SWMBO wants a bog. Well, one that's not in the hall anyway. They are
*so* unreasonable, these women! ;-

Anyway, here's the new one, dry fitted (and kids instructed NOT to test!):

I'd like to box in that rear pipe - and the main stack. The rear boxing
is fairly standard - rectangular, about a foot high - or 2' high if I
take the flush pipe from the high level cistern through it, tiled on the
front with a solid wood lid that can be lifted for checking... I'll try
to make the front panel in 2 parts around the soil pipe, screwed on with
grout over the screws so it *could* be removed non destructively if the
worst happens...

Hang on a minute... I've just read the Floplast datasheet on their
AAVs... It says the AV/AF110 or AV/AF32's *can* be installed below the
flood line of connected appliances (the basin). The only stipulation is
that the AV/AF110 be installed 200mm above the highest wet entry to the
main branch, which on the diagram is the loo entry to that tee.

On that basis, I should get the AV110, shove it on a short stub of 110
into the top of that stack and run a shelf right over the top, which by
my reckoning, should be an inch or three above the loo seat.

mmm I might prefer a bit more vertically behind the bog? otherwise
inevitable ahem "splashes" may well cover the contents of the
shelves.....??
