Hello, I am replacing a failed expansion tank on my water heater. I checked static pressure at an outside hose bib and found 115 p.s.i.
The maximum charge pressure of the Watts tank I bought is 80 p.si., and maximum working pressure is 150 p.s.i.
Seems like 115 p.s.i. is a high static pressure, which would cause the capacity of the expansion tank to be overwhelmed from the cold supply side, (as opposed to the hot side where the expansion capacity is needed.
Any thoughts? Should I just fill the expansion tank to ~75 p.s.i. and go with it, or should I check static pressure somewhere else?
Thanks in advance,
John
