3/4 Inch Fertilizer Injector for Drip Irrigation Venturi Fertilizer Mixer Injectors Device Tube Filter

The media could not be loaded. This is a piece of a larger system. If you are trying to use this in the water hose alone, it is not meant for that and therefore will not work. The ends are not the correct threads for a garden hose, which should be the first clue. For about $15 in parts from your local plumbing or hardware store, and tutorials found online, you can build an excellent injector system that is sold through some of the other irrigation companies for $160+. I did it with zero plumbing experience and now I can sit on my porch and watch it work instead of mixing and spraying by hand. The only thing I would do differently next time is police unions on either side of the Venturi so that I can remove it easily to queen, and I would also put a shut off valve on the right side so that water does not backflow through the system when I want to just run water with no fertilizer.Since it is a suction system, it is reliant on a lot of variables including your water pressure and the output.I found that it would not run with one sprinkler because there was too much pressure on the lines and not enough flow over the Venturi piece, so I solved this by connecting two sprinklers to one another and this increased the output enough to gather suction.Eventually I would like to try to connect it to an actual drip system, but I’m not sure how to get past the problem of the pressure buildup in the lines causing a loss of suction. Otherwise, this is a cheap and very easy to operate unit, once you figure it out.

this product does not work at all. no suction even if you hold the liquid above the Venturi. Big waste of my time.

A little bit of a complicated review. I purchased this for use with a drip irrigation system. Every video I watched referenced how to use it for a sprinkler system and my brain did not put 2 and 2 together.First of all- notice that it has 2 male hose ends. Save yourself a run to the hardware store and get that worked out ahead of time. The product's threads are not NPT.Second- a sprinkler system does not build pressure and cause back flow the way a drip irrigation system does. This will cause your water to fill up your jug of pesticide or fertilizer or whatever. In my case, it was organic insecticidal soap.We initially set everything up with plain water and blue dye to make sure that the treated water came out of the furthest mister. Nothing. Nada. My jug filled up with water.I realized that there was no pressure forcing the treated water into the injector to allow the water pressure to siphon the rest as its supposed to. My husband and I removed the end screen piece and attached the hose to the nozzle of a pump sprayer. Turned the hose on; it filled the jug again. Turned it off then primed (pumped the sprayer full pressure) then turned the hose on, THEN released the nozzle on the pump sprayer. No go.Finally, I pumped for the life of me while he turned the hose on and KEPT PUMPING- sweet, sweet insecticidal soap misted my plants. The water in the siphon line still diluted my treatment some (insecticidal soap makes water a foggy yellow.) Thankfully, the siphon line is clear so we could see the difference.Eventually, we turned the hose to very low water and pumped like a mother until the insecticidal soap was pretty much the only thing coming out of the misters and called it a day..It DOES work for misters, you just have to get creative. Not wanting to kill my back spraying every plant just for the aphids to move over a row is a powerful motivator.Also, in a pressurized system like a drip irrigation system, it will blow the lines off of their attachments, so you pretty much have to leave it at 4 (which is wide open) and still zip tie the hoses to the flow adjuster.

This product DOES work for 10psi reduced drip irrigation. I have a 50’x50’ covered bed and used this injector with a total of 10 50’ drip tape rows with a 1/2” leader line. I also used a backflow preventer. The set up is like this: hose bib to timer, timer to pressure regulator (10psi), pressure regulator to 5ft jumper hose, jumper hose to back flow preventer+injector set up. I then have a 25ft garden hose that runs to the leader Line for the garden. The leader line is 50ft. So in all from the injector to the end of the leader is 75ft. Off of the leader line is the 10 50ft runs of 5/8 drip tape with emitters every 8 inches. The problem is not that the injector doesn’t work with reduced pressure! The problem is flow! Either you need a lot of drip system at low pressure or for smaller applications you must increase the water pressure to your drip system. But it will work! I was very scriptural after reading the reviews but I took a leap and I was thoroughly impressed. I was 1000% sure it worked by putting food coloring in water in a gallon jug and sure enough green tinted water on all ten of my 50ft drip lines. The key is rate of flow through the injector. You have to find the right balance to get it to siphon and then adjust the rate of injection at the supplied regulator on the hose. I set mine at the number 1 setting and had the perfect fertilizer to water ratio. Don’t give up there are tons of videos available on line to guide you. Thanks for reading!

Horrible product I have 50# pressure and it won’t siphon. No instructions no arrow pointing which way to hook it up. Typical Chinese made. Horrible quality!!! Don’t waste your time or money on this product. JH linden Michigan
