Hi All,
I’m about to start a bathroom refurbishment and over time I have purchased most of the fittings required.
As I’ve just discovered by home has 3/4” copper pipes installed and I made the mistake of purchasing 22mm compression fitting for this job which I can’t return.
My question is can the fitting or pipe be modified to overcome this mismatch and still make a reliable long term solution .
Thanks,

you can buy a 22-3/4 that will allow you change to 22 for the rest
also use a little or similar under and around the olive, not on the threads as is commonly and erroneously done
dont over tighten
