In the bathroom I have an Armitage Shanks Tiffany close-coupled WC with
push
button flush. It is approx. 3 years old.

I have recently noticed that there is a very slight but constant trickle
of
water into the bowl as if the siphon has not shut off completely. This is
not a case of the push button assembly pushing down on the siphon as the
flow does not stop when the lid is removed.

I have replaced old siphons in my time but this type is new to me. I
don't
know whether there are any serviceable parts. Pictures at:

Can anyone advise me what the problem could be and let me know if it is
curable or will the whole assembly have to be replaced.


Looks to me like a flap valve rather than a siphon. These are [very] prone
to leakage. You can get a siphon of roughly the same cross section in B&Q
for under £10, AFAICR. Siphons don't leak (by their nature). They may stop
flushing however if they break.

I was hoping to avoid taking the cistern off the wall. It looks as though
the top part of the valve might unclip but I have been reluctant to force it
in case it snaps off and I would really have a problem!
