Rimless toilet flushing problem

[Shotokan101]

Hi,

I've had two Nuie Rimless toilets installed and both are showing the same "flushing problem".
Both toilets have been installed with new "3/6L dual flush" concealed cisterns.
Even with the full 6L flushing both toilets do not flysh a considerable area at the "top front" of the pan.

Installer is being told by the supplier tgat "all Rimless toilets" are like this.

I'm obviously not happy if this is tge case, which I don't see how it can possibly be true, and am posting here to get some additional feedback.

Thanks,

Jim

How much height above the top of the pan to the bottom of the cistern do you have, I find rimless need pressure

Not true. Ideal Standard ones flush right round to the front.

Thanks for the reply - hard to tell for sure, but definitely not a great deal - maybe 4-6cm best guess.

Any suggestions for how much height would, be "needed"?

Looking down inside the cabinet where the cistern is mounted I guess that by redoing the mounting then the cistern level could possibly be raised by a maximum of about an additional 6-7cm.

I would do an external test eg toilet on the grass and a longer flush pipe to see if it changes first

Harking back to the old days of lead pipes, thick walled copper pipes, no bending machines, no power tools, no on site electrics and everything was fitted by the use small hand tools and toilet pans had closed channels around the rim that had holes in to disperse the water around the bowl via a high level cistern. If one of these stopped washing around the bowl properly we used to get an old thick wire coat hanger, straighten it out and poke it up the holes in the WC channel to clear them out from lime scale and other undesirable material. I always carried a wire coat hanger around in my tool bag back in those dark days where we'd build entire housing estates with no power tools or electrics, just old cement mixers and the only modern thing was a JCB.

Moving onto todays modern pan. In the back of todays pans, where the flush pipe goes is a plastic injector or jet (for want of the right name for it) that when the WC is flushed this 'injector' speeds up the flow of flushed water from a CC or low level cistern so it can wash around the whole bowl (on a rimmed bowl).

Now, I'm wondering if this 'injector' is missing on your rimless bowl (it has happened to me a few times so I always check there's one fitted when getting one from the stockist) and therefore not washing the complete bowl area on your particular WC.

Have a look to see if there is on tucked away inside the flush pipe aperture.

Hope this helps.
