I am loosing water once the pump shuts off for the night. So based on searches from this wonderful site, I replaced all 3 check valves. I am still loosing water from the spa.
However, If I turn the pump off at night with the spa valves activated the spa remains full. My thought is it must be from the Spa Overflow, I switched the check valves to make sure. It only looses water with the spa off and the pool valves open. I would also think this rules out any leak.
As a temporary fix, I just program the spa to run for 5 minutes before the pump is turned off for the night.
What else am I missing? Where could the water possbily go?
Thanks in advance!
