ABSTRACT:
A multi-piece waste and overflow unit is used with a bathtub to remove waste water via the overflow drain hole, bottom drain hole, or both holes of the bathtub. The multi-piece waste and overflow unit includes a bottom connector and overflow connector. Both connectors comprise a tubular member, a flange extending radially outwardly with respect to the tubular member, and a frustoconical connector between and connecting the tubular member and the flange. The flanges have a channel formed thereon to receive leakproof adhesive for connecting the connectors to the bathtub respectively. The multi-piece waste and overflow unit also utilizes elbows, T-joints, and conventional pipes for connecting the bottom and overflow connectors.
