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.
