How to change blanking plug valve on heated towel rail?

[ade]

Hello team,

I just noticed that in one of my bathroom, the blanking plug valve on the towel rail is leaking. I just moved in this new house and the valve looks old and the seal a little damaged. Anyway, I just ordered a replacement but I have no idea on what is the process to change that. What valve should I turn off to stop the water pressure and unscrew the old valve so I can replace it?

I can share pictures if needed.

Many thanks!

Shut the radiator valves
Upon the bleed/vent plug to check they pressure drops off and the valves are holding.
Grab some old towels and swap the leaking plug.

Hey Scott, many thanks for your reply.
So, if I got that properly

1. Be sure that the radiators are cold
2. Turn off the valve of the single radiator (the left one on the attached picture I guess?)
3. Open the bleeding valve and let spill go, if the valve is holding it should stop in few moments
4. Remove the blanking plug and swap it with the new one

Am I correct?

Both valves will have to be closed.

Oh okay, great, thank you very much for that!
I'll proceed as soon as the new valve arrives 👍

The valve on the right is a lockshield. When closing, count the number of turns. Afterwards reset the valve to the same position.

I am having some difficulties on removing the myson valve you can see at the right, it only has one Center screw but is very tight. Does it needs just a bit of WD40?

Sorted, it was just very rusty, I might need to change the lock shield valve soon
