Hello, this is our second year owning our pool. I have a Hydrotools 1 HP 2 speed pump with DE Filter. This year after we opened the pool, I noticed the pressure decreasing on the inlet side of the pool after a few days. I put a brand new filter in this year. So I decided to take it out and clean it with a filter cleaner. When I put everything back together and prime the filter and pump, everything flows nicely for a few days until it slows down again. I know its not circulating right because I have a Frog System and the torpedo pack has been in for over a month and its not fully gone yet. I am reading different threads about dirty filters or an air leak somewhere. Since I have cleaned the filter once, and its back to doing that again, I am wondering if I should hard plumb the pool instead of using the flex hoses and hose clamps I have been using. I can turn the pump on high and it seems to run fine at that speed. Any suggestions?

The first place for us to start would be a full set of water test results. You would be amazed how fast a filter gets clogged up with organic material and you never even know it. Do you test your own water either a TF-100 or Taylor K-2006?

Is your pump a VS or 2-speed pump? If so, are you running on lower speeds when the water is dropping.
I only have a test kit that tests the PH and Chlorine levels. I was using strips, but found they were a bit unreliable.Welcome to TFP!
2- speed pump. When we installed last year, the guide the pool company gave me said to run it on low 24 hours a day and only to run on high when cleaning.
Also I should note when it seemed to be running normal, the pressure gauge would read about 2.5 psi. Now is about 5 PSI. on low speed.
Just verified that. It does rest on the pin when the pump is shut off.
88,
If the filter pressure goes up each day, then you do not have a pump issue, you simple have an algae issue. Even if you can't see it yet.
Pumps either work or they don't.
Please take a good read through our Pool School and see what we recommend you do when you have algae.
Thanks,
