the aforementioned toilet is now installed and is leaking! It is a BIIO
cistern (actually a B&Q 'Toilet to go' which is a close-coupled cistern)
which leaks into the pan so it's not disastrous. It is not overflowing
through the top of the overflow pipe as that is several cm above the
water level. My best guess is that the flush valve has not seated with
the seal washer and/or lock nut correctly and is leaking that way.
Should I remove the cistern and tighten the valve? (I think I have
tendency to under-tighten such things, due to a fear of
over-tightening!) The cistern does not appear to be leaking externally
at all. The area around where the cistern and pan meet are dry, as is
Is there anything else I should check for? Does anyone know of an
online diagram explaining precisely how these flush valves work?
Suffice it say that the enclosed documentation is of little help.
TIA as ever,
