Doing the kitchen this break and after stripping wall paper I was tidying up and could hear a buzzing sound, first thoughts were of an insect caught in the paper on the floor but after clearing up could still hear it.
What had happened was that water from stripping the paper had dropped onto the gas pipe that led to my cooker and a small leak was causing the water to bubble creating the buzzing sound!
How lucky was that? It is a very small leak at the site of a connection and could have been leaking for a long time but you cannot tell, anyway, gas off at meter for now.
Query, do I call British Gas or a local engineer? Probably covered on house insurance but need to check.
If one leaking there may be a possibility that there are others leaking also.
I know British gas can do a leak test at the meter to find out if there is still gas leaking when that fault has been repaired.I would imagine the Local engineer would be able to do the same but may not have the proper equipment with him.
Ask the Local engineer if he can also do the leek test at the meter just to be in the safe side.
AitchBEE - An annual gas service/safety check is essential. People can die from carbon monoxide poisoning. As lotvic says no-one should be in that situation.
Blackhat - A Gas safety local engineer is what I would use. One with personal recommendations and not purely from the gas safe site. He or she will have the right equipment to check for any other leaks.
Checking for gas leaks on pipe joints (they usually occur at compression joints) is a relatively easy process. Get an empty liquid soap bottle and put an inch of washing up liquid into it. Then add an inch of water and shake gently.
Squirt a little of the resulting mixture onto the suspect joint and watch - you'll see large bubbles forming and bursting if there's a leak.
