Toilet leak when flush - looks like seal between cistern and bowl
paulfoel
Looks like the cistern doesnt fit absolutely squarely on the back of
the bowl (Cheers Barratt!). Consequently it looks like its all got
gunked up and started leaking a little.
Am I right in saying the bowl isnt fastened to the cistern normally
(it doesnt look like) and that cistern fastens to wall, sits on bowl/
base which is screwed into the floor?
I'm guessing best way to fix is to remove cistern, clean out crap,
replace seal and re-fit (a bit squarer) ?

The bowl and cistern are fastened together by a plate and bolts which
are fastened by nuts or wing nuts under the bowl ..if you look
underneath you will see the ends of the bolts and the securing
nuts.There is also a rubber doughnut type ring that seals the whole
thing .Best to get a replacement ..Plumbers Merchant,Shed or Screwfix
or Toolstation then take it apart ( turn off water and flush first
..there will be residual water in the cistern after) and clean
everything then replace the plate.seal and bolts then refit .The
cistern is screwed to the wall but afaiu that is just for support .
This what you need

Mebbe a good time to check the syphon inside and the pan connector at
the rear .

Exactly wot he said, but don't buy such a kit from Homobase. The bolts in
theirs aren't fully threaded and won't tighten enough to seal. DAMHIKT.
An application of Plumbers Mait won't do any harm.

Often as things settle a leak can develop. You may get away with tightening
the bolts. However - take care not to stress anything. If the cistern is
tight to the wall then you could crack something. Could it have been moved
by an over-weight person? Is the WC stable - if it can rock then this needs
fixing.
Aim for the cistern being tight to the WC - the wall fixings are just
secondary support. Don't risk pulling it back against the wall if it doesn't
want to.

I hope you're not discriminating against fat bastards.

The cistern is normally placed onto the bowl with a foam sealing ring
(commonly called a doh-nut.) then 2 brass bolts with rubber washers pass
through the base of the cistern and through the bowl being held with another
washer and wing nuts.
The cistern is then held to the wall with 2 screws in the back of the
cistern above the water line.
Over time the doh-nut degrades and a leak occurs or the rubber sealing
washers rot again causing a leak.
Most DIY or plumbing merchants stock new parts for a few pounds.Some even
carry a kit of all new parts for about a fiver.
The trick is to fix the cistern to the bowl first and then fix to the
wall.Don't over tighten as the parts may break.

There are two common types of do-nuts. One is a simple (spongy)
rubber ring, the other is like a flattened hemisphere. As stated
above they only cost a pound or so so get one of each.
Take great care with the bolts through the bottom of the
cistern - usually fastened to a metal flange rather than through
the pedestal. The flange then has wider mounts to attach to the
bowl. The bolts from within the cistern are usually brass and,
although they won't seize up, they may corrode and be difficult
to free. If so then you may compromise the water seal in the
bottom of the cistern and gain a leak (sic!) Have a couple of
(bath) tap washers and a tube of silicone sealant handing in case
you need to re-seal; note if you do re-seal the inside of the
cistern should be clean and dry until the sealant has completely
cured.
If you have some Waxoyl or silicon grease, wipe a little onto the
full surface of the do-nut before you fit it. Not only will it
help the sealing action, it will also keep the rubber soft so
that it maintains the seal as it flexes with the mutual movement
between cistern and bowl. Also, whilst you have the cistern off
check and if necessary repair/replace the wall plugs where the
cistern is attached, and as you are going to have the cistern
apart, replace the water lift unit (the thing that actually
creates the flush) - they only cost about a tenner and it will
save you another job down the line.
Don't be afraid of it - the job is quite simple really, just
fiddly.

Cheers everyone. I can see the wing nut underneath but cant see it
coming up inside the cistern?
Looking underneath it looks like the seal has got all manky etc with
stuff leaking out. Looks like I'll have to take apart. Doesnt look too
difficult.
The Medway Handyman
Some bolt through the cistern - bad idea IMO, some have a steel plate held
by the nut that also holds the siphon in place. You can see it in the
picture here

It isn't.
Stuart Noble
If using a replacement kit, make sure the plates are the same thickness
as the old ones. If not, you can end up with the cistern being a
fraction higher than before, just enough so that the screws into the
wall don't line up.

Ooh no, there are hundreds. I like the ones filled with custard.

Do they become don't-nuts when they fail? :-)

Ah. Looking underneath that looks like it.
Looks like its been leaking slightly and all black gunk has caused it
to expand apart...

so I understand how it bolts up from underneth but how does this
connect to the cistern?

When you take it apart it will become obvious but part of the syphon (
which creates the flush) protrudes down through the cistern and down
through the metal plate shown in
http://www.toolstation.com/shop/Plumbing/Toilet+Fittings/Close+Coupling+Kit+Metal/d20/sd2835/p85615
and there is a large plastic nut holding it all together ...along with
the rubber doughnut seal ....the long bolts fit in to the sides of the
metal plate and go down through the back of the bowl and are secured
by the nuts underneath and the screws securing the cistern to the
wall hold it steady .

has no bolts through its base ,instead a pressed steel plate is mounted on
the outlet shaft of the siphon assembly and this carries 2 bolts which
locate in the pan .
This is why you can't find any bolts as they are between the pan and
cistern.
Removal is easy (unless rusted solid) simply remove the 2 wing nuts keeping
the steel & rubber washers then remove the wall fixing screws and the
cistern is free.
IGWS make sure the water inlet & overflow are disconnected and the cistern
is empty.news:3379a8e1-dcf0-45da...@e27g2000yqd.googlegroups.com...

Sounds like the old pull chains, of my youth, if one even lived in a
house with 'mod con', are no more?
The holding of one's nose and dramatizing the downward pulling of a
chain was a very effective way of saying something would not work or
should be disapproved! {:-)

theres a large plastic nut that holds the metal plate in place (the nut
screws onto the base of the siphon). The bolts from the plate then hold the
plate (and cistern) to the toilet.

Got the part from toolstation now. Cheap - £2.49. I bet it would have
cost more from B+Q !!!!!
I guess it'll all become clear when I get the whole lot apart....

Nearly �6 in Homobase - thieving bastards.
