Taking radiator off

Post by pvr » Mon Nov 06, 2017 5:06 pm

Part of a room re-decorating, Mrs PVR has decided that the radiator needs to come off.

Any tips - or just replace the thermostatic valve with a fixed one and close the rad valves, then undo the two bolts? How to avoid getting the black water everywhere might be a useful tip ... :D

Wall mounted radiator by the way.

In the past I've slacked the joints by the valves and swung them flat to the floor supported on blocks of wood then retightened the joints - only works if you have a bit of slack in the pipes so you can lift it off the brackets (you say bolts so do you have the traditional cast column type so not much lifting). Not saying its the correct way mind.

I've also found those 'radiator rollers' are a good tool for papering as well as painting the wall behind.

One reason I hate thermostatic valves - aren't you are going to have to freeze the pipe to change the valve though if you want to change it?

PS the above won't work on curved rads!

If you have a TRV, there should be a cap that comes with it. This is meant to hold down the valve seat when the TRV head is removed. You can then remove the rad. In practice, these caps are rubbish and you end up with leaks anyway.

Also, do you have drains on the radiator itself? Otherwise you may need to drain the system down completely or at least to a level where the water isn't going to come out. Not a good time of year to be doing this too..... :D

I meant nuts - not bolts actually. They are the 90 degrees jobs out of the floor, into the rad.

I would be quite happy for the decorator to paint behind the radiator using a small brush, apparently that is not the correct way to do it so I have been told :cry:

Screw the TRV fully down Paul. Lock off the other side using a small adjustable spanner on the small valve shut off lug. This will stop the flow to the rad. Loosen the bleed valve on the top of the rad. Then you can undo one side of the valves a little, having a washing up bowel and old towels under the thread, undo it until you’re happy with the flow, it’ll take time but be patient, better to take a while than have it rushing out. Once empty undo the other side and lift off SQUARELY, don’t tip it, maybe have a couple of blocks of wood ready to put it on if it’s a big heavy rad. Once off you can tip it gently until it’s completely empty. If the valves are tight DON’T force them until you’ve got an adjustable holding the valve body steady or you could rupture the copper pipe.

so much easier and the finish will be identical.
Why is it that people who can't take advice always insist on giving it?

Yep, this is easily the best way to get around the job and with a 20% vat busting your wallet re-payment on a huge £2.49 investment if bought in B&Q on the Isle of Man, you cannot ignore this tool Paul.

Tell the missus if she wants the rad off to take the bugger off herself..... :P

Be careful if your TRV Has a frost setting, the trv will open up at around 4 degrees C.

I’d advise getting a couple of female irons, short section of copper and some 15mm compression caps. I don’t remove many where the valves hold 100% so always use caps.

It only takes a drop of ‘Black Death’ and the carpets ruined.

All done now and no carpet was ruined :D

Straightened the radiator as well whilst it was off as it was mounted poorly with just two screws on the slider bars and no screws in the small hole to retain it, so it was a bit lob sided.

I hate doing plumbing stuff though ...
