Gas Control Valve Replacement in Sunnyvale, CA
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 listed universal model. We leak test and verify temperature control afterward.

Propane Water Heater Repair in Sunnyvale
Rural properties often run water heaters on propane rather than natural gas. Propane units use different orifices and regulator pressures, and improper conversions cause sooting and poor performance. We confirm the correct parts are installed and repair pilots, valves and burners. We also check tank regulators for correct pressure.
Emergency Gas Water Heater Repair in Sunnyvale
When your gas water heater suddenly stops working, especially on a busy morning, it is an emergency. FBL Plumbing offers prompt emergency repair services for gas water heaters in Sunnyvale. We prioritize urgent calls to get your hot water back quickly, knowing that a lack of hot water is more than just an inconvenience.
Power Vent Water Heater Repair in Sunnyvale
Power vent heaters use a blower to push exhaust out through PVC pipe. Failures often involve the blower motor, pressure switch, hot surface igniter or condensate in the vent. We read the error codes, test each part and repair the failure. Correct vent slope and termination are verified before we leave.
Venting and Draft Repair in Sunnyvale, CA
Atmospheric gas water heaters depend on a properly sloped metal flue to carry exhaust out of the home. Disconnected sections, rusted draft hoods and poor slope can let combustion gases spill back. We repair or replace vent sections and verify draft with a test. Proper venting is essential for your family's safety.
Gas Valve and Thermostat Repair in Sunnyvale, CA
Issues with the gas valve or thermostat can lead to inconsistent water temperatures or a complete lack of hot water. Our team can test these key components for proper operation, checking for electrical continuity and gas flow. If a part is defective, we will replace it with a quality, manufacturer-approved component so your water heater heats evenly and safely.
Gas Water Heater Noise Troubleshooting in Sunnyvale
Odd noises coming from your gas water heater, such as rumbling, popping or whistling, often indicate sediment buildup in the tank or a burner problem. Hard water can add to sediment accumulation. Our repair service includes flushing the tank and inspecting for sediment, addressing pressure issues or checking other components that might be causing the noise, improving efficiency and quiet operation.

Tank Leaks & Pressure Problems in Sunnyvale
Even gas water heaters can develop tank leaks, often due to corrosion from hard water or high water pressure. Water hardness in Northern California varies a lot by source, with snowmelt-fed systems running soft and many inland groundwater systems running mineral-heavy. While some leaks might require a replacement, minor leaks or pressure relief valve issues can often be repaired. Our team checks the extent of the damage, inspects the anode rod and addresses pressure imbalances to prevent further complications in your Sunnyvale home.

Frequently Asked Questions About Gas Water Heater Repair in Sunnyvale
The cost of gas water heater repair in Sunnyvale, CA can range from $150 to $800, depending on the scope of the issue and the parts required. Minor repairs like a thermocouple replacement might be on the lower end, while a gas control valve replacement could be higher. We provide a detailed estimate after finding the problem.
Following the label instructions to relight a pilot is generally safe. If the pilot will not stay lit, or you smell gas, stop and call a licensed plumber.
In most cases, minor repairs like replacing a thermocouple or a thermostat do not require a permit. If the repair involves major changes to the gas line or venting system, or if the unit needs to be replaced, a permit from the Sunnyvale building department might be necessary. We handle all necessary permitting.
On average, a well-maintained gas water heater can last 10 to 12 years. Regular maintenance, including flushing the tank, can help extend its lifespan. If your unit is nearing this age and having frequent issues, replacement might be more sensible than continuous repairs.
Replacing a part like a thermocouple or gas valve typically does not. Replacing the water heater or altering gas piping or venting often requires a permit, which we handle.
Our technicians are experienced in repairing all major gas water heater brands, including among others Rheem, Bradford White, A.O. Smith, State and Noritz. We have access to parts for a wide range of models and manufacturers.
Most common gas water heater repairs can be finished within 1 to 3 hours. More complex issues, or cases where special parts need to be ordered, could extend the timeline. We strive for efficiency without compromising safety or quality.
