I have a duravit white toilet cistern. The toilet flushes ok, but then it continues, at a small amount to push out water and cistern refill again? What can I do to fix this?

SOURCE: my toilet cistern is continually hissing

Hi I have exactly the same problem, in fact it could have been me writing this - 3 toliets fine, main bathroom hisses. The Geberit flushing ciphen on the left (the smaller one) has been replaced and there is still a problem. If you look carefully,the water level needs to come up over the lip of an opening on the Geberit part and this causes the valve mechanism to shut off and stop the hissing. It is fine for about 40 minutes and then the hissing starts again if you don't flush it. The reason is that the water level has gone down but there is no obvious signs of where the water is going. It could be that the central flush mechanism is leaking slightly. I am going to replace this part next. If I were you I'd see if you are getting any water leakage into the pan when toilet not in use to see if the water level in the cistern is going down James T

SOURCE: after cistern refill outflow into toilet bowl

hi i would suggest your ball valve in the cistern needs ajusting remove the top of the cistern you will see the ajustment screw at the end fo the ball **** arm hope this helps

SOURCE: I have a Duravit toilet with a Geberit flushing

i think you have a snake in your bathroom lol

SOURCE: cannot remove top of cistern

There are some dual flush cisterns where you have to depress one button to reveal a cavity in the second button. Put a screwdriver in that cavity to lever out the second button, then release the first button and prise that out.

Underneath the buttons is a screw which must be unscrewed to release the cistern lid.

Not sure if this will apply to you... but if not, good luck anyway.

A fairly easy ( but messy ) fix - get a replacement tank to bowl gasket and bolt kit, shut off water supply, drain tank, remove bolts ( you might have to cut, depending on your water source and minerals in your water). Remove old gasket and clean surface with 00 grade steel wool. Replace gasket, install new bolts, remount tank.
Good luck!!
