leaky cistern

[Scarlett]

I think that's what it is anyway. A get a puddle of water on the floor behind the loo after flushing. My friend came over a year or so ago, fished about under the lid and fixed it. I think it is something to do with the ballcock being too high (?) and too much water filling up after flushing, and leaking out somwhere.
Anyone got any ideas how I can fix this? Surely I don't need a plumber?

Ok, so you know what the ballcock looks like, yes? Follow the rod down to the valve and screw -in the plastic fitting that allows the water out. Try just a couple of turns, then test by flushing and see what happens. Sorry, I'm not a plumber and I'm probably not calling things by their correct names. : )

If the water appears after flushing, it's unlikely to be the ballcock - if it was too high, you'd get an overflow when the cistern filled.
It sounds more like a leaking connection, either at the base of the cistern, or where the pipe connects to the pan.
But check too, that the ballcock valve isn't leaking and spraying water about inside the cistern when it starts to refill it.

We had a similar problem. In fact it was condensation. The toilet fills up with water direct from the mains instead of from the loft tank and this is very cold. If you see beads of water on the cistern this is likely to be the cause.

On a more smelly note it could be a leaking soil joint where the contents of the pan are flushed into the drain.

It won't appear brown or anything disgusting like that but it can smell a bit.

If its not that then a leaking connection or condensation is likely to be the cause.

The ball valve won't have anything to do with it unless the connection to the water pipe is leaking, but that's quite obvious.

Hi Scarlett bit more detail would help like Heathfield pointed out probs with ballvalves results in water from external overflow running , the joiont of a close coupled cistern to the pan is not normaly liable to leaks, so it looks like Matty sugestion about the pan conector is the culprit only leaks on flush.
