Hi,

I had transco out today to check an old gas pipe that was sticking out of the bedroom floor. He confirmed it was dead and said I can cut it off so we can lay carpets.

He said I can cut it to floor level and then fill it with some expanding foam to stop insects getting inside etc.Can anyone recommend the tools for this job and give any other tips?

What would be the best cutters to get it cut as close to floor level as possible? Hacksaw or pipe-cutter tool or something else?
What type of foam would be suitable to use?

Any advice greatly appreciated!

Thank you.

If you can lift up floor & remove as much of the old pipe has poss then seal with a soldered cap, never know some time in the future someone could reconnect to this pipe
 
Lifting up the floorboards will not be an easy job. If the Transco /national grid say its OK then I reckon i'm safe right?
 
If the pipe can be pulled up by an inch or two then pull it up and grip it ( with mole grips maybe ) in the raised position. Then cut as close as possible to the floor. The when you release it it should fall below the floor level.

That depends on how he decided it was "out of service". Did he find the other end ? And if so was that end visibly disconnected from any source of gas ? If not then I would agree with a soldered on cap..

No he didnt locate the other end (would involve lifting up floorboards) - but his advice was to cut off and fill with foam!

That is not an acceptable way of sealing a gas pipe, must have a proper cap end, if under floor must be a soldered one, how do you know that pipe is completely dead , remember its your house that's at risk and not doing it correctly could invalidate your insurance. Want to know rules for sealing gas pipes then ring this number 0800 408 5577 Gas Safe technical
 
Thanks Smithy - I called them and they confirmed it should be capped off properly below floor level. I'm a bit suprised that the national grid would advise me to take the other option....

Anyone got a ballpark estimate for a gas safe engineer to do the work properly?

Again call GS they will give you numbers of engineers close to you, no idea what cost would be in London down here no more than £50. people think that just because NG do something its ok, quite a lot of times its not. As with most things get 2 or 3 prices
 
Is it possible to get the floor board up ? It's going to be a lot cheaper for a RGI to cap a pipe that's exposed, his time lifting boards will be @ the same rate as his gas work. In fact if you find someone and send them a picture on your phone even better.
 
As Nigel F ^ mentioned get the floor up,better still when the pipe is exposed take a few photos it still could be diyable :idea:

Would never advise doing DIY on gas pipe ! even if they think it's disconnected, could finish up putting a compression fitting under floor, or even a push fit, Get a Gas Safe guy in to do it then test to confirm no leaks, Customer can save money by exposing pipe.
