2 years ago I had my inground built and it went great. Then last year we installed a heatpump for heating the water. It still went fine, but near the end of summer it started cutting off with HP error messages. I cleaned the filter, dipped it overnight, let it dry, it did the same. I even remember I took it out again to clean it with the shopvac and it still did it!
So I call the heatpump guy, he comes, and tells me the HP is caused by low flow, usually because cartridge filters restrain water too much. He even tells me to run the pool with no filter for a few days, and call him if it HP again. So it does it again, he comes again, now tells me my pump might now be able to pump fast enough. So I call my buddy that has his pool car company, he checks into it and tells me it's running ok. So the heatpump guy comes back and now tells me something like: Look, I'm a heatpump tech, not a pool tech. However, I don't think it's normal that the water is so low in your motor.
Effectively, you can see the water flowing into the motor. So I called the pool guy and now he says it's normal because it's pressure and it's boiling and blah blah blah. However, I tried running the motor without the basket into it for a few minutes and now the motor keeps its water! All I see is a bubble the size of a quarter!
Now, is it possible the motor basket is restraining the water flow by itself? or is it restraining the cover from being able to go back into is place? I was also thinking of eliminating all 90 degree angles and either install flexible pipes or 45 degree angles. Also, would I win something if I changed my whole apparent plumping for clear pvc instead of white?
thanks for the help!
