A drain assembly comprises a drain pan, a trim member, and a drain cover. The drain pan has a base and a pan sidewall, and the trim member has a trim sidewall. The pan sidewall, at least a portion of the upper surface of the base, and the trim sidewall define a drain channel therebetween. The drain cover defines a plurality of apertures and is positionable above the drain pan. The trim member is configured to transition between a first position and a second position. In the first position of the trim member, the drain channel has a first width that extends in a transverse direction. In the second position of the trim member, the drain channel has a second width that extends in the transverse direction. The first width is different than the second width.

Systems and methods of installing a fixture into a material are provided. The fixture includes a body and a cover assembly that is removably coupled to the body and configured to move relative to the body once the body has been secured within the material. The cover assembly includes a movable component configured to aid removal of the cover assembly.

Provided herein are embodiments of a flood prevention system. The flood prevention system may include a water line, a sewer line, and at least one floating switch sensor. The water line and sewer line may be connected to a plumbing fixture. The floating switch sensor may be installed within the sewer line and be connected to a solenoid valve.

A drain assembly includes a drain body, barrel, plug, and sleeve. The drain body has an interior surface defining a channel along an axis and having interior threads thereon. The barrel has a central body having an upper end, with a flange extending radially outward therefrom and defining a landing surface. The central body has opposed exterior and interior barrel surfaces having exterior and interior threads, respectively. The interior barrel surface defines a channel alignable with the axis. The exterior threads are engageable with the drain body interior threads for axially adjusting the barrel relative to the drain body. The plug has a top surface and an outer body extending axially downward to a stop surface. An inner portion of the outer body extends axially below the stop surface and has external threads engageable with the barrel interior threads. The sleeve is sealingly receivable between the stop and landing surfaces.

A frame (4) is designed to be inserted into a channel body (3) of a floor drain (1), the channel body forming an outflow channel (8) and having an outflow opening (9). The frame includes at least substantially vertically extending side walls (11) arranged in the form of a frame and which together form a receiving opening (12). An at least substantially horizontally extending frame flange (13) adjoins the upper edges of the side walls (11) and surrounds the receiving opening (12) in a frame-like manner. Projections (14) projecting into the receiving opening (12) are provided on opposite side walls (11) and form a receiving framework to receive and support a cover (5) to be inserted into the frame (4) from above, characterized in that the projections (14) are provided in the form of indentations.

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 strainer assembly for use with a floor waste receptor having vertical walls and a floor forming a well into which liquid waste material can be collected and directed toward a well discharge opening and then into a drain pipe, the vertical walls having an outer flange extending outward from the vertical walls at a position below the top surface formed by the vertical walls, and an inner ledge formed below the top surface, and the floor shaped to form a ledge around the drain opening, comprising: a well discharge opening strainer assembly; a basket strainer sized to fit in the well and over the well discharge opening strainer assembly and sit on the floor ledge, the basket strainer provided with openings sized to permit liquid water matter of a second predetermined size to move from the floor receptor well through the basket strainer and into the well discharge opening strainer assembly, and a grate strainer sized to sit on the interior ledge.

A method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes (at the first location) preparing multiple panels of polymeric concrete material by filling one or more molds with a slurry or liquid polymeric concrete material and after time allowing the material to cure and harden. The mold can have a cavity that is lined with a release material. At the first location, one or more of the panels can be adhered to the bottom wall and side walls of each concrete section preferably using an adhesive. After adhering of the panels to the concrete sections, the concrete sections can be transported from the first location to a second location that is remote from the first location. At the second location, the concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout is preferably field applied to the connections at the second location.
