[CAESAR32]

Di most people air test gas pipes to 0.5 bar before tapeing and or concealing covered pipe work.

I doubt any one will give you an answer, as it appears to read like DIY Gas work.

Well im.a plumber gas engineer I work with doesnt. But I no from my viper book. Studying nvq level 3 that you should.

Ask him why he doesn't

 

[CAESAR32]

He says he trusts his soldered joints

Exactly what I thought he'd say... As do I mine! Final tightness test will be the make or break and his name is on it, so it's in his corner really.

Is this a homework question then?

Really yes, I wonderd if he was one of few that didn't air test or if it was the norm. Is the reasoning behind it as once the joints taped it may disguise a leak on the final tightness test?

yes that is exactly why, you must test the pipe and joints before painting wrapping or any other protection as the protection could mask a leak. Stick in lad and I hope the trade treats you well

Thanks and 0.5 bar for 2 minutes is the required air test? I think I would test though I am confident in my soldered joints. Its not like performing an air test is a time consuming processes.

Stop trolling a forum. DIY advice unless qualified isn't allowed.

Get yourself to the CC if you need but you won't get anything in here.

YOU ARE QUALIFIED TO TEST NOTHING. IT ISN'T YOUR JOB SO LEAVE IT.

My amatuer soldering is good enough for 10 bar air distribution - doesn't mean it's good enough to pass a drop test.

I know just wanting to learn more as I don't totally agree with some of the stuff the gas engineer I work with does. Is a shame I have to wait to qualified to learn from the usefully contributors to this forum?
