The present invention relates to a plumbing assembly for connecting a discharge connection of a fixture to a waste outlet, the assembly comprising a substantially rigid conduit trap portion (whether the trap portion forms a part of an S, P, U or J shaped conduit bend). The rigid conduit trap portion including an inlet and an outlet, and a substantially conformable or flexible conduit portion connectable to the rigid conduit trap portion at either of i) the rigid conduit trap inlet, or ii) the rigid conduit trap outlet. The rigid conduit trap portion and conformable or flexible conduit portion when assembled providing for a complete trap assembly.

A disposable oil and grease trap for containing and disposing of grease, oil, fat, etc. produced by cooking. The disposable oil and grease trap generally includes a rim adapted to rest above a surface of a sink, the rim having a bottom, an upper surface, and a central opening. The trap may also include a trap element sized and shaped to extend into a sink drain below the surface of the sink, the trap element being secured to the bottom of the rim such that the rim suspends the trap element. The rim may also include an adhesive on its upper surface, wherein the rim is foldable such that the adhesive on a first portion of the rim contacts the adhesive on a second portion of the rim to contain a substance, such as a waste material, within the trap element.

The present invention relates to a floor drain for draining water from a walk-in floor into a waste water pipe, with an inlet channel socket, a first receiving body for the inlet channel socket, a second receiving body for the first receiving body and a drain housing following the second receiving body in the water drainage direction, which is preferably designed as an odor trap, wherein the first receiving body has a bowl-shaped section, to the outer edge of which a flexible sealing mat is connected in a liquid-tight manner and the bottom of which passes into a first drain connection piece which can be inserted into the second receiving body, wherein the second receiving body has a bowl-shaped section on which an outwardly projecting flange is integrally formed or attached, and wherein the bowl-shaped section of the second receiving body passes into a second drain connection piece.

A method of retrofitting a drainage pipe is disclosed. The method provides removing a pre-existing bathtub drain of a pre-existing bathtub drainage system to expose the concrete-encased drainage pipe, attaching a gasket to an exposed end of the concrete-encased drainage pipe, attaching a drain body to the gasket, attaching a strainer to the drain body, and attaching the drain body to the concrete-encased drainage pipe via the gasket. The drain body and gasket create a water-tight seal with and between the concrete-encased drainage pipe when attached. The method enables a user to convert a pre-existing bathtub drainage pipe to a shower drainage pipe without the added necessity of digging into the concrete surrounding the pre-existing drainage pipe below the pre-existing bathtub drain in order to place a small piece of modern piping material and a secure fastener below the body of the shower drain.

A quick-assembly deodorant drainer for washbasin, includes a drainer body having a mounting portion, a connecting portion and a sewer pipe. The mounting portion is mounted in a water outlet of the washbasin and extends downward, the connecting portion is mounted at a lower end of the mounting portion, and the connecting portion includes a deodorant anti-overflow device. The deodorant anti-overflow device includes a cylinder and a sealing cover, the upper end of the cylinder is open and a water-flow hole is disposed at the lower end thereof, and a cylindrical convex portion is disposed at an inner bottom portion of the cylinder and extends upwardly. The convex portion has a through hole, and the sealing cover is disposed at the bottom of the cylinder through a fixed shaft connected to the sealing cover. The upper end of the fixed shaft has a sleeve sleeved over the convex portion.

A plumbing drain trap treatment mixture is disclosed. The mixture is poured into a plumbing drain trap to form a layer of the mixture that floats on top of the water in the trap. The mixture layer forms a boundary to prevent evaporation of the water from the trap, thereby maintaining the water in the trap to prevent sewer gas infiltration and pest infiltration to the building. The anti-pest and antimicrobial properties of the mixture may serve to further prevent migration of pests from the sewage drain beyond the trap through the plumbing trap and into the building and/or to protect the barrier itself from microbial infestation. A method of use of a treatment for a plumbing drain trap is also disclosed.

The invention relates to an odor trap device for sanitary fixtures, in particular urinals, having a drainage element which has a pipe section, the pipe section defining a sealing wall, having a sealing diaphragm which is in sealing contact with the sealing wall in a closed position and is pushed away from the sealing wall into an open position when fluid, such as urine, is present, and having a holder for mounting the sealing diaphragm relative to the sealing wall. In order to minimise the risk of odor formation in an odor trap device of this kind and also to reliably discharge small quantities of urine or liquid present, it is provided, in accordance with the invention, that the sealing diaphragm is fixed on the holder, the holder being supported below the sealing diaphragm.

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.

A drain pipe assembly for installation of a basin includes: a drain pipe which is inserted in a drain port formed in a base of basin and has a flange of which an upper end is caught by the drain port; and a fastening member which fixes the basin against the flange, wherein the fastening member pulls the drain pipe, which is exposed below the basin, in a downward direction, to upwardly press the basin, thereby fastening the basin and the drain pipe.
