Dripping radiator pipe?

Pc88

Hi,

I’m preparing a bedroom for plaster by wallpaper stripping and had to remove the radiator. With the radiator off, I’ve noticed both radiator pipes are very slightly dripping despite both valves being closed (turned clockwise).

Is this normal? The concern is that I’m going to be away from the house for a few days so wanted to know the best course of action to take. Shall I stick some kitchen roll in the pipe? Put radiator back on but have it laying down? Turn mains water off via stopcock?

I’m new so can’t post link to an image so just remove the space between https and :

Get the right size version of this. Either half inch or 3/4 inch. Screw them on and itll make it watertight. Good practice in case valves get knocked etc too.

If it is a closed/pressurised system, turning off the mains will do no good. I suppose you could drain the system of some water, to lower the system pressure, if the bedroom is upstairs. Best option is as suggested by jrrowleyws

Drain the system and change the valves, they need changed anyway, you would be better doing it now.

Just so I'm clear, when you say replace the valve, I'm assuming we're talking about this unit?

Ah, cool, Didn't know those existed, thanks. I'll get those caps in the meantime to save me from emptying bowls from time to time.

Definitely go for this option, everything else is tempting fate. You will also want to either ptfe the rad valve thread or fit a flat rubber washing inside the end of the cap.

They come with a rubber washer. Good point though, make sure it is there!!
