How can a gas leak be found? (Ed.)

[Molly67]

Cadent came out last night and detected a gas leak under the floor boards In my water tank cupboard and gave me a reading of 180pm capped the gas and told me to call liberty this morning liberty came out and couldn’t detect a leak to which cadent came out again and they also couldn’t find a leak now? Anyone any advice on what could have triggered the probe to give an indication of the gas leak in the first place? I’ve got 3 kids and not sure if I should be worried or not

Silly question - but Im guessing Liberty turned the gas back on, when they checked for a leak?

Yes they did and also did a tightening test

What was the result of the drop test?

What was the result of the drop test?

cadent said there wasn’t a drop in pressure from the start, I initially called cadent because my house mainly the bedroom with the water tank stunk of fuel/ petrol type smell which they put down to someone flushing petrol or cleaning something petrol related and it going into the drainage but then they detected a gas leak I’m now wondering if the smell of fuel could of triggered the gas detector

someone flushing petrol or cleaning something petrol related

Someone? In your house?

Some years ago we had a smell of gas in the downstairs entrance hall where there is a cloakroom and the external gas meter is on the outside wall of the cloakroom.
We called out the appropriate people and they tested around the outside meter and inside the hallway, all the tests were negative. The guy said they had been called out to about half a dozen houses within 500 yards of us, all showing a negative result.
He (rightly or wrongly, we don't know) put it down to gases, possibly partly methane being pushed up through the sewers after heavy rain.

It's never happened in the 10 or more years since.
