Hi,

Maybe some of the older people on this list can help me with this one.
Our house was built in 1970 and Im sure that some of the pipework that
I thought was 22mm or 15mm OD isnt. My questions are 1) What is the
situation when joining new metric pipe using std brass compression
fittings to the old stuff? 2) Also will the new speedfit connectors be
ok on these posssible imperial sizes?

Thanks,
Matthew

|15mm and 1/2" are almost identical. 15mm compression should work with

If you are into Yorkshire or end feed fittings adaptors are still available

Indeed, I used a soldered end feed convertor to go from 3/4 to 22mm. I
did try compression, but one wouldn't seal on a standard copper olive,
the other did on a brass one.

Cheers

Paul.

Speedfit do a connector for 1/2 inch to 15mm. Although when I used it I
found it to be a little loose (but no leaks) so I just used a standard
fitting which was a little tighter to push on but with no ill effect.

Yup. Much to my surprise, our local Wickes holds stock of 3/4" to 22mm
end-feed and solder ring fittings.

I bought two 3/4" to 22mm solder ring fittings because I thought the old
pipework here was 3/4". It turns out I was wrong - it is metric, so I
have two of them lying around here going to waste.

So if anyone's having difficultly getting hold of any, I'll bung 'em in
a jiffy bag to the first person who e-mails me their postal address.
They're of no use at all to me, and I've taken them out of the packet so
I doubt Wickes will take them back.

Things like that go into my copper plumbing bits box, because they may come
in useful sometime in the future.

True enough. My problem is that I always forget what I've got stashed
away and end up buying things several times over on the assumption that
"there's no way I've already got one of those". I found a telescopic
basin bottle trap in a cupboard the other day; I have absolutely no idea
why I'd have bought one, nor any idea of when I bought it.

I dread to think what I'll be like when I'm old(er).
