A bathtub drainage and overflow system assembly is a combination of a one-piece overflow pipe and a waste water drain assembly connected by a T-shaped elbow. The one-piece overflow pipe has an inverted L-shape having an elbow portion. A lip extends radially outwardly from an outer surface of the overflow pipe to engage an outer surface of the bathtub end wall around the bathtub overflow port. A thin diaphragm is used to close the inlet to fluid flow. The waste water drain has an L-shaped drain pipe having an annular flange resting on a bottom wall of the bathtub.

1. An overflow assembly adapted for interconnection to a bathtub, which has a bottom, side walls, end walls, and an overflow port in one end wall, comprising: an overflow pipe with an elbow portion defining an upper end portion and a lower end portion, said upper end portion having an outer end defining an inlet and having threads on an outer surface thereof;a lip extending radially outwardly from said outer surface of the overflow pipe between said elbow portion and said upper end portion and being spaced from the inlet;a sealing element associated with said outer end that closes said inlet to fluid flow;a nut element with a threaded portion that is compatible with said threads associated with said inlet for mounting said nut element to said upper end portion, said nut element having a plurality of lugs extending radially from said nut element wherein said nut element and said plurality of lugs constitute a single-piece unit; anda cap detachably interconnected to at least one of said plurality of lugs and covering the nut. 2. The assembly of claim 1, wherein the overflow pipe and sealing element is of one-piece construction. 3. The assembly of claim 1, further including a washer that cooperates with said nut and said lip to interconnect to said overflow pipe to the bathtub. 4. The assembly of claim 1, wherein said sealing element is a diaphragm that is adapted to be selectively cut to provide a flow path through said overflow pipe. 5. The assembly of claim 1, wherein said sealing element has a diameter that is not less than the diameter of said threaded portion of said overflow pipe. 6. The assembly of claim 1, wherein said sealing element is circular, has a diameter that is not less than the diameter of said outer end of said outlet pipe, and is removable. 7. An overflow assembly adapted for interconnection to a bathtub, which has a bottom, side walls, end walls, and an overflow port in one end wall, comprising: an overflow pipe with an elbow portion defining an upper end portion and a lower end portion, said upper end portion having an outer end defining an inlet, said upper end portion having threads on an outer surface thereof;a lip extending radially outwardly from said outer surface of the overflow pipe between said elbow portion and said upper end portion and being spaced from said inlet;a means for sealing associated with said outer end that closes said inlet to fluid flow;a nut element with a threaded portion that is compatible with said threads of said overflow pipe for threadingly mounting said nut element to said upper end portion, said nut element having a series of retention lugs spaced about a longitudinal axis defined by said nut element, wherein there is a gap between each retention lug; anda cap detachably interconnected to at least one of said series of retention lugs. 8. The assembly of claim 7, wherein said overflow pipe and said means for sealing is a one-piece construction. 9. The assembly of claim 7, wherein said gaps possess an innermost surface having an arcuate shape. 10. The assembly of claim 7, wherein said means for sealing is a diaphragm. 11. The assembly of claim 10 wherein said diaphragm is adapted to be selectively cut to provide a fluid flow path through said overflow pipe. 12. An overflow assembly adapted for interconnection to a bathtub, which has a bottom, side walls, end walls, and an overflow port in one end wall, comprising: an overflow pipe with an elbow portion defining an upper end portion and a lower end portion, said upper end portion having an outer end defining an inlet, said upper end having threads on an outer surface thereof;a lip extending radially outwardly from said outer surface of the overflow pipe between said elbow portion and said upper end portion and being spaced from said inlet;a nut element with a threaded portion that is compatible with said threads of said overflow pipe, said nut element having an outer periphery with a series of radially extending lugs that detachably engage an inner surface of a cap that fits over said nut. 13. The assembly of claim 12, wherein said nut element and said radially extending lugs constitute a single-piece unit. 14. The overflow assembly of claim 12, further comprising a sealing element associated with said outer end that closes the inlet to fluid flow. 15. The assembly of claim 14, wherein said sealing element is a diaphragm that is adapted to be selectively cut to provide a flow path through said overflow pipe. 16. The overflow assembly of claim 12, further comprising a means for preventing fluid flow through said overflow pipe that is associated with said threaded portion, said means for preventing fluid flow sealing said inlet. 17. The assembly of claim 16, wherein said means for preventing fluid flow is a selectively removable diaphragm.
