Recently repaired solar panels...They had slipped down the roof and the joints were leaking. Fixed it all and now it seems that the water is not getting hot!?
Water seems to be flowing thru the system, have an automatic valve that is open, water drains down at night, etc. but the water coming out is the same temperature as the rest of the pool. Base pool water is 75 degrees. Things worked fine for the last several years...Any thoughts as to what I should check would be appreciated.
