Default Compression fittings

IIRC the old 1/2" copper pipe is so close to 15mm that new fittings will go
onto old pipes, but I'm not sure about the old 3/4" copper.

Will a 22mm compression fit or do I need an adaptor?

Dave, you are correct for 15mm, but 22mm - 3/4" needs an adaptor.
mind you iirc 1/2" is a tight squeeze.

You need an adaptor for soldered, or for compression, get some 22mm-3/4
olives.
These can be used in normal 22mm compression fittings, but are fatter at
one end to allow 3/4 pipe to be sealed well in the larger 22mm fitting.
Only available at decent plumber merchants, 50p each iirc, which seems a
lot for an olive, but remarkably cheap compared to a proper 22 to 3/4
compression fitting.

Cheers for the tip Alan, I've got a proper plumbers place nearby.

Ideally, as others have mentioned, a 3/4" olive. But you can get away with
murdering up a soft copper 22mm olive onto 3/4" pipe, might not be so
successful with a hard brass 2mm olive.

Go to a real merchant and ask for a "green" olive.Substitute this for
the one in your 22mm fitting.Cost pennies.

By a real merchant, do you mean one that stocks tartan paint, sky hooks &
long weights?

Ok,smarty,come back with the smart answers when you actually know
something about the subject.
A green olive is the industry standard way of joining 3/4" copper to
22mm with a 22mm fitting.Has been available since metric pipe first
appeared.
Is painted green so muppets like your self know what it is.

I'd assumed that you were winding me up. e.g. trying to get me to go to a
local plumbing shop & ask for a 'green olive' as in fruit.

The term 'green olive' may well be a regional term relevant to the area you
live in. A Google search for 'green olive' gives 1.5 million results, the
first 4 pages deal only with restaurants & recipies. No mention of a
plumbing application.

I was in my local plumbing merchants today, they supplied 2 suitable
olives - which were certainly not painted green at all. They are a goldy
colour distinctly different from other olives I have seen. I asked if these
were called 'green olives' and they clearly had no idea what I was on about.

It may be the 'industry standard' where you live. They may be called
'green' olives where you live. They may be painted green where you live.

None of which seems to apply in the south east of England. If you enter
'green olives' into the Screwfix search engine you get a page of safety
trainers.

If I misunderstood you and incorrectly assumed it was a wind up or a joke,
then I appologise.

Given this question has come up several times on here during the many
many years I've been reading this group, it's the first I've heard of this
expression. And since I was around when the conversion happened and bought
such things then something painted green would have stuck in the mind. Nor
does painting an olive sound like good practice to me - they rely on
intimate contact to seal properly.

Perhaps it's a regional thing like 'pattress'.

Just had a look in my plumbing bits in the shed. Two large olives. One
has a slightly larger taper on one side and has a slight green tint.
These are from 1988 when I redid the kitchen and bathroom in my last
house and had to connect old imperial to new metric pipework
