No electricity, no batteries, no moving parts.

Professional Results Without the Effort
Connect once, then let your irrigation handle the feeding. Every watering cycle delivers a precise, measured dose of nutrients.
Watch How EZ-FLO Works
Save Up to 50% Water
Fertigation delivers nutrients directly to the root zone, so you water less and waste nothing. Every drop counts and every drop works.
Save 10+ Hours a Month
No more mixing, measuring, or spreading fertilizer by hand. Your system feeds automatically every time you water.
Get 2-3x Better Growth
Consistent micro-dosing outperforms periodic granular application every time. Healthier plants, deeper roots, stronger growth.
Differential Pressure Technology
Unlike Venturi systems that lose 20%+ pressure, EZ-FLO operates in a closed loop with negligible pressure loss. Your sprinklers perform exactly as designed.
Quick-Fill Port System
Refill in minutes, not half an hour. The top-mounted fill port and bottom drain valve mean no disconnecting hoses or digging up the tank.
Auto-Adjusting Flow
Works with high-pressure rotor zones and low-pressure drip lines equally well. No recalibration needed between zones.
Zero Moving Parts
No pistons. No seals. No motors. Solid-state fluid dynamics means nothing to wear out, nothing to service, and completely silent operation.
Adjustable Feed Ratios
Dial from 15,000:1 slow micro-dosing to 400:1 rapid correction with the cap-mounted control. Adapt to seasons and plant needs without tools.
Visual Flow Confirmation
The clear output tube acts as a sight glass. See the colored fertilizer solution flowing through the system. When the color runs clear, it's time to refill.
EZ-FLO waters almost anything. Works with full irrigation systems or a simple faucet and hose.
Automatic Fertigation, Every Zone
EZ-FLO connects inline with your existing irrigation system. Water flows through the tank, picks up a precise amount of fertilizer, and delivers it evenly to every zone, automatically adjusting to pressure and flow changes.
Water Enters the System
Pressurized water from your main line flows into the EZ-FLO tank through the patented injection assembly.
Fertilizer Gets Injected
As water passes through, it picks up a proportional amount of concentrated fertilizer from the tank. No pumps or electricity required.
Solution Distributes Evenly
The nutrient-rich water flows through your irrigation system, reaching every zone with the same consistent concentration.
Plants Get Fed Every Watering
Instead of monthly fertilizer spikes, your plants receive gentle, continuous nutrition every time the irrigation runs.
Install in 15 Minutes. No Plumber Needed.
No special tools. No technical skills. Just connect, fill, and let your irrigation handle the feeding.
Connect to Your Water Line
Attach to your hose bib, spigot, or irrigation mainline. Color-coded fittings make it straightforward.
Add Your Fertilizer
Pour in any water-soluble fertilizer. One fill lasts 4-6 weeks depending on your watering schedule.
Turn On and Grow
That's it. Every time you water, your plants get the right dose of nutrients automatically.

What Our Customers Say
Real reviews from verified EZ-FLO customers.
So easy to use, such a timesaver
With EZ-FLO doing the fertilizing, it's freed up my weekends completely. My garden has never looked better and I barely have to think about it.
I bought eleven of them
I love these so much, I bought eleven of them. My soil is pretty bad, and I needed something that would help me fertilize daily. I put one for each garden bed plus some newly planted trees, added fish fertilizer, and everything just exploded with growth.
No lugging watering cans around anymore
I like it for its quality build, simple operation, and the fact you can leave it alone at the tap and walk the hose. No more lugging watering cans around the garden. My back thanks me.
Worked perfectly from day one
This unit worked the first time with no issues and provided the expected amount of fertilizer within the timeframe I calculated. Setup was straightforward. Would not hesitate to buy another.
The EZ-FLO is awesome
Wow, the EZ-FLO is awesome. The staff were incredibly helpful and the product does exactly what it says. I would take my EZ-FLO with me wherever I went if I could.
Nothing short of spectacular results
With zero work on my part, the plants are much greener. I use the 1-gallon unit for backyard plants and a smaller one for the vegetable garden. My Tuberous Begonia flowers are 6 inches across now.
The EZ-FLO Guarantee
Try it for 60 days. If you're not seeing healthier growth, we'll refund every cent. No questions asked. Plus, every system comes with a 5-year warranty on parts and craftsmanship.

