The plumbing assembly connects a sink waste line running at a minimum slope of one-quarter inch per foot to a foot vent and main waste line. The return bend at the top of the vent is constructed from a single piece or an assembly of forty-five degree and ninety-degree elbows, extending at least to the sink drainboard height. A rise vent connects into the nearest wall, featuring an accessible cleanout with a sanitary tee above the floor. Wye-branch fittings manage the transition between waste and foot vent lines below the floor slab.
