Hi

I have just fitted a Wirquin dual flush from B&Q to our close-coupled
toilet. Works fine but there is a very small leak from the connection
between the toilet and the cistern. I took it all apart yestereday
evening and nipped up the back nut but the leak is stilll there. I
don't want to overtighten it and I have read elsewhere that its not a
good idea to put a sealant on plastic/rubber fittings.

I am assuming that tightening the doughnut washer by doing up the wing
nuts won't help here (the toilet has not been flushed).

Any suggestions please?

David

Do you mean it leaks all the time - not just when it is flushed?

Does it leak more when it is flushed?

My new bowl and cistern from B & Q leaked at the doughnut joint, IME
where the pipe leaves the cistern isn't usually a problem. Took mine
apart, fitted new doughnut, OK now. Best not to use sealants,
otherwise may be very difficult to seperate later. BTW, on my
cistern, it has to be removed from the bowl in order to fit a new
syphon flap-washer, as the syphon is one-piece. Old one had a joint
in it, bit with the flap-washer lifted out for maintenance. All down
to cost-cutting!
