I have a 30 year old bathroom suite with a double syphonic trap toilet, which is blocked......I think!? When I flush, the water rises about half way up the pan, then the water settles back to the original level 15 seconds after the finished flush. The waste isn't flushed out so I throw a few buckets of water down the pan and it goes fine.
I wasn't sure so I took off the cistern and replaced the syphon and water intake as they were both very old. The flush is much stronger now, (and quieter), but the water still rises about half way and settles back down again. I then put sodium hydroxide down, followed by a jet wash followed by copious amounts of bio-degradable gunk and bucket loads of cold water. Nothing is working!
The only thing to help slightly is very hot water , but as soon as I flush with cold water, same problem. Is the loo blocked? Do I need to remove the toilet completely, as I am not sure how to reseal the whole thing. Also will imperial toilets have metric seals/pipes etc etc?
Any help would be greatly appreciated as I'm at a loss! There are no kids or anyone else so I know nothing went down there.
I took the old one out, and put the same type, back in. The only difference was the new one was slightly taller 1/2" than the old one. It all went in ok, and as the flush is stronger, I has hoped the blockage (if there is one) would be flushed away.
I have noticed a slight leak under the cistern, so I took off the cistern again and tightened the siphon and used a bit of plumbers mate and thats stopped the leak, but still the water rises before dropping back.
I'm scratching my head before the bank holiday weekend because I will rip off the bog and see whats going on!
