Size the Model to your Landscape
What size model you choose to order is dependent on a few factors.
• What is the composition of the landscape materials? Turf uses more irrigation water than a dense ground cover or shrubs with deeper root masses.
• What products are you interested in applying through your irrigation system? Some products have higher application rates than others.
• How often do you want to refill?
In the end; this last point is the one that is the ultimate determining factor. If you want to refill less frequently; simply go up in size. If you do not mind refilling more often; then you can get by with a smaller size than what would be recommended. The following table identifies a typical landscape configuration and sizes that can be served with each EZ-FLO main line model along with other sizing information.
Please note that coverage levels assume a 4-6 week desired refill cycle for EZ001CX to EZ010-FX models. High capacity models (designated as HC) are designed for commercial landscapes serviced by professional maintenance companies. Property sizing for those units is based on a 2-3 week refill schedule. Growers and nurseries use other sizing metrics (pounds per square foot and PPM) which can be found in their related web pages.

Fertilizer Distribution Rates
EZ-FLO's patented flow technologies ensure that the proportion of fertilizer to water remains constant from the beginning of the cycle until the tank is depleted of fertilizer.
For a detailed look at how EZ-FLO's technology works see our Technical Specifications.
All EZ-FLO fertigation units have an adjustable cap with four reference settings corresponding to the amount of fertilizer mixed with the water: The cap can also be set at points between these four reference settings for unlimited adjustment flexibility within the maximum and minimum proportioning rates for the cap.
Main-line Cap
| Cap Reference Setting |
Water to Fertilizer Proportioning ratio |
| Slow |
15;000 to 1 |
| 1 |
8;000 to 1 |
| 2 |
2;000 to 1 |
| Fast |
400 to 1 |
The following table shows actual fertilizer proportioning rates converted to ounces; teaspoons and milliliters at the various cap reference settings along with the approximate gallons of water through the irrigation system that will empty a given size tank:
