Hello Group,

I'm working for a friend on a gut job rehab, and his architect seems
inclined to provide plans with no mechanical details and no place to
put waste stacks.

In the interest of planning the job, I'm wondering, Can a Toilet, (as
part of a bath, including shower and lavatory, or half bath including
only lavatory), be attached to a Horizontal branch of a waste stack?
I've only ever seen them attached to the vertical sections of the
stack. If so, what restrictions are there on the length of the
Horizontal branch.

I've been reading the 2006 National Plumbing Code, and I can't seem to
find the answer in there.

Incidently, I found the National code on the web at this location:

Thanks for any information you can provide:

Best, John
