Non-metal pipe couplings, namely, saddles that make lateral connections with sewer pipes

Abstract

Our valve device, which is used to purge air from a plumbing system, includes a unitary, elastomeric body comprising top wall, a circumferential wall connected to the top wall, and a housing with a cavity that is accessed through a pair of ports. A closure element is moveably disposed within the cavity and responds to fluid entering one port to close the other port. An adjustable strap detachably wrapped around an exterior of the circumferential wall holds our device securely to an open end of a riser conduit of the plumbing system during testing for leaks. The circumferential wall has at least two wall sections of different diameters to accommodate different sized conduits.

Abstract

A coupling used during testing of a water line including an upstream pipe and a downstream pipe connected by the coupling. A removable barrier disk prevents water from flowing through the connected pipes until after testing, when the disk is then detached from the body member of the coupling. A piercing assembly interacts with a groove near the perimeter of the disk to initiate a tear that propagates along the groove as the disk is pulled away from the body member of the coupling. The piercing assembly is attached to the disk by a fulcrum element offset with respect to a center of the planar disk.

• F16L 55/12 - Means for stopping flow in pipes or hoses by introducing into the pipe a member expandable in situ
