Hi everyone,
I was suspended today pending an investigation and disciplinary hearing after a 4mb gas leak was detected on a joint i had soldered over 7 weeks ago when fitting a gas meter in someones living room.
On my first tightness test before the installation I recorded a drop of between 0.25 and 0.5 mb. After the installation I carried out three tightness tests whilst I waited for the pipe to cool and recorded 0.5, 0.25 and then 0mb on the last test. I also covered every joint and pipe I had touched with LDF and found no bubbles.
A colleague of mine attended the job to fix the leak and advised me he recorded a drop of 4mb and that LDF produced bubbles straight away on the joint but that it was not under stress, nor was it a fluxed unsoldered joint which had crossed my mind.
Can anyone give me advice about what they think might have happened after I left other than foul play by customer, the joint cracking under strain or the pipe being accidentally knocked by someone after I had gone?
Also, does anyone know if a tightness test can hold when it's not tight other than for a pinched tube or unsoldered fluxed joint?
And lastly, does it seem right that a 4mb leak in a living room would go undetected for 7 weeks?
Thanks for taking the time to read this, if anyone can offer any advice/suggestions I'd be very grateful!
