Abstract: A window well drainage system and method are provided. According to an aspect, the system comprises a window well base defining a window well cavity having a lowest end, a main drainage conduit opening in the window well cavity, a window well screening component engageable to cover the window well cavity and a drainage conduit screening component engageable to cover the upper port of the main drainage conduit, the window well screening component and the drainage conduit screening component being spaced apart from one another when engaged. According to another aspect, the system further comprises at least one secondary drainage conduit connectable to the main drainage conduit, said at least one secondary drainage conduit extending from the main drainage conduit to the foundation drain when connected to the main drainage conduit.

Abstract: A P-trap device for plumbing drainage systems is shown. The device has a first tubing element having a pipe attachment bell at one end and a first coupler portion at the other end and a second tubing element having a pipe attachment bell at one end and a second coupler portion at the other end, wherein said first and second coupler portions are sized and shaped to be coupled together. The device further has at least one of said first or second tubing element being a generally unshaped section sized and shaped to trap water therein. A connector to releasably couple said first and second coupler portions together is included, the connector including a sealing gasket. The sealing gasket, first coupling portion and second coupling portion are sized and shaped to permit the first and second coupler portions to be coupled together over a range of angles to form a leak resistant joint without introducing stresses into the plumbing system.

Abstract: An emergency backflow system includes a drain bowl and a holding tank fluidically connected to a utility sewer line. The holding tank is connected to the sewer line via a drain line, and the drain line can be fluidically separated from the drain bowl by a conduit having a float ball therein. The holding tank has a large capacity relative to the drain bowl and thus can accommodate large overflow situations which would otherwise overwhelm the drain bowl.

Abstract: A method for installing plumbing fixtures in a multi-story building having a waste stack includes a stop valve between the waste output of each fixture and the waste stack, the valve allowing the waste water to flow from the fixture toward the waste stack, but preventing flow from the waste stack back into the plumbing fixture. The valve has a cylindrical body, a lower assembly and an upper assembly, which together form a water-tight structure, with threaded outlets in each assembly. Within the body there is suspended a stop ball having a diameter larger than that of the ball seat in the upper outlet. When water attempts to back up from the waste stack in the direction of the stop valve, the ball is forced against the upper seat and blocks the water flow.

Abstract: A flood control valve assembly designed to be removably connected to the outer or exposed end of a drain pipe and structured to allow water to enter the drain pipe in the conventional fashion but prevent water from issuing from the open, outer end of the drain pipe such as during heavy rain and/or flood conditions. The valve assembly includes a tubular housing having a hollow interior and oppositely disposed open ends which define a path of liquid flow through the housing. The housing is removably secured on the interior of the drain pipe immediately adjacent to the open end thereof and further includes a buoyant material valve member movably mounted within the housing and being positionable into an out of a closed position relative to a valve seat secured adjacent to the outer end of the housing dependent upon the direction of water flow through the housing.
