Abstract
A drain system includes a basin and a drain, where a first one of the basin and the drain comprises at least two substantially inflexible protrusions and a second one of the basin and the drain forms at least two apertures. The protrusions and apertures form male-female connections that facilitate positioning and anchoring of the drain in the basin. Further, stoppers/strainer and ball valves for limiting or ceasing water flow through a drain are disclosed. The stoppers/strainers and quarter turn valves may be switch-activated and moved into position by electricity, water pressure, air pressure and the like.
