push button toilet cistern,i have tryed to addjust valve to stop the terible noise,but no luck, is it possible to strip the system out to repair or do i have to replace the whole system.
thanks mike...

Would be easier to diagnose if you could give a description of the noise. Is it whenthe thing is flushed or filling up. No you won't have to replace the whole thing at worse it will either be the flush valve or the inlet valve. At best its something else. Have you got a high pressure (mains) or low pressure (tank) feed and was the system yu bought for high or low pressure?

Cheers

the system is off the mains at a working pressure approx 2 bar,ish I was not asked at the time of purchase if it was to be used on a closed water system,the noise is constant on a charged cistern,

You still haven't described the noise nor did you say if you have fitted a high or low pressure valve.

Cheers

in the first instance i'd change the diphragm valve. easy to do, takes seconds and cost pennies, that may well solve it. if not then more info reqd re. type of noise and when it occurs, as has already been asked.

the noise is high pitched like bees buzzing,when cistern is full,it is only two years old and all plastic construction.I have an isolation valve which i have tried in different positions as well.

Best suggestion I can offer based on your replies is change the inlet valve and make sure it's a high pressure one.

Cheers

ardencaple,
You appear to be claiming that you get the buzzing noise once the cistern is full. If you cannot see any water coming out of the fill valve then look for a cause elsewhere. Since it is mains fed you may have a leak in the mains pipe and the all plastic cistern is amplifying the noise.
end

ended up changing out the plastic inlet "silent" fill system,everything OK now.
many thanks everone.
