I have built a room in the attic space and would like to add a
sink and a urinal to it.....
Is it acceptable to connect the drain line by "T"ing into the
vent stack from a bathroom below ??. It would only be liquid waste
The area I live in does not require inspections or permits, but
I'd like to do it in the proper manner if possible.
Any advice on this from informed sources would be appreciated...

Possibly, but consider that at some time in the future someone may
'extend' this bath and not realize what you did. Also, you'd have to
carefully inspect the existing vent line to ensure that it is able to
handle this type of usage. Most modern vents may well work fine, but
older stuff may not be up to the demand.
Which is not to say I recommend it! I would strongly recommend doing
it right, a proper crapper, and sink, with a decent drain. In the end,
though it would be more work, you'll probalby be happy you did it.
Well, if I decide to do it this way (being very very convenient for
layout), I'll make a point of feeding into it with a PVC pipe of no
than half the diameter of the stack pipe. Any plumber, or handyman,
considers a more agressive system will know exactly what I have done.
I only want to drain a little water out of a small sink,
provide cup of piss and a quart of water to flush it maybe 5 or 6
times a day....
Beats the hell out of climbing stairs and going to the other end of

You overestimate what others will 'know', but that's a different
Oh, I see. Your wife's planning to keep you locked in! Interesting
Think of it as exercise.
Overall, it should work (I think I said that) but were it my project,
I'd still give serious consideration to a proper quarter or
There is the potential that at some point you may want to sell the
house. And the real potential that building codes will be implemented.
And at that point, the (only?) prospective buyer wants to know if that
bath is up to code.
Good luck, and let us know how it works out. (BTW, you mentioned PVC,
so the existing plumbing may be better than I envisioned.)

Being in an area where there is no code enforcement, I'd suspect his
stack is not 'as it should be'... <g> That's the big problem, too many
unknowns-we don't know the specifications of the vent stack, how well
it was assembled, or much of anything at all.

(no, the established Usenet format is bottom posting...) makes reading
the thread *much* easier!
Didn't the original post say there was no building code/inspections?
If it didn't, then my mistake. I seem to recall reading "The area I
live in does not require inspections or permits,"... <bg>
No, you are correct in that something can be done right without
inspections, and I didn't mean to imply that if there are no
codes/inspections that the job won't be done right. If it came across
that way, I appologize.
