Abstract
A plumbing fixture is provided with means for preventing flooding by obstructing the waste outlet thereof, such means being an overflow chamber along the edge of a bowl or basin, further provided with an electrical probe within the overflow chamber to complete an electrical circuit between the probe and the basin when the water level bridges the gap therebetween, thereby actuating a normally open solenoid valve to closed position for shutting off the supply of running water to the basin. The invention is applicable to a combination lavatory and water closet fixture for preventing flooding from either the bowl of the lavatory, or the bowl of the water closet, or both by providing such means for both bowls.

A plumbing fixture comprising:
- a bowl for liquid having a rim including structure defining an overflow chamber extending along the upper periphery of said bowl, said overflow chamber opening into said bowl and said structure providing an electrical ground, means including a supply line and a normally open solenoid valve in said supply line for supplying water to said bowl, a drain for said bowl, a sensing probe including a conductor extending through said overflow chamber in spaced relation to said structure providing said electrical ground, and means responsive to water completing an electrical circuit between said electrical ground and said sensing probe for energizing said solenoid valve and closing said supply line, whereby an overflow of water from said bowl into said overflow chamber such as may be caused by an obstruction in said drain will effect a termination of water supply to said bowl and thereby prevent water from overflowing the rim of said bowl.
