I plan to install a new upstairs bathroom toilet, basin and bath. All
three items will be on the same exterior wall. The basin is between the
bath and the toilet.

If I connect the bath drain to the toilet soil drain pipe, outside just
below the bath, a distance of about 8 foot, how much slope do I need?

Is it OK to connect the basin drain to the middle of the above pipe or
should I have a separate connection to the soil pipe? The latter option
would certainly prevent any water from the basin trying to enter the bath.


If feasible, I would have separate connections to the soil pipe. I
didn't and, whilst there is no real problem, I would not do so again. I
feel it was a bit sloppy.
