capping off a gas fitting.

[dobbslc]

I need to remove this old cooker hose from the gas fitting. It's been there over 45 years!

It looks about 3/4", what do I need to do this?

 

[Maker]

Qualifications I'd imagine.

 

[123hotchef]

take the hose off and get a 3/4" cap if it is as you say 3/4" some fernox or ptfe screw it down check for leaks and jobs done

 

[Screwdriver]

You need a registered gas safe engineer.

 

[angellonewolf]

as @Screwdriver said gas safe person or you risk your home if something goes wrong

years ago you could do it had a bloke fitting propane used to just cheak for leaks with soapy water round all joints

but if you call a gas safe is a 10 min job prob 30/40 pounds and you still have insurance if some thing happens

a half inch bsp iron bung and gas thread tape or paste job done just check for leaks . that's if its your own property and for your self .for anyone else just shove ithttp://www.irrigationonline.co.uk/black-iron-steel-bung/

 

[dobbslc]

Maybe I phrased the question badly, I know how to do it but don't know the right terminology to buy the end cap Eg 3/4" bsp/Whitworth/unc/hammer a cork in it!
The cooker is coming out on Saturday and I'm not getting the plumber round till the old gas fires come out and the new boiler goes in. The gas is shut off anyway so I don't invalidate the unoccupied house insurance terms.....

 

[FoxZulu]

DO NOT touch it. As said above, get a qualified gas engineer in.

Your problem is that without any gas you can't prove you've not left a leak

If the end of that hose is attached to nothing then the line is already open. If you need the hose out the way to decorate then remove it and use a vibrant coloured tape to close the end off and stop debris entering the already breached line.

Don't fit a plug because you can't test that you haven't left a teensy wee leak that you won't initially smell but it will build up and that will not be cool.

You need a GS person to recomission the line using a drop test on a manonmeter (or whatever the modern equivalent is that I just aged myself by naming that tool lol).

Must be old if it doesn't have a bayonet fitting (i.e. push up and twist...)

I'm always amused by Gas Safe who are holier than thou about gas and how if you look at it the wrong way - boom you'll kill everything within 100 miles, YET they often have no electrical knowledge, nor capability to do it properly or safely yet quite happily "have a go" or tell joe public (with even less knowledge or confidence) that its fine to do it themselves.....the amount of times I've seen CPCs in flexes used as line conductors by Gas Safe guys is....ridiculous....(and thats just the mild end of things...)

My son has just bought a house to rent, so required cert for gas. The guy who did it didn't even do a leak down test. How is that passable but a cert was written out.

 

[FoxZulu]

Being 'holier than thou' I must advise that leaving an open gas pipe is an offence, not to mention potentially very dangerous. On the other hand, DIY electrickery, what could possibly go wrong?

 

[WorkshopChris]

So (honest question) in what way is it dangerous is the gas supply is currently capped off (usually whats required for unoccupied homes) there is no gas going through the pipework and the open end is known, I'd also argue that there is a duty of care on the part of the competent person aka Gas Safe to check that there are no open fittings / lines BEFORE reconnecting / recommissioning the gas supply akin to an electrician being REQUIRED to check that the circuit and installation is SAFE and fit for service BEFORE re-energising the supply - saying "it should be fine" doesn't cut the mustard, its generally referred to as gross negligence / incompetence and failure to exercise proper duty of care, which as an independently certified and certified competent person you wouldn't have a leg to stand on should you recommission the gas supply without doing proper checks beforehand albeit IANAL

Any service must be left in a condition that would be safe if re energised unless the Valve or Isolator is physically locked off.

First thing you do before working on a system is check for leaks. Otherwise you have a job on making the customer pay for an existing problem. Also stops you checking your work over and over again.

Also obce ypu have worked on a system, you have 'adopted' it, so any problems in the future could be blamed on you

You need a 1/2" bsp plug and a dab of jointing paste. Unscrew the brass cooker flex connector from the m&f elbow and screw in the plug. Brass or iron will be fine test with weak soapy water solution and then rinse off if you want to be fussy trust me I only did it for 42 years.

couldn't be simpler dunno why theres allways a fuss

 

[Kayos]

Can't leave an open end because the supply could be restored by someone unaware of the need to test.

Immediately dangerous and RIDDOR reportable if found

 

[Kayos]

Fair enough point,
BUT IF the system works then the only person who should be turning the gas supply back on should be gas safe and if they turn it on without doing the tests then they aren't competent.....
Otherwise its an implicit admission that people without certs are regularly doing gas work / a sizeable minority of gas fitters are doing the "bang test" instead of proper testing

I don't know the exact wording, but being the first person to allow gas to enter a property (or reinstate supply) is a specific procedure and not following it means hell fire and brimstone will rain down upon you, I think

 

[dobbslc]

It's done now, all capped off and no smells.
The house is stripped almost bare with nobody to live there now

 

[brightspark]

did u do it yourself or pay an exorbitant rate and get someone to do it for u
