Abstract: A plumbing fitting for a drain line of a plumbing system has a fitting body having a fluid inlet, a fluid outlet, and a cleanout port in fluid communication with a cavity defined by the fitting body. A releasable plug is positioned in the plumbing fitting upstream of a strainer body that prevents the releasable plug from passing through the fluid outlet in the released position. The releasable plug may be an expandable plug that is installed upstream of the strainer or may be a closure member that seals the strainer and is removed from the strainer to unseal the drain line. The releasable plug is actuated to a released state from outside the plumbing fitting.

Abstract: A seal for a protrusion from an exterior wall of a structure includes a sheet made from flexible material, the sheet comprising a wall cover portion and a protrusion engaging collar. The protrusion engaging collar extends outward from the wall cover portion and defines a hole. The collar has a first inner perimeter adjacent to the wall cover portion and a second inner perimeter spaced from the wall cover portion. The first inner perimeter is larger than the outer perimeter of the protrusion and the second inner perimeter is equal to or smaller than the outer perimeter of the protrusion. The collar provides a seal around the outer diameter of the protrusion when installed.

Abstract: Flashing for a building profile is formed using a flexible sheet of impermeable material. The flexible sheet has one or more fold lines extending in a first direction and spaced across the flexible sheet in a second direction that is perpendicular to the first direction. The one or more fold lines are defined by an increased flexibility relative to the flexibility of the flexible sheet.

Abstract: A backwater valve has a valve body, and a valve member pivotally movable about a pivot axis between an open position away from the valve body and a closed position covering the valve body. A control linkage is provided with at least one of a float or a counterweight in communication with the valve member via the control linkage to modify operation of the valve member.

Abstract: A method of sealing around a penetration that extends out of a wall of a building with structural members separated by spaces. A weather barrier is installed across the structural members of the wall such that the weather barrier defines a wall surface and the penetration extends past the wall surface. A backer support is installed behind the weather barrier and adjacent to the penetration. The penetration is sealed to the weather barrier by applying a sealing material around the penetration, the backer support being sufficiently rigid to support the weather barrier and the sealing material against pressure applied during installation.

Abstract: A backwater valve has a hollow valve body with an inlet and an outlet and a valve member pivotally movable about a pivot axis disposed above the inlet. The valve member is movable between a closed position covering the inlet and an open position. The valve member has a specific gravity that is greater than water and has a basin that causes the valve member to be buoyant when the basin is filled with air. A releasable latch holds the valve member in the open position and releases the valve member when the valve member pivots to a release position. A rotational stop engages the valve member at a fill position permitting water to overflow into the basin.

Abstract: A flashing hood for utility lines passing through a wall of a building has a plate body with a plate opening surrounded by an enclosed hood body. The bottom of the enclosed hood body has a sidewall with a seal-receiving profile and a cover-receiving profile spaced from the plate body and above the seal-receiving profile. The enclosed hood body has a removable seal that engages the seal-receiving profile, the removable seal having a sealing profile that seals against one or more utility lines when installed. The hood body also has a removable cover that engages the cover-receiving profile and secures the removable seal in engagement with the seal-receiving profile. The sidewall, the removable seal, and the removable cover define an enclosure. When the removable cover and seal are removed, the sidewall defines an access opening that surrounds the plate opening.

Abstract: A backwater valve has a hollow valve body having an inlet and an outlet, and a valve member pivotally movable about a pivot axis disposed above the inlet. The valve member pivots between an open position in which the valve member is away from the inlet and a closed position in which the valve member closes the inlet. A cam is rotatably mounted above the inlet. The cam has a first rotary position in which the valve member is permitted to move to the open position and a second rotary position in which the cam engages the valve member to secure the valve member in the closed position. With the valve member in the open position, the cam pushes the valve member toward the close position as the cam moves toward the second rotary position.

Abstract: A sill pan for a building opening has a bottom plate with a first end, a second end, a front edge and a rear edge. An end wall is located at the first end of the bottom plate and extends substantially away from the first end in a direction that is substantially perpendicular to the bottom plate. The end wall has a front edge and a rear edge that are coplanar to the front and rear edges of the bottom plate, respectively. A front skirt and a rear skirt are connected to the front and rear edges, respectively, of the bottom plate and the end wall. The bottom plate, end wall, front skirt, and rear skirt are vacuum formed as a unitary body from a foldable material. The bottom plate is self-supporting in a no-load condition and conformable to a load applied during installation in the building opening.

Abstract: A weather barrier for a building penetration having opening in a wall of the building and a utility extending through the opening is provided. The weather barrier is made up of a sheet of flexible, weatherproof material, having a utility receiving chamber surrounded by a planar, building engaging section. The utility receiving chamber has a sidewall that extends perpendicularly to a plane defined by the building engaging section. A structural collar is sized and shaped to be friction fit within the sidewall of the utility receiving chamber, and is movable along the sidewall upon application of a sliding force. The structural collar has an inner circumference that receives an outer circumference of the utility.

Abstract: A combination of a junction box, a cover plate, and a weather barrier is provided. The junction box has a sidewall, an open end, and a closed end. The cover plate is removably connected to the junction box, and is sized to cover the open end of the junction box. The weather barrier has a non-permeable sheet with a wall cover portion that surrounds a flange that defines a junction box receiving area. The flange protrudes from a first face of the wall cover portion and terminates in a top peripheral edge. The junction box is positioned within the junction box receiving area, the flange surrounds the junction box, and the top peripheral edge extends toward the open end of the junction box. The cover plate engages and forms a seal with the top peripheral edge of the flange when the cover plate is connected to the junction box.

Abstract: There is provided a weather barrier for an opening in a wall of a building and a utility that passes through the opening. The weather barrier has a sheet of flexible and water resistant non-elastic material, which has an outer perimeter and an inner perimeter that defines a central passage that is larger than an outer diameter of the utility. A sheet of elastomeric material is sealably attached to the sheet of non-elastic material at the inner perimeter. The sheet of elastomeric material extends inward from the inner perimeter and defines a central opening that is smaller than the outer diameter of the utility. When the sheets of non-elastic and elastomeric material are disposed in a flat position, the sheet of non-elastic material defines a plane and the sheet of elastomeric material is parallel to and in line with the plane of the sheet of non-elastic material.
