leaking toilet at base of cistern.

[janej]

Hello.

I have a fitted toilet which is currently leaking at the base of the cistern. Having looked online there seems to be a lot of information about toilets with 'doughnut' type fittings. Mine does not have any such piece of rubber or anything, it just has a pipe which screws into the bottom of the toilet. Can anyone advise me about how to fix this leak?

I have a second and I believe unrelated problem. In my flat there are 2 bathrooms which are one either side of a wall, and the plumbing for the two toilets is clearly connected together, because for teh past few months or so, when you flush one toilet, as well as flushing away it also flushes up through whatever connection there is and into the other toilet. Does anyone know what might be causing this and whetehr it is easy to fix.

Thank you.

The waste from the one toilet comes up to the other when flushed? The waste from both toilets aren't connected some how are they? I have seen stranger things! It makes no sense, they are both share a water supply fine but that shouldn't share a waste connection.

Yep. I am guessing they must be connected. But the weird thing is that this problem has not always existed. No idea how it can just arise like this. It's a stupid situation - every time you flush one toilet you have to run around and flush the other one, but then that flushes some of the waste back into the first one.. it's a real waste of water. And time.

It's not unusual to have WC wastes that can back up through another one. Happens in hotels and blocks of flats all the time. One old dear flushes her dinner and the old dear next door gets it in her loo.

If it wasn't like it to start with then there's probably a partial blockage somewhere encouraging the waste to, at least initially, take the path of least resistance.

As for the toilet that you fitted, not sure what you mean by the flush pipe screwing into the pan. I suspect it's just a regular close-coupled toilet. Does it only leak when you flush? If so you need a doughnut washer. They're a couple of quid and won't be the hardest thing you ever fitted.

connections must be opposite each other in the stack, or the 4inch pipe has dipped if theyre in line - its weird how its getting round the trap in the toilet though - you have more problems with loosing the trap due to syphonic action than waste getting added to it.

Yes it does just leak when it flushes, fine the rest of the time. So I need a doughnut washer like the ones down this page.

Even though it doesn't already have one in place? These were what I was talking about earlier , it seems like they're always what people need to fix this kind of problem, but i wasn't sure if that was just because most toilets had one in the first place and they commonly wear out? My toilet has never had one of these. Can I just fit one anyway then?

Thank you.

its the nut on the flush pipe - probably leaking due to a disintergrated or unseated washer - turn water off drain w.c and unscrew - investigate rubber washer - maybe wrap some ptfe around it if your rough and re-tighten.

thanks - is there an easy way to fix potential problems with the 4 inch pipe? or any other possible solutions?

you can get a non return valve to fit on the pan connector. It like a flap but opens only one way. this would stop when flushing other wc waste coming up toilet (thats if there connected)

good idea everflow

 

[moony]

also stops rats coming up when your having a pooh
