摘要： 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.

摘要： 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.

摘要： An embodiment includes a drain pipe waste water closure protection device which allows passage of fluids through a drain into a pipe waste water closure and a waste water pipe while preventing backflow of fluid or gas from the waste water pipe and pipe waste water closure, as well as preventing evaporation of a water-containing pipe waste water closure located below the drain pipe waste water closure protection device in the waste water pipe. Embodiment drain pipe waste water closure protection devices are easily installed in existing or new drains. Embodiments have two radial disc seals which insure a strong seal between the drain pipe waste water closure protection device and the drain wall. Embodiments include a reinforcing band embedded below the radial disc seals which prevents failure of the radial disc seals.Embodiments include a quadruple pressure accumulating seal which protects against the flow of gas or fluid from the waste water pipe.

摘要： An embodiment wall hydrant includes a reservoir, conduits containing an operating rod assembly and a service rod assembly, and a fluid outlet with a hose connector. The service rod assembly allows water supply to the hydrant to be shut-off from the front of the hydrant which allows servicing of the hydrant without requiring water shut-off to all or a portion of the water supply to the building. Embodiments include a vacuum relief dual check valve assembly at the fluid outlet which prevents backflow of water into the hydrant. Embodiments include a box which protects the hydrant controls.
