When the push flush cistern is flushed it fills correctly and the float shuts off the valve correctly. However, after a few minutes a trickle of water enters the cistern via the valve and continues without shutting off. It is as if water is seeping into into the pan which is keeping the valve slightly open. The system is only 2 years old. I have checked the seating of the inlet to the pan and this seems OK.
I have the same problem with my Macdee Duo Compact 6 litre Cistern after I have flushed the cistern refills and then 10 minutes later I can hear the trickle of water in the cistern I have tried turning the plastic screw setting but unsure which is the correct way to adjust the float - the noise is driving me mad and I do not know how to fix it your advise please.
Re Single push button cistern - I had the same problem as Sarah, a constant trickle. I Had to get Dynarod out to it, but not sure what fixed the problem. However now I have a new problem about 10 mins after flushing, the toilet starts making a noise like a motorbike starting up (don't laugh) the silver flexible hose attached vibrates, I then have to slightly depress the button to release a little bit of water and it stops. Next time it is flushed again the same noise after 10 mins. Any ideas?
