter or keep the motor/filteration system working during the winter when the pool is not in use? Our past pool guy stressed that emptying the pool might damage the motor when we fill the pool back up after non-use.
We don't winterize pools here is Southern California - but those that do in other parts of the country leave most of the water in their pools - they just blow out the lines so water doesn't freeze and crack the pipe. Google it and there are several videos on Winterizing your pool.
Thank you for your expert advice and for your wonderful videos. They are in detail and easy to understand.Swimming Pool Tips, Reviews & How To -MrDgvb1
Never empty a pool out for the winter,unless it's an Intex or equivalent
Even then you don't have to,the covers that come with the Intex 15x48 are very hard to keep tied for the whole winter but if you're able to keep the cover on your pool you should be good for the winter whatever part of the country you live in
So no need to take the grids out of the filter ever? Replacing or cleaning?
That is basically the premise. The grids will last longer this way and they are easier to replace while in the tank.
What do you think about using cellulose instead of DE?
Where did you order that kit from?
DE is the best still I think or Perilite. I get the grid set at my local wholesaler.
How often do the grids need to be changed?
every 3-5 years.
This is by far the hardest way to do a filter clean. I understand disassembling the grids in the tank, but why reassemble them in the tank? It becomes very hard to see the grooves... not to mention putting that manifold back on looked ridiculously hard. I have never seen it take so long to put a manifold on that has stationary rods and a guide for the grids. Just my opinion as I have been doing this for 8 years.
Your opinion is noted. I do have one that I filmed where I build it upside down outside the tank but haven't edited it yet. As far as the top manifold - going slow for the video.
So what method did you recommend? I found it not too hard to do this way but I had to get the filter out where I could see it easily and just started with the small grid against the pipe and then with the next one behind it a little to the left and so on and you could easily see where each grid ended as it had a little stop in the plastic grid on the bottom.
Thx for the video!!!
Is there a certain pattern they should go in?
Yes. They only go in one way. You will see the pattern marked on the bottom manifold with the partial grid going in first.
This may be the easy way for an octopus, but there is no way you're going to align all eight of those filters (how much spare time to we really have folks), plus two stainless rods with that whole thing in the canister. I was able to get all of the plastic lined up just to find that the rods fell down to the bottom (but still too long to maneuver into place). Once I removed this rube goldberg from the canister, I was able to manipulate the rods, tightening one then the other. Appreciate your videos Dave, but this one needs some work.
+Gary Gross (garyATeightyoctane) I like that "Rube Goldberg," heard that referenced before with other pool equipment. Those rods have locking nuts on the bottom manifold to keep them in place. But sometimes they fail or are put in wrong after a filter tear down and cleaning. I did film an alternate way for just such an occasion.
Replacing all Eight Top Manifold D.E.
Filter Grids THE HARD WAY: ua-cam.com/video/WnigS2BFrUc/v-deo.html
How the whole kit cost?
Prices Vary. Usually $300-$400
Was that spray can wd40?
RV grade silicone.
What is the size of the clamp nut?
Do you mean the threaded inside part of the nut? Not sure. But if yours is worn out I suggest just buying the factory replacement as I've seen filters pop open if other nuts are used: www.amazon.com/Pentair-53108900-Assembly-Replacement-Cartridge/dp/B002NJK72C/ref=sr_1_1?ie=UTF8&qid=1406488241&sr=8-1&keywords=pentair+fns+plus+filter+nut
Wouldn't this method create a huge mess in the customers backyard? Other than that, it seems like the best way to go.
How much should I charge for that job?
$30 per grid - $100 for labor.
What's the hard way?
when you try to assemble it outside the tank.
Didnt take the drain plug out. Backwashing wont get out all of the old water.
Ken Coup what do you suggest then as the proper procedure?
I’ve been in the pool industry for 16 years. Sold my route in Las Vegas to move to Texas. I’ve never seen a DE filter in Las Vegas. These are a complete waste of time and money. The same profit (if not less), for cartridge filter install. $300 profit for cartridge in 10 min of work, less profit for an hour worth of work. Note to self: Stay away from DE. Less money more work!
Sounds like you will be selling your D.E. filter customers new cartridge filters. Here in CA is is about 60% DE and 40% cartridge. I prefer cartridge aslo.
There is no easy way to do this friggin job, especially if there is not a guide ring! Might be better if the assholes came up with a better design but then they wouldn't be able charge people up the ass to come and do it for you when the average person messes it up and cant get it back together!
I am with you on that. The design of these filters are meant to cause you to break the grids since the tops are fragile and to cause brain aneurysms as you try to rebuild it... I like the Pentair 4000 series filters as you can easily remove the grids and clean it. These are horrible. Well said.
We just took ours apart and put it back together without any of the expletives you just used... and had no problem. There is however a newer version that holds just four cartridges up right that would be easy enough for anyone to dismantle, clean and reassemble.
I had a pentair that was much like this one but smaller. It wasn't easy, but it wasn't hard either. Then I moved and the new house has a Hayward. The grids are 100% more difficult than the Pentair. Even the drain on the Hayward is more difficult (and less efficient) than the Pentair. Can't wait to swap the entire system over to a Pentair.
Cannot agree more!
One last thing, what the hell is a partial grid.
Partial Grid is the one small grid of the eight. It is about half the length of the other girds. Odd that it is not lining up. Send me a photo and I can have a look.
Sorry to get back so late. I just ended up returning the grid set, and ordered an assemble one, with grids, bottom and top manifold. It was just drop and go.
Luckily I already had lube ;)
KY or astroglide?
Worse system ever, junk
thank you for your help.
I'm coming from a sand filter so it may not apply. But how often do you replace all the de?
TYpically every 6 months in a DE filter.
@@SPL thanks you :) like a full on empty throw away and replace
Swimming Pool Tips, Reviews & How To - SPL clean every 6 month or replace every 6 month?
Does it pay to swap all eight grids? How about chsnge the whole assembly? I have an in ground pool and spa with a D E type filter.
If the top manifold is looking old and has some small hairline cracks in it, it is better to purchase the entire assembly. But if only the grids are bad it is less expensive to just replace the 8 grids.
Swimming Pool Tips, Reviews & How To -MrDgvb1 Let me ask you. Is it possible for the D.E. to leak through and out into the pool? When I brush the floor or sides, I keep seeing a cloudy sediments.
SpyroTDragon it's definitely possible for DE to leak out into the pool, that's what was happening to mine, I thought it was sand in the bottom of my pool because it was kind of beige which is basically dirty DE powder but when I try to pick it up, it's a fine powder that you can't even feel, and not the granules you would normally find with sand. That generally confirms a finding of DE powder, so that's what I inspected my de grids and found at least four of the grids had tears in them allowing DE powder into the pipes returning to the pool and actually blowing out into the pool.
