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.
Claims3
A sink drain system, comprising:
- a quarter turn valve disposed within a drain;
- a first directional vane enclosed within a first housing adjacent the drain, the first directional vane attached to the quarter turn valve to cause rotation for opening the quarter turn valve when water flows through the first housing;
- and
- a second directional vane enclosed within a second housing adjacent the drain, the second directional vane attached to the quarter turn valve to cause counter-rotation for closing the quarter turn valve when water flows through the second housing.
