Abstract:
For use with a dental unit including a plurality of devices through which water can be passed from a pressurized water source through a primary water line into which one of pressurized air and disinfectant solution from respective sources thereof can be selectively introduced through a double inlet single outlet first router valve, a selectively operable removable purge unit for flushing and disinfecting said primary water line and devices comprising:a) a solution reservoir for containing a disinfectant solution and ullage,b) a double inlet single outlet second router valve,c) an inlet air line removably connectable between the pressurized air source and alternately one of the reservoir ullage and a first inlet of the second router valve,d) a solution line between the solution reservoir and a second inlet of the second router valve, ande) a connection line for one of air and solution from the single outlet of the second router valve removably connectable to the primary water line,f) whereby water can be expelled from said primary water line and devices by pressurized air and replaced with disinfectant solution displaced by pressurized air from the ullage of the reservoir which solution can then be expelled by pressurized air and replaced with water.
