Toilet cistern syphon unit part 272.324.KG.1 dated 30.06.2004. I have a problem in that there is a permanent seepage from the cistern into yhe pan, as the level drops so the inlet valve opens allowing it to be restored. This is continuous and happens every 20mins or so. Is there an adjustment or does it need a new washer somewhere? The old fashioned ballcock never gave the problems these clever new plastic contraptions do!!

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

I would recommend calling Duravit USA at 1-770-931-3575 as a starting point. After some Q&A they should be able to help you get in touch with the nearest supplier to you so that the part can be ordered. Many manugacturers wil not work directly with the retail public. Also many of them require minimum purchases from their vendors. Y might be required to prepay s&h up front to expedite your item. Sometimes even that is not allowed.

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.
