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 pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.

A plumbing trap assembly for integrating a plumbing trap into a variety of plumbing geometries includes a plumbing trap that has an inlet and an outlet for plumbing into an existing sewer system of a building. The plumbing trap is curved between the inlet and the outlet to trap water for inhibiting back flow of sewer gasses through the plumbing trap. The plumbing trap has a plurality of threaded sections thereon. The threaded sections are spaced apart from other thereby facilitating the plumbing trap to be cut between a selected pair of the threaded sections. In this way the plumbing trap has an adjustable length to facilitate the plumbing trap to be integrated into a variety of plumbing geometries.

The object of the present invention is to provide a washdown flush toilet which can maintain effective waste discharging performance even with a relatively smaller amount of flush water.

The present invention is a washdown flush toilet including: a bowl part configured to receive waste, and a water discharge trap conduit connected to a lower portion of the bowl part. The water discharge trap conduit includes: an inlet pipe part whose one end is continuous or connected to the lower portion of the bowl part; a trap ascending pipe part whose one end is continuous or connected to the other end of the inlet pipe part and which forms an ascending flow channel; and a trap descending pipe part whose one end is continuous or connected to the other end of the trap ascending pipe part and which forms a descending flow channel. With regard to a cross section perpendicular to a flow direction of the ascending flow channel, a portion on a downstream side of the ascending flow channel is provided with an enlarged part which has a cross section area larger than that on an upstream side of the ascending flow channel. A downstream end of the ascending flow channel and/or an upstream side of the descending flow channel is provided with a shrunk part which has a cross section area smaller than that on the upstream side of the ascending flow channel.
