At wits end homeowner here that needs advise. TIA. My house was built in 1999 when all municipal water meters and PRVs were installed in the meter pit between the house and the street and owned by the municipality. With much development expansion and fire hydrants the supply pressure increased. My when my outside meter pit PRV failed it sent 150psi water pressure into my house (oh what fun).

The PRV is on the municipal side of the water meter (not outlet after isolation valve) and the municipality says it is now my responsibility. And even if I begrudgingly accept that, no plumber (I have called 50+) will work in the pit on the municipal side of the meter because of liability issues (unless I absorb them). Two weeks I kept my water off unless using but still no answers. I am disabled so yes water in my home is a safety issue. I did finally install a PRV inside my home (with money I don't have) to get water back on inside my house, but now I have a new PRV in line but after a failed PRV outside my home.

Questions:
1. Obviously the outside PRV failed open to full municipal supply line Pressure. However is the failed outside PRV likely just to remain open or could it possibly close at some future date and I end up back where I started? Never a good idea to leave a failed valve in the system.
2. Anyone have this issue and know how I can get the defective PRV removed, if not replaced? No one can remove it or replace it without first removing the meter, which I don't own, to get to it.

i would guess that there are many,many thousands of failed PRVs that the owners don't even suspect something is wrong.
don't worry about it.
