A sink strainer basket includes a strainer body and an odor prevention arrangement. The odor prevention arrangement includes a drain regulator and a filtration handle. The drain regulator is provided on the strainer body to fully occupy a drainage opening. The drain regulator includes a main drainer body having a sewage passageway, and a blocking assembly movably mounted on the main drainer body to normally close the sewage passageway. The filtration handle extends from the drain regulator to be supported in a drainage cavity. When liquid and larger items are drained in the sink strainer basket, the larger items are filtered by the filtration handle, while the liquid is allowed to pass through the filtration handle to push the blocking assembly to open for draining of the liquid through the sewage passageway.

The invention relates to a siphon arrangement (1) comprising a housing (2) with an inlet connection piece (3), an outlet connection piece (4), and a siphon seat (5) arranged between the inlet connection piece (3) and outlet connection piece (4), and a siphon element (6) arranged in the siphon seat (5), said siphon element having a siphon portion (7) and an inlet (8) facing towards the inlet connection piece (3) and an outlet (9) leading to the outlet connection piece (4). Water can be guided from the inlet connection piece (3) via the inlet (8) into the siphon portion (7) and from the outlet (9) to the outlet connection piece (4). The siphon element (6) is movable, in particular pivotable, in the housing (2) from a use position into a maintenance position, and when in the maintenance position can be removed, in particular pulled out, from the housing.

A hybrid flushing system for water free urinals is presented with a housing having a wall portion forming a cavity for receiving a cartridge. The housing also includes a flushing fluid inlet portion for receiving a flushing fluid and a flushing fluid directing portion configured to direct the flushing fluid. A cartridge for installation into a housing is presented, including a cartridge wall, a flushing fluid receiving portion and a flushing fluid directing portion to direct flushing fluid received to any portion to clean areas of the housing, the cartridge, and connected plumbing. Steps for cleaning a hybrid flushing system are presented with an act of directing a flushing fluid into an area, where the area is one of a cartridge for a hybrid flushing system, a housing for a hybrid flushing system, and a plumbing system connected with the hybrid flushing system.

A waterless urinal cartridge, for waterless urinals, includes a housing and a cover. The housing includes a waste reservoir configured to hold a predetermined volume of wastewater, and a drainage aperture configured so that an amount of wastewater exceeding the predetermined volume of wastewater flows through the drainage aperture to exit the housing. The cover is coupled to the housing and includes a sealing fluid reservoir having walls that define the waste reservoir and the drainage aperture, the walls of the sealing fluid reservoir form a containment perimeter with an open bottom so as to contain a sealing fluid floating on top of the predetermined volume of wastewater, and a plurality of fluid passages direct wastewater from the fluid bowl to the sealing fluid reservoir. The waste reservoir includes a fluid flow control feature that restrains wastewater movement within the waste reservoir in response to a change in vehicle dynamics.

There is an inflow pipe and an intermediate pipe and an outflow pipe forming a passageway there through. The intermediate pipe has an internal surface with a radius of curvature. The outflow pipe is coupled to the intermediate pipe. There is a baffle located within the passageway. The baffle has a lower extent which is a second distance from the first radius of curvature of the internal surface of the intermediate pipe. The second distance is less than the first distance of the radius of curvature of the intermediate pipe.
