Better glasses these days?
No one can tell a 0.25mb drop on a water gauge with that degree of accuracy so they now say if you see it move at all then that is a perceptible movement.

That would be a rule change that would make sense for once

Sorry, but if you have passed your CCN1 you HAVE heard of permissible drop, you may have forgotten but you did answer questions on it on your theory
Kirk, what is your opinion on the question I raised at the end of post #62 albeit with the wrong figures. If I had a drop on an electronic gauge of 0.2mb but the customer could small gas (unlikely I guess) would you cap or would you class as no perceptible movement?....
I,ll take your word for it, I'm not known for my memory.

That's easy peasy, ANY smell of gas means there is a leak, if its less than perceptible movement then the leak could be on the other side of the reg which has locked up,
If its a theoretical question I would say its very unlikely to smell gas that's less than 0.2mb over 2 mins, but its straight forward by the statement that they smell it so there is something to be rectified
This leads to another question scenario:
As you have said, they smell gas but there is no movement on the u gauge, what is the procedure you MUST carry out

Haha, could be part of a procedure
Just to throw one out there,
On a cloudy day you bring your manometer to 20mb, it sunny and rises 2mb, the cloud comes over and drops 3mb, or you raise your manometer to 20mb whilst it is cloudy, it drops 2 mb, then the sun comes out and raises it by 3mb??
Do you define that a leak or not??

If there is no movement on the gauge then there may be a leak upstream of the ECV or coming from an adjacent property. The only correct course of action is to call the gas transporters emergency number and report an uncontrolled leak.

I do all my testing in scotland, what is this thing "sunny" you speak of?
K
kirkgas
Correct,
But when asked, a lot of re-assessment guys say they test the install and if there is no leak found they tell the customer they don't know what they are smelling as it isn't gas :-o
