Guess the pipe (found in my garden)

How old is the house and do you have any downpipes in that area?
It looks about the correct size for an old cast iron pipe possibly heading into a drain or soakaway.

Look, lets quit the guessing game OP, you need to expose it up to the house and find out what it is, not difficult it's under slabs not concrete;)

Should have asked earlier, out of curiosity, what Dia is it?

I’d go old gas pipe seen plenty like it?
If you have a decentish continuity tester you should be able to use that one prong on exposed pipe other just before gas meter on pipe as it comes from ground but its not 100% accurate

It might not help in your particular situation but if they are fitting a new plastic gas pipe then do they run it 'inside' the old one?

I am sure they did something like this in my parents road last year although I might be completely off track! I didn;t watch them do it but they replaced the gas pipe to everybody's house in the road without digging up the path and simply dug a hole in the pavement where the joint was - maybe they replaced the whole thing and took out the old one which would be quite impressive through a 2foot square hole and without digging up a 10m long driveway.

I had the old lead water pipe bypassed 20 years back when I moved to this house.
30mtrs from the road to the entry point, 4 holes 600mm square and a good mole sorted it.

But get this, the guy charged me £40 including pushing the pipe through after the mole, :T:T:T(I bought the pipe), Today. £400????

In reply to the last post the last thing the OP wants is another pipe up the 1 that's in the way??

My point was that this pipe might already contain a plastic gas pipe - not that he should have one installed.

It could affect the results of any audio tests already suggested.

No they don't push a new plastic gas pipe in an existing metal one , because it would be impossible, I mean, how would they do a t-junction. They put in new yellow plastic pipe at the correct depth and just leave the old pipe, it's not worth their time taking out.

I took a load of old 2 inch gas pipe out of my garden, all dead but when I cracked them open there was still a heart-stopping couple of seconds as all the old gas came out.

Well,. They certainly did that when replacing a gas main outside my house a couple of years ago.

Yes they do - at street level they use the old cast pipes as a sleeve for the new plastic pipe.

At every existing tee to supply houses the cast pipe is smashed out so the individual house supplies can be plastic welded to the new street supply once it has been fed through and then connected to the existing individual house supply, rarely will they supply new plastic all the way to the property.

There's plenty of ways to skin a cat, this is one of them that I've seen in action
