. You need to replace your PRV if you have one, It's not that hard to do. If you buy one brand new, they are factory set at 75 psi which is plenty unless you have a mansion. But you may want to go down there and check it out, maybe just take the whole thing out, and get a small stick of copper and 2 couplings and just take it out. It won't hurt anything, usually, the meter has a PRV so you won't have to worry about any of your fixtures blowing up.
