Grohe system weeping - help!!

[rocksteadyeddie]

We have a Grohe push button toilet that is weeping water into the toilet bowl. Result being that periodically the cistern will refill and wakes me up! I have taken it apart and can't see why this would be leaking. The seals all seem to be clean ,and it is below the overflow level when the incoming water stops. Any ideas please chaps as it is driving me bananas? Thanks

If it not "overflowing" then it can only really be the syphon washer not seating correctly or a holed syphon though this is extremely unlikely

I had a similar problem, turned out to be the float fouling against the mechanism allowing the water to overflow into the bowl as they do not have a seperate outlet

Does it actually stop, or just slow to an occasional drip? If the level is slowly creeping up because the valve isn't sealing perfectly, that would cause this behaviour.

You need one of these:

Mine did exactly the same.

Hard to tell as it comes it at the bottom of the cistern. There is no visible sign of it - but it may be so slow that I can't see it

Have taken it apart and cleaned all the limescale and muck off but it doesn't seem to have helped?

Changed the bit in the cistern and that has solved the problem. Even on quite close inspection I can see nothing wrong with the washers on the old one so its a bit of a mystery.

Thanks to miniman who very kindly sent the appropriate piece.

No worries, glad it worked. Oddly enough there appeared to be nothing wrong with mine either. Must have microscopic tolerances.
