leaking close-coupled cistern

[paul]

I discovered a leak which I think was coming from the bottom of the cistern where the exit pipe runs to the bowl. The cistern is enclosed in a nice cupboard :-((( We had clean water seeping between the bowl and the floor. I think a very slow leak has been running from the exit pipe and then ending up behind the bowl and the exiting on the floor

With much swearing I got a hand in and tightened the joint as much as a could (perhaps 1/16 of a turn.) the leak is now much more and seems to occur when the toilet is flushed - as witnessed by water coming through a joint in the 'skirting board' bit of the cupboard. - ie a different place.

there isnt enough space to get a mirror/torch round the cistern to have look and see what s going on . there is just enough space for a forearm.

IS there a likely source of the leak before I (or perhaps someone who knows a bit more about it ) removes the bowl, takes the cupboard apart and has a look ?

Is there room for a digital camera to take a flash photo? You'll probably have to use Macro mode.

Your header says close coupled cistern but you seem to refer to a low level cistern (that is a cistern separate from the bowl and connected by a short flush pipe). If it is low level then try to get a hand round the back where the pipe enters bowel and find out if the leak is coming from there (very likely). The pipe may have worked a bit loose and just needs pushing back into the connector.

Never a good idea :-) Mind you, I've found them boxed in & tiled over.

Soounds about right.

Hard to tell exactly where leaks like this actually start because the water runs along surfaces until it falls off & then appears in a different place.

Only three places it can leak; (a) where the siphon goes through the cistern base & is secured by a large nut underneath, (b) at the joint where the pipe connects to the thread on the bottom of the siphon, or (c) at the push fit finned connector at the back of the toilet bowl.

If it appears only to leak when flushed you can rule out (a).

Dry everything off with kitchen roll, flush & feel around for a leak.

My money is on (b).

Sounds like the cupboard is coming out :-)

OMG - what sort of flush does it do?

[Heliotrope Smith]

Mmmmmm that looks like the number 2 flush.
