Pilot Light and Burner Issues in Florissant
A frequent problem with gas water heaters is a pilot light that won't stay lit or a burner that fails to ignite. This can be caused by a faulty thermocouple, a dirty pilot tube or issues with the gas control valve. Our technicians in Florissant are skilled at diagnosing these components and performing the needed repairs, whether it is cleaning, adjusting or replacing parts.

Gas Water Heater Noise Troubleshooting in Florissant
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 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.

Water Heater Tank Leaks and Pressure Issues in Florissant, 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 compromised 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 Florissant, MO home.

Frequently Asked Questions About Gas Water Heater Repair in Florissant
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 high end. We quote before starting.
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 related part.
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 indicates a potentially dangerous gas leak that requires immediate professional attention.
Watch for a lack of hot water, inconsistent water temperature, a pilot light that won't stay lit, unusual noises like rumbling or popping, a rotten egg smell, which can point to a gas leak, or visible leaks around the tank. Any of these warrant a professional inspection.
Yes, our technicians are trained and experienced in repairing all major brands of gas water heaters commonly found in Florissant, MO homes, including Rheem, Bradford White, A.O. Smith, State, Noritz and more. We carry a wide range of universal and brand-specific parts.
Most common gas water heater repairs can be completed 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.
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 licensed plumber.
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 take care of.
