Default Toilet leaking from flush pipe

My toilet was leaking slightly from where the flush pipe goes into it
whenever we flushed the toilet.

I renewed the plastic bung that the pipe goes through and also the
pipe as it looked a little short to me.

It is still leaking!

There is only the pipe going through the plastic bung that fits into
the hole at the rear of the toilet. No washer or seal of any kind.

Should there be something else there to stop the leak?

Those polythene "bungs" are rubbish compared to the older rubber
sleeve-type. Sanitary silicone is the usual fix, but I've had it not work
first time.

Check first.

Is the leak coming from the flushpipe entry to the pan?

Have a look at the flushpipe exit from the cistern, it can very often be a
leak from the back of it running down makes it look to be leaking from the
pan end.

If all is ok there then it could be that the flushpipe could now be too
long or the cistern outlet is off centre from the pan connection.

Mine too but a good dollop of silicone sealant has cured it. You need
to get everything completely dry and clean though and leave the
silicone for several hours to set. Once it has it remains flexible
enough to resist any movement in the components and should be a long
lasting cure.


Fernox LS-X worked for me. It has the advantage over normal silicone that
the surfaces don't need to be dry.

Is there a poor moulding of the china?

I have had a similar experience.
There appear to be two "types" of seal - one is a slightly more rigid affair
with large sealing fins (this is the type I had leak) - the other is more of
a bung which fits far more snuggly both to the pipe and to the bore of the
flush pipe entry.
I have used the bung-type twice without problem.
As another poster has noted, there may be a ridge or similar in the bore of
the flush pipe entry which is allowing water to track past the seal you are
using.

Default Toilet leaking from flush pipe

I popped into Focus DIY today to get a few things and saw a rubberish
bung for this very job!

It looks like rubber and feels like rubber, but you never know these
days.

Anyway, it looks like it might well provide a better seal. I have not
noticed any irregularity in the surface of the toilet but I will have
a closer look.

No, if the surfaces are clean and the flush pipe goes into the bung far
enough (and straight) it should seal OK, though sometimes the hole in
the pan is uneven and can cause problems sealing. Plumber's Mait is the
traditional stuff for dealing with problems like this, and silicone is the
bodger's favourite :-|. If I'm in bodger mode I use Toolstation's stixall
which is like silicone but sticks to wet surfaces too. I think it's a
"Sticks Like Sh*t" knock-off.

Umm.. Lots of good advice from others but... *looks a little short* may
be the cause.

My daughter had a similar problem. In order to create an inch or two
extra space in a microscopic toilet the plumber had fitted the pan too
close to the rear wall. The consequence was that the plastic bung was
being distorted by trying to seal on a section of pipe which was neither
round or parallel to the pan.

By far enough, do you mean as far as you can push it?
I'm about to install a cistern to marry up with one of the old 2 part WC
bowls where the soil pipe is straight down rather than out the back (so
changing it would be a pain). I can see the cistern has to be positioned
accurately in terms of height for the flush pipe to be straight but I
wonder how much leeway there is in the length. Is it usual to shorten
the pipe if the cistern is closer to the WC?
I'm trying to gain a couple of inches behind the new cistern to put some
insulation on the wall, which I reckon I can get with a slimline plastic
job.
