Zone Valve Replacement in Barnesville, PA
A zone valve opens when a thermostat calls for heat and closes when the room is satisfied. Each one has a small motor head and an end switch that tells the boiler to fire.
Failures come in two kinds. A valve stuck closed leaves one zone cold while the others work. A valve stuck open, or a failed end switch, keeps heating a room that never asked for it, or fires the boiler with nowhere for the water to go.
Many zone valve motors can be replaced without draining the system, since the head comes off the valve body. A body that leaks at the stem or will not seal is a bigger job and needs the loop isolated.
Reliable Boiler Service connects Barnesville, PA homeowners with technicians who test the 24-volt signal, the end switch and the valve itself before replacing anything, and who check the zone control board on houses with several zones.
