Replacing bathroom radiator valves

[Abbiel123]

Trying to change bathroom radiator valves but I can’t get the old olive/nut off… any advice?

Also the small plastic part next to the pipe, will I need to put that back in before fitting new valve? (Complete novice)

Your fecked now should of used the old nut and olive now you need to cut the pipe back and use a coupling if you haven’t any slack

You have to cut it right below the bottom of the olive

Yep will need to cut pipe under olive. Could use a short rad extension instead of pipe coupling.
