The first step I would take is to check if the gauge is still good, preferably by using a recently calibrated liquid filled gauge.
If the calibrated gauge gives you the same values as the one currently in place the issue lies elsewhere.
Among the thoughts here are a defective gauge currently in place, a defective pressure relieve valve currently in place, or perhaps the relief pressure on the current valve having been set improperly.
Those would be the first steps I would take.
hope that helps,

My fire system has a pressure level dial by the pressure relief valve. The reading on the dial went from 150 to 175 yesterday which is when the relief valve is supposed to open. Not to take a chance, I manually opened the relief valve for a minute. In the past, this would reduce the pressure shown on the dial, but now the dial needle stays still. I confirmed that water did flow out as normal. Has the dial gone bad or do I need to call someone to inspect? I’m always concerned if the pressure gets too high because we are in Arizona and the attic gets stifling hot. Thanks for your help!
