A flow protector which protects drain weep holes. The flow protector is a cover, which maintains a space on top of the drain assembly that includes the weep holes which receive under-floor moisture, the flow protector cover including a top surface forming an angled surface, surrounded by an outer perimeter edge which is spaced from the top surface of the clamping ring, and forms an opening to the space only around the outer perimieter edge, This protects against mortar and other materials spilling into the weep holes.

A through-floor combination tub and surface drain includes an exterior tube having a top end and a bottom end. The bottom end of the exterior tube is to connect to a sewer pipe. The top end of the exterior tube has one or more openings to provide a floor drain. The drain also includes an interior tube situated within the exterior tube. The interior tube has a top end to receive a drain pipe and a bottom end that opens into a cavity within the exterior tube that extends from the top end of the exterior tube to the bottom end of the exterior tube. The drain further includes a flange, extending outward radially from the exterior tube, to connect to a substrate of a floor.

A drainage assembly and a sink are provided. The drainage assembly includes a base body. Two ends of the base body are provided with an input port and an output port respectively. The input port is communicated with the output port by a flow channel located in the base body. The flow channel includes an upper chamber communicated with the input port and a lower chamber communicated with the output port. The base body is provided with a switch mechanism configured to control connection and disconnection between the upper chamber and the lower chamber. The base body is provided with a water inlet connector and a liquid level measurement connector that are separately communicated with the upper chamber. The drainage assembly and the sink have liquid level measurement and water supply functions in addition to a drainage function.

A wash stand comprising a wash basin having a drain opening which opens into a drain chamber. In the drain opening there is a cover which extends over part of the drain opening such that, at least in a lower region of the drain opening, a gap is created through which water can flow out of the wash basin into the drain chamber. In the drain chamber there is at least one mounting point on which the cover is supported removably by the at least one mounting point. The cover in the at least one mounting point is mounted pivotably about at least one pivot axis such that the cover can be pivoted from a use position into an intermediate position in which the cover can easily be grasped by a user. From its intermediate position, the cover can be removed from the mounting point out of the drain opening.

A tile drain and method of installing a tile drain is provided. The tile drain includes a drain body and a drain cover. The drain body defines a top opening, top weep apertures, and bottom weep apertures. The top opening receives the drain cover and serves as the primary drain for the tile drain. The top weep apertures are positioned below a top layer, such as a tile layer, of the base so as to receive fluid positioned between the top layer and a top waterproofing layer of the base. The sub weep apertures are positioned below the top waterproofing layer of the base so as to receive fluid positioned between the top waterproofing layer and a bottom waterproofing layer of the base. The drain body is encapsulated within the base, but the drain cover is adjustable relative to, and removable from, the drain body.
