Step 2. Gently tug the tubing to insure it is locked into place.
Side View
To Remove:
Step 1. Shut off pressure to the system.
Step 2. Apply gentle pressure to the Green or Blue Collet with your fingers.
Step 3. While holding pressure, gently pull the tubing away from the fitting to release.
Note: Make sure to direct the fitting away from your face and body. A small amount of residual pressure may be in the tank and cause a momentary release of fluid.
System Installation
Typical installation
The EZ-FLO Mainline Injection systems are normally installed in a valve box,
connected to the main line of the irrigation system after the back flow
preventer. This will allow the system to inject to any irrigation zone valve
located after the installation point. One unit will feed both drip and
sprinkler zones automatically adjusting for pressure and flow.
**TOP VIEW MULTIPLE ZONE INSTALLATION
**
FEEDS ALL IRRIGATIONS ZONES
HIGH PRESSURE MAINLINE SYSTEM REQUIRED
INSTALL ANYWHERE BETWEEN BACK FLO PREVENTER AND FIRST ZONE VALVE
Step 1 – Locate the installation point and pipe size
- Connection must be made after an approved back flow prevention device.*
- The connection can be made either vertically or horizontally in the irrigation main line.
- The connection may be installed above or below the tank without issue.
- The connection may be any distance from the back flow prevention device.
Use only the correct size connection for the installation as indicated on the CBV box label.
Part# | Mainline Size |
---|---|
CBV-100 | 3/4” & 1” |
CBV-125 | 1.25” |
CBV-150 | 1.5” |
CBV-200 | 2” |
CBV-250 | 2.5” |
CBV-300 | 3” |
CBV-400 | 4” |
Do not use reducing bushings on the CBV unless directed to by an EZ-FLO
representative (does not apply to CBV-100).
If your irrigation mainline has multiple diameters, such as a pump discharge
to a larger mainline,it is best to install in the smallest diameter available
to obtain best performance.
*Installations on a mainline may only be used with a mainline rated system. Installations after a zone valve or on a well may not be subject to the same back flow requirements.
Main Line Connection
Step 2 – Shut off water and relieve pressure
You can use the valve on the back flow prevention device (pictured) or shut
off your water main.
Step 3 – Cut out a section of pipe slightly larger than the cut out
length of the coupling.
Step 4 – Glue the coupling into the line.
CBV-100 ONLY
USE INCLUDED REDUCING BUSHINGS FOR 3/4” PVC INSTALLATION
Step 5 – Attach tubing to the coupling.
ATTACH BLACK TUBING TO BLUE FITTING, CLEAR TUBING TO GREEN FITTING AND
SECURE WITH TUBING CLAMPS
Fill Tank with Product
Step 6 – The EZ-FLO system can be filled with any liquid or water soluble
product. EZFLO MAXX PRODUCTS are specifically designed for use with
fertigation and all irrigation systems.
Fill the tank based on the product’s coverage recommendations
Typical Fertilizer Coverage Rates:
Liquid- 1 Gallon per 10,000 sqft every 4 to 8 weeks
Powder- 1 Pound per 1,000 sqft every 4 to 8 weeks
Pour fertilizer directly into tank and then top off with water until all air
is gone from the tank. If your fertilizer is not colored, add blue or green
dye
Model | Tank Size | Maximum Capacity |
---|---|---|
EZ001-CX | 1.5 Gallon | 10 lbs dry or 1.5 gal. liquid |
EZ003-CX | 2.5 Gallon | 15 lbs dry or 2.5 gal liquid |
EZ005-FX | 4.5 Gallon | 25 lbs dry or 4.5 gal liquid |
EZ010-FX | 8.5 Gallon | 50 lbs dry or 8.5 gal liquid |
ALL TANK CAPACITIES ARE APPROXIMATE
Fill tank with product
Follow all product label precautions. Multiple products can be combined and
applied all at one time. Base how much to put in the tank by each product’s
coverage recommendations.
DO NOT LEAVE AIR IN THE TANK
Air will fracture the tank and is not covered by the warranty
Fill tank with water from shut off valve or hose until full
Step 7 – Screw on tank cap
Check to make sure o-ring is in place under the cap prior to screwing the cap back on.
Connect Cap to Irrigation System
Step 8
Shut off valves in the off position.
Turn water on at back flow preventer
Connect blue connector to water in connection by pressing the black tubing
into the blue fitting.
Water In – Blue Connection
Connect green connector to fertilizer out connection by pressing the clear
tubing into the green fitting
Fertilizer Out – Green Connection
Open both shut off valves
Connector Calibration – 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 composed of spray heads or larger drip irrigation zones, adjustment to the CBV may not be required.
The EZ-FLO system must be full of fertilizer which provides a color that can be used to indicate flow through the clear line. If your fertilizer 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.
PROPORTIONING CAP
CBV Full Open
CBV Full Closed
Step 9 – Turn on a sprinkler or drip zone with the closest to average
gallons per minute flow rate and watch the clear, fertilizer-out tubing for
color.
If color is steadily flowing through the clear output tube, the CBV does not require adjustment. Please note the color in the tube will be lighter than the color in the tank due to the mixing.
If color is not flowing through the clear tubing, slowly turn the CBV to the closed position in small increments, stopping once color begins to flow.
Once color is visible, you no longer have to adjust the CBV connection. You may leave it in position permanently.
To prove the system is working, adjust the feed setting on the cap, back and forth. While the irrigation system is running, turn the knob from slow to fast, and fast to slow. Each time you adjust the knob to a new setting, the color in the tube will change. Slower settings are lighter and faster setting are darker.
Once all is confirmed, set the proportioning cap feed rate to the desired setting per your systems instructions.
For additional information, please read the FAQ/ Troubleshooting in the CBV instruction manual.
Set Flow Adjustment
Step 10 – Set the flow rate by turning the adjustment knob to the proper setting.
Slow Setting – is used for normal and most common setting in regions with high watering requirements such as hot dry climates or sandy soils.
#1 Setting – is used for normal maintenance in regions with more moderate climates and moderate watering schedules where soils have good moisture retention.
#2 Setting – is used to encourage fast growth or to quickly improve the condition of a landscape in poor condition. The unit will empty more quickly and can be refilled more often.
Fast Setting – is used to for periodic fertilization. The unit will empty more quickly and can be refilled more often.
Setting| *Ratio| OZ. of fertilizer per gal. of water| Based
on Watering Frequency
---|---|---|---
Slow| 15000:1| 008 (1/20 tsp)| 4+ days per week
1| 8000:1| 017 (1/10 tsp)| 3 days per week
2| 2000:1| .064 (2/5 tsp)| 2 days per week
Fast| 400:1| 320 (2 tsp)| 1 day per week
PROPORTIONING CAP
*Ratio refers to the amount of water mixed with the fertilizer. For
example, a 400:1 ratio means 400 gallons of water will be mixed with 1 gallon
of fertilizer. The adjustment knob can be set in between settings if desired.
These ratios are approximate because feed rates can vary by the type of
product being distributed. Ratios are provide as a general guideline only.
The watering frequency guideline is general and for convenience only.
Additional caution and care should be taken when using a feed setting faster
than #1
Gallons of Water Until Empty
The following table shows the approximate gallons of water required to distribute the fertilizer from the EZ-FLO system at the various flow settings.
Mode | EZ001-CX | EZ003-CX | EZ005-FX | EZ010-FX |
---|---|---|---|---|
Slow | 22,500 | 37,500 | 67,500 | 127,500 |
# 1 | 12,000 | 20,000 | 36,000 | 68,000 |
# 2 | 3,000 | 5,000 | 9,000 | 17,500 |
600 | 1,000 | 1,800 | 3,400 |

