Default imperial/metric

are 1/2" to 15m/m and 3/4" to 22m/m copper pipe adapters available, I have
tried B&Q warehouse and Wickes without any luck.

1/2" and 15mm pipes are so similar that you can use 15mm compression or
solder fittings on 1/2" pipe without any problems.

22mm pipe is *slightly* bigger than 3/4". You can use 22mm compression
fittings on 3/4" pipe with special olives - with a slightly smaller ID. You
can get these at a decent PM but maybe not at the sheds.

If you want to use solder fittings to join 22mm and 3/4" pipe, you need
special fittings whose two ends are a slightly different size. Again, you
can get them from a PM - or probably on-line from the likes of BES.

Or if needs must, run a pipe cutter round a 22mm fitting once or
twice... not enough to cut into it, but enough to put a dent into the
circumferance and reduce the diameter enough to solder it! (DAMHIK)

Compression yes, but I have experienced the odd failure when using 13mm
fittings on 12.7mm (1/2") pipe.

Indeed - if SSq had left off "without any problems" then OK. I have found it
necessary on many occasions to abrade (with steel wool) 1/2" pipe down quite
a lot to get 15mm solder fittings on. They will go eventually though. If
they are too tight a fit then the solder won't flow properly and the joint
will be suspect for ever more so it's worth working them to an easy fit.

I'm not sure which pipes you are talking about. Half inch pipe isn't 12.7mm.
The 'half-inch' refers to the nominal bore, so that the OD is larger than
this - and very close to that of 15mm (not 13mm) pipe.

Yorkshire and other soldered fittings *no*.
There used it be special soldered fittings but I doubt they sell them any
more.
Always use compression fittings to join imperial to metric.

Too harsh, they (15mm fitting onto 1/2" pipe that is) will go with a bit of
effort and quite successfully. Most of my radiators are fitted like this
(1/2" installarion converted to 15mm then onto rad).

There used it be special soldered fittings but I doubt they sell them any
more.


Yes I bought some not long ago, you can still get them I believe. The 22mm
to 3/4" ones are easier to find (as you can't do without) but you can still
get the small ones, I believe.

Easier but not better (but that's not an imperial metric thing!)

Last time I tried, I found end feed 1/2 - 15mm and 3/4 - 22mm adaptors at
my local PM.

Yes sorry, I'm in pratt mode.

I have had failures when using 15mm couplings on older 1/2" pipe. I now only
use new pipe for everything and have had no failures at all.

SWMBO bought a mixer tap from Ebay. Nice bit of kit. Then you notice French
markings for Froid et Chaud. Ne problem, mais. . .

Apparently the French go in for 12mm couplings and flexible hoses the size
of a pencil. I managed to get some adapters from Plumb Centre and it is all
OK apart from the hot flow, which is slower than I would like.

www.bes.co.uk sell end feed 15mm to 1/2" for 21p or solder ring for £1.50
odd. Also 3/4" to 22mm as well. Last one I got from Jayhard (when they
existed) a couple of years ago and when I found I was one short on a Sunday,
from Homebase of all places for a rip of cost.
