Installing water heater expansion tank
I'm on a water well system & a check value is installed between the well pressure tank and the Hot water heater.
I think the check value is limiting the expansion of hot water & causing the T&P value on the hot water heater to open periododicly.
Will installing a small hot water expansion tank most likely fix the T& P value from releasing water?
What should I set the precharge pressure on the small expansion tank ? My well pump is set cycle on at 30psi and shut off at 50psi.
