Zone Valve Replacement in San Antonio, TX

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 San Antonio, TX 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.

Call Reliable Boiler Service at (866) 456-6311 for zone valve replacement.

Zone Valve Replacement FAQs

Frequently asked questions about Zone Valve Replacement

Questions we hear most often about Zone Valve Replacement in San Antonio, TX.

Talk to a real person
What pressure should my boiler run at in San Antonio, TX?
Most residential hot water boilers sit around 12 to 15 psi when cold and stay under 30 psi when hot. Steam boilers are different and run at a fraction of a pound.
Should I repair or replace my boiler?
Repair makes sense for parts like igniters, circulators and zone valves. A cracked section, a leaking heat exchanger or a boiler where parts are no longer made usually points to replacement.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
What does a lockout code on my boiler mean?
The boiler tried to light several times and failed, so it shut itself off for safety. Note the code before resetting, since it narrows the cause down to ignition, flame sensing, venting or water pressure.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
