Gas tightness test

[David Sarbutts]

Hi, do gas engineers do a gas tightness test when you have your boiler serviced to check for gas leaks?

Some do, some don't. It's not a specific requirement.

Hi Muggles, I had my gas and electric smart replaced today and upgraded. When the engineer did a tightness test on the gas it failed and he said there was a leak. I had my boiler serviced 2 weeks ago and everything was good and I wondered why this wasn't picked up on the service. I called British gas homecare cover and there engineer found the leak. I just wondered why the tightness test wasn't done on the service for safety. If I hadn't had the smart meter changed today, I wonder if the leak would have been found.

Hi David,

It’s not a requirement to carry out a tightness test (TT) for servicing an appliance as it can be isolated at the appliance and just leak detection fluid applied afterwards to any disturbed joints. It’s good that the meter exchange has found it for safety and that is a requirement of their job because the pressure would have been lost during the exchange.

was not done because it is not a requirement during a service

Hi gas112, the leak was found on the compression elbow in the loft which connects the pipe to the boiler. The compression nut was loose.

did he say how much the drop was on it ?

 

[David Sarbutts]

No he didn't say.

I had it done a few years ago by my usual boiler engineer If I remember right he was explaining that there is an allowable drop over a certain time frame

I was with the engineer when he found the leak, but we couldn't understand how the nut had become loose. We had to part the pipe next to it so the engineer so he could get his adjustable and grips to tighten it as it was in a tight space.

My guess is that it was never done up in the first place

 

[David Sarbutts]

I think your right, due to the awkwardness.
I've lived in this property for 4yrs and it must have been leaking, however, our gas bill wasn't high.

 

[gas112]

No he didn't say.

should be on the warning label he left you

 

[David Sarbutts]

Nothing on the label and nothing on his warning notice, only that it had failed it's tightness test.
