In both our toilets the ballvalves had given up the ghost (we live in a very hard water area where everything gets really scaled up) and we were getting a constant drip out of both overflows. Rather than bothering re-washering them etc. I just bought a couple of new valves and fitted them yesterday. Thing is, they both seem to drip for a long time after filling - not sure if they stop at all, or just slow down. I can't see any leaks into the pan, nor does it seem to overflow. So I can't work our why the ball valves think the cisterns need more water - although in one of the cisterns there is not much room at all for the float so I wonder if there's a bit of resistance there? Have looked for a mini-float but no luck (does such a thing exist? The slimline float I tried was even worse.) Both do shut off if you hold the arms down or pour in a glass of water, so it seems the arm shut-off mechanisms are basically OK.
My preference was to fit Fluidmasters but the awkward location of the flush valves has meant going with the tradional bottom-entry ballvalve with arm and float (and even that was quite a squeeze). I'm really not sure what to try with this to get a quick shut-off and it's made for a really frustrating weekend. So any advice much appreciated.
Also, and on the same topic - I noticed on one of the toilets that the plastic backnut for the ballvalve that fits directly underneath the cistern was leaking a bit so tightened it with a wrench. Looking at the underside of the toilet, it looks like the last person to work on it also put a bit of sealant around the backnut. Is this worth doing? I'm finding it quite hard to tell if this is leaking at all or not - the backnut is pretty tight and there is also a washer underneath it, but sometimes it does feel slightly damp. Condensation etc on the tank can make it quite hard to tell, although I suppose it anything is seeping through at all it must be so little as to barely worth worrying about.
OK, that's it! Thanks a lot in advance for any tips.
