Flammable Vapor Sensor Repair in Wentzville
Most gas water heaters built in recent decades have a flammable vapor ignition resistant design. A sensor or flame arrestor screen shuts the burner down if it detects vapors or overheating. Lint and dust in garages can clog the arrestor and trip the system. We clean the combustion chamber and replace sensors or thermal switches as required.

Water Heater Tank Leaks and Pressure Issues in Wentzville, MO
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. If the tank itself is failing due to rust or old age, a replacement might be the more economical long-term solution. We give you an honest assessment of the repair options for your Wentzville, MO home.
Gas Control Valve Replacement in Wentzville, MO
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 fails. If the valve itself has failed, we replace it with an exact match or approved universal model. We leak test and verify temperature control afterward.
Commercial Gas Water Heater Repair in Wentzville, MO
Businesses in Wentzville, MO depend on a constant supply of hot water for their operations. Our team is equipped to handle the larger, more complex gas water heater systems found in commercial settings. We understand the need for limited downtime and provide efficient, durable repairs to keep your business running smoothly.
Venting and Draft Repair in Wentzville, MO
Atmospheric gas water heaters rely 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 confirm draft with a test. Proper venting is critical for your family's safety.

Gas Valve and Thermostat Repair in Wentzville, MO
Issues with the gas valve or thermostat can lead to inconsistent water temperatures or a complete lack of hot water.

Gas Water Heater Noise Troubleshooting in Wentzville
Strange 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 speed up 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.

Frequently Asked Questions About Gas Water Heater Repair in Wentzville
Most gas water heater repairs cost $150 to $700. Thermocouple and pilot work is at the low end, while gas control valves and power vent components are at the higher end. We quote before any work begins.
Generally, 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 Wentzville building department might be necessary. We handle all required permitting.
Gas tank water heaters usually last 8 to 12 years. Hard water sediment and skipped maintenance can shorten that.
Many Honeywell and White-Rodgers valves use flash codes to report problems like a weak thermopile or a tripped sensor. We read the code and test the matching part.
We repair Rheem, Ruud, A.O. Smith, State, Bradford White, American Standard and Whirlpool gas tanks, among others. We stock common pilot and valve parts.
If you smell gas, leave your home right away, do not turn any lights or appliances on or off, and call your gas company's emergency line and then FGV Plumbing from a safe location. This points to a potentially dangerous gas leak that requires immediate professional attention.
Following the label instructions to relight a pilot is usually safe. If the pilot will not stay lit, or you smell gas, stop and call a professional.
Because of the dangers that come with natural gas and possible carbon monoxide poisoning, gas water heater repairs should always be handled by a licensed professional. DIY attempts can be dangerous and may void warranties or violate local Wentzville, MO plumbing codes.
