Gas Control Adjustments
Essential for controlling gas flow to the burner, the gas control valve is one of the components in a gas water heater most importantly. This valve guarantees that, under safe and effective operation, the water heater keeps the right temperature.
The gas control valve may wear, misalign, or malfunction with time, which would cause unsafe running conditions, ineffective heating, and more expensive energy costs. Unchecked, a faulty gas control valve can cause uneven water temperatures, ignition problems, and possibly gas leaks.
Our area of expertise at ASAP Heater & Plumbing is gas control modifications, so making sure your water heater runs as it should while preserving safety and economy.
Indices of Need for Replacement or Adjustment in Your Gas Control Valve:
Range of performance problems can result from a malfunctioning gas control valve. These are some typical warning indicators suggesting it could be time for a replacement or modification in gas control.
- Inconsistent Water Temperature: A malfunctioning or improperly adjusted gas valve could be the reason your water swings between too hot and too cold.
- Water Either Too Hot or Too Cold: Should the thermostat settings differ from the actual water temperature, the valve could not be operating as it should.
- Frequent outages of your pilot light could be the result of a faulty thermocouple or gas control valve.
- Delayed or No Burner Ignition: Gas may not be flowing at the right rate if the burner fails to ignite or takes too long to turn on.
- Unusual Gas Smell: Should you detect gas near your water heater, either a gas leak or malfunctioning gas control valve may be the cause.
- A misadjusted or broken gas control valve might cause the system to run more gas than required, therefore raising your monthly expenditures.
- Hissing Sounds from the Valve: Should you hear a hiss sound close to the gas valve, this could point to a pressure or leak problem.
Should you observe any of these warning indicators, you should immediately arrange for a professional gas control valve inspection.
Our Gas Control Adjustment & Repair Process
At ASAP Heater & Plumbing, we use a comprehensive process to inspect, adjust, and repair your gas control valve for maximum safety and efficiency.
Full System Inspection
Before installing an expansion tank, we test your home’s water pressure and plumbing system. This helps us determine:
- We examine the gas control valve for wear, corrosion, or damage.
- We test the thermostat settings and burner ignition to check for irregularities.
- We inspect gas connections and pressure levels to ensure safe operation.

Gas Pressure & Flow Testing
- We use specialized tools to measure gas flow and pressure levels.
- If the pressure is too high or too low, we adjust the gas valve settings accordingly.
- We check for proper combustion efficiency to optimize heating performance.
We ensure that the expansion tank we install is properly matched to your system’s needs.

Thermostat Calibration & Adjustment
Once the right tank is selected, we:
- If the water heater isn’t maintaining the right temperature, we recalibrate the thermostat to match the desired setting.
- We ensure that thetemperature remains stable without overheating or wasting energy.

Pilot Light & Burner Testing
After installation, we:
- We relight and test the pilot light to ensure proper flame strength.
- We inspect the burner assembly and ignition system, making adjustments if needed.
Once everything is properly installed and tested, we provide you with maintenance tips to keep your expansion tank in great condition.

Gas Leak & Safety Check
After installation, we:
- We perform a gas leak test to ensure there are no leaks from the valve or gas connections.
- We verify that the pressure relief valve (PRV) and exhaust venting system are functioning correctly.
If we detect a major issue, we may recommend a gas control valve replacement for safety and efficiency.

When Should You Repair or Replace Your Gas Control Valve?
Not all gas valve issues require a full replacement—sometimes an adjustment or minor repair is enough to restore proper function.
When to Repair the Gas Control Valve
- If the thermostat is misadjusted but the valve is still functional.
- If the pilot light occasionally goes out, but relights normally.
- If gas flow needs a minor adjustment, but no major leaks are present.
When to Replace the Gas Control Valve
- If the gas control valve is leaking or producing a strong gas odor.
- If the thermostat no longer maintains a consistent temperature.
- If the pilot light will not stay lit, even after thermocouple replacement.
- If the valve is corroded, cracked, or damaged beyond repair.
