Pressure Regulating Valve Replacement

Pressure Regulating valves keep the water in your home at a safe level. Unregulated water can cause faucets, and other plumbing fixtures to break down prematurely. Municipal supply pressure in parts of the Kansas City metro runs well above what residential fixtures are built for, and the PRV at your service entrance is the single component standing between that pressure and every cartridge, washer, supply hose and appliance valve in the house.

PRVs are wear items — most last somewhere between ten and fifteen years, and they fail gradually enough that homeowners adapt to the symptoms instead of reporting them. Watch for banging pipes when a faucet shuts off, a toilet fill valve that hisses or won't stop, faucets that keep dripping after a rebuild, a relief valve on the water heater that weeps, or a shower that hits noticeably harder than it used to. Any one of those is worth a pressure test.

Testing is quick: we put a gauge on an exterior spigot or laundry connection, read the static pressure, then check whether it climbs when nothing is running — which points to a closed system with no working expansion control. Anything much above sixty to eighty PSI is shortening the life of everything it touches. We replace the valve with a properly sized regulator, set it to a safe target, add or verify a thermal expansion tank where the system requires one, and leave you with the actual before-and-after numbers.
