Your cart is empty.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.

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.

The gasket that it comes with doesn't last and finding a suitable replacement is near impossible.This is the 3rd one we've purchased. The first one started leaking, the second one cracked and now the third one leaks as well. Not sure why the quality is so poor. Won't buy again.

This fertilizer/ pesticide disperser is terrific. I found the same problem that others found. The oring seal is terrible. Mine was pinched on delivery and I couldn’t find a match to replace it. I went to Home Depot and bought this gasket instead and it fits perfectly. Just drop it in ,screw the filter housing in, snug only. There’s no leaking at all and no finesse required. The gasket was about 4 dollars. I’ve only used liquid fertilizer (Miracle Grow) and liquid pesticide (Sevin dust). They were easy to use and very effective. Almost a 5 star but for the oring . Poor choice.

Mounted it on the wall, hooked up the inline, then the exit to the garden hoses. The right side leaked a little so I hand tightened it more and it quit leaking. I tried Teflon Tape at first but it wouldn't tighten properly. Took the Teflon Tape off and tighten by hand then a little bit with a pair of pliers. The System is on a timer setup. Since it is a 32 oz unit, I noticed the fertilizer would all be gone in about 32 to 35 minutes. Which means if it uses 1 oz of fertilizer per 1 gallon of water, then after about 32 minutes and 32 gallons, all should be gone and deluded just with water left. I use it on 3 different garden areas at the same time so all will be getting the same amount of fertilizer. I have found no issues with my unit. I love it.

I purchased this as I wanted to automate how I was fertilizing my garden and wanted to do it on a consistent basis. I was a little hesitant as there are not a lot of reviews for the product and the ones that are there are mixed. I took a gamble and have been satisfied so far.The quality of the product is very nice, surprisingly very robust. I had to get some fittings from Home Depot to make it work with my drip line (the unit is setup to accept garden hoses and you will need to adapt the threads for drip line. I did not have any leaks at all. I saw the YouTube video of the one guy reviewing this unit who said it leaked all over the place and returned it. Either he did something wrong or it was defective because I did not have the same experience, not even a drop of water. I did however use new brass fittings (to adapt for drip line) and did not use any Teflon tape or pipe sealant. Just threaded the fittings on hand tight and no leaks.How the unit works is a bit confusing and I had to e-mail the company for clarification. I initially thought that my concentrated fertilizer would be pulled up by suction into the drip pipe and the reservoir would draw down over time as the fertilizer is used up. This would mean that the concentration of fertilizer stays constant. HOWEVER... that is not how this unit operates (much to my initial confusion). What happens is that water pressurizes and replenishes the reservoir meaning that over time fertilizer gets diluted to the point where there is nothing in it. What this means is that if you are using this connected to a garden hose and manually watering your plants by hand, your first plant will get the strongest concentration of fertilizer and your last plant will get less. How much dilution depends on how long you run. A small garden it might not dilute for several watering sessions while a larger garden might dilute after one or two sessions. This isn't really a problem if you understand what is happening and just make certain you change the order of plants you water randomly from session to session to ensure the fertilizer is equally spread over time.In my case though, I used this inline with a drip system on a timer and the dilution isn't a problem as all of the plants receive the same concentration of fertilizer since they are all watered together through the same line. Over time the fertilizer concentration is diluted by water but you don't necessarily want to be hitting the plants with high fertilizer content daily anyway. So what I do is I fill the fertilizer once a week and let it dilute over time and then refill. In this application, it works well and I can already see my garden beginning to thrive.
