I noticed that hot water was back siphining when we would flush toilets etc. We have an old 2" well and pump, non bladder tank. So I put a check valve on the elec. water heater and it solved the problem and the elec. bill
droped $20.00 month. haven't had the pressure relief valve pop off yet and I installed the valve a few months ago. Question is should I have an expanshion tank ?
