Best concealed cistern wall hung WC

[toomuchworknotenoughtime]

If a thread exists elsewhere I apologise but I searched and couldn't find anything relevant.

I'm remodelling the bathroom from scratch and want to install a wall hung concealed cistern WC.

We have such a poor flushing toilet in place at the moment - blocks every week - that I've been trying to do some research on the best flush/cleanest bowls around but am a bit overwhelmed by the various makes and technologies.

I came across an inwall pressure assisted flushing system from Gerberer which looked promissing but (a) seems to be a technology not used in UK and (b) contact with Gerberer was that it fell foul (no pun intended) of UK water regs and wasn't available here.

I don't mind a "standard" flushing system. I just want one that won't block. And what about pressure assist? Anyone have any views and whether a concealed system is available here.

Thanks for any help/suggestions.

Are you sure it's the flush that's the cause?
No blockage, no sharp bends or other restrictions in the outlet pipework?
4 litre flush into an old 9 litre flush pan?

Oh no, I actually suspect a really cheap bowl coupled with a horizontal outlet (which I read somewhere isn't brilliant) straight out the back of the toilet, through the external wall and into the stack.

However, as I'm remodelling, and want a concealed cistern and wall hung bowl, I wanted some suggestions on the best systems available with emphasis on non-cloggability and bowl cleanliness.

Thanks

Are you saying there's no fall between the pan (bowl) and the soil stack?

Um, guess not, well not really:

Is that the problem? The vertical stack is just on the other side of the wall.

Your 'not really' looks like a roughly 14° fall. That, coupled with the distance to the stack (roughly 18"?) should not cause a problem.
