1. Waterite W-988 Air Injector

The Waterite W-988 Air Injector
systems. This plastic air injector features plumbing connections of the 1" Male Threads and a flow range for
effective air draw of 3.8-16 gallons per minute.
The air injector has an inlet and outlet (see arrow on side of air injector for
proper installation). When the well pump turns on, water enters the air
injector and is split between the nozzle portion of the injector and the bypass
portion. The amount of water entering the nozzle area is regulated by the
bypass screw. The further the screw is tightened (clockwise) into the air
injector the greater the flow of water onto the nozzle.
As water is restricted into the nozzle and enters the venture a vacuum is formed at this point. This vacuum
creates the air draw into the water. As mentioned the further the bypass screw is tightened into the air
injector the greater the air draw during the pump cycle. Also as the air draw increases the water flow rate
through the air injector and to the home decreases.
