A device used to conceal at least a portion of a wastewater strainer associated with a bathtub. More specifically, a plate having an opening therethrough is used to overlap a flange of the wastewater strainer wherein the opening in the plate generally coincides with an opening in the wastewater strainer so that the bathtub drain is unobstructed. The plate may include a downwardly extending lip to help facilitate orientation onto the flange of the wastewater strainer. The plate conceals the wastewater strainer, thereby facilitating reconfiguration of a bathtub as the existing wastewater strainer need not be removed and the plumbing system retested.

An article, a container, and a method for disposing of fat, oil, and/or grease (FOG). The article may include a top portion including a top opening and a perimeter rim, and a body portion connected to and below the top portion having; a continuous FOG-impermeable membrane and upper and lower body portions. The body portion may include a body middle surface dividing upper and lower body portions and may be placed on at least a portion of a surface. The lower body portion may be sized to fit within a drain. The container may include an integrally formed continuous outer shell including a partially hollow interior, a top part having a top opening, and liquid impermeable bottom and upper parts, and a middle part dividing the top and bottom parts and including at least one middle edge for placement on a first surface.

The improved urinal apparatus is configured for insertion in an outlet of a urinal. The urinal apparatus includes a hollow body defining an upper housing and a clamp ring/lower housing. The upper housing provides an open chamber configured to receive and retain a consumable detergent/malodour counteractant and the clamp ring/lower housing is configured to support and retain a resealing valve, which is operable to allow flow of fluid, such as urine, from above, but is operable to prevent backflow from below the resealing valve. The urinal apparatus also includes a consumable cap element, which includes an axial opening at least partway through, wherein the opening is configured to receive at least part of the upper housing. A body of the cap element comprises a plurality of radially extending fins. One of the upper housing or the consumable cap element comprise an upper member comprising an array of holes, which facilitate fluid flow and insertion and extraction of the urinal apparatus as a unit.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle separator.

This specification describes an intake filter for use, for example, in a system that collects greywater from baths or showers for re-use in toilet flushing. The intake filter provides essentially dead-end filtration. An influent by-pass may be provided, but the filter is cleaned as required to reduce use of the by-pass. Cleaning is performed when permeability of the filter declines. An upstream sensor may be used to detect the permeability of the filter. In one cleaning method, flowing water, optionally with air, is used to backwash the filter. The impulse of the flowing water also moves one or more valves to direct backwash water to a sanitary drain. For example, pumped effluent may impinge against a first flap to close an effluent drain, the first flap being mechanically linked to open a flap covering the sanitary drain.

A method for releasably securing a sink strainer in a drain hole of a sink by providing a lock nut having a split defined by a pair of opposed surfaces and a locking system comprising a pair of opposed tabs attached to the outer surface of the lock nut with one tab on one side of the split having a threaded hole spaced perpendicularly with respect to the opposed surfaces for receiving a threaded fastener and a second tab attached to the outer surface of the lock nut on the opposite side of the split in opposed spaced relationship to the first tab. The second tab having a hole in axisymmetric spaced relationship to the threaded hole with a diameter of sufficient size to allow a threaded fastener to pass therethrough, and a threaded fastener positioned within the axisymmetric spaced hole and arranged to pass through the hole in the second tab and securely engage the threaded hole in the first tab. When engaged, the threaded fastener holds the opposed surfaces in mating relationship during normal use, and when removed, provide for the lock nut to release from its position in response to application of an external force.
