I was told that it should be between 18-21 and mine is at 40.
Levowen thx. I just had the expansion tank and pressure reducing valve replaced due to the tank was leaking water. The plumber informed me of the guage problem. I am now waiting to see what PSEG says since the pressure/temperature guage should be covered under warranty.
