Abstract

This disclosure is directed to a lavatory or kitchen water faucet with sink or basin whereat the disclosure attaches to the faucet preferably by a quick disconnect coupling means or other attachment means. The attachment means incorporates an aerator valve diverter fitting, the action of which is controlled by movement of a finger operated pull stem that protrudes from the side of said valve diverter fitting. When the stem is pulled, this operation causes the internal valve to divert the water flow which normally passes downwardly through the fitting and into the sink or basin, and instead directs the flow into an axially hollow sleeve or side outlet of the diverter fitting. The aerator valve diverter directs the water flow from the faucet through said side outlet sleeve and into an elongated flexible water flow line. The distal end of said flow line extends to a hand held wand with dual function control valve. The water continues through the valve and discharges into a pulsation mechanism within said hand held wand and finally exits into a water outlet tip, preferably demounted, and preferably able to direct said flow of water for dental cleaning. Moreover, the action of the dual function control valve associated with the wand allows the water flow rate to be adjusted between a maximum and a minimum rate and also allows the water flow to be switched off and on.
