Review: Works fine! - So this is my first review, I WILL UPDATE over time especially if this fails. I had to return the first one that was sent by desertcart because clearly it was used, had ptfe tape and stripped threads. So my water pressure is 100psi going into the irrigation. This is wayyyyyy too much for this device. Yes it will leak EVERYWHERE! I am currently running it at 77psi using a zurn pressure regulator seems ok but it's probably passing the limits of the device. I do need the pressure though because there are just too many sprinklers on the lines. I mainly wanted this for 2 of my 3 stations which the lower pressure will reach. I have a bypass valve on there with a check valve, when I want to use it I will simply turn the valve off and on them switch it back. I have a bhyve app to control my irrigation, so I'll run it manually. I have no way of checking to see how accurate this will do the mic, but I can tell you when running it and you turn the knob you will see an increase in flow in the small tubing. Few cautions with this.... The threads are plastic. If you are going to be connecting this to an irrigation system make sure you know what you are doing. If you put the wrong threading on this you will mess up the threads. And you will get leaks everywhere. When screwing the cap back on don't just let it sit as you're screwing. Once you have the black part back on mostly lift it up and then screw with it in the up position so it can sit properly otherwise it will leak there.. This is using standard garden hose thread (mht and fth). This will limit the water pressure if you need higher pressure. Lower pressure you should be fine. I am using a 3/4 pvc pipe from my mains, to a regulator into a pvc ftp to 3/4" hose barb to a mht then to the device using Teflon tape and a hose gasket.... I'm going out of the device I'm pretty much doing the same thing. I also feel like this will probably handle more pressure and last longer than a regular hose, because of the gaskets they use. On the other side of the wall which is not pictured I have a regular hose bib so I can connect and fill up my watering can. This is another thing you can do. I also installed another hose bib in the back where the main line connects for the same reason. if you plan on just connecting this to your house and using it I feel it would be too excessive but obviously everybody has their own reasons. I wouldn't connect it directly to a hose bib. I would use a hose and make sure that it is seated correctly without any pressure on the connections... The only flaw of this device is the device is pretty much plastic. And they don't make it so you can connect it to an irrigation system easy. This is easily connected to a hose bib which is probably the worst way to connect this. They should have made this device with MIP threading and I'm just included a FPT to hose bib connection piece for those who would like to use it on a hose bib. I hope this helps anybody that buys this for the same reason I did. fertilization is very important especially if you grow fruits and grow flowers. I did want to use this to also lower the pH of my soil. I can use some hydroponic stuff or I'm sure there's other methods of doing it. But that was the other reason behind this. But otherwise I could just do it manually for now. Update 9.15.2020 The connection from the main line in started dripping because I barley hit it with a trash can. I couldn't get it to stop so I disconnected it. I placed a new gasket on it and used zip ties to really tighten it when as well as not letting the plastic slide off from it being tight. This seemed to resolve it. Also if using miracle grow, mix it. I filled the tank half way dumped the blue stuff in there and mixed it with a few oz. I also threw in some other stuff. To relieve issue when I'm done I purge the valve on the bottom for a quick second. Otherwise still good 4.20.25 Yes 5 years later. Been using it 3 times a year. So it did develop a leak at the top. Chapin replaced it. Still developed a leak at the top. I am at 77psi. So here's is my work around to this. I put my liquid fertilizer or pack of miracle grow. Tighten it up and turn the water on. It'll mix. Right before it reaches the top I turn the irrigation in for a full minute each station. I have it at the highest setting. At 30 seconds I switch to the next station until I'm done. Then I repeat the process till most the fertilizer is gone. However I'll increase the time to a minute and so forth. If you let it get to the top it will leak. Then I have it in the top tub for this reason. Hope someone finds this useful
Review: WASTE OF MONEY - At first it worked great. bought it on April of 2019 aka this year an used it at the beginning of every month. had a valve on it so it was not always hooked up to the sprinklers. for the last 3 months every time i go to use it. it leaks from the top gasket. that gets resealed multi times. so i did a water pressure test the water is running at 35 psi. then today when i decided to remove it all together the two black nipples on the main attachment. broke off. barely pulled on it enough to break it. this is poorly made. very disappointed in this product another company that had no pride in there product....

## Questions & Answers

**Q: Does this use incoming water to push out the solution, thus diluting it more and more as you go?**
A: Hi, yes water does go into the tank of the 4720 HydroFeed 2-Gallon Fertilizer Injector diluting the chemical as it flows. If we can help with any further questions, please feel free to call our Technical Customer Service Team at 800-444-3140 and they will be happy to assist you. Thank you for your question and for your business, we appreciate it. Chapin Customer Service

**Q: Will this fertilizer injector work on drip tape?**
A: Hi, the Chapin 4710 HydroFeed 1-Gallon In-Line Auto-Mix Fertilizer Injector System has a standard operation pressure of 40-60 PSI.  A minimum flow rate of 2 gallons per minute is required for the unit to function correctly.  If you have any other questions please give our Technical Support team a call at 1-800-444-3140, option 1.

**Q: Can this unit stay under pressure without failure? I want to install it before my 4 zone timer.**
A: Mine failed at 40 PSI after 5 days and made a big mess. I currently have a call into the company to see if maybe it was a defect in manufacturing because it is right along a seam in the plastic. There is nothing in the manual that says it can't be under constant pressure as long as it is 60 PSI or less... has anyone found an alternative in case Chapin comes back and says it is not meant for constant pressure?

**Q: It sounds like there is zero quality control during manufacturing. They even sent a person a used product. Why should I buy this item?**
A: Fortunately, I did not run into any issues with either the product/the manufacturer.  Sorry I couldn't help.

### ⭐⭐⭐⭐⭐ Excellent product. Fantastic customer service.
*by C***C on September 11, 2023*

It worked quite well in delivering the fertilizer to the irrigation, but then developed a crack and as a result leaked. Customer service resolved it right away. Now up and running no prob. I suggest isolating it from your main irrigation line with a diverter and valves - only allow water flow through it when you want to fertilizer. Will likely extend the life.
