    My close coupled cistern has developed a problem where it releases water almost continuously and sort of flushes every few seconds, shall I just replace the syphon or is it fixable?

    I reckon it needs Tomp's infamous "multimeter treatment." ;);)

    You're probably right, I had to change a low level cistern today and the whole lot cost less than £40, I was just hoping against hope that I wasn't going to spend any more time squatting in a toilet mopping up water.

    Fantastic TomP, I knew what the inlet valve was cos I fitted it but I didn't know I could leave the gubbins inside. :):):)

    Yup, just turned the syphon and the black rubber seal has a bit missing.
    Excellent advice as always from the pie eating, plectrum strumming, pint drinking, plumbing king :)
