Toilet worked perfectly for 5years. For last 8 months have had an escalating problem, which three plumbers have failed to fix. All the following are happening but not every time toilet used.
1. Flushing continues after use.
2. Flushing continues after use if any taps turned on in bathroom during process.
3. Cistern fills and empties without anyone pushing flush button if washer on.
4. Cistern starts to fill and empty on its own when no water being used in house - e.g. at night or when I am out.
I am on a joint water supply- last of 4 houses.
Have listed these problems chronologically as they have started over last 8 months.
Three plumbers have been. First one 'mended' a valve. No good. Second one replaced valve with a Dudley Niagara Dual Flush Flushing Valve. No good. Third fitted a non-return valve. No good.
Sometimes flushing the toilet stops the constant filling and emptying, otherwise it stops of its own accord but that can take hours.
I am getting really worried now as no-one seems to know what is happening. Please can anyone advise? And how do I find a good plumber?
