The present disclosure provides a sump drain apparatus comprising a drain bowl, a ramp connected to the drain bowl comprising an incline plane configured to divert drainage water toward the drain bowl, and an attachment flange connected to the ramp and configured to couple the sump drain apparatus to a roof deck, wherein the ramp is configured to be positioned on top of the roof deck and contain sump insulation beneath the ramp and above the roof deck.

An insert for a rain gutter includes a first portion and a second portion. The first portion is configured to be positioned in the rain gutter and includes a plurality of apertures to allow water to flow from the rain gutter into an interior of the first portion when the first insert is positioned in the rain gutter. The second portion extends downward from the first portion and is positioned in an opening of the rain gutter connected to the downspout. The second portion includes a plurality of extensions separated by one or more slots. The second portion also includes a flange configured to be positioned above the opening of the rain gutter and an interior in fluid communication with the interior of the first portion. The interior of the second portion is configured to allow the water to flow through it and into the downspout.

A cover for a drain. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or skirt portion with a large area and extending outwardly in an arcuate or polygonal configuration and having openings for fluid flow. The lower portion may be oriented at a positive, zero, or negative angle with respect to the horizontal. The lower portion may be wider than a drain body over which the cover is used. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and having openings.

A drain insert assembly is provided for retrofitting or for use with an existing drain bowl received in a roof surface that interconnects with a drain pipe. The drain insert assembly includes a drain insert configured to extend between the roof and the existing drain pipe. The drain insert includes a first, end portion dimensioned for receipt in the existing drain pipe, and a second portion dimensioned to cover an inner surface of the existing drain bowl, and at least one flange extending outwardly from the end portion. An uncured seal material is interposed between the end portion and the existing drain pipe.

A cover for a drain. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower portion with a large area extending outwardly at a small enough angle with respect to the horizontal to allow debris buildup thereon. An upper portion may be connected to the lower end and may be more vertically-oriented than the lower portion. Openings in the upper and lower portions allow for fluid drainage therethrough. Drainage occurs even with debris buildup around or on the cover.

An adjustable roof drain for flat and low pitch roofs includes a basin portion and a telescoping basin extension portion. A compression gasket provides a seal between the basin portion and the telescoping basin extension portions of the roof drain. The shape of the compression gasket causes it to be pushed inwardly when compressed so that it seals against the telescoping extension portion to both seal the extension portion and lock it at a selected height.

The present invention is a roof drain assembly that comprises a dome mounted to a drain body by shock arrestors and a roof clamp that is securable to the drain body. A screen is positioned around the inlet and between the drain body and the dome. The shock arrestors and screen permit the dome to compress against the drain body while simultaneously absorbing the energy from an impact. As the shock arrestors compress, the screen also compresses. The resiliency of the screen and the shock arrestors permit the dome assembly to return to its passive state once the compression force is removed.

A drainage device is provided. The drainage device includes a drainage head having at least one head portion having an internal collection space and provided with at least one through recovery passage, and an attachment sleeve at least partially deformable. The attachment sleeve can be secured to the drainage head and capable of being inserted inside the flow pipe. The drainage device further includes a compression washer attached on the attachment sleeve and a central screw. The central screw can be movable in relation to the drainage head and threadably engaged with the compression washer to obtain, under the effect of a rotation of the central screw relative to the drainage head, an axial movement of the compression washer on the side of the drainage head and an outward radial deformation of the attachment sleeve.

A debris clearing system for clearing debris from a drain strainer includes a base member having at least one attachment coupler configured to removably attach the base member to the drain strainer, a support frame rotatably coupled to the base member, at least one arm assembly coupled to the support frame, a clearing member coupled to a distal end of the at least one arm assembly. The clearing member being adjacent the exterior surface of the drain strainer when the base member is coupled to the drain strainer. The system includes a drive unit coupled to the support frame to rotate the support frame and the at least one arm assembly relative to the base member. The clearing member clears debris from the exterior surface of the drain strainer when the drive unit rotates the support frame and the at least one arm assembly.
