I am fitting 22mm compression stop end to a cold water pipe in my
bathroom and was wondering how far onto the pipe should the
compression ring go? Many thanks.

Depends on the fitting.
The olive goes wherever the fitting needs it.

The olive ( ring ) should slip onto the pipe and be able to slide back
and
forth reasonably freely.

Then slide the fitting onto the pipe till it bottoms out.

Then slide the olive back against the fitting, and do up the nut.

Thanks Ron. Don't think i cleaned the end of the pip enough then, as
the olive doesn't slip that easy.

Would a pushfit or speedfit fitting be better. I've just had one fail
but it was from B&Q. It lasted 6 months so not sure why it went pop
today perhaps local water authority increasd the pressure again.




If the pipe is deformed such that the olive can't be slid to it's correct
place, then I'd cut back a little further or clean up the pipe or whatever
it takes .

Pushfit fittings also need clean, in-gauge pipe to work properly.

You really need to get the pipe sorted.
