I wonder if its the freeze? I have a freeze guard and it is functioning. I heard water rushing tonight all of a sudden and went out and my push pull valve was up and my pool was back washing itself!
How does this happen? It's back in place now but I worry I'll lose a ton of water if it releases tonight. Luckily temps are supposed to be in the 40s on out this week so in the am I can hit the kill switch and figure out *** happened.
