pipe 1, is capped off. i think it might be water as it is cold to

stop cock inside the coal hole as well, and from there on the pipes
are not lead in the whole house.


A lead gas pipe would be equally cold to the touch. It used to be
common pratice for water pipes to be fed through the basement of
several properties in a row. The capped off pipe might be the old feed
on to the property next door.


by looking at the picture and the way that pipe was capped off, is it
possible to say if it is/was water or gas, or both services' pipes are
capped off in the same way?

Now I can see the picture ;-)

The gas pipe (2) appears to be a recently installed one. Looking at the
photo, it appears to have an unsealed hole around it where it comes
through the wall. It appears it might be a modern steel pipe served
with hemp?

I would expect the capped pipe if a water pipe, to look quite similar
to the other water pipe and come through at a similar height to it.

For the above reasons I would therefore suggest it is probably the old
gas pipe and will likely have been cut off at the other end as well. I
would guess that there is no gas in it, that it was simply sealed until
the old gas main was cut off. I would suggest the new pipe was put in
round about the time your home was converted from coal gas to higher
pressure natural gas.

That is just my guess based upon what I can see and interpret from the
photo. Ring Transco up and ask them to confirm my guess and that the
pipe can be safely removed.
