This just started to happen. With the conventional pool heater off and the solar heater off the pool temperature is rising much higher than normal. Today it rose to 83 degrees with the air temp at 75 degrees.The pool temp is normally always less than the air temperature with no heat in use. The only thing I can think of is that it might be a bad return check valve. Its a 2" Flo Inc. swing valve. I haven't removed it yet to inspect it yet.
The Hayward Valve Actuator and valve on the suction side appears to be working fine and I doubt water could be bypassing that when off. Any ideas?
