Three flat spray openings are positioned to produce a self-rotating force and to provide full spray coverage. Water Options A water wagon and an outside household hydrant are the two most popular methods of supplying water for the pressure-rinse nozzles. The preferred water source is the transfer pump found on most water wagons. This device separates the filling and rinsing of sprayer tanks from sources of drinking water. A pressurized water line can be tapped by removing the plug from the priming port on the transfer pump.
Water pressure is supplied any time the pump is operating.
A second valve may be installed before the male hose connector at the priming port to facilitate pump operation in the event the garden hose is removed. This option provides easy access to a source of water pressure for washing hands, washing equipment, or cleaning up spills. Turn the tank fill-line valve off for maximum pressure when rinsing containers. Operate the rinse nozzles at a minimum of 30 seconds at 10 to 20 psi to achieve effective rinsing. Some materials and containers may need rinsing as long as 1 to 2 minutes.
