Method and associated apparatus for assembling and testing a plumbing system
A system is provided for enhancing the interconnectability of a bathtub to a plumbing system. More specifically, provided is a flexible conduit and an overflow assembly that allows for a portion of the overflow assembly to be easily located with the wall of a bathtub. The flexible conduit provided allows for adjustability of the conduit to the openings of the bathtub. In addition, provided are methods and apparatus that facilitate testing of a plumbing assembly. Finally, an apparatus and methods are provided that protect portions of the finished bathtub assembly to decrease in the need for replacing said hardware. It is envisioned that aspects and inventions disclosed herein can be used in conjunction to facilitate the interconnection and protection of hardware associated with a bathtub.
1. A plumbing system for interconnection with a bathtub that has an overflow port and a drain port, comprising:
an overflow assembly that includes:
an overflow pipe with an elbow portion defining an upper end portion, which is adapted for interconnection with the overflow port, and a lower end portion, which is adapted for interconnection with a wastewater drain assembly, 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 said 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; and
a waste water insert for selective engagement with a strainer that is associated with the wastewater drain assembly.
2. The system of claim 1 wherein said overflow assembly further comprises a means for preventing fluid flow through said overflow pipe.
3. The system of claim 2 , wherein said means for preventing fluid flow is a selectively removable diaphragm.
4. The system of claim 1 , further comprising a washer associated with said upper end of said overflow pipe such that said washer is adapted to be positioned between the wall of the bathtub and said nut element.
5. The system of claim 1 wherein said waste water insert has a groove that receives a resilient ring.
6. A plumbing system adapted for interconnection with a bathtub that has an overflow port and a drain port, comprising:
an overflow pipe with:
an elbow portion defining an upper end portion, which is adapted for interconnection to the overflow port, 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;
a cap detachably interconnected to at least one of said plurality of lugs and covering said nut element; and
a wastewater drain assembly adapted for interconnection to the drain port and to the lower end portion of said overflow pipe, said drain assembly including a drain pipe having an upper end with an annular flange for resting on a bottom wall of the bathtub, and a means for locking slidingly received by, and threadingly engaged, to said drain pipe, wherein tightening said means for locking against an outer surface of the bottom wall of the bathtub secures said wastewater drain assembly to the bathtub.
7. The system of claim 6 , wherein said overflow pipe and said sealing element is a one-piece construction.
8. The system of claim 6 , further including a washer that cooperates with said nut and said lip to interconnect said overflow pipe to the bathtub.
9. The system of claim 6 , wherein said sealing element is a diaphragm.
