I have an Impulse 'Cascade' toilet cistern (oval push button). There is water leaking slowly into the toilet pan and a small 10 second flush happens every 30 minutes or so as the level drops.
I suspect the washer at the base of the flush valve unit needs renewal. Is this flush valve removable without taking the cistern off the toilet bowl?
