Disclosed is a positive and negative pressure resistant sealing apparatus of a balance shaft two-way valve plate used for a drainage pipeline, which relates to the technical field of sewer line water seal protection. The apparatus comprises: a main body, a pressure conductor and a balance shaft two-way powered valve plate; the main body comprises a pressure conduction cavity and a drainage cavity, the pressure conduction cavity is located on one side of the drainage cavity, and the pressure conductor is arranged in the pressure conduction cavity of the main body. In the present invention, the effects of a pressure conduction membrane, a transmission connecting rod and the pressure conductor make it so that when the pressure at an upper end of a water seal is greater than the pressure at the lower end, a pressure membrane abuts against and holds in place the pressure conductor, causing the pressure conductor to have a downward movement trend, and causing the pressure conductor to push the transmission connecting rod, further causing the transmission connecting rod to abuts against and hold in place a supporting rod, preventing the supporting rod from forming a rotating trend to push the balance shaft two-way powered valve plate, further preventing the balance shaft two-way powered valve plate from driving an opening and closing valve plate to open, and thereby effectively preventing odor from spreading in the sewer pipeline.

Accessory for sanitation facilities, in particular intended for the treatment of a flow of discharge water coming from a sink or similar, comprising a housing which has an inlet region and an outlet region for the water flow couplable to the pipe which exits from the lower part of the sink, a filtering element having been provided in the interior of the housing to allow the passage of the flow and to retain small particles and an endless axis actuatable by way of the rotary actuation means, also having a storage container which is coupled and in communication with the interior of the housing, the storage container being located with respect to the endless axis. In this way, when the endless axis is actuated, the particles or residues accumulated in the filtering element are displaced towards the interior of the storage container.

A drain assembly for a sink has an abutment surface (14) for abutting an underside of the sink around the drain aperture, and a first wall portion (16) circumscribing an upper drain volume (18). A down-flow conduit (20) and an up-flow conduit (24) are delineated by a second and third wall portions (22, 26), one of which has an edge defining a lip (28) between the down-flow conduit (20) and up-flow conduit (24). An outlet (30) is connected to up-flow conduit (24). A removable lower cover (32) attaches to the wall portions so as to complete a flow path from the down-flow conduit (20) to the up-flow conduit (24) so as to form a trap. At least the first, second and third wall portions (16, 22, 26) and the outlet (30) are integrally formed as a unitary body, most preferably by an injection molding process.

A tubular insert is inserted in a tubular P-Trap which comprises a straight inlet section, a U-Bend trap section, and a straight outlet section. The insert has an inner diameter, an outer diameter, and a length such that the length is greater than an inner diameter of the P-Trap. Liquid flow is allowed to pass through the insert but oversized objects, having a maximum size greater than the insert inner diameter of the insert, are prevented from flowing through it. A retractor is used to retract the insert along with the oversized object from the inlet section of the P-Trap.

A toilet fixture is provided including an inlet pipe, a toilet bowl in fluid communication with the inlet pipe, an outlet pipe in fluid communication with the toilet bowl, a jet pipe in fluid communication with the inlet pipe and the outlet pipe, and a removable jet pipe assembly that connects the jet pipe to the outlet pipe. A foreign object strainer may be positioned in-line with the inlet pipe. A flush assembly may also include a flush valve, a vacuum breaker tube in fluid communication with the flush valve, a foreign object strainer in fluid communication with the vacuum breaker tube, and an outlet pipe in fluid communication with the foreign object strainer.

A drain trap adaptor adapted to allow draining of a drain trap and retrieval of a material. The drain trap includes a first drain pipe having an entry portion and an exit portion, a second drain pipe extending from the exit portion and a bore disposed substantially at the exit portion. The drain trap adaptor includes a ball valve having an inlet end and an outlet end, wherein the inlet end is adapted to connect to the bore; and a container adapted to connect to the outlet end of the ball valve. The container is configured to receive the drainage trapped in the drain trap and the material at the bore upon opening of the ball valve such that the drain trap can be drained and the material can be retrieved.
