Is there a gas leak if my pilot light goes out

Is There a Gas Leak if my Pilot Light Goes Out?

A common sight on boilers across the country, a pilot light provides a permanent ignition system for the gas supplying the heat for your home or business needs. In most appliances, the pilot light remains lit 24/7. For various reasons, however, it may be extinguished. From an inefficient flame through to a faulty or dirty thermo-couple, there are several possible reasons a pilot light might fail.

When the pilot light is out, does this mean that the gas which usually powers it is escaping into the atmosphere? Although this is an area of concern for many people, the reality is that boilers are built so that the gas supply to the pilot light is shut off if the flame goes out. Whilst the cause of pilot light failure needs to be investigated, extinguished pilot lights aren’t going to cause a gas leak.

How is the gas shut off when a pilot light fails?

The gas supply is controlled through a thermo-couple, this is an electronically powered valve that’s activated by the gas flame from the pilot light. When the pilot light is lit, the heat generated creates an electrical current in the thermocouple. This provides the power needed to keep the gas supply valve open. When the pilot light fails, the source of heat is removed. This causes the valve to shut, cutting off the gas supply automatically. The use of the thermocouple provides a valuable safety feature on modern boilers, meaning there’s no immediate cause for concern should the pilot light go out.

What should I do if the pilot light goes out?

In the absence of any other boiler symptoms, we recommend attempting to relight the pilot light a couple of times. Follow the manufacturer’s instructions for how to do this. Always make sure that the gas valve is switched off and that you have allowed a few minutes for any gas present to dissipate before attempting to relight the pilot light.

Toilet flusher broke on me this morning. Communication with this company was great! Nick reached out to me first with a rough timeframe when someone would be around (same day). That someone was Gary, who first called asking for more details and I was I was able to provide photos. He gave me a more specific timeframe for his arrival, which he stuck to, and then he showed up with all the parts and tools he needed on hand, knowing exactly what needed to be done, no surprises. He was fast, professional, friendly, and cleaned up everything when he finished. Highly recommended! Cheers Gary!

We called Pinnacle Plumbing when we discovered a very serious water leak at our house, and we happily recommend them to anyone in Brunswick East and the surrounding suburbs. Despite contacting them after hours, Jay arrived within half an hour of my call and was able to quickly identify the problem, prevent it from becoming a total disaster, and tell me what needed to be done. Jay and Gary were back at 7am the next day, and within a few hours they had found the source of the leak (which was hidden underneath concrete slabs) and fixed it. They also tidied everything up beautifully. They are both lovely, and we will definitely use Pinnacle for any future problems and will recommend them to our friends. Thank you Jay and Gary!
