The idea of the overflow is not just to discharge the excess water but

waste pipe you won't know that it is overflowing, unless you fit a
tundish. You can get sealed clear ones that fit inline in the overflow
pipe.

Thanks to the replies concerning the 'tundish'. That would certainly
be an option. I'm curious about the WC syphons with integral overflow.
They sound ideal - from a visual point of view at least.

Virtually all new WCs have an integral overflow - the regs changed a
few years ago, and now most have changed over.
