Any difference between a main stopcock for a house and those in the
sheds described as "central heating stopcocks" ?

TIA

[T[ Possibly, depending on the actual tap.

I think there a 3 common tpes of inline 'tap'.

1) The real 'stopcock' with a rubber washer seal that has several
turns between on and off and really turns off (when new anyway g).
Has a T- bar type handle.

2) A ball (isolator) valve, a ball with a hole through it in a nylon
seat that can be turned through 90 deg with a screwdriver (or little
handle like on a washing machine one).

3) A gate valve where a slightly tapered metal plate is wound into a
tapered slot (turns like a real tap) and typically has a round red
handle) but often leaks if you try to use it as a real tap.

All the best ..

These from B&Q are with the bar handle and compression joints. But the
packs they are in are marked "central heating". The main stopcock in
the house is oozing a little water and I want to replace it. The
body of this one has a more barreled look.

Is there any reason why "plumbers" run pipes so close together you can
hardly work on them?

Francis

just change the top bit, don't bother with the main body.

You should be able to just change the screw in body of the stopcock with the
same bit from new one.
I'd get one from plumbers merchant or jewson not B&Q.
Of course you will have to turn off the house supply in the road or get the
water company to do it.

Yes, they are idiots who don't think ahead to when maintainance has to be
done..

Do you mean, water is dribbling out of the valve around the stem, i.e. the
round rod (turned by the "handle") which goes into the valve? Water appearing
where this goes into a hex-threaded component? Try tightening up this "nut"; if
it is an old-style valve, the nut is squashing some sort of "string" against
the rotating part. It's called a gland. Crude, simple, effective. Provided the
pressure between the "string" and the stem is more than the water pressure then
the water doesn't get out.

Thank you (and the other respondents) this has cured the problem :-))

Because customers complain if they spread piping out all over the
place. There's also an element of professional pride in keeping it as
neat and tidy as possible.

And then billing £££ the next time they're called out as it takes them twice
as long to do the work as access is difficult.

It'll never catch on as an idea though
