How Good are New Toilets?

Not only are modern 6L toilets often unable to flush properly, but these small cisterns are too small for the reliable and leak free siphon flush system to work. So instead they are fitted with a bottom outlet valve which often leaks - and since this is into the toilet bowl this leak goes unnoticed.
So the "save the planet" move to tiny toilet cisterns to "save water" actually wastes it in two ways - needing 2 or 3 flushes instead of one, and continual unnoticed leaks from the cistern into the toilet.
Law of unintended consequences!
 
Modern flush valves are far more efficient than the old flapper valves plus you can usually adjust the fill valve to use the water required to clear the pan.
 
In Germany it's fairly typical to have a toilet where your output is held on a shelf for you to inspect before flushing. Can be a useful diagnostic tool for various serious conditions so not exactly an horrific idea

I have used those types before. V odd. I often spend ages on the bog in the morning making sure that I am completely empty given that I work in people's homes. With the German/Dutch loos, I would need about 5 flushes just to keep the smell down.

Ultimately, with a UK loo, I can just look down into the water.

With regards to skid marks, some are far worse than others. You have to stick loo paper to the back of the pan, either that or flush every five or ten minutes (and then use the loo brush).
 
If I'm in there longer than a minute, I have Av shouting up, asking if I'm still alive :-)

I am happy to sit there for 30 mins. Like I said, I want to be empty when I leave for work. 30 mins in the morning Vs using the customer or pub loo later in the day- no brainer (IMO).
 
I've found new toilets are a bit hit and miss, when I say new I mean anything with a 6l and under flush. My ~20 year old close coupled villeroy and boch one always needs 2 flushes, my brand new rimless vitra toilet with a concealed geberit cistern is almost always spot on. I've definitely seen many standard toilets better than mine, also some worse, and for the rimless ones some are hopeless, some are great. So very hit and miss and I'd say going with the 'good' brands isn't always a safe bet.
 
As an aside...

Not related to flush rates, but why are some loos designed such that they leave skid marks at the back?
I had a toilet in my last flat that was very poorly designed. It had a shallow slope down to the water and turds tended to fall on that then roll or slide into the water, or just splat onto the slope and stay there.

A German obsession I believe. Sounds disgusting to me!
I recall one in a friend's house when I was younger that filled the bowl up quite a lot and swirled before sucking nearly everything out with a siphon action
My brother has one of those. It works very well. Next time I visit I'll see if there's a name on it

But why? It's only poop..


One of the most bizarre toilets I ever used was in America.. not only did it lack a cistern and didn't flush very well with the low pressure, but the water level was only a few inches away from the user, which seemed to make it so any output started being supported by the water before it had broken off under its own weight. The boys were fascinated by this and practiced/competed who could get the longest unbroken turd curled round the bowl.

Small things
 
But why? It's only poop..
That's why :giggle:. The problem is it doesn't always flush off the shelf too well, needing more frequent cleaning. I've seen Portaloo-type toilets in UK designed for some reason like that. Flushing works poorly, the next user, and the next, deposit their load on top and there's soon a highly unpleasant mess.
