Abstract: A dental prophylaxis and water conservation device for in-home use. The device includes a tank coupled to the household water supply line and adapted to receive water which causes air contained within the tank to be pressurized. The water and air from within the tank are connected by lines to a handpiece which discharges both mediums simultaneously. Water leaving the tank passes through a container having an abrasive material which is picked up by the water and also discharged. The tank is further coupled to a plumbing fixture, such as a shower head. This enables the tank to be used as a water conservation device by allowing cold water to be purged from a hot water line into the tank, and subsequently used to provide water to the plumbing fixture. To recycle the purged water, the present invention entrains the water from within the tank as water from the supply line is being provided to the plumbing fixture.

The lower housing includes an upper housing reservoir in communication with a sink within the central housing for storage and subsequent disposal of fluid within the lower housing.

Abstract: A control system for water faucets comprises an on-off control switch located at a sink and actuated by pressure applied and released by the body of the user. When the body of the user pushes forward towards the sink, the switch will be depressed and the water faucets will turn on. When the user backs away from the sink, the switch will be released and close off the flow of water. An overflow reservoir is provided to collect cold water run off prior to the time when hot water makes its way through the water pipes, and a temperature sensor switch and/or alarm controls either an automatic or manual change over from hot to cold water. In addition, a microprocessor and key board control various water delivery functions such as volume and temperature. The control system reduces leakage and saves water which would otherwise be lost due to running the hot water until it becomes heated to the desired temperature.

Abstract: A diverter apparatus and method of saving fresh water from being wasted while one waits for the cold or lukewarm water that accumulates in a hot-water pipeline to pass therethrough before the usable hot water begins discharging from a shower fixture or from a faucet fixture. The apparatus comprises a two-way diverter valve having an inlet port and two outlet ports. The inlet port is attached to the shower or faucet discharge fixture whereby the fresh water can be diverted to one of the outlet ports which is connected to one end of a hose. The hose is interconnected between the diverter valve and a storage container so that the initial cold water passes through the hose for storage in the container until hot water is discharged whereby the cold water is prevented from being wasted down a drain. The other outlet port of the diverter valve is adapted to receive a shower-head fixture or a faucet-aerator fixture.

Abstract: A self-contained sanitary fixture, particularly for a recreational vehicle, comprises a bench supported on a base cooperatively defining a stowage compartment. The bench contains a bowl having an outlet which connects to a tank in the storage compartment. A valve on the tank controls passage between the bowl and the tank. The valve is itself operated from a knob on the bench through a coupling mechanism. Waste water from the bowl is collected in the tank and is disposed of by sliding the tank out of the stowage compartment through an opening in the RV's sidewall and carrying the tank to a suitable disposal site. The tank incorporates a rotatable pourspout and vent valve to facilitate pouring waste contents out of the tank. The connections between the bowl outlet and the tank and between the knob and valve automatically disconnect upon removal of the tank from the stowage compartment. Similarly they automatically reconnect when the tank is inserted back into the stowage compartment.

Abstract: A portable hand wash unit is comprised of a tank having a dispenser housing hinged to the upper portion of the tank. The dispenser housing is shaped to define a pair of wash basins, each having a water outlet connected in continuous communication with a metering receptacle and each basin having a soap dispenser pump connected in communicating relation with a soap reservoir. Each wash basin is provided with a manual water pump which pumps clear water from a bag of water within the tank through the inlet of each metering receptacle. The inlet for each metering receptacle has a cross-sectional size approximately twice the cross-sectional size of the water outlet, thereby allowing a user the time needed to wash his hands after the user has finished operation of the water pump.
