Signs and symptoms of a faulty gas regulator
Yellow or orange flames
If the flames from your gas appliances burn yellow or orange instead of the normal blue, it likely indicates a problem with the gas regulator. This is caused by incomplete combustion of the gas due to low pressure or reduced oxygen. The sooty, yellow flames are a warning sign to get your regulator inspected.
Soot buildup on burners
Excess soot or carbon accumulation on gas stove burners or other appliances is another red flag for regulator issues. Soot buildup is a byproduct of incomplete combustion, again signalling improper gas pressure or flow.
Whistling or hissing sounds
Hissing, whistling or other odd sounds coming from your gas appliances can signify a faulty regulator. This may indicate gas is leaking past seals or other components. Strange sounds always warrant immediate investigation for safety.
Pilot lights repeatedly go out
If the pilot light on your water heater, furnace or other gas appliances keeps going out, a faulty regulator could be to blame. Inconsistent gas flow and pressure from a malfunctioning regulator can cause pilot lights to extinguish.
Appliances not igniting or irregular flames
Problems with ignition or uneven, irregular flames can also indicate regulator issues.
Appliances may fail to ignite or only partially light. Appliances may fail to ignite or only partially light. Appliances may fail to ignite or only partially light.
Testing your gas regulator
The first step in testing your gas regulator is a simple visual inspection. Turn off the gas supply and detach the regulator from the gas cylinder or supply line. Look for any signs of damage, rust, or corrosion on the regulator body and connectors. Examine the flexible pigtail and inlet strainer for kinks or obstructions. Also check for loose parts or missing screws. Any visible issues with fit, form, or function are red flags that require replacement.
Soap test for leaksNext, perform a leak test using a spray bottle with soapy water. Reattach the regulator and open the gas valve momentarily to pressurise the line. Spray the regulator seals, inlet and outlet fittings, and all connecting joints. Observe carefully for any bubbles, which signal gas leaks. If leaks are detected, turn off the gas immediately and replace the faulty regulator. Never attempt repairs on a leaking gas component.

Resetting or replacing your faulty gas regulator
Resetting your gas regulator
Resetting your faulty gas regulator may resolve issues if the problem is not mechanical. Follow these steps to safely reset a regulator:
- Turn off the gas supply and detach the regulator.
- Use a small flathead screwdriver to press down on the reset button, if your regulator has one.
- If there’s no reset button, turn the adjustment screw counterclockwise to reduce pressure.
- Reattach the regulator and slowly turn on the gas supply.
- Light the pilot lights and turn on appliances to check flame quality.
- Use a pressure gauge to adjust regulator output to the appliance specifications.
Replacing your gas regulator
If resetting doesn’t solve the issue, replacement is required. Follow these safety steps:
- Turn off gas and detach the old regulator.
- Apply pipe joint compound to regulator inlet and outlet threads.
- Attach new regulator with proper orientation, using wrenches to tighten.
- Perform a soap test to check for leaks.
- Slowly turn on gas and test appliance pilot lights.
- Consult appliance manuals for proper gas pressure.
- Adjust regulator to achieve the correct outlet pressure.
- Continue monitoring appliance performance.
Gas regulator replacement requires proper tools like pipe wrenches, Teflon tape, a pressure gauge and leak detection solution. Follow instructions precisely to ensure safety. Consult a professional plumber if unsure.
When to call a professional
While some basic gas regulator troubleshooting can be safely done at home, there are certain situations that unequivocally require professional assistance for your safety.
Gas leaks detected
If a leak test reveals bubbling around regulator fittings or connections, immediately turn off the gas and call a professional plumber. Never attempt to operate appliances with known gas leaks, as this can lead to fire or explosion.
Major damage or corrosion
Significant visible damage like cracked fittings or corroded parts means the regulator should be replaced by a certified gas fitter. Attempting to repair severely damaged regulators risks gas leakage.
Improper flame appearance
Yellow, orange, or irregular burner flames even after resetting the regulator indicate a need for professional replacement. Improper combustion can generate dangerous carbon monoxide.
Inability to reset or relight pilot
If the regulator reset procedure and relighting appliance pilots fails to fix combustion issues, professional help is required. Forced operation of faulty equipment may compound problems.
Lack of experience with gas systems
If you lack knowledge and experience with regulators and gas systems, do not attempt repairs. Mistakes made through guesswork with gas equipment can have disastrous outcomes.
When in doubt, call the experts
If you have any doubts about the integrity of your gas regulator or ability to safely service it, immediately call qualified plumbers like North Ryde Plumbing. Our experienced gas fitters can accurately diagnose regulator faults and undertake replacement to manufacturer’s specifications.
Gas regulator safety and maintenance
For routine gas regulator testing and maintenance, the unit must be readily accessible. For routine gas regulator testing and maintenance, the unit must be readily accessible. Make sure the regulator remains visible and can be reached quickly in an emergency. Do not cover or obstruct regulators with clutter or decor.
Allow ample working room around regulators during appliance servicing. Shut off valves, pressure gauges, piping, and inlet/outlet fittings should have space for inspections, leak checks, pressure adjustments, and potential replacement.
Also ensure regulators are mounted properly to remain stable when attaching hoses, gauges, or other fittings during testing. Position wall-mounted regulators at a comfortable height for visibility and access. Proper accessibility facilitates regular regulator and appliance safety checks.
