hi guys been to help a freind out 2day with his shower wat it is is the valve on the cold feed has a slight drip on it i tried nicking it up 4 him but it still drips he said he had trouble fitting the valve after the tiler he employed didnt leave the correct space for the pipes so got tiler bk to file a few mm of the tile and he managed to squeeze the valve on the leak is coming from the back of the nut that sits against the wall (exposed shower valve ) so with trouble hes had fitting the valve on i dont really want to undo it is there any external sealant that will cure it as it is just a tiny drip.had water connected to the shower for 4 hrs 2day while helping him decorate and there was only a few drips in all that time thanx 4 any replys
Check the rubber or fibre washer is in place, quite common for the fibre washers to split when trying to get nut lined up with the shower valve.
The best (correct) way is to remove the shower, replace the washers and that should sort it.
Trying to stop it with putty, silicone etc will only ever be a temporary fix - if anything it wont be visible but could still be leaking from the back of the nut and possible behind the tiles ?? maybe
