Drainage dripping...

[Stephen19]

Hello again, just to say that I have a rad that has a very very slow drip from the drainage pipe. As I'm not a plumber I am not sure what its really called but I have seen plumbers use this with a bit of hose to drain the rad before removal. Hence I call it the drainage pipe!
It drips really slowly when rads are working, does not drip when cold. Have tightened a little, as far as I dare go and no change. Without wishing to run up a big bill I wonder if I could bung the whole with a small bespoke cork or similar? Highly unlikely I will ever need to use the pipe and if I leave a cork end exposed it could be taken out again with pliers or whatever (if really needed). Any advise on this action please?
thanks
Stephen

Any advice on this cork solution welcome...and it drips when cold as well now !

just change the rubber seal in the draincock or you will have a big bill the day you need to use it and you've blocked the hole.

Ah ha, its a draincock!
Thanks Seco. I guess this involves sealing off each end and draining through this draincock first?
