Abstract:
A freeze resistant sanitary hydrant is provided that employs a reservoir for storage of fluid under the frost line or in an area not prone to freezing. To evacuate this reservoir, a venturi is provided that is able to function in hydrant systems that employ a vacuum breaker.
Abstract:
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.
Abstract:
An overflow system in the bathtub has an overflow port and has a drain pipe in connection with the overflow port. A threaded flange has a stub shoulder on one end which is fitted into a circular sleeve on the overflow port. The threaded flange has exterior threads on its outer surface and a thin diaphragm secured to the end thereof opposite to the stub shoulder. A large internally threaded nut is threadably mounted on the outer end of the threaded flange. A decorative cap is frictionally snapped into engagement with protrusions on the outer surface of the nut. The cap can be removed when needed to permit the plumber to gain access to the diaphragm to cut it open for fluid flow after the system has been tested for leaks, or put in place after the cut takes place.
Abstract:
A system for securing a hydrant to a roof of a building is provided that includes a hydrant support that rigidly interconnects to the roof deck. In addition, a method of sealingly interconnecting a standpipe of the hydrant to the hydrant support is provided wherein a plurality of seals are employed. In order to enhance the seal provided between the standpipe and a hydrant support, a boot may be used that covers the interface between the standpipe and the hydrant support.
Abstract:
A waste water insert has a cylindrical wall surrounding a vertical cylindrical bore. A horizontal flange extends outwardly from the upper end of the wall and has a lip formed on its outer periphery. The horizontal flange of the waste water insert is super-imposed over the horizontal flange of a waste water strainer located in a bathtub, sink or the like. The cylindrical wall of the insert extends downwardly through the cylindrical wall of the waste water strainer with the two walls being spaced from each other by virtue of the cylindrical wall of the insert having a smaller diameter than that of the strainer. One or more grooves are within the cylindrical wall of the insert and receive resilient rings that engage the cylindrical wall of the strainer.
Abstract:
An assembly for mounting a hydrant to a roof. The assembly includes a housing that is adapted to fit about a standpipe that is disposed through a roof top. The assembly additionally has a sealing member that is positioned between the housing and the standpipe and a mounting plate that is connected to the housing to mount the hydrant to the roof.
Abstract:
A method of installing a wastewater drain assembly for a bathtub by inserting an L-shaped drain pipe into a drain hole of a bathtub such that an annular flange on the drain pipe rests on a bottom wall of the bathtub. Slideably mounting a lock washer over the drain pipe and threadably tightening the lock washer against a lower surface of the bottom wall of a bathtub. Connecting the drain pipe to a drain system. Testing the drain assembly for water leaks. Finally, installing a drain closure into the upper end of the drain pipe.
Abstract:
An apparatus and method for installing a bathtub assembly where an overflow assembly secured to an overflow port of a bathtub and a drain assembly secured to a drain port of a bathtub are adhesively secured to a T-section by use of an overflow hub and drain hub.
