Checking gas fittings for leaks is important for home safety. Mix soapy water and apply to joints and connections. Bubbles indicate a gas leak. Turn gas off immediately and ventilate the area. Call a professional gas plumber to inspect and repair leaks.
Having gas appliances in your Mosman home provides comfort and convenience, but gas leaks can also lead to dangerous outcomes. As your trusted local Mosman plumber, I want to provide some guidance around detecting and preventing hazardous gas leaks.
It’s crucial that all gas lines and appliances are thoroughly inspected for leaks on a regular basis. Even small leaks over time can cause health issues or lead to fires and explosions. My team at Mosman Plumbing has the expertise to assist with all gas fitting inspections, repairs and installations.
In this article I’ll cover the tell-tale signs of a gas leak to look out for, the dangers leaks pose, tips on prevention, and when to call in the professionals. Having the right knowledge keeps your family safe and avoids costly damages down the track.
There are a few key warning signs that indicate a potential gas leak in your home or business:
Gas leaks are hazardous and need immediate attention. If you notice any of these warning signs, evacuate the area, avoid using anything that may spark ignition, and call a professional plumber straight away.
A visual inspection of your gas appliances, fittings, metres and regulators can also identify leaks. Look closely at joints and connections for any discolouration on pipes, which may indicate corrosion and potential leaks. Examine the pipes leading into and out of your gas metre for concerning discolouration as well.
Check gas appliances like stoves, ovens, heaters and hot water systems thoroughly.
Look for any discoloured metal joints or fittings, damaged or corroded pipes, or scorch/burn marks in unusual places. Watch the flame colours and patterns - they should burn evenly with a blue colour with no yellow tipping. Yellow flames, wavering flames, flames coming out of non-burner parts or the appliance failing to ignite can all signal a gas leak.
Also inspect the rubber gas line leading into each appliance. Cracking or deterioration can cause gas to escape. Having a comprehensive understanding of what your gas appliances look like in proper working order makes it easier to notice when something is amiss.
If you spot any of these visual warnings, turn off the gas at the mains and contact a licenced gas fitter to inspect, repair and pressure test. Never delay when it comes to gas leaks.
One of the most reliable ways to detect a natural gas leak is to use your nose. Natural gas distributors add a chemical called mercaptan that gives gas a strong, unpleasant rotten egg odour so that leaks can be more easily sniffed out.
If you ever notice even a faint rotten egg smell in or around your home or business, evacuate immediately and call the fire department and a professional plumber. Don’t try turning appliances on or off or operating any electrical switches. Any spark could ignite the gas and cause an explosion.
Conduct periodic 'sniff tests’ around gas appliances and pipe connections to be alert for leaks before they become large or hazardous. Trust your nose - if you ever detect a sulphurous rotten egg scent, assume there is a dangerous leak until proven otherwise.
the rotten egg smell, listening for sounds can also alert you to a potential gas leak. Escaping gas often causes a distinct hissing or high-pitched whistling sound.
Be attentive when operating valves on gas appliances, regulators, and metres. If you hear hissing near connections or pipes as gas escapes, it indicates an immediate leak. The loudness of the sound typically correlates to the size of the leak.
Small leaks may produce faint hissing, while larger, more hazardous leaks result in louder whistling. If you detect any hissing or whistling around gas fittings, turn off the main gas supply line and make an urgent call to the gas company and a professional plumber.
Conduct periodic leak checks by turning appliances on and off, and listening closely for any unusual sounds which signal gas escape. Trust your ears - unexplained hissing or whistling sounds demand further inspection from a qualified technician.
One of the most effective DIY methods for checking gas fittings and pipes for leaks is conducting a soapy water test.
You’ll need a spray bottle, pipe brushes, rags, a wrench to turn off valves, and dish soap and water.
Make sure to shut off gas valves before starting. Mix the dish soap with water until sudsy. Then spray or brush soapy water liberally on pipes, joints, valves and appliances.
Watch for growing bubbles, which indicate escaping gas. Concentrate on joints and connections.
Compare areas to differentiate between normal moisture bubbling and actual gas leaks. If any leak is detected, wipe the area clean and immediately shut off main gas valves. Compare areas to differentiate between normal moisture bubbling and actual gas leaks.
Repeat this test regularly, such as yearly or after earthquakes, to detect potential leaks early. Turn valves on and off during tests for a thorough inspection. Trust your eyes during the soapy bubble test - any leaks evident should be addressed promptly by qualified technicians for your safety.
Specialised gas leak detection tools provide another means of identifying and confirming leaks.
An electronic gas detector can pinpoint even tiny, dangerous leaks that you may not be able to see, hear or smell. Professional plumbers use quality electronic methane detectors and ultrasonic detectors to conduct thorough gas leak inspections.
Portable gas detectors help professionals locate the exact position of gas leaks quickly. They can then diagnose problems and determine if repairs, replacements or other solutions are required.
For ongoing peace of mind, homeowners could also invest in a natural gas alarm or methane detector for additional monitoring between professional checks.
You could likewise install carbon monoxide detectors as a precaution. While CO is odourless, a detector can alert you to its presence if faulty gas appliances are leaking.
Gas leak detectors are not usually DIY devices - the most effective monitoring comes from detectors used by qualified technicians. If your professional inspector confirms a leak with detectors, address it urgently.