FAQ
How much product to put into the tank
Refer to the product label and tank capacity from page 6. Additional information is on our website.
What fertilizer can I use
Almost any liquid or water soluble powder product. Do not use dry broadcast fertilizers.
Can I use weed killer/ herbicide in the system:
Typically no, hazardous products are not recommended for use in the EZ-FLO system.
What cap setting should I use
Slow and #1 are the most common cap settings. Page 9 offers more details on each setting.
How often do I need to refill:
This will vary on landscape size and watering schedule but typically every 4 to 8 weeks.
How do I know when to refill
The system can be checked for color by in the clear output tubing during irrigation operation. If the fertilizer color is gone, you need to refill the system. Alternatively, you may let the system run without fertilizer (just water) and refill based on a set schedule
How do I know it is working:
When the irrigation system watch the clear output tube for color. You may adjust the cap from slow to fast to see the color change. You can use blue or green food dye to add color to the fertilizer.
Will I over fertilize
No, the EZ-FLO injection process micro doses products but we do recommend caution when using new products and faster feed settings.
Will the system clog drip irrigation:
No. EZ-FLO and Maxx-Products can help clean drip systems and make them work effectively.
If product is mixed with water, will it dilute:
No, the patented process and agitation valve control dilution of compatible products.
Will the fertilizer stain
Not if using EZ-FLO recommended products. Check other manufacturers labels if not using EZ-FLO brands.
How do I winterize the system:
Simply close the shut off valves, disconnect it from the irrigation system and drain the tank.
The system did not inject any fertilizer
Refer to the “Connector Calibration“ and set the CBV to a further closed position.
The system is emptying too fast
Confirm you used the correct cap setting and check the “Connector Calibration” page and adjust the CBV to a more open position.
My system is always full of water, is it working
Yes! This is part of our patent and you can review the videos on our website to see how it works.

Troubleshooting:
I cannot see color when closing the ball valve:
Confirm you have set the knob to fast. Check to see that both shut off valves
on the tubing are open. Confirm you have a zone of irrigation running (water
flowing). Confirm you have added enough fertilizer and that it has a color

Agitation Valve Operation
(Optional)
When using fully concentrated water soluble powders, it is recommended to have
the Agitation Valve ON.
In the ON position, the agitation continues to stir and dissolve
concentrated product at the bottom.
Significant dilution of the solution does not occur until the powder has fully
dissolved.
If only liquid is used, a slow steady dilution can occur at faster feed rates.
The ON position is illustrated by the image in **figure 1.
When using fully concentrated liquid, diluted liquid, or dissolved powder
products, it is recommended to have the Agitation Valve OFF.
In the OFF* position, the agitation no longer mixes at the bottom.
Significant dilution of the solution does not occur
The OFF position is illustrated by the image in **figure 2.
* EZ-FLO tested the Agitation Valve with standard mineral fertilizers, micro
nutrients, and acids. Observed variations are +/- 5%. Some products, primarily
organic supplements, and humic acids, will leave residue and cloud the
solution even when dispensed accurately.
How it works
Quick Refill Guide
Step 1 – Turf off the water using the shut off valves, both valves
must be closed
Step 2 – Disconnect tubing from both sides
Step 3 – Unscrew cap & pour out water
The system will be full of fresh water when fertilizer is gone
Some products may leave a slight residual. This may be left in the tank or
flushed out.
Step 4 – Fill tank with product
