gas emergency shut-off valve

[Nakajo]

I have a house with a gas emergency shut-off valve at the (external) meter but nothing at the point at which the pipe enters the property. I understand that it's good practice to provide one as soon as practically possible after the pipe enters the building - but is this a Building (and/or Gas Safety) regulation, or just a good practice recommendation?

Illustration (a) on page 80 of the hse's Safe installation guidance shows a shut-off valve at the external meter but it's unclear (to me anyway) whether an additional valve needs to be provided immediately on entering the property, or only at the appliance(s).

It depends on what kind of property it is. The rules are different for flats to houses

 

[Nakajo]

It's a house.

 

[muggles]

In that case the external ECV is sufficient, there's no requirement or need to have an internal valve

 

[Phill Peck]

Then no I don't need one
A basic explanation would be...an AECV is for blocks of flats where there meter is either not accessible or not reasonably accessible in an emergency.

A lot of gas supplies in houses will leave the meter through the wall and not reappear until it reaches the appliance.

There's a paragraph next to a symbol of a shut off valve that reads "Gas emergency control - situated as near as is reasonably practical to the point
where the pipe supplying gas enters the premises or building (see also
paragraph 2 of this appendix"

And what of Picture A of that appendix?


Situation of the OP is fine.

 

[Nakajo]

Yes, precisely my question. The illustration shows an ECV apparently adjacent an appliance but legend states that the ECV is as close as is practical to the pipe entry point. See my point?

Anyway, if you're all happy, then I'm happy.

 

[Dan Robinson]

shows an ECV apparently adjacent an appliance

No it doesn't. What does ECV stand for?

 

[Nakajo]

OK, it shows a Gas emergency control (according to the legend) but calls it an Appliance Shut-off device. ECV stands for Emergency Control Valve.

 

[Dan Robinson]

Indeed - those symbols are standard symbols for valves. Emergency or otherwise.
