gas leak head scratch!!

[mylesy]

anyone else had this?? done a tightness test. there is a small drop. isolate appliences and when i get to the boiler and isolate it, it stops dropping. so iv found the culprite. open the valve again just to see it drop again for confirmation and its all ok???? probably re-greased itself or something, but it makes you paranoid then!! haha

so leak is on boiler

 

[mylesy]

it was, then when i reopened the valve there was no leak anymore? crazy! did it a few times just to check but nothin. wierd! iv had it before with an ECV letting by. i turned the ECV on then off again and no more let by.

best way to be , accidents can happen when we get complacent

only posible if pipes are still hot , never do tt when pipes are hot !

Had this before too. Pain gas leaks are, I hate them when you can't fine the little bleeders!

I've had it where the pilot hadn't shut off properly on a boiler. Whenisolatedit sorted itself.

thats pretty obvious, but not only possible if pipes are hot. theres quite a few situations this can happen. slight tear in monometer tube at the end, then when you push it on past the tear it stops. (this would obviously get noticed eventually and rectified) or like mike jackson says with a pilot. even tempremental solanoids. etc etc

I was gonna ask if the boiler has a pilot light. Its the only thing I can think of which could explain what you experienced.

Carried out a tt round a customers house prior to starting work, they had a big drop. I rechecked the boiler was off and asked the customer about other appliances, after isolating the gas fire / hob/boiler and checking the meter. I was getting set for capping the supply, the customer remembered she had a second combi upstairs in a cupboard.

no but iv seen gas escape through the actual valve around the slot of the isolator before. i think i re-greased it when i turned it.

had quite a few like this on the old baxi three-way taps - almost seemed a bit prone to it. maybe it was the heat etc where they were, all that expansion and contraction, plus drying the grease out I guess.
