I have a pool with a freeze protection standalone box that seems to not be working. I really don't want to pay a pool service 80 dollars to come out and tell me it's not working then charge to install one. Is this something that is easily installed with proper safety precautions taken?
It has been below freezing a few nights this week, and it's not kicking on. it is set at 36 degrees and it was 31 out and the pool was off. Is there a way to test it better, or just assume it's not working. I will take a picture of it later and post it. I know it worked last season. The place it is in gets sun on it during the afternoon, but this was in the morning and it is shady on the box.
If i do need a new one, any suggestions on a basic, cheap freeze protector i could swap out the broken one for?
