A drain installation assembly includes a drain body and a drain coupling. The drain coupling is configured to be inserted into a drain opening of a wash basin from a top side of the wash basin. The drain coupling comprises a first coupling end and a second coupling end, the second coupling end positioned opposite to the first coupling end. The drain coupling further includes a squeeze portion positioned between the first coupling end and the second coupling end, the squeeze portion formed of a flexible material. The drain body comprises a body flange extending radially away from the drain body. The squeeze portion is configured to deform, so as to define a squeeze bulge when the drain coupling is coupled to the drain body, the squeeze bulge having a diameter greater than a diameter of the drain opening of the wash basin.

A stopper assembly for a drain system of a fluid basin. The stopper head assembly includes a stopper head having a seal to sealingly engage the drain system of the fluid basin when the stopper assembly is moved from a drain position to a plug position and a strainer to strain fluid passing through the drain system when the stopper head is in a drain position. The stopper head assembly further includes a stopper body operably coupleable to a control element to move the assembly between the drain position and the plug position. The stopper body may be detachably coupled to the stopper head and/or the strainer to enable selective removal of the stopper head and the strainer from the stopper body when the stopper body is installed for use and coupled to the control element. Related methods, systems and components are also provided.

A drain screen for capturing debris in a fluid in a drain. Said drain screen comprising a faceplate, a center axis, and a one or more beams. Said faceplate comprising a one or more aperture-catch arrangements, said center axis, an edge, a top surface, and a bottom surface. Said drain screen comprises a radially outward direction and a radially inward direction. Said drain screen configured to allow a fluid to move over said faceplate from said radially outward direction toward said radially inward direction. Said radially inward direction is defined as a direction across said faceplate toward said center axis. Said one or more aperture-catch arrangements comprise a one or more apertures and a plurality of raised portions. Said plurality of raised portions are arranged said radially outward direction of said one or more apertures.

A drain cover including a positioning member arranged to surround an opening of a pipe of a drain and fit within the pipe, the positioning member including a plurality of openings, and a resilient sealing member connected to the positioning member at a center point, the resilient sealing member including a rim arranged concentrically about the center point. The rim contacts the positioning member to prevent fluid from passing through the plurality of openings in a closed position. The rim does not contact the positioning member to allow fluid to pass through the plurality of openings in an open position.

A lockable plug device for sanitary ware comprises a closure member operable to engage with an outlet or drain of the sanitary ware product to stop water emptying from the sanitary ware product, for example a bath. The lockable plug device also includes a closure mechanism, which is linked to the closure member and is operable to displace the closure member relative to the outlet or drain such that the outlet can be open or closed. The closure mechanism comprises a lock feature, which is operable to lock the closure member in an open position.
