Friend is looking for a gas valve controlled by a gas detector.
Something like this he thinks:
but he wants a mains powered version for domestic use.
I haven't had a chance to speak to him but I suspect it is to prevent his mother, who is becoming increasingly senile, from gassing herself. She has a gas stove without any flame failure detection.
TIA

That doesn't actually say whether it's mains or 12V, but you could soon run it from a 12V PSU.
They should be a reasonably common item in most merchants, I doin't know anyone who's mentioned trouble sourcing one when we've fitted them.
Thanks Stuart
After posing the question I was musing on the possibilities open to him.
I agree with your point about running it from 12V.
Presumably any gas control valve for a boiler would also be suitable? He could drive that from any gas detector and alarm suitable for Natural Gas. I doubt if the marine alarm would be designed to detect NG.
What about installation? Presumably if he did it himself - installing it in the stove supply only - any CORGI bod visitig to service either the boiler or the stove would have a fit and cut off the house supply?

As long as the valve was suited for the gas supply at the property then there'd be no reason to cut the supply off.
Looks good On a slightly different slant - nicking copper gas pipe has become a good way of raising 50p and I wonder if any method exists to shut off a gas supply if the flow exceeds a 'normal' flow.
Some flats being built near me have suffered the 5th theft of pipes running up the exterior wall next to a main (Ring) road. Fortunately they are not occupied yet - but hey! I can nick a bit of pipe and be away before I get a sniff. The newspaper will say £1,000 of damage - that will encourage others
That's a standard (and I presume, required) feature of french gas isolation valves.
Have we finally found something good to say about French plumbing?

Personally I would buy her a new cooker with Flame failure, while she can still learn about FFD.
Have you contacted the manufacturer? Most 12 V things are modifications of a 240V device.
Couldn't agree more. Unfortunatley when the oven 'stat died earlier this year rather than seize the opportunity to replace the stove with a modern unit he spent more than the cost of replacement on finding both 'stat and someone who knew how to fit it. Stupid berk is reaping the rewards of that particular act of folly.
As to learning anything new: she is so ill as to probably require incaceration but what remains of the NHS is unwilling/unable to accomodate her.

Yes this has become a big problem. Last year I started losing lengths from the pipe carrier. So now I have added a lock (my pipe carrier was a 110mm soil stack home made version). A couple of Transco guys were saying that they've been to a number of gas escapes due to people removing pipes.
Perhaps people will stop running copper around the outsides of buildings. It always looks rather horrible to me.

My Dad was called out to an emergency 'breakdown' one day and got there to find water cascading through the ceilings. Further inspection found that the loft mounted boiler had been crowbarred off the wall.
Update on the gas valve question:
Andy doesn't need to connect it to a gas detector, it merely needs to be operated by electricery. The idea is to fit the valve where his mother cannot see it and then hide the operating switch in a cupboard.
Does that make identifying a suitable valve any simpler.
BTW the stove is connected to the gas via a bayonet fitting and he wonders about interposing his electric valve between hose and bayonet outlet.

So would a tap not be suitable?
Not really, same valve, just operated by a switch rather than a switch attached to a detector.
I woiuldn't. Is he going to attempt to fit this valve himself?
Hi Stuart
It's difficult to convey how pig headed Andy can be in a brief email!
I asked him why a tap or even a tap with a padlock would not do the job, i.e. 'KISS', but he says that he doesn't want to upset his mother - go figure!
However, in his defence, having seen his mother a few times in the last year and listened to a few of the phone calls that he has answered from her, I don't think I could cope as well as he does with caring for someone with S.D. Memorably she complained (on the phone) a few months back of the house being too hot - when he returned Andy found that the room stat was set to maximum and that she had been attempting to adjust the temperature by adjusting the pointer on a circular barometer. Hilarious but distressing for Andy. The last time he managed to get a break, rather than arrange respite care, he made his brother stay to look after her so that Keith would understand just how dreadful things are.
I very much fear that he does intend fitting whatever abomination he cobbles together himself. I may post a warning message to the NG as to when you should avoid his particular bit of Sarf Lunnon.

My mate suffered twice little "shites" using the external gas pipe as a handy hand/foot hold to climb over his side gate. First time pipe broke away leaking gas, 2nd time pipe bent. Pipe was finally moved indoors.
