  • Patent number: 10190306
    Abstract: An anti-oscillation valve for and in a trap primer to restrict the flow of water from the supply line to an upper chamber of the trap primer and to facilitate the flow of water from the upper chamber to the supply line. The anti-oscillation valve having a body with a water supply bore provided therethrough. The bore includes portions defining an inlet and an outlet. First and second bore shoulders are formed in the bore. A filter screen is retained in engagement with the first bore shoulder. An anti-oscillation valve disc freely rests on the second bore shoulder and is retained between the first bore shoulder and the second bore shoulder. The anti-oscillation valve disc includes a valve disc orifice defined through and communicating the inlet with the outlet.

  • Patent number: 10066378
    Abstract: A method for distributing water from a trap primer to at least one trap. The method includes providing a trap primer having an upper chamber separated by a flexible diaphragm from a lower chamber, and having a resilient gas enclosure located in the lower chamber. Water is provided to the trap primer at a line pressure charging the upper and lower chambers. As a result of a reduction in line pressure, the diaphragm is disengaged from a valve stem opening an orifice and causing the flow of water from the lower chamber to at least one trap.

  • Patent number: 9708808
    Abstract: An embodiment providing one or more improvements includes a trap primer with upper and lower chambers separated by a flexible diaphragm which also interacts with a valve stem to start and stop the flow of water from the trap primer to the trap(s). The lower chamber contains a polymeric foam medium such as a foam ring containing closed cells containing gas or gases. In use, equilibration of water pressures in the upper and lower chambers causes distortion of the foam ring, resulting in equilibration of the gas pressure in the closed cells with that of the chambers. A decrease in line water pressure causes water from the lower chamber to be emitted into the traps.

  • Patent number: 6752167
    Abstract: The wall hydrant is automatically draining, providing freeze resistant, and includes protections against contamination of a building's potable water supply from the backflow of water in an attached hose. In particular, a dual check hose connection backflow preventer provides protection against back pressure from a hose fill of water which is elevated 10 feet. In addition, protection is provided from back siphonage due to a reduction of pressure in the potable water system within the building. Finally, a biased open atmospheric vent is located between the two independent checks to further assure the protection against backflow from the hose to the potable water system.
