Abstract
A temporary closure for a bathtub overflow port, comprising placing on the outer end of a drain pipe extending through the overflow port a solid cap threaded on the outer end, with or without a sealing element on its inner surface; a cap with an outer face with an aperture thereon covered by a sealing diaphragm, or a solid plug screwed into a threaded interior of the outer end of the drain pipe.
Claims5
An overflow system for a bathtub which has a bottom, and adjacent side and endwalls, a drain port in the bottom, and overflow port in an endwall, with said overflow port being in communication with a vent pipe, comprising,
- a drain pipe adapted to be in communication with said drain port and said overflow port,
- said drain pipe having an inverted L-shape, including a horizontal leg extending into and through the overflow part of the bathtub, and a vertical leg extending downwardly for connection to a fluid drain system,
- threads on the horizontal leg extending through the overflow port, and
- a cap threadably mounted on an end of the horizontal leg extending through the overflow port,
- the cap being of a material capable of sealing and closing the end of the horizontal leg when threaded against the end thereof.
An overflow system for a bathtub which has a bottom, and adjacent side and endwalls, a drain port in the bottom, and overflow port in an endwall, with said overflow port being in communication with a vent pipe, comprising,
- a drain pipe adapted to be in communication with said drain port and said overflow port,
- said drain pipe having an inverted L-shape, including a horizontal leg extending into and through the overflow part of the bathtub, and a vertical leg extending downwardly for connection to a fluid drain system,
- threads on the horizontal leg extending through the overflow port, and
- a cap threadably mounted on an end of the horizontal leg extending through the overflow port,
- the cap has a circular planar end with a perimeter terminating in a threaded annular flange for interconnection with the threads on the horizontal leg;
- a circular sealing element on a face of the circular planar end of the cap being adjacent the end of the horizontal leg to seal the cap to the end of the horizontal leg.

- a drain pipe adapted to be in communication with said drain port and said overflow port,
- said drain pipe having an inverted L-shape, including a horizontal leg extending into and through the overflow part of the bathtub, and a vertical leg extending downwardly for connection to a fluid drain system,
- and a solid plug threaded into interior threads of the horizontal leg extending through the overflow port to close the end of the horizontal leg.
An overflow system for a bathtub which has a bottom, and adjacent side and endwalls, a drain port in the bottom, and overflow port in an endwall, with said overflow port being in communication with a vent pipe, comprising,
- a drain pipe adapted to be in communication with said drain port and said overflow port,
- said drain pipe having an inverted L-shape, including a horizontal leg extending into and through the overflow part of the bathtub, and a vertical leg extending downwardly for connection to a fluid drain system,
- threads on the horizontal leg extending through the overflow port, and
- a cap threadably mounted on an end of the horizontal leg extending through the overflow port,
- the cap having an opening in its circular planar end, with a thin sealing membrane secured to the cap and extending over the opening in the circular planar end.
