Small problem with the bathroom we did in April last year :-}
We've got a variflush drop valve installed, but for some reason, it doesn't stop after the water has drained.
Tapping the panel that the flush button is mounted in (sometimes several times) will make it go "clunk" and seal again, but it's a pain having to stand around to do it.
Anyone got any idea what makes them "stick" ? (i'm wondering if the cable sleeve is bent too tight or something, preventing it from resetting itself)
