Is it something to do with girls and big bottoms? Should they, shouldn't they?

It's a tightness test at th appliance. Put your manometer on the inlet and shu off the gas to the appliance. Then do your test on the appliance only.

The older posts were talking about gas valves letting by and doing a mini tightness test. What is it just for curiositys sake?

Anything like this shouldnt be spoke about to public. Prove to dave or one of the admins that your GSR to get into the private parts ... Of the forum that is .... Eee 1 of those days ...

its a safety check what your talking about basically what you said its to make sure that gas is not passing after the safety device, thermocouple for instance has clicked and shut the valve

have you got a link to the thread

its how you "confirm" a thermo electric valve is shutting off, i wish i had £1 for every re-assessment candidate who describes the procedure as "listen for the click, then you know its shut" one of the few things that drive me mental during ACS

Kirk if the valve dosent shut off does this mean the valve needs replacing?

9/10 a valve passing gas will be caused by dirt on the seating from impurities in the gas, similar to a dripping tap needing a new washer, but like a tap sometimes the face is worn and it wont seal, or in gas if it has a spring it could break, the problem isnt actually repairing is making a gas tight seal at the valve when done, im sure in the good old days the gas guy would have stripped cleaned and refitted in jig time, but nowadays we would renew the valve

Hmm! I have as I recall repaired a gas valve before. But what a job, you have to go very careful how you strip it down or the parts fly all over the place. Get an old one and have a go you can learn a lot, they are fiddly though, its probably worth replacing with a new one rather than attempting a repair for a customer and of course a new one usually has a guarantee with it.

we get the trainees to strip old valves down to see whats happening inside them, and over a period of time there seems to be less and less components in them as springs fly everywhere
