Hi there,
We had a leak from our close coupled push button toilet that dripped on the floor. I read that the common cause of this was the coupling kit donut washer was perished so I bought a replacement kit and dismantled the toilet to fit it. This has fixed the problem but we immediately had another problem. Upon flushing the toilet water evacuates into the pan as expected but as the water fills back up in the cistern it is running out into the pan. This seems to stop once the cistern is full but the cistern doesn't seem to fill all the way causing the inlet valve not to shut and a constant irritating drip. I assume that it is not filling all the way as it has lost some down the pan. The flow of water into the pan seems to stop if you fiddle with the syphon but next time you flush it starts again. I find it hard to believe that it has become faulty more that we have moved something but I don't know what??
Any help appreciated.
Thanks!
