About This Product

The Chapin HydroFeed fertilizer injector is a patent-pending design filled with features for use with sprinklers and direct hose spray applications. Great way to conserve water and still have a lush, green, well-fed landscape or garden. Different than a Hose-end Sprayer: HydroFeed works differently than a standard hose-end sprayer. A standard hose-end sprayer pulls the chemical up and out, emptying the tank. HydroFeed adds water back into the tank as your chemical is being pulled out. Because your chemical has a higher density than water, it sits on the bottom of the tank. Our outlet tube reaches the bottom of the tank so when clean water is being added to the tank, it stays on top of your chemical mix. You don't have to worry about your chemical being diluted as it's being fed through the outlet tube. This is why the tank turns clear after your chemical runs out.

Highlights

  • 16-ounce clear tank
  • Funnel-shaped head for easy filling and monitoring usage
  • Ideal for liquid fertilizer
  • Adjustable connection elbow lets tank mount to any hose spigot
  • Large opening with O-ring for leak-free operation
  • Rigid inlet tube with filter for debris-free mixing
  • Drain plug with valve to quickly empty the tank after each use
  • Not compatible with drip irrigation systems
  • Return Policy

    Q:How many square feet of yard does this cover?
    by|Apr 24, 2023

    Answer This Question

    A:  Doesn't give yardage. It's dispersion depends on gallons per minute to apply the fertilizer so liquid is 1 oz per gallon and I use granules so it's 1/2 oz per gallon. So as long as you still have something in the tank in theory your entire run regardless of length is covered.

            This HYDROFEED 16 OZ. IN-LINE AUTO-MIX FERTILIZER INJECTOR SYSTEM FOR LAWN AND GARDEN APPLICATIONS arrived quickly, well packaged completely assembled. This product was selected for an off-label but similar application as a soap induction unit for a preliminary washdown area in my shop. It is installed down stream of a siphon braking fitting and upstream from the supply line to my pressure washer. I haven't calculated the actual mix ratio for the soap cycle, but find that I've got at least 12 minutes of high pressure soap mixture before it turns into to a rinse cycle for cleaning projects.

            Chapin HydroFeed 16 oz. In-Line Auto-Mix Fertilizer Injector System for Lawn and Garden. Easy to install and use, this auto-mix fertilizer injector can be used in your garden as well as when you water your lawn. It can use both granular as well as liquid fertilizers. Has a convenient built-in drain so its easy to winterize it with a simple flip of a knob. The clear tank makes it easy to monitor how much fertilizer you have left while you are using it. For me, its one of the easiest ways to fertilize my lawn and garden. Highly recommended.

            Big Time and Work Saver If you want to make fertilizer applications easy and quick this is the item to consider. What's in the box: 1 - Fertilizer Injector Head and Clear Canister With Drain Valve 1- 90 degree hose bib connector 1 - Instruction sheet First thing to consider before using this unit is the need for a back-flow preventer valve. This will protect your homes water supply and prevent the possibility of fertilizer and water mixture being pushed back into your domestic water system by loss of water pressure. The injector is easy to fill and easy to clean. The injector has a tall red cap on top; this is the fill port to add fertilizer. I find it much easier to remove the clear canister and fill that then screw the canister back on the fertilizer injection head. This is much easier to fill for me (your mileage may vary). This injector does not have an adjustable flow rate for fertilizer. You must dilute your fertilizer as directed by the fertilizer manufacturer. Once that’s done, the injector does all the work for you. This fertilizer injector saves a huge amount of work when feeding you lawn and other plants in your landscaping. No more walking behind a spreader or trying to feed by hand, now you can water like normal and let this injector do the work. This injector can use either liquid or dry granular fertilizers. Dry fertilizers should be dissolved in water before putting it into the injector. This fertilizer injector is a huge time and work saver. I would recommend that the clear injector canister be placed in the shade to reduce the chance of sun damage. The injector must also be removed if freezing temperatures are possible.

            The moment I heard about the "HydroFeed 16 oz. In-Line Auto-Mix Fertilizer Injector System for Lawn and Garden Applications", I decided to order one for myself. It is perfect for my front and back yards. No more carrying watering cans back and forth to fertilize my palms, bushes, and fruit trees with liquid and or granule fertilizers. Very easy to fill and clean. It can clearly be seen, when more fertilizer has to be added to the injector. I liked and I recommend it.

            This IN-LINE AUTO-MIX FERTILIZER INJECTOR SYSTEM is a nice design. It is a bit hard to hook up to a water spigot that is close to the ground like mine are. I had to hook it up onto my hose reel where the hose hooks up to. You can use either liquid or water soluble fertilizer in this unit. To fill with liquid you just unscrew the red plug and fill. To use granules, you unscrew the canister from the bottom and fill. Replace the canister and you are ready to fertilize. The granules worked great for me. I even had to clean out some unused granules when I was done.

            This 16 oz HydroFeed fertilizer injector will be used with the new raised strawberry bed along with a couple of dedicated tree watering systems. And possibly for the squash bed. It is shown being used at the strawberry bed. It would be nice if it had some mounting provisions. I will probably rig something up and put a manifold not too far from where it is shown and plumb it in so it can be used with any of the aforementioned irrigation systems. I will probably plumb it with quick connectors so it will be easy to move and not have to stay exposed to sunlight other than when it is being used. I have another 8 oz injector that is used with the garden drip system. It is not clear and so I cannot tell if the fertilizer is being dispensed. There have been times when it has not as I can see it when draining it out at the end of each use. I discovered that insects and spiders were entering the backflow preventer and clogging the orifices in the injector. Wrapping some Scotchbrite (tm) around the backflow preventer stopped this. All in all the Chapin 4700 seems to be a nice fertilizer injector and will be a welcome addition to our irrigation system as it gradually evolves.

            The Chapin Model #4700 HYDROFEED 16 OZ. IN-LINE AUTO-MIX FERTILIZER INJECTOR SYSTEM FOR LAWN AND GARDEN APPLICATIONS is a well-designed product for fertilizing gardens watered with drip irrigation, sprinkler, soaker hose or direct hose spray applications. We use soaker hoses to water our front and back gardens. The Hydrofeed is easy to change hoses from front to backyard soaker hoses. We can add fertilizer easily and know that our plants have received an effective feeding. It's a brilliant device and we are happy to put it to use.

            Very well made and it works great. The plastic is very thick and heavy duty, it is not cheap material. It comes with a small length of hose to connect to your spigot. The injector system works great and I've tried it for both soap and fertilizer with good results. Since I need to use it in both the front and back yards I have not mounted it to the house. It's easier to just move it from one location to the other rather than trying to bring the hose all the way around the house. My only complaint would be that its strictly designed to be mounted, otherwise it's a great product.
