hi guys,
Allow me first to say what an absolute superb website this is! The guys on here really know their stuff, as I've been an avid reader for sometime... Anyway, my first post, is unfortunately not a good one..
Over the last few days I started to notice, on and off, a very small smell of gas, coming 'only' from where the gas meter is installed. (underneath the stairs).. So, I thought I better check it out..
So, I first did some basic checks before calling out Transco.. I isolated the Vaillant Boiler, by turning it off and closing the Ball Valve underneath. The gas cooker unfortunately does not have an isolator.. Anyway, I carefully watched the Gas Meter over the next hour or so, (obviously all gas appliances off) and sure enough it was moving very very slowly, roughly '5 little notches' on the meter over the hour (the indicator furthest to the right).
SO, I called out Transco, and the guy confirmed there was a 'pinhole leak' somewhere. He said it was dropping around 3/4mm? over 2 minutes. He decided to change the meter, which was quite old, just in case.. and then proceeded to use a sniffer and some soapy water! Unfortunately the leak was still present, and he could not detect any leak around the meter. He said although the leak was not that bad (boarderline tolerances?), as I reported that I had smelt some gas, he had no other option but to capp the supply!! His conclusion was that it was most likely to be the copper piping between the meter and my boiler.
Now, the cooper pipe goes into the floor, which has been secreeded over (under floor heating), but I realise that there is no pipe lagging around the pipe where it comes up through the floor, although I denfinately do know there is lagging on the pipe under the floor. Would the secreed have caused the copper to corrode or something similiar where it touches it on the sufface? My underfloor heating and boiler are only 7 months old, and I have never smelt any gas previously, all through winter in all.
Lastly, when commissioned serveral months ago, it was pressure tested, and there was 'no drop' at all.. got a Gas Safety Cert as well, from the Corgi guy, (who is conveniently on hols till next Monday)
What's the best course of action / suggestions? Thanks all
