Capping gas appliances?

[macka09]

hi guys. When capping off an existing appliance such as a hob or oven. If the pipe work is concealed by the units do you normally cap of with compression or ef? Do you normally try to trace pipe back to tee to avoid long dead legs on the gas carcass? Purge points are being mentioned to me but if the pipe is concealed behind units surely you don’t use compression. Advice would help me out, thank you.

If you cap off with a compression are you not going to have exposed the pipes

I tend to give the customer choice regarding location of cutting and capping describing benefits of each (e.g. if capped further down then they can remove whole pipe- since it often seems to be done when they are about to have new kitchen fitted so less holes to cut into back it kitchen units).

And relation to compression that completely depends on installation going in front of it.

Solder is best if possible but if it's easily accessible afterwards (whether through a hole in back of cupboard or removable oven etc) then compression is fine as far as I'm aware.

Also gotta consider if the pipework is exposed further down the line then theirs the possibility of it being disturbed thus causing the compression fitting to leak, in which case 100% solder cap.

If it is accessible then you can use compression.
End feed is good.
Iron plugs are good.
It all depends on what you are doing.
I wouldn't worry too much about dead legs on domestic gas. If there is a chance that someone may re-install another gas appliance in the same place in the future, then I would leave it where it is.

Always solder if concealed. But in relation to your question. If the pipe is behind a unit. How are you going to cap it in the first place without making access?

The unit is coming out for a new kitchen.

Then solder

Compression in this context is DIY, IMO. If there is zero chance of point being used, then I am sure it is written somewhere that it should be cut back. But I would only bother of it was convenient, and it all adds to the Beer Scrap

But who on earth mentioned Purge points?

I always solder if possible.

Solder or press fit cap

I was by in about commercial for purging fellas. Apparently my boss thinks if there’s a dead leg it should be able to be purged?? God knows

yes commercially yes you need to put a valve and a purge point before you cap so it can be purged back to gas once the works been done and also if they want something connecting you can purge later on
