We have a soil stack (I think that's what it's called) that runs down the
corner of our house from the upstairs en-suite down into the kitchen below.
The en-suite currently has a shower running down the soil stack but no
toilet. We would like to add a toilet to the stack but quite a few plumbers
that i've had look at it have said that we're not allowed to install a
toilet into a soil stack that runs through into and is shared by the
However, one bathroom installer has said that it's not a problem. He's
already done the same for a relative of mine who has the exact same house
and did a blinding job and they've had no problems at all.
What I would like to know is, given the afore mentioned, will it conform
with building regs? Or will having it done be OK but will be opening a can
of worms if I ever had to sell the property?
