A toilet-based first for me...

[WaterTight]

After nutting about with different doughnut washers (standard, wide thin rubber, thick foam) and even resorting to siliconing the latter in places still got leaks on flushing. Even reassembled uncoupled from inlet and overflow connections and with c/c bolts at various levels of tightness to make sure nothing was causing washer to slip. Still leaked - big style - every time.

Was changing from handle operated syphon to push button drop valve type. Reason being customer wanted more powerful flush. Finally concluded that toilet design couldn't take force of drop valve flush. Swapped to handle operated syphon and was ok.

Anyone else had this? Done hundreds of toilets and a first for me. Maybe been lucky. Wasn't even that old a WC.

By which I mean, filled cistern with a bucket and then flushed to make sure neither inlet or overflow connections was pulling cistern one way or other

There's a brand of toilet I've fitted in two different houses now and had this problem.

Don't know why it happens but it takes me a while to get right. I wish I remembers the brand so I can run a mile next time I see one

Had this a couple of times too. Can't remember the brand but remember it being the cheaper end of the range.

Even resorting to putting a small boat level on the cistern to make sure it was sitting correctly didn't work.

Sometimes the finish on the porcelain is slightly out so no matter how hard you try to line it up it just won't seal.

Annoying to say the least when a simple task holds you up!

Does the flush valve have a longer thread or larger nut stopping everything lining up?

I have had a couple of real nightmares with close coupled cisterns, I hate doughnut washers with a passion. Last toilet I fitted the doughnut washer supplied was never going to seal with the pan and cistern supplied as the gap between them was huge and the doughnut was tiny. Had to buy a thick rubber one and add a lot of silicone to get it to seal.

I used to replace syphons on a daily basis when I was subbing. Some toilets and cisterns would go back together no probs, others would need to be done 2 or 3 times before they stopped leaking!

A nice big ring on plumbersmait should do the trick. I've used it before to get around a dodgy pan, haven't been called back. Yet! :38:

Can be a nightmare for the next plumber though, cleaning it all off!

ever wondered why there are over a dozen type doughnuts?

 

[PlumbersMate]

Got taught 2 weeks ago, use LSX on the doughnuts, works like a dream

Is It just me, or is LSX just a small tube of over priced silicone...

It sets when surfaces are damp so can be very handy!
