Water leak HELP

[jon r]

Hi all, thrown myself in a the deep end and have bought porcerlain tiles for my bathroom, i have all the nesecary cutting tools so not a prob! (he says) I thought to make life slightly easier for myself i would remove the toilet so as not to have any awqward cuts, still going good. Waited couple of hours then put toilet back together then flushed, thats where the problem arose, water started leaking out of the bottom of the cistern down the pipe, i now cannot flush without water leakage. What can i do to stop this please?

Prob cos of the height difference due to tiles/ply.
you might need a offset waste for the toilet,best getting a plumber in if you r not 100% mate

Sounds like the cistern isn't sat right. Did you remove it from the pan? Have seen this before where the pan has been put back a fraction closer to the wall so the cistern was pushed forward causing it to leak

I take it you have a raised level cistern with an L shape pipe leading into the top/back of the pan?

If the water is running down the flush pipe, your flush pipe is not set correctly into the connector flange (where your pipe meets your cistern). Common cause of this is either your pan is to far back or forward. Double check that your flush pipe is straight. Sometimes the flush pipe can end up being a little too long if you've raised the floor but the cistern is the same height. If it is this, just cut off the top of your flush pipe to the same height you have raised the floor to. I'd check your first port of call with it either being too far forward or back.

If it is actually leaking where your flush pipe meets your pan, your flush cone is not set correctly into the pan intake.

Yes i completly removed the pan, forgot to mention i had lino down before so the pan has been raised by 100 cm. I have tried moving the pan slightly back and forth to different positions but to no avail. Would it be because it has been raised? Do i need to get a different flushpipe?

Might as well take the cistern off and check the seal and plate etc (depending on how it's fixed). #Peteablard is right, seals proberbly just moved whilst you've been lifting it in and out.

No, as above, just cut your flush pipe. Double check your flange has a good seal to the pipe though. You can seal this with Silicon but do not flush for a good 6 hours & make sure it is bone dry before applying

... so the pan has been raised by 100 cm...

Do you mean 100mm/10cm or actually 10mm!?

100cm = 1m (just under 4')
10cm = 100mm (4")
10mm = Just under half an inch

I took far too long replying to this and completely missed it's low level. Presumed close coupled. Ignore me been a long week......zzzzzzzzzz

 

[Bubblecraft]

I'm lost now, is it a high level or close coupled cistern?

I'm lost now, is it a high level or close coupled cistern?

I've just gone back and read his first and second post and from what he's saying i think hi/low level with flush pipe. Not closed coupled.

Been working a lot of hours last few weeks (also the reason i've not been very active on here). Presumed it was C/C.

Jon r - The guys are right. Your flush pipe is now too long. If the floor levels come up it will seat at an angle now. Needs cutting down.

 

[jon r]

Its a low level cistern, i dont know what a closed couple is ,( only being a DIYer ) the L bend pipe is about 15 inchs long and the leak is from the bottom of the cistern. Just been and cut pipe down by the heighy of the tile but it still leaks. I may do what somebody said and seal round the flange (think thats what its called) otherwise may have to go buy another flushpipe and start again

Here's a diagram to show you types

Is your flush pipe inserted into the flange on the cistern ok? If it is, you can seal around this with Silicon (outside only). If you have cut it too short, you can either drop the height of your cistern or buy a new flush pipe. They are pennies anyway.

 

[jon r]

Ah brill thanks for the diagram, its deff the low level cistern. But i am still baffled, ive tried all what everyone has suggested but it still leaks, but only when flushed. Think i am going to have to go to plumbers tmrw to see what they can come up with. Frustrated now ahhh

 

[Bubblecraft]

If the flush pipe is seated in the flange, put a seal around the outside with Silicon. Make sure it is dry before applying. Leave it over night & you should be fine. If you are still having problems with it tomorrow, then go & get a new flush pipe. Take your old flange, pipe & cone with you for a perfect match. You'll get your pipe & cone ok but there are so many different types of flange. Don't go to a DIY store. Goto Plumbcentre, Graham's etc. Better chance of getting it & at a fraction of the price

 

[jon r]

Thanks for that #bubblecraft im just going to look to see if i have any Silicon laying around in the garage , failing that will pop to plumbase. And thankyou everyone for taking the time to reply

 

[Bubblecraft]

No worries. Hope it works out for you without a trip out for a new pipe

Hi all, well managed to sort the leaking cistern prob, it turned out there was the tiniest of splits in the rubber seal that sits inside the screw fitting, but the new one i got had an o ring aswell, old one didnt, but never leaked before, but all sorted now. Finished bathroom floor, didnt realise i would be cutting most of my tiles with my plasplug!! Bought a sigma manual cutter thinking that it would cut anything, including porcerlin! Ending up snaping first 3, so gave up (is there a knack?) Ended up having to go got a new diamond blade half way though job aswell as blade blunt very quick, is this normal? (it came with plasplug) Anyway thanks to all again for advice

No worries Jon. Glad you got it sorted.
