A modified toilet tank that serves as a fold-down urinal and fully functioning standard toilet in one to provide a more effective and mess-free way for males to use the toilet when urinating. The present urinal toilet device is more sanitary to use, eliminates messes on floors and toilet seats, is easier to use, and conserves water.

A constant flush toilet assembly to remove deposited waste is disclosed. The constant flush toilet assembly comprises one or more pressure sensors to actuate the flow of water in the toilet bowl via a plurality of nozzles when a user sits on the toilet assembly. The pressure sensors shut off the flow of water when the user gets up from the toilet assembly. A time delay pressure valve is provided to allow the flow of water to run from a T connector out to the toilet bowl. The nozzles are connected to the main supply line to spread water flow to maximize the cleaning force of the water against the toilet bowl. The present invention is also configured to be retrofitted in any existing toilet configuration as a toilet seat with plumbing and pressure sensors to clean the toilet bowl.

A water shutoff apparatus includes a housing and first and second valves located within the housing. The first and second valves are configured to be fluidly connected to an external appliance and an external first and second water supply lines that provide water at first and second temperatures to an appliance. The first and second valves include an open position, in which the water supply is enabled to supply the water to the appliance, and a closed position, in which the first water supply is prevented from supplying the water to the appliance. The first valve is independent from the second valve. At least one water sensor is electrically connected to the first and second valves. The sensor is operable between an inactivated state and an activated state when wet to activate the first and second valves to move into their closed positions.

Embodiments of the present invention relate generally to multi-port orbital valves for use in controlling the direction of fluids and mixed media, and find particular use in connection with toilet systems, such as vacuum toilet systems.

For combination with a flush toilet water tank having a side wall, a pond water receptacle integrated with said tank side wall at the exterior of the tank, the receptacle opening upwardly, there being a water passage through the tank side wall, whereby pond water in the receptacle has a gravity determined top level at approximately the same level as water in the tank, and a removable cover extending over water in the receptacle, protecting against contaminated pond water gaining access to tank water.

A toilet monitor uses a toilet tank water level sensor producing a toilet tank water level measurement signal. A processor detects rate of change of the measurement signal and conditionally produce a responsive actuation signal in response to the detected rate of change. A transducer connected to receive the actuation signal and transmit information, provide a humanly-perceptible indication, generate a data log and/or control an electronic water supply valve.

An in-toilet leak detector is disclosed, as are communication systems for reporting toilet leaks. The leak detector comprises an inlet that receives water from the toilet's fill tube and diverts it through a flow tube. A capacitive sensor is located between the inlet and an opening of the flow tube from which water flows into the overflow tube of the toilet tank. A housing is connected to the flow tube and the inlet and contains a controller and other electronics, including one or more transceivers. The leak detector measures the duration of water flow and establishes an alert if the water flow is shorter or longer in duration than a calibrated normal duration. The transceivers connect the leak detector to a computer network, and leak alerts are communicated to a server or servers so that they can be forwarded directly to those responsible for fixing the toilets.

Provided is a system, method, and apparatus for preventing repeated use of a restroom appliance with visual feedback. The system includes a valve configured to control flow of a fluid by at least one valve operation, an actuator configured to request a use of the restroom appliance, at least one indicator configured to display at least three different visual states, and at least one controller in communication with the actuator, the valve, and the at least one indicator. The at least one controller is programmed or configured to control the at least one indicator to display a first visual state, receive a plurality of requests to operate the restroom appliance exceeding a maximum number of valve operations, perform a first valve operation in response to receiving a first request, and control the at least one indicator to display a second visual state in response to performing the first valve operation.

The present invention is directed to a toilet that includes a slanted fill tube with an optical proximity sensor positioned on or within the inner surface of the fill tube. The optical proximity sensor includes an incoherent light source and a photodiode. The optical proximity sensor as disclosed herein detects small changes in volumes added to a toilet bowl. Consequently, small volumes of excrement that are deposited in the toilet bowl by a user may be detected with greater accuracy. In some embodiments, information about the volume of urine or feces deposited into the toilet bowl is recorded and calculated by a processor. Other sensors, including a toilet bowl water level sensor and a gas sensor may collect data in combination with the optical proximity sensor to provide more complete information about the user's health.
