Don't connect to the bottom of an existing drain. You would be creating a new low point for your system. You must pitch down (at least 1/4" per foot) to either level or above the existing drain line. Consider a sewage ejector if it's real important for you to add this to your basement.

You should connect to a vent that goes through the roof. It is illegal to vent below a window or other opening, and if you vent to anywhere else at grade, you're not going to want to spend much time around that part of your yard.


: Unless you have something other than the common basement, the headroom would be almost non-existent for all but the shortest people. Other than that, and the fact that potential future buyers might not wish to have a "walk up" bathroom, it should work.

: : I have a the typical non-plubed basement problem, and would like to know if the following solutionis viable:

: : The toilet/shower I would install is within 5 feet of a main drain pipe which drains the 1st floor toilet. It's a 3" pipe.
: : I would like to build an elivated for the basement bath, elevating the toilet and shower stall maybe a foot or so,
: : then running the drain pipes under the elivated floor, connecting to the bottom of the nearby 3" drain pipe.
: : I have a vent pipe which is easily accessable, however, this vent pipe appears to vent out the side of the basement. Is that usable?

: : Given that I could build an elivated floor, how much slope is required for the shower/toilet to drain properly? That
: : would be the clincher, as it would determine how high I would have to elivate the floor.

: : Thanks for any help.
