Hi,
I am adding a second floor ½ bath where I need to plumb a toilet and a sink into a 3†ABS vertical drain that leads down to the basement. The location of the 3†vertical is such that I would like to place the WC directly above it. Can I put a sanitee 3x2x3 on top of the 3†vertical drain with the 2†outlet in the horizontal direction to serve as both the drain for a sink upstream and as a wet vent for the WC? The WC flange would basically be on top of the sanitee connected by a couple inch section of 3†pipe. The 2†wet vent will travel only 1 foot horizontally with a ¼†pitch when it will enter the wall and turn vertically with two 45 degree fittings. The 2†wet vent will continue vertically for about 2’ where I will attach a 2x1-1/2x2 sanitee. The 1-1/2†horizontal opening will serve as the drain for the sink about 2-1/2’ away where I will add a P trap under the sink. The 2†vertical opening on the sanitee will server as the dry vent for both the WC and sink and travel up through the ceiling and out the roof.
In the basement is where I will tie into the existing 3†horizontal (1/4†pitch) waste drain, downstream of all other fixtures from first floor, using a 3†wye fitting on its side.
Does this sound code acceptable with new 2006 UPC 908.4 wet vent codes?
The only other thing I could possibly think of doing is use a 90 El Heel and use the heel coming off vertically to server as the wet vent. And use a 90 deg long up to the WC with the dirty arm drain as short as possible; say 6â€.
Thanks in advance,
Howard
