Allows for water flow adjustment from the pressure pump. By adjusting the water flow through the ST-62, a restriction causes a vacuum which allows the detergent to be drawn through the hose barb when a large orifice nozzle is used.

With the adjustment feature, the ST-62 can be used with a variety of water flows, replacing injectors with fixed orifices that are sized to specific water flows.
