Hey all,

Have been prepping floor for new carpet and punctured an unknown pipe through the side.
Looks metallic inside, does anyone know what is it?

We have just moved in so have no good idea

It about 3 cm in diameter, it is uneven and it bends at almost 90 degrees and turns into one of the bedrooms

mantles
Thanks for the reply, the house is from 1935, and the pipe feels very heavy (as in lead) indeed.

Its on the first floor so must by disused by now?

If it is lead you should be able to shave a bit of easily with a sharp knife leaving a clean shiny surface underneath.

I can't help but wonder, if it is lead, why is it across the joists? isn't that idea a bit too modern? I have seen gas lights and the pipes were in the walls, as in they were installed when being built, doesnt look quite the same for those pipes, and are they not a bit too clean?

I wondered if they are passivated mild steel pipes. The Gas Board had a cheap installation package for central heating in the 60's that used PMS pipe instead of copper. It was a disaster and it got dumped in due course. I wonder if this is redundant central heating pipe that was left there?

It's an old water pipe. The old gas pipes were cast iron. Strip it out and take it to the scrappys :thumbright:

There were old lead of "compo" pipes used for gas but not to be expected in 1930 I would have thought except for meter connections.
Wonder if it is from the early 70's during the Rhodesia crises copper was hard to get and lots of (largely unsuccessful) alternatives were marketed and used for heating installations. Being a pair flow and return springs to mind.
Maybe microbore.
