Leaking tower radiator

[Stockdale9189]

Hi all,

I am new to plumbing so please bear with me

I have a small leak at the top of my towel heater as shown on the picture attached.

I presume I need to re-seal the leaking valve or change it, but how should I go about doing this?

The leak only happens when the central heating cools down, not when it is on.

Thanks!

Thats just a blanking plug, screwfix sell replacements in pairs, bleed and blanking plug. Shutoff both radiator valves, opdn the bleed screw and let as much water out as you can, have some towels handy and remove the p!ug and replace, you mayhave to dig out remains of the old washer, I always wrap the threads with ptfe.

You'll need to rebleed afterwards.

Ah. So once I have replaced the plug, what do I do? Repressure my central heating, re-open the radiator valves and rebleed? Or rebleed before reopening the valves?

Re open valves ,bleed air and top up pressure if need be.
