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 valve assembly for purging a gas from a conduit system is disclosed. The valve assembly is comprised of a housing defining an interior volume. The housing additionally comprises an inlet port and an outlet port in fluid communication with the interior volume. A buoyant valve member is provided within the interior volume and is adapted to seal the outlet port as the interior volume fills with a fluid such as water. The input port is sealably affixed on a riser such that fluid flow from the riser is directed into the interior volume of the housing. Air entering the interior volume is directed around the valve member and exits the housing through the outlet port. As the air is purged from the system, fluid, such as water, enters the interior volume, causing the valve member to rise. As water reaches the outlet port, the valve member forms a watertight seal, preventing water flow out of the outlet port.
