Overflow Assembly for Bathtubs and the Like

An overflow assembly for facilitating leak testing of a plumbing system that is adapted to be associated with a bathtub, comprising:

• an overflow pipe including an upper and a lower end;
• an elbow between said upper end and said lower end, said upper end having threads and being adapted to fit completely through an overflow port of the bathtub;
• a lip extending radially outwardly from an outer surface of the overflow pipe between said elbow and said upper end that is adapted to engage an outer surface of the bathtub adjacent to the overflow port;
• a nut element associated with said overflow pipe adapted to secure said overflow pipe to an end of the bathtub wherein a wall of the bathtub is positioned between said lip and said nut element, said nut element comprising threads compatible with said threads of said upper end and said nut element having a plurality of lugs extending radially from said nut element;
• a means for preventing fluid flow through said overflow pipe;
• and
• a cap selectively interconnected to said nut element.

An overflow assembly for a bathtub, comprising:

• an overflow port having a flange, said overflow port associated with a threaded portion extending from said flange, said threaded portion adapted to pass through a wall of the bathtub and to be at least partially positioned within the bathtub;
• a means for preventing fluid flow through said overflow port that is associated with said threaded portion, said means for preventing fluid flow sealing an outer end of said threaded portion;
• a nut, having a threaded center opening, threadably mounted on said threaded portion of said overflow port, said nut being adapted to secure said flange to the wall of the bathtub by exerting pressure towards said flange;
• and
• wherein said nut has an outer periphery with a series of radially extending lugs which detachably engage an inner surface of a cap which fits over said nut.

An overflow assembly for a bathtub, which has a bottom and adjacent side and end walls, and an overflow port in one end wall, comprising:

• an overflow pipe having an upper end portion and a lower end portion with an elbow portion positioned therebetween, said upper end portion having threads and defining a fluid inlet;
• wherein said overflow pipe further comprises a lip that extends radially outwardly from an outer surface of said overflow pipe, said lip spaced from said fluid inlet and positioned between said elbow portion and said upper end portion;
• a sealing element associated with said upper end portion that closes said fluid inlet to fluid flow;
• a nut element having threads compatible with said threads of said overflow pipe, said nut element having a series of retention lugs spaced about a longitudinal axis defined by said nut element, there being gaps between successive lugs;
• and
• a cap detachably associated with said series of retention lugs and covering at least a portion of said nut.

An overflow assembly for a bathtub, comprising:

• an overflow port having a flange, said overflow port associated with a threaded portion extending from said flange, said threaded portion adapted to pass through a wall of the bathtub and to be at least partially positioned within the bathtub;
• a nut, having a threaded center opening, threadably mounted on said threaded portion of said overflow port, said nut being adapted to secure said flange to the wall of the bathtub by exerting pressure towards said flange;
• and
• said nut having an outer periphery with a series of radially extending lugs which detachably engage an inner surface of a cap which fits over said nut.
