I am taking care of my neighbors pool. A leak developed in the heat pump.
My neighbor never uses the heat pump to heat the pool. She never goes in the pool, ever. There is a bypass valve to the pump with a handle on it. When a leak started I tried to move the bypass valve but it would not move. The pool cleaning technician had removed the handle and replaced it incorrectly so the valve was always diverting half the water through the pump. He had to strip the handle on the valve to make it fit that way.
I replaced the handle so the heat pump is no longer receiving any water though it so I could fix the leak (just a cracked hose leading to the pressure switch).
This morning when the pool cleaner came back he changed the handle back the way it was on the valve and the water is partially going through the heat pump again.
Am I wrong to cut off the water completely from the heat pump while it is not in use?
