The ball valve in my toilet cistern is dripping from the blue nut nearest the plastic inlet - it's pretty much the same valve shown in this article:
Can anyone tell me whether the valve can be taken apart and cleaned/resealed with some sort of waterproof sealant, or whether I should/can replace any washers in it?
(I also found that whoever put it in decided against drilling through the wall for the overflow, and felt the floor was a better place for excess water!)
Alternatively, should I just replace it? I'd rather not do this unless I have to - the isolation valve doesn't *quite* stop all of the water so it's a case for the freezer spray I think.
Incidentally, there are a few valves in the house which seem stuck or not very effective. The stopcock is under the kitchen floor and is difficult to get to, to say the least. Are there "remote control" valves available, or should I just get a stopcock key and shut the whole lot off from the pavement?
Thanks in advance
