Yesterday I was heating my pool getting it ready for today and I turned off the pump to clean out the basket and heard a weird screeching sound coming from the connections of the heater does anyone have a Jandy 440,000 BTU heater and has experience this also I know this heater comes with an optional bypass port Not sure if it’s on my heater or it came from that.1F91D13C-893B-47CF-BB7E-36BD0BCFEF86.jpeg

You should turn off the heater at least 5 minutes before the pump to allow the heater to cool. You probably heard some water boiling from still water and residual heat in it.
