Adjusting the ball valve will not affect the performance of the irrigation system.
Connect Callibration - Coupling Ball Valve
The CBV connection must be calibrated to the flow rate of your irrigation system. If the irrigation system
is higher flow, primarily compsed of spray heads or larger drip irrigation zones, adjustment to the CBV
may not be required.
The EZ-FLO system must be full of fertiliser which provides a color that can be used to indicate flow
through the clear line. If your fertiliser is not colored, add blue or green dye to the tank.
Start by setting the proportioning cap adjustment setting
to the fast position and the CBV in full open position.

Turn on a sprinkler or drip zone with the closest to average liters per minute flow rate and watch
the clear fertiliser out tubing for color.
If color is steadily flowing through the clear output tube, the CBV does not require adjustment.
Once color is visible you no longer have to adjust the CBV connection. You may leave it in position
permanently.
Full closed is not common and may indicate improper installation or filling of the system.
Set the Proportioning Cap feed rate to the desired level.
The valve closure is only necessary when the irrigation system is not operating at full capacity.
Water is diverted through the EZ-FLO system as a bypass and reintroduced downstream of the
valve eliminating the pressure and flow loss.
The color in the tube
will be lighter than
the color in the tank
due to the mixing.
Note:
The color will be
lighter on the slower
feed rate settings.
