Universal tail piece for installation in a water waste line

A universal tail piece for insertion in a waste pipe of a water drainage system readily adjustable for multiple uses including channeling a portion of the waste water from a primary source to a floor drain trap for priming the same and for draining waste water from a secondary source through the waste pipe along with the waste water from the primary source being drained, comprising

• (a) a main tubular portion adapted to be connected to a waste pipe in a substantially vertical position, and including an upper inlet having means for connecting to a waste pipe, a bottom outlet having means for connecting to a floor drain trap, and a main conduit coextensive with the length of the main tubular portion through which the waste water passes;
• (b) a tubular boss operatively connected to said main tubular portion;
• (c) a secondary conduit disposed within said tubular boss;
• (d) said secondary conduit having first and second ends, said first end being in communication with said main conduit, and
• (e) means for selectively adjusting said secondary conduit between first and second operating locations;
• (f) said first end of said secondary conduit extending inwardly only a portion of said main conduit, and directed toward said upper inlet when in the first operating location, for channeling only a portion of the waste water from the primary source to a floor drain trap for priming the same;
• (g) said first end of said secondary conduit, when in said second operating location, being directed toward said bottom outlet, and operable for channeling waste water from a secondary source through the waste pipe along with the waste water from the primary source being drained;
• (h) said second end of said secondary conduit, when said secondary conduit is in said first operating location, assuming a position in spaced relation to the position said second end assumes when said secondary conduit is in said second operating location.
