I am going to be putting a toilet under the stairs of the house I am
renovating and am puzzling a little over the connection into the drains.

I probably need to discuss the options with the BCO but was wondering if
it is possible to join it into the existing soil stack!

The house is a Victorian terrace and the current situation is that the
main sewer pipe runs along the back of the houses (ours is third in line
of 6) and the only current connection into the drain (as viewed from the
inspection chamber) is the main soil stack. I haven't excavated around
the bottom of the stack yet but there are also an old (outside) WC
connection which branches straight into the sewer pipe outside of the IC
and a rainwater gulley which does the same on the other end of the IC.

there is a diagram and photo at http://www.engelside.co.uk/toilet.htm

The original toilet is going and the wall between the kitchen and
conservatory is too.

I don't particularly want to start making major changes, building new
IC's if it at all possible so I was hoping that I could run a connection
from under the stairs to the bottom of the soil stack.

Any views?

Cheers

Martin

I'm not clear just where your new toilet is going. I assume it's on the
ground floor, somewhere near the stairs? Is it a suspended wooden floor
downstairs, and you want to run the pipes under it? Or are the floors solid?

From the photo, it doesn't look as if you've got much vertical height to
play with to get a suitable fall. The stack looks as if it goes into a clay
pipe - then straight into the IC so there's no real possibility of
connecting there.

The toilet which you're removing presumably has a clay pipe under the floor?
Couldn't you cut off the upturned bit of that and connect your new toilet
into the horizontal bit?

Hi

I have updated drawing to show new toilet position. Floor in Dining
room is suspended timber, Kitchen is concrete. Under stairs is concrete
but could be replaced with timber.

I had envisaged the connection running under the concrete floor in the
kitchen as it needs replacing anyway. That way I think there is enough
fall (the sewer is about 600 mm below floor level).

The problem as I see it with connecting into the old soil pipe is that
it doesn't run into the Inspection Chamber and therefore provides no
rodding access.

Cheers

Can you not just extend the inspection chamber. It's a job far worse
thinking about than actually doing ! That way your new pipe could just
run into the extended chamber roughly where your disused one is now
situated.
