I am replacing my water heater expansion tank. It is leaking at the weld (piece of carp). Anyway my question assumes the following:
H2O pressure measured at hose bib: 80 PSI System pressure recommended by expansion tank mfr: 60 PSI New tank max PSI: 100
My questions: Do I just add more air to get to 80 PSI? Is a small electric tire compressor ok or must it be a hand/tire pump?
TIA
