A drain assembly for use with a plumbing system. The drain assembly includes a base, a dome, and a drain attachment. The base includes a first end, a second end opposite first end, and defining a central axis. The base at least partially defines a channel open to both the first end and the second end. The channel has an inlet at the first end of the base. The dome is coupled to the base and at least partially encloses the inlet. The drain attachment includes a body and a plurality of baffles. The body extends parallel to the central axis and includes a first end and a second end opposite the first end. The body also defines a passageway open to both the first end and the second end. The plurality of baffles extends outwardly from the body.

The invention refers to a drainage system (100), in particular a roof drainage system, comprising an outlet member (10) and a flow restrictor (20), whereby the flow restrictor (20) is situated above the outlet member (10). The flow restrictor (20) comprises a contact portion (22) and the outlet member (10) comprises a flange portion (12), whereby a first sealing member (30) is arranged on and/or along the flange portion (12) of the outlet member (10) and a second sealing member (40) is arranged at the contact portion (22) of the flow restrictor (20).

The present disclosure provides a sump drain apparatus comprising a drain inlet and a ramp coupled to the drain inlet comprising an incline plane configured to divert drainage water toward the drain bowl, wherein at least a portion of the ramp is configured to be positioned on top of a roof deck.

The drainage device 10 comprises: a drainage head 24 internally delimiting a collection space 34 and provided with at least one through recovery passage 36, 38, an attachment sleeve 26 at least partially deformable, secured to the drainage 24 and capable of being engaged inside the flow pipe 20, a compression washer 28 attached on the attachment sleeve 26, and a stressing element 30 movable in relation to the drainage head 24 and cooperating with the compression washer 28 to obtain, under the effect of a movement of said stressing element relative to the drainage head, an axial movement of the compression washer 28 on the side of the drainage head and an outward radial deformation of the attachment sleeve 26.

An apparatus for and method of diverting water is provided. The apparatus includes a contoured bottom configured to engage a roofing surface, a backwall extending from the contoured bottom and first and second sidewalls extending from the contoured bottom. The method involves using the apparatus to engage a roofing surface, receive a flow of water, direct the flow of water, and drain the flow of water through an opening.

The sealing device for construction comprises a duct and a linking member mounted around and rigidly connected to the duct, wherein the duct comprises: an axial main portion around which the linking member is mounted, a radial bead formed on the main portion and extending radially outwards, and a distal end portion extending the main portion radially outwards and which is axially facing the bead to form therebetween an outwardly radially open annular mounting slot, the distal end portion extending radially beyond the bead, the main portion, the distal end portion and the bead of the duct being made of one piece, the linking member being mounted in the mounting slot and gripped axially between the bead and the distal end portion of the duct.

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 apparatus (1), comprising cover plates (2) continuing in a position of use in a common plane and in at least one row, is formed in a mutual edge-side contact region (3) through overlapping and in a rainproof manner, such that edges (5) running parallel to each other and spaced apart on each cover plate (2) are designed differently (6), and the top side (7) of the cover plate (2), a continuing web (8) and a rain gutter (9) under said web (8) are arranged on a first edge (5), wherein said rain gutter belongs to the same first edge (5). If necessary, penetrating rain water (12) can be caught in the rain gutter (9) by overlapping edge-side webs (8) in the position of use.

The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.
