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.
