Featuring a clear tank for easy monitoring, a leak-proof O-ring seal, a built-in mounting bracket, and a debris-filtered inlet tube, it ensures precise, mess-free fertilizer application. Ideal for liquid, granular, or fish emulsion concentrates, this unit simplifies garden feeding while conserving water and maximizing plant health. ## Description The Chapin HydroFeed fertilizer injector is a patent-pending design filled with features for use with sprinklers and direct hose spray applications. Mixes water with liquid, granular and fish emulsion products at the water source. This irrigation system comes with a clear tank for easy monitoring of usage, a large opening with O-ring to prevent leakage, funnel-top mouth for easy filling, built-in mounting bracket for easy set up next to water spigot, rigid inlet tube with in-tank filter for debris-free mixing and drain with valve to quickly empty remaining product and water from the tank. Great way to conserve water and still have a lush, green, well-fed landscape or garden. Review: My setup: I use these with a drip irrigation system in my garden, and smart valves installed after these units to turn on/off the flow. I have a backflow preventer installed upstream of each unit to make sure I don't get fertilizer contaminating the main water source. I use jacks 20-20-20 fertilizer dissolved in water, I have not tried putting solid fertilizer pellets in, which the instructions say should work. Comes with a short hose (about 1ft (30cm)) which is handy for connecting to a downstream valve or splitter. Basic thoughts: These units cause no issues with the drip system or the smart valves and are easy to fill up. I let the regular water flow through these all the time and just add fertilizer whenever I want to feed the garden. If you only use with fertilizer, downstream valves or irrigation systems might be affected by the fertilizer. With colored fertilizer its really easy to tell when the fertilizer is gone as you can see the color slowly fade as fresh water is mixed into the bowl. You need to be able to shut off water to the unit in order to add fertilizer, so its handy if the upstream valve is close to where you install the unit, but it won't hurt anything if you have to walk back and forth during the refilling to shut the water on/off. The unit has a plug on top, which screws out to let you refill without taking the bowl off. There is a dish in the black plastic top to help funnel the fertilizer down into the unit. I find that this is a really slow way to fill it up. The liquid tends to form an air seal over the hole, and you have to wait for it to bubble down and break the seal, which is pretty slow. I find it much easier to just take the whole bowl off, fill the bowl, and then put it back on the unit. These are quite tall, more than 1ft (30cm), so they might be difficult if you have a tight space where you want to use them. If so you might want to look a the options with smaller bowls, as those should be identical, with just shorter bowls. A full load of liquid fertilizer will be flushed out in two 15min drip watering sessions of 8 4ft/9ft (1.3mx3m) garden beds fed by 0.5gph 6in emitter drip line. I haven't kept close track, so it might go faster than that.
