noisy cistern
Posted: Mon Oct 25, 2010 5:56 pm
MY TOILET HAS DEVELOPED A LOUD NOISE WHEN IT HAS BEEN FLUSHED. IT IS NOT A NORMAL BALLCOCK TYPE I THINK IT MAY BE A SYPHON CISTERN. iT USUALLY MAKES A NOISE JUST AFTER THE BUTTON IS PRESSED AND THEN AGAIN JUST BEFORE IT IS FULL. I HAVE TRIED ADJUSTING THE FLOW INTO THE CISTERN BUT IT HAD LITTLE EFFECT.
