What does a gas leak smell like and what should I do?

Natural gas and LPG are dosed with a sulphur-like rotten egg odour so you can smell a leak even at low concentrations. If you smell gas: don't switch any lights or appliances on or off, don't use phones inside, turn off the gas at the meter if safe, open doors and windows, leave the property, and call us from outside on 1300 677 752.

Are you licensed to do gas work in NSW?

Yes. Gas work in NSW is restricted to plumbers holding a current gas-fitting licence. Mr Splash Plumbing operates under NSW plumbing licence #306457C and is fully insured for all gas detection, repair and installation work.

How do you find a gas leak you can't see?

Licensed gas fitters use electronic gas detectors, pressure-decay testing on the gas line, and soapy-water bubble tests at joints to pinpoint the leak. We isolate the affected section, repair to AS5601 standard, then pressure-test the line before reinstating gas.

Can a small gas leak really be dangerous?

Yes. Gas accumulates in enclosed spaces and only needs a small spark to ignite. Even slow leaks can cause headaches, nausea or carbon monoxide exposure when appliances burn incompletely. Any suspected leak is treated as an emergency.

Do you handle the gas connection for a new appliance install?

Yes. Licensed gas fitters at Mr Splash Plumbing install and commission new cooktops, ovens, gas heaters and continuous-flow gas hot water units, plus issue the Compliance Certificate required by the gas supplier. Quoted upfront with fixed pricing before work starts.

What should I do if I smell gas?

Turn off gas at the meter, open windows, do not use electrical switches or flames, evacuate the property and call your gas provider or 000 in an emergency.

How do plumbers detect gas leaks?

Signs of a Gas Leak in Your Home

As we mentioned earlier, finding out whether you have a gas leak is easy.

Natural gas in an unaltered state doesn’t have any odour. A pungent gas by the name of mercaptan is added to natural gas to give it that distinctive odour. That allows the user to easily detect any gas leak. So, the moment you start smelling the odour, you need to act. The longer you ignore a gas leak, the more hazardous it is.

What to Do If You Smell Gas

When you smell the odour of gas, don’t panic call Mr Splash Plumbing on 1300677752.

The first thing you need to do is to extinguish any live flame and shut down your appliances.

After that, you should immediately try to close the gas main pipe to disconnect the gas from your home. It’s always a good idea to know where the closing valve is.

After you’ve closed the valve, open all the doors and windows to let the gas out.

Be sure to inform everyone who’s present on the property about the gas leak. After all, you don’t want to accidentally cause a fire.

Once you’ve taken all these steps, immediately give us a call.

It might also be a good idea to stay away from indoors for a while. Perhaps, you could wait in your backyard until our gas leak detection experts arrived on your property. Inhaling the gas isn’t good for your health and there’s always a risk of fire.
