When we lose our potable water due to a break in the line, the water siphons from my unit and the desuperheater pump can run dry. I am thinking about either flipping the dip switch for the pump, or taking the lead wire loose to protect it from this happening. Which option would be best? I have installed a check valve in the supply line trying to prevent this but its still bleeding off. Thanks in advance for any advice and Happy Thanksgiving!