See the Difference EZ-FLO Makes
Real photos from real customers. No tricks, no filters. Just consistent fertigation doing what it does best.
See What EZ-FLO Does in One Year
These photos show an actual new home landscape at planting and that same property one year later. No additional plants were added. One EZ-FLO unit with a single fertilizer blend fed the entire property automatically through the existing irrigation system.
From New Planting to Full Coverage
Most homeowners wait years for a new landscape to mature and fill in. With EZ-FLO, small starter plants grow into dense, lush foliage in a fraction of the time. Just 10 minutes every 4-6 weeks to refill the unit. The rest happens automatically through your standard in-ground irrigation.
Frequently Asked Questions
Everything you need to know before choosing your fertigation system.
Will it clog my drip emitters?
No. Water-soluble fertilizers are slightly acidic, which actually helps prevent mineral buildup in drip lines. Many users report their drip systems run cleaner after installing EZ-FLO. Just use quality water-soluble products and you’re set.
Does it need electricity?
No. The system runs entirely on water pressure using patented differential flow technology. No batteries, no plugs, no solar panels. Connect it to your irrigation line or tap and it works automatically every time you water.
How do I know when it's empty?
The clear output tube acts as a sight glass. When the system is running, you’ll see colored fertilizer solution flowing through the tube. When it runs clear, the tank is empty and ready for a quick 5-minute refill. Most users refill every 4-6 weeks.
Is it safe for pets and children?
Safer than traditional methods. Because EZ-FLO micro-doses, the water exiting your sprinklers contains a very dilute nutrient solution, far less concentrated than granular fertilizer sitting on the lawn surface. Kids and pets can use the lawn right after watering. Always check your specific fertilizer labels for additional guidance.
What fertilizers can I use?
Any fertilizer that dissolves in water. We offer our own MAXX-PRODUCTS line formulated specifically for fertigation, including fertilizers, repellents, and soil supplements. You can also use products from Jack’s, Peters, Miracle-Gro, or professional-grade options. Organic options like fish emulsion and seaweed extract work well too. Avoid products with large particles that won’t fully dissolve.
Can I install it myself?
Yes. If you can handle basic PVC work or connect a garden hose, you can install EZ-FLO yourself. Most homeowners complete installation in 30-60 minutes. Any irrigation contractor can do it even faster, or you can connect directly to an outdoor tap for zero plumbing.
What about winterization?
If you’re in a freezing climate, drain the tank before winter using the bottom drain valve. Takes about 30 seconds. The tank material can crack if water freezes inside, so treat it the same as your irrigation system. Most users winterize everything at once.
What does the warranty cover?
Every system comes with a 5-year warranty on the tank and all components, backed by Reliance Worldwide Corporation (the company behind SharkBite plumbing). There’s also a 60-day satisfaction guarantee: if you’re not seeing results, return it for a full refund. No questions asked.
Will it work with my water pressure?
Almost certainly. EZ-FLO works with any standard residential or commercial water pressure from 15-80 PSI, which covers virtually every home and irrigation system. It handles everything from low-flow drip lines (as low as 0.5 GPM) to high-volume rotor zones. The system auto-adjusts to your flow rate, so no calibration is needed.
Do you offer trade pricing for professionals?
Yes. We have dedicated trade programs for landscapers, irrigation contractors, and resellers with volume discounts and wholesale pricing. Apply for a trade account or call us at (866) 393-5601 to discuss your needs. We also offer site assessments and custom solutions for commercial projects.
