gas leak!

[ever88]

hello folks

renovating a house at the moment and suspect a gas leak with good reason but can't find where.

with pilot light out at the back boiler and the only other gas item the oven in the house switched off, the gas meter will click around a single unit over 24hrs.

to give a feeling as to how bad this leak is

if I turn a gas ring on the oven for 10 seconds this equates to the same amount. i.e. the meter clicks around by the same value.


I have disconnected and reconnected meter and the o ring at the joint did look a bit on the old side but can see a leak from joint either with a meter or leak spray and are struggling now.


I suspect that the pilot isolation could be at fault on back bolier but it works fine and cuts out when turn isolator.

any advice or ideas please?

typical that I should be getting new carpets put down very soon and will probs need them up to find leak.

begining to wonder if it was leaking all along even before I purchased.

cheers

you need to get it tested by a gas safe engineer

I would suggest you call the emergency number on the gas meter 0800 111 999 and tell them you THINK you can smell gas, they will send out an engineer to test supply and confirm whether you have a leak. This will be free. If they find a leak they will cap your meter and it will be up to you to pay your own engineer to find and fix leak.
Otherwise, call a gas safe engineer who will test your supply (this will cost you) and hopefully find and fix suspected leak in the same visit.
There are methods and certain tools that a gas engineer use's to find gas leaks that a DIYer will not have. You HAVE to have a u-gauge or manometer to confirm gas tightness/leak.

Problem is a leak could be anywhere. Isolate each appliance by shutting off its main supply valve and see if you get a lose then.

If you do, then obviously the leak is in the pipework, which by itself should have no leak at all.

But over a 24 hr period of time, it could register some drop, if the pipeworks overall temperature gradients vary from time to time over the 24hr period and cause a certain amount of gas shrinkage.

The recognised way to test for a gas leak is with manometers.

I would advise you however, that if your not competent to do so or it is not your own home, don't test it yourself, its against the law, even though the tests are very easy to do.

And as somebody has already said, it does need specialists tools such as manometers to measure the drop and possibly a gas leak detector would be handy.

And get it checked as soon as possible right now even. Just call Transco its free and the number should be on the meter or in the phone book.

What!!!, get a gas safe registerd engineer out asap!

Otherwise it wont just be the carpets being pulled up youll be worring about!

Seriously, listen to what they are saying. Call an expert. Get it checked, and do it now. Even a small leak can quickly accumilate into a potentially explosive situation.

Call an engineer, or the supplier. For good measure I would turn off the supply at the ECV - next to the meter.

put your tools down go out side and phone the national grid/British gas.
what your day job ?

why ? doesnt the national grid carry electricity and is british gas his utility supplier?

national grid round these parts for gas escapes

One possibility....

It could be the fsd on the gas valve not closing properly when u blow the pilot out.

Don't do it on ur own but mate, get someone in who is compotent/qualified with gas. This ain't a diy jobber
