We have an in ground finite pool. Underground plumbing located approximately 40 feet away. Triton filter, 2" piping. Afternoons pump flow priesthood at full force and drops to about half flow after several hours and continues at 1/2 - 1/3 flow. Pressure seems higher than normal on the filter. The baskets are clean so nothin is clogging or blocking TH flow that w can see. SUGGESTIONS???

It sounds like you may need to clean your filter, it would help us if you would put your pool description in your signature (see your profile settings) like I have mine.

Sorry the Kindle was substituting words. It's a 36,000 gallon gunite pool w a Triton 3.75 motor. We do backslash regularly. Do you mean take it apart and put in New sand?
No, backwash is fine, Check the pressure gauge on the filter, see if it goes up while flow goes down (turn off pump and make sure gauge goes to 0, it may be stuck and need replacing) If pressure goes up on the filter while flow goes down you may have something growing in your pool. Do you have one of the suggested test kits, and if so can you post a full set of test numbers?

Here are the resultsChlorine 3.0, PH 7.2, Alkalanity - couldn't get a reading. Stopped adding drops after adding 15.
Thanks for your help on this. Bill

What test are you using (is that chlorine level FC or TC?), and do you know your CYA level?
What is your clean filter pressure and where is your pressure when when you are at that low flow condition?
What is the pressure reading when the pump is off?
Do you have air in your pump basket?

We redid the tests. Chlorine OTO test reads above 3 maybe close to 4 or 5. ph is 7.2. Total Alkalinity is 80 ppm.
Last year the pressure was 25. This year the pressure is 30. At half flow, it is bouncing between 34-36.
Is the water green or cloudy? Maybe the filter's just doing what it's supposed to do?cawwjw said:
This is almost certainly a sign that you need to backwash and something is likely growing in the pool. The OTO test only tells you total chlorine, it does not break it down into FC and CC like the FAS-DPD chlorine test (elevated CC is a sign you have something growing in your pool), also without your CYA level we can't know what our target / and minimal FC levels should be.

Thanks we will getthwatertested. The water is very clear though but we will heed your warning. Thanks!
Does the gauge go to zero when the pump is off?
30 psi is pretty high...what model pump and exactly what model triton filter do you have?
