A valve device includes: a hollow member having a through-hole with an axis, an internal surface delimiting the through-hole, a peripheral surface delimiting the hollow member's transverse extent with respect to the axis, and at least one deformation zone deformable to reduce the transverse extent when compression forces act on the peripheral surface, the deformation of the deformation zone moving the hollow member from a rest to a use state, and at least one closure portion extending radially from the hollow member inside the through-hole up to a respective free edge, in contact with the internal surface of the hollow member and/or with at least one free edge of another closure portion occluding the through-hole when in use. The at least one closure portion includes a flexible membrane, foldable when subjected to a fluid and/or solid pressure which moves in the through-hole along the axis, thereby defining a passage.

A central position of a water storage tank is provided with a drain opening; a water return bowl is in a short box shape, and is made of silicone; the bottom end of a skirt of the water return bowl is in direct contact with a bottom plane of the water storage tank to form a closed surface; a top plane of the water return bowl can attach to a grate, and the skirt of the water return bowl can be folded inwardly to form a curved flaky structure under drainage pressure; drain holes of the grate are provided on the edge of the water storage tank. Supports for supporting the grate are provided in the water storage tank. A gas buffer device is provided on the top surface of the flat-top water return bowl.

An insert, which can be installed as an odor stopper in the drain area of a household installation, e.g., in a drain pipe, includes a cylindrical area, which has a flange that projects outward. The insert also includes a closure area with an elastically deformable wall part. In the closure position, the wall part of the closure area rests against an opposite wall of the insert. In this case, the free edge of the wall part rests against the opposite wall from inside, creating an odor stopper. When water flows through the drain pipe, the wall part of the closure area is moved away from the opposite wall by the draining water, so that the closure area is opened. As soon as no more water flows through the insert, the wall part of the closure area again rests against the opposite wall, so that the odor stopper is created.

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 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.
