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 support is configured for installation on a surface and to support one or more floor tiles. The drain support includes a base at least partially defining a channel and an outlet, wherein the base defines a base axis, a support dome coupled to the base, wherein the support dome includes at least one aperture formed therein configured to allow fluid to flow from a position outside the dome into the channel, and a pedestal defining a support surface configured to support one or more floor tiles thereon during use, wherein the pedestal is movably coupled to the support dome.

A combination of a cover plate and a drain, preferably a floor drain is described. The cover plate is provided with first locking means and the drain is provided with cooperating second locking means for releasable connection of the cover plate to the floor drain. The cover plate is a temporary cover plate for use during installation of the drain. The cover plate may be used for a temporary protection of a drain during installation of the drain and for installing and adjusting the inclination of the drain without the need of separate levelling tools. To obtain this the cover plate is provided with levelling means for determining the orientation of the cover plate and thereby also the drain in relation to a horizontal or a vertical plane. The first locking means or the second locking means comprises a weakening arranged such that at least a part of the locking means is preferably damaged when the cover plate is removed from the drain to ensure that the cover is not reused.

A device for preventing drain blockage can include a planar base and an upright vane support rotatably supported on the base. The vane support includes a plurality of curved vanes mounted in a radial configuration thereon. The base includes a plurality of raised portions on an upper surface thereof and a cylindrical flange extending downwardly from a bottom surface thereof. The flange can frictionally engage the inner walls of a drain pipe for draining water from the device. A base insert is housed within a circular recess of the base and rotatably supports the vane support. The vanes each include a lower edge in close proximity to the top surface of the base. When wind, rain, or debris strikes the curved vanes, the vane support rotates, and the lower edges of the vanes sweep away any debris accumulating on the base.

The roof drain overflow cover with sensor cooperatively engages and covers a conventional roof drain cap cover to prevent trash from reaching and clogging the conventional roof basket cover and drain. Accumulating trash builds up on the screen of the overflow prevention device causing a doughnut shaped buoy connected to a trash tray to rise. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the doughnut shaped buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating an overflow sensor and a control module. The control module is in communication with the water flow sensor and includes an indicator which is activated when the water flow sensor detects the detachment of the trash tray from the base indicating a potential flooding situation with the roof drainage system.

A seal assembly, including a first conduit member having a first seat and a second conduit member having a second seat. The second conduit member is coupled to the first conduit member such that the first and second conduit members are movable between at least a rest configuration in which the first and second seats are a rest distance apart, and a compressed configuration in which the first and second seats are held at a compressed distance apart. The compressed distance is less than the rest distance. The seal assembly also includes a flexible seal received between the first and second seats such that the flexible seal is compressed when the first and second conduit members are in the compressed configuration, the flexible seal expanding axially outwards when compressed to engage with an inner surface of a body in which the seal assembly is received.

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 two-stage filtering drain cover that can be retrofitted to an existing, original construction, areaway drain cover. The filtering drain cover of the invention inhibits the accumulation of debris on the existing drain cover, and passage of debris into the drain, and helps to prevent clogs and flooding. The outer cover member of the device is configured with passages that permit liquid flow through the outer cover while filtering larger size debris particles that may be entrained in the passing liquid. A perimeter wall on the outer cover and with similar liquid flow passages stops larger debris from passing the outer cover. An inner filter member fits within the outer cover and is configured with relatively smaller passages to obstruct smaller sized debris that may have penetrated the outer cover from passing into the drain.

A roof drain including a base defining a channel and an axis, a gravel guard coupled to the base and including a plurality of teeth, where the gravel guard defines a plurality of gullets between the teeth, and a dome coupled to the base, where the dome includes a plurality of ribs, where the ribs define a plurality of gaps therebetween, and where each gap is radially aligned with a corresponding gullet.
