A drain system includes a support frame installable in a tile floor that has a base portion and a wall portion that forms a seat for a drain cover within the support frame. The wall portion defines a cover-facing surface arranged to interface with the drain cover, and a tile-facing surface arranged to face one or more tiles surrounding the support frame. One or more material locking features are on the tile facing surface to help retain grout between the support frame and the surrounding tiles. During installation of the support frame in the tile floor, the vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening.

The present invention relates to a conical filter used to filter storm water being directed into a catch basin and to filter water being pumped from a sediment pond.

A drain guard device for preventing particulates from entering a drain. The drain guard device includes a ring member having an outer circumference and an inner circumference. A groove extends radially along the entire inner circumference. The groove is dimensioned to removably receive a strainer. The ring member is a flexible flat annular ring having a uniform width between the outer circumference and the inner circumference. In use, the drain guard rests over a drain, wherein the lower side of the ring member is configured to frictionally engage an upper side of a surface, such as a floor or sink. The lower side of the ring member is configured to form a suction seal with the upper side of the surface, wherein both the strainer and ring member can be easily removed from the surface by hand when desired.

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 drain assembly comprises a shroud, a shank, and a frame. The drain assembly may further comprise a shim with an angled top surface. The frame may have an angled bottom surface. A rotational orientation of the angled top surface of the shim relative to the shank and a rotational orientation of the angled bottom surface of the frame relative to the shank may be independently adjustable, thereby allowing for the top surface of the frame to be both angularly and rotationally adjusted relative to a central axis of the drain assembly independent of the positional height of the shank. The drain assembly may further comprise a cover having bendable tabs. The bendable tabs may be disposed around a periphery of the cover and may be configured to contact an angled inner surface of an upper bowl of the shroud, such that the bendable tabs bend around the frame, thereby locking the cover onto the frame.

A drain system includes a support frame configured to support and position a drain cover over a drain opening in a tile floor. The support frame has a base portion and a wall portion projecting upwardly from the base portion to define a seat for the drain cover within the support frame. A release surface on the wall portion tapers and slopes inwardly from a top of the wall portion. The release surface is arranged to interface with the drain cover and reduce frictional and shear forces between the drain cover and the support frame during removal of the drain cover from the support frame.

A drain lock sealing apparatus is positioned in a drain pipe for being locked therein and further for sealing the pipe to prevent odors and vermin from coming from the drainpipe into the room. The apparatus includes a grate positioned over the drain pipe, a resiliently deformable sealing ring extending from the grate into the drainpipe, an rigid expander member with an inwardly tapered outer surface extending into the sealing ring, a resiliently deformable frusta-conical member attached to center hub of the expander member so that the peripheral closure edge of the frusta-conical member is in non-fixed normally closed relationship against the circumferential edge of the expander member so that the closure edge opens in response to liquid passing through the grate into the drain and resumes normally close relationship in response to the secession of liquid passing through the grate. A bolt extends through the grate and cylindrical sealing ring and is screwed into the axial hole whereby tightening of the bold compresses the sealing ring axially to deform the cylindrical sealing ring radially into clamping engagement against the interior surface of the drain pipe.

A drain assembly comprises a shroud, a shank, and a frame. The drain assembly may further comprise a shim with an angled top surface. The frame may have an angled bottom surface. A rotational orientation of the angled top surface of the shim relative to the shank and a rotational orientation of the angled bottom surface of the frame relative to the shank may be independently adjustable, thereby allowing for the top surface of the frame to be both angularly and rotationally adjusted relative to a central axis of the drain assembly independent of the positional height of the shank. The drain assembly may further comprise a cover having bendable tabs. The bendable tabs may be disposed around a periphery of the cover and may be configured to contact an angled inner surface of an upper bowl of the shroud, such that the bendable tabs bend around the frame, thereby locking the cover onto the frame.

An expansion ring mountable in a storm drain for supporting a filtering apparatus includes a ring-shaped expansion member having an adjustable diameter which is cut transversely to define two open end portions thereon which face each other and which are separated from each other by a predetermined distance to define a gap therebetween. A wedge assembly is positioned at the gap between the open end portions of the expansion member and is adjustable to increase the diameter of the expansion member. When the wedge assembly is adjusted to increase the diameter of the expansion member, the expansion member tightly engages a side wall of a portion of the storm drain in which the expansion ring is mounted to secure the expansion ring, and a filtering apparatus supported thereby, in a desired position.

A drain system includes a support frame installable in a tile floor that has a base portion and a wall portion that forms a seat for a drain cover within the support frame. The wall portion defines a cover-facing surface arranged to interface with the drain cover, and a tile-facing surface arranged to face one or more tiles surrounding the support frame. One or more material locking features are on the tile facing surface to help retain grout between the support frame and the surrounding tiles. During installation of the support frame in the tile floor, the vertical position of the support frame over the drain opening is adjustable and the support frame does not extend downwardly into the drain opening such that the support frame is floatable over the drain opening for lateral and rotational adjustment of the support frame relative to the drain opening.
