Hi all,

Found a couple of references to this topic in the archives but no real
solution.

We have a dual flush wc, one of those with two buttons in the lid of
the cistern. Anyway, the problem is that the thing is continually
letting water through into the pan.

I dismantled the "syphon" bit today and kind of figured out how it
works, there's a rubber seal that looked like it need a good clean. So
cleaned it and reassembled everything.

Still leaks, it does look like the pipe that the seal is attached to is
leaning slightly and may be causing it to not seat properly.

Anyway, does anyone know how to fix this? The whole unit is just over 2
years old.

If I have to replace it, what's the thing called?

cheers
Mitch

hi mitch
has the cistern got a overflow pipe? if it is the type with overflow
into the pan rather than an external overflow, then it may be that it
is ovefilling the cistern, ie water level too high. could be just
needing adjustment or washer on the ball valve

Bob,

I checked this, it has the overflow down inside the syphon, but no the
water level isn't reaching the top of the overflow pipe.
