Swapping out a radiator

[jaguar49]

Hello,

I want to swap out a radiator as the old one is looking old and rusty its downstairs.

I may have to cut one of the pipes as I am having trouble finding a direct replacement.

If I cut the pipe do I have to drain the boiler ? As the heating is off I would of thought the water would just sit in the pipe or is it a case of the upstairs would empty out through this cut pipe.

Thanks

Drain down required before cutting into pipework.
If it is only the width between pipes/ valves that's a problem you could consider using valve tail extensions.

Thanks Terry,

Will look into valve tail extensions !!

Shut all other radiators down at both ends and then all you'll need to do is drain the pipework until it stops running. Minimises the water lost.

Depending on how old the boiler is you may be able to shut the boiler valves without them leaking but they invariably they will leak.
