Dripping radiator valve

[scottpetrie]

Hi
Im in the middle of decorating my hallway, and when I was removing old skirting board from behind radiator I must have knocked it. Now its dripping slightly at the valve. Tried nipping it up but still getting the odd drip. Could it be the olive had come offseat and needs replacing?

very doubtfull, probably just needs a proper man tighten

What part of the valve is it leaking from and what pipe diameter?

 

[scottpetrie]

Its a lockshield valve. Looks like its coming up through the threads of the nut from the pipe coming up through the floor. 19mm

 

[ianmcd]

wont be 19mm will be 22mm or 15 mm post a pic so we can advise you

 

[scottpetrie]

Slowly seeping up through these threads. Yes, sorry its 15mm

 

[ianmcd]

Yes its 15mm hold the valve body with grips and tighten the nut up will be fine

As above, get some decent spanners on it and give it a 1/4 turn. It is leaking between valve body and the olive. If that fails to fix it, you will need to drain down and apply a smear of sealant either side of the olive faces.
