Gas Control Valve Replacement in Alton, IL
The gas control valve regulates temperature and shuts off gas if the pilot goes out. Newer valves from Honeywell and White-Rodgers use status lights that blink codes when something goes wrong. If the valve itself has failed, we replace it with an exact match or approved universal model. We leak test and confirm temperature control afterward.

Pilot Light Repair in Alton
A pilot that will not light or will not stay lit is the most frequent gas water heater call. Causes include a worn thermocouple, a clogged pilot orifice, a bad piezo igniter or a tripped thermal cutoff. We test the thermocouple output with a meter and service or replace the pilot assembly. Most pilot repairs are finished in about an hour.

Water Heater Tank Leaks and Pressure Issues in Alton, IL
While gas water heaters are robust, tank leaks or pressure problems can occur. We can often fix small fitting leaks or replace relief valves if pressure is too high.
