    Pentair check valve flaps “dissolving”. Is this a common problem?

    My salt water pool has five Pentair check valves and one Jandy check valve. The pool is 14 years old. The Jandy valve has never been replaced and looks and works fine. The Pentair valve flappers only seem to last about three years. And cost like $75 - $130 each, and I need five each time...

    I have four actuator valves and four Pentair check valves in my system. I recently disassembled them for the first time since buying house. I think they are 12 or so years old. I found that every actuator had at least one stripped screw and same with check valves. One check valve, the screw...

    Simpler ways to prevent calcium scaling?

    I have a one year old SW pool w/ Pentait ECG. I'm getting flakes at the returns. It doesn't tast like salt (Leslies dude told me that's what it was) CL, PH, CY are good. Last month I cleaned the filter carts and inspected the cell. nothing in it. put in some mild acid/water. no bubbles. I...
