Question on attic bathroom

Posted by AndyS on October 19, 2008, 2:08 pm

Andy asks:

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
and
low flow.

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.

if the stack is 3 inch or bigger (as it should be) then there's no issue
about "decent" drain or "being up to the demand"

Well, if I decide to do it this way (being very very convenient for
my
layout), I'll make a point of feeding into it with a PVC pipe of no
greater
than half the diameter of the stack pipe. Any plumber, or handyman,
who
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,
occasionally, and
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
the
house.....

Thanks to everyone for their inputs...
