Removing a radiator for plastering

[Armo74]

No,One or the other. If you are leaving the trv head on in the closed position you will need the end cap as a back up just incase the trv opens slightly due to the temperature change in the room. If you are removing the trv head you can place a coin on the pin that opens and closes the valve and tape it on, wont hurt to stick the end cap on again just as a backup.

So if I do it the coin way don't you have to put anything over the threads either end incase water comes through?

Sorry i showed you the wrong cap end in the last pic.

you want one of these to screw on the trv end.

with a 1/2" rubber washer seal.

Cheers for the cap pic, Does that go on where the thermostat is or does it go on the left on the thermostat, where the tread is?

 

[seco services]

That go's on where you disconnect from the radiator.

 

[tellytv]

So if i put the cap around the thread

Can I still remove the thermostat use a 5p coin to push the pin down then put the thermostat back on to be safe?

That part stays in the rad you'll be disconnecting the next nut along.
but yes same idea.

 

[tellytv]

So I can do it both ways to be safe?

Also is it possible to put a cap on the lockshield valve side, is it possible from water to come from that side aswell?
