How to REALLY fix a clogged Chlorine Feeder/Chlorinator
Вставка
- Опубліковано 15 вер 2018
- The short version is my check valve was clogged, and this video shows how I replaced it. The tablets in my Pentair Rainbow 320 automatic chlorine feeder were not melting down at all, and I couldn't find a video here that really specifically covered the issue I was having, so I made this video.
SAFETY FIRST! You could be working with harmful substances, chemicals, and poisonous gas here, so make sure you are correctly using the right PPE to do this job safely.
The check valve (and adjacent rubber gasket if needed) are pretty easy to find at most online retailers that sell pool supplies.
You helped me tremendously! I take care of my husband. I have to do household repairs on my own. I thought I had to get a new chlorinator. Floaters use too many tablets. I ordered the part and thanks to you saved the cost of a new chlorinator. Thank you so much!
That is great to hear! You are most welcome.
Thanks Will! I have the same chlorinator with the exact same problem. Your video told me how to diagnose the problem, how to fix it and how to test it afterwards. All in an eight minute video.
Thanks for this clear, succinct and helpful video, Will! Fixed my problem. I wish all UA-cam tutorials were this good.
Thank you, this is great info! One thing I would add is that old tubing WILL crack when you try to remove it! I am a pool tech, and nearly every time I have tried to remove and check the tubing for clogs, IT CRACKS and has to be replaced.
Thanks for the step by step instructions. We bought the parts and did it all ourselves, saved a bunch! Thanks for sharing. The tip on the screw was great we were about to juggle getting that back on, but you saved us!! Great job!
Made this fix this morning! took my chlorinator totally off, now floating tabs in pool.. thank you
Bro, awesome job and the only video out there, that I could find, showing that you have to take out the little flat head screw before you can unscrew the tube. THANK YOU!
Thanks for your comment! Glad it helped.
Very good video and explanation. Only tip i would point out is to lube those o rings so they do not have to be replaced as often. Use a non petroleum based lube found at any pool store.
For the last month or more, I have been fighting with my pool. Could not seem to keep it balanced. Noticed the tablets in my stack were lasting longer than usual, but I had just opened a new bucket that I purchased at a club store and not my local penny pincher. Was working on it this morning and when I checked the stack it was still very full. Found your video and it is exactly what my problem was. I popped the float down, cleaned everything up and reassembled it. I will be ordering a new valve and screen. I made it 19 1/2 years on the current setup, so I'm sure it's due. Thank you so much for this video.
Awesome! Glad it helped and you didn't have to pay a professional.
@@WillHennegan I tell everyone, "With UA-cam and a decent set of tools, you can fix anything!" "Well ,at least give it a shot."
Great video! I bought a Pentair 320 chlorinator on line (used). Of course I expected to replace gaskets and then watched a video that talked about all the parts and how to test them etc. That little check valve....WOW!. I just disassembled the thing and yep, my check valve is so dead. Everything else looked great. Gaskets were new as were the lines, so I'm not sure why he didn't want to do the check valve and call it a day and continue using it. His loss and my gain since I only paid $20.00 for it. I hope he's not reading this post.
Good score!
Fixed it in like 20 minutes no issues, thank you!
Superb video. This is coming from a commercial pool tech who trains new guys.
That means a lot, thank you!
Bet that is my issue as well! Thanks Will!
I just had this same issue and checked everything: the check valve, the flow into the canister, EVERYTHING! Then I decided to fill up my pool’s water level and I found out THAT was the cause of no chlorinated water flowing out of the canister. Hope this helps you if you are having this issue!
What do you mean by you filled up your pools water level?
You are my hero!
Great video - the very last second killed me! 9 tabs! That Cyanuric acid level must be 🚀🚀
Heh nope, all in range. The point of the chlorinator is to automate/regulate chlorine levels. I have it regulated down to a trickle through the tube. 9 tablets will last 3-4 weeks or longer for my 22,000 pool at 1-2 PPM.
@@WillHennegan 🤔 ok 8-9 tabs a month - that’s fair. No liquid chlorine or other sanitizers? That’d be wild maintaining residuals with only tabs that long. Unless it’s a covered pool or colder climate. Thanks for the response!
@@midstatepoolpro great points. I wish I could expertly/conclusively say how. Texas is hot and the pool is not covered. I may have to add 1000 gallons a week due to evaporation in the summer. I may also have to add 1-2 qts per month of acid to keep pH in check.
Thanks buddy. A lot of these videos are so so helpful, but yours was REALLY helpful. One thing, that black tubing, my old one had a kink in it because it doesn't want to bend. The new one I tried heating it and bending it but it is not working so good. Still working on it.
Would have been good to mention to also buy the little gasket at the bottom because it’s likely to be stretched out and need to be replaced. I used a mirror to help my eyes & screwdriver locate the screw head position.
I have been trying to fix this issue for many months. I replaced the screen, but that did not help. My pool maintenance company said that I needed the high flow attachment. The pool supply store told me I needed to replace the whole chlorinator. THANK YOU! Great video with perfect instructions.
Glad it helped! I guess a new check valve *is* a high flow attachment compared to a clogged one.
What I didn't mention in my comment was that I have been using shock to (attempt to) maintain the pool's chlorine level. I ended up buying shock from Costco that contained CYA in it and recently had to drain the pool to remove it.
I cannot thank you enough!
