I've got a rather complicated soil pipe run to install and I'm at a
bit of a loss as to whether what I'm trying to do will even be
possible. A picture's worth a thousand words etc. etc. so here you
go:-

The first problem is that as soon as the soil pipe leaves the building
through a 2ft thick brick wall, it needs to turn 90 degrees and head
towards the soil stack. Can I even put a 90 degree access bend
directly against the brickwork like this, or will it cause the
adjoining soil pipe to be too far away from the wall to attach the
supporting clips?

Can't you build the bend slightly *into* the brickwork - as long as you can
still get at the rodding point access cover ok?

Secondly, I'd like (if possible) to run my sink waste into this soil
pipe, to avoid the need for a second waste pipe to weave it's way
around the w/c etc. By my understanding this means I'll need some
form of horizontal T connector directly attaching to the pan. I'd
then run a standard section of soil pipe to the right of this, along
to the sink, with a screw-on end cap for access. The sink would just
have a single vertical waste drop (hidden behind the pedestal) and
attach to the soil pipe with a 40mm strap boss.

Can you actually get a T pan connector that would allow this? I
assume public lavatories must have something like this, allowing
several w/c's to connect to the same horizontal soil run?


Does the soil pipe *need* to extend along to the basin? Can't you bring a
smaller pipe along, and connect it into the large pipe near the pan?

A good source of inspiration may be to visit the toilets in a few of your
local supermarkets. They seem to use exposed soilpipes with all sorts of
things connected into them. May well give you some ideas!
