I'm planning to replace a radiator in my conservatory, which is tee'd
off the main CH circuit. Now there will some time (a few days) between
chucking the old radiator and installing the new, smaller, one.

The plan is to freeze the pipes after the tee junction, cut the pipes
and put some "cupro fit" compression stop ends over the pipe ends.
Then, when the new rad. appears re-freeze, remove the stop ends and
plumb in the pipework with straight couplers onto the open ends.

Now, about the preparation of the pipes before I cut them: they are
currently painted over. I plan to remove the paint with fine wire-wool
and use a circular pipe cutter to make the cuts. Will this ensure
a good enough fit to the compression joints, and will I be able to
just pull/twist off the stop ends when it's time to install the new
radiator? Or do I need to cut back the pipes further?

Your comments and suggestions would be welcome

Use Speed easily demountable, or better still compression stop ends.