@@drrappon woah! Good catch. Yea, drain/fill is the fast and easy way to fix that.
Great video. Solved my problem for $8.
Will: thank you for video. The set screw was the trick. Pentair should just point their support page to your video.
Very helpful video. Thanks!
Thanks for the help
Seems easy
Great video! Just what I needed.
Great video! Thanks
Thank you for the video. Very helpful
I just took a flat head screw driver and poped the ball down. Works just fine.
Thanks! Great Video my exact problem. Great Help!
That NIN reference lol
I'm having a REALLY hard time removing the feeder body. Any suggestion? I already removed the lock screw on the bottom. Lots of white stuff is flaking off onto the ground (presumably calcium) after turning it 360° -- muscles and hands are sore. I already ordered a new 320 system because many parts have broken already during this process of checking the check valve; I have the same symptoms you described. My existing 320 system may have been 15-18 years old. I'm receiving a strap wrench in the mail today but am still not confident I can remove the old body.
Yikes! It sounds like you may have a lot of corrosion or buildup, or possibly your pool installer used a PVC adhesive to connect the tube. The way this is designed, there's no easy way to get a solvent in there to loosen stuff up. A strap wrench will either work, or flat-out break the unit, but worth a shot! If you cannot manually unscrew it, you may need to cut the unit out, and plumb in a new one anyway. Good luck!
@@WillHennegan Yes, while using a strap wrench the cylinder cracked so I had to buy a new 320for $158 during the worldwide product shortage! The price is now a lot lower. My 320 is still not working though. It's not the check valve because I'm using a brand new one. I'm not getting flow and chlorine tablets are not dissolving.
@@tponce Gosh that sucks to hear. If the 320 is filling up when the pump is on, and draining when the pump is off, then there is nothing wrong with it. When you say you are not getting flow, do you mean the column is not filling? The only other problem I could think of is that the unit's diverter tee was installed backwards. Can you verify that? There should be flow direction markings on it. Good luck!
Thank you Will for this video. Water won't stay inside the tube while the pump is running. It slowly drains out leaving the tablets without any water to dissolve. I cleaned the screen. Any other suggestions?
If water won't stay in the tube, it likely means it is slowly draining out of your pumps/filter too and you have a system leak somewhere. When everything is running, look for water drips/leaks. Hopefully it's just something simple like a poorly seated or broken gasket seal on the chlorinator. You may have to bring in a professional to track down the culprit. Please post an update here when you figure it out. Good luck!
hello Will, very useful video, one question, where you got the check valve? do you have a part number? thanks in advance.
Mine is dry all the time, the feeder is at the bottom plug and the water gets maybe a few CM from that and the tabs last forever! BUT if I take the top off the chlorinator fills instantly. Is my valve dumping the water as soon as it comes in or is the valve stuck open? And when I pop the top it closes the valve?
Start your pump system then leave the cap off the chlorinator until it's full, then close it. Since it's a sealed system, the air won't escape unless you let it.
My chlorinator does not fill that fast no matter how much I open that valve with the numbers. Trying to figure out why no chlorine is getting into my pool the last 2 days :(
You may have a clogged filler hose or valve. Can you temporarily disconnect it at the bottom and see if water shoots out of there when the pump is operating?
@@WillHennegan I dont know. I am a fairly new pool owner. I may just have to call a pool company
If I soak the check valve in vinegar do you think the ball will get loose?
I tried soaking it in CLR with no luck. Vinegar is definitely worth a try tho!
@@WillHennegan My valve was filled with small plastic pieces so vinegar wouldn't have helped.
I like you, will. Lol well done.
I just found my chlorinator is clogged as well. How do you go about removing the screen? My hands are small enough to reach inside but I cannot get a good grip on it. I've also tried tongs but with no luck. Any advice?
You might not have to! If it's stuck well, just leave it :). Mine was loose so I removed it to properly re-seat it.
@@WillHennegan thank you for the quick response. Do you suppose it's the check valve then and not a clogged screen?
@@tnguyen308 If you can see through all the screen holes, it is probably the check valve. If you want to be sure before ordering a replacement, just remove it and give it a shake.
@@WillHennegan thank you so much for the video. It was indeed the check valve. Would you know how often that would be to be replaced? We haven't had our pool for a year yet and had to replace it.
@@tnguyen308 I had to replace mine in less than a year as well. I would hope a simple part like this would last 10 years, but apparently that's too much to ask. :(
Did everything in the video, water still wont drain. What now?
If you have the chlorinator removed and fill it with water, does it drain from the bottom check valve immediately? If not, your new check valve is bad. If it does, then your chlorinator is probably fine and there's a plumbing issue downstream.
Quick question, water is not draining from the Chlorinator when pump is turned off....any suggestions? Also im seeing a water leak just above the pentair logo. Its coming from the attached section. Any suggestions?
Hi Miguel, if your chlorinator is not draining when the pump is turned off, your check valve is likely clogged (the exact problem I had in this video). I would recommend going through the same replacement procedure I did. You could address your leak at the same time by replacing any old/worn thread tape on connections, and make sure all gaskets are in-place.
If your equipment is below the level of the pool, this is normal, as you are likely closing the return valves to open the chlorinator so that the pool water isn't backflowing. Per the Rainbow manual, you will need to install a drain at the bottom of the chlorinator. This is common when the pool is built on a sloped site and the equipment is on the lower side of a retaining wall.

Very helpful video! Thanks!!!
