Abstract: A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

Abstract: A toilet overflow prevention system is provided and is incorporated with an otherwise standard toilet wherein the toilet bowl thereof is incorporated with an overflow inlet portal defined as a generally circular opening integrally formed within the left side of the concave inner wall of the toilet bowl. The overflow inlet portal provides passage to an auxiliary waste drain outlet which extends downward through toilet bowl frontal to the primary waste discharge pipe, and through the stool portion of the standard toilet, under which connection is made to an auxiliary waste outlet piping being in fluid communication with the primary waste discharge pipe. A reticulated grate element is mounted transversely atop the circular opening in order to trap debris contained within toilet bowl so as to facilitate ascension and discharge of water through auxiliary waste drain outlet, hence preventing unpleasant overflow.

Abstract: A toilet enhancement which utilizes four drain ports and a float to prevent a toilet from overflowing.

The ports are molded into the toilet bowl which would drain directly back to the main toilet line, therefore stopping water from flowing over the top of the toilet.

Abstract: An electronically controlled electro-mechanical device designed to limit a finite amount of water per flush to a tank reservoir of the common household toilet, or tank-less toilet or urinal, providing positive shutoff of water flow and anti-siphon backflow prevention. The toilet is flushed, the flush lever activates an attached tilt switch, the tilt switch actuates the countdown timer by means of electrical linkage, the countdown timer in turn activates the solenoid valve by means of electrical connection. The water enters the solenoid valve, passing through the valve and on to the float valve mounted to the toilet tank for fill up. The Countdown timer counts down from the full minutes and seconds set to 00:00 and shuts off the solenoid valve and ultimately the flow of water. The Countdown timer then resets itself to the time set in memory for the next flush operation. A float eliminator may be affixed to the toilet tank replacing the float valve, then connected to the solenoid valve.

Abstract: A toilet overflow control system is provided including a secondary float chamber and secondary float. The secondary float chamber is located below the toilet water tank and behind the toilet bowl at the water level of the toilet bowl and extending upward to the bottom of the toilet water tank. A vertical rod extends upward from the secondary float and is attached to a lever on the toilet water supply valve. This allows the secondary float to turn off the water when the toilet bowl water rises above a normal level. The vertical rod is inside a tube that allows it to go through the water tank without any loss of water. The secondary float chamber is fluidically connected to the toilet bowl by a horizontal conduit located just above the toilet bowl normal water level. A rinse hose is connected to the water supply valve to allow rinse water to flow into the secondary float chamber to prevent a back flow of water into the secondary float chamber during the flush.

Abstract: An improved flood level sensor has an upstanding, vented tube extending above and outside a receptacle while maintaining fluid communication with an enclosed rim of the receptacle. A partial vacuum is communicated to an orifice which is located within the tube at a height related to a limit on the level of fluid in the receptacle. The level of fluid in the tube depends upon the fluid pressure in the enclosed rim and therefore upon the fluid level in the receptacle. When the fluid level in the receptacle is below flood level, the orifice is able to relieve any partial vacuum communicated to it. However, when the level of fluid in the receptacle rises to the flood level, the fluid level in the tube rises to partially seal the orifice and prevent relief of the partial vacuum which then actuates a valve lockout device.

Abstract: A flood preventer has a pneumatically operable lockout mechanism to disable a valve actuator and prevent its repeated operation when fluid in a receptacle has reached an excess level. In the preferred embodiments the flood preventer has a latch that is responsive to a partial vacuum to engage a catch in the linkage between the valve actuator and a fill control valve. The partial vacuum is created by the flow of fluid into the receptacle through a venturi. The venturi is connected by a vacuum line to a fluid level sensing orifice that opens into the receptacle and relieves the partial vacuum when not blocked by fluid that has reached an excess level. In two other embodiments the partial vacuum is subject to the same conditions at the venturi and the orifice, but the lockout mechanisms are different. In the second embodiment a pin is dropped out to uncouple a valve actuator linkage, while in a third embodiment a jamming mechanism is used to block movement of the valve actuator.
