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
