Just moved to a new house with a rather old downstairs WC. It is a large low level cistern connected by a pipe to the back of the pan.
When we flush the loo there is a huge deluge of water into the pan, I would reckon about 15 litres or more. The water comes out fast and is reasonably well distributed around the rim. Despite this we get a gradual build up of poo at the bottom of the bend over a couple of days. It appears to be almost flattened but no amount of flushing seems to shift it.
When we moved in the owner had put one of those blue tablet things in the cistern which obscured the problem for a day or two and they also left behind a loo brush (this was practically the only thing in the house that was left behind that was not nailed down) so clearly the problem is not new.
The U bend seems unusual in that it has a kind of flattened bottom to it rather than being a smooth curve. This forms an angle where the bottom of the bend meets the back of the bend, if you can visualise that, and it is at this point that the build-up occurs.
The following is an ASCII art attempt of a vertical cross section of where the bottom meets the back. The lower case "o" characters are where the poo builds up:
[code:1]
\ \| /
\ /
\ooo__/
Back Front
[/code:1]
Anyone come across this before?
Would cleaning any limescale out of the rim help?
Could this pan actually have been designed to work with a high level cistern?
Would it be worth getting a plumber in before we go out and buy a new WC?
All assistance gratefully received!
