Review: Works well, great value for money. - I have used Dosatron systems in my greenhouse for years. I needed to order some parts, so I grabbed this injector as a full in until my parts arrived. It came and set up was easy, came with a rebuild kit and extra parts, all things I would have to buy separately from dosatron. It has been up and running smoothly for a week. It works so well I will leave in use unless something stops working. I will update review if that’s the case. Also seems to leak less than the dosatron, I believe this is because they include a wrench for the top.
Review: Quality at a good price! Wish it had a bypass valve built into the design. - I purchase the Newtry fertilizer injection system to feed the flower garden growing around our household. It works as reliably as my neighbors $500 injection system in his commercial greenhouse! To winterize the system, I simply removed it from it's mounting bracket and brought it indoors. Next spring, I will change the plumbing to create a bypass line around the injection pump. It would be nice to have an internal bypass valve for those times when you want to wash a vehicle.

### ⭐⭐⭐⭐ Important advice
*by K***K on June 28, 2023*

Great value unit. Will do exactly what it's supposed to do. Make sure to read directions and follow this advice. Plastic is not as UV resistant as more notable brand, plan to mount or store in full shade/dark, no sunlight. If mobile unit only bring out while using, store in dark. Scale on ratio adjustment isn't accurate. Must use TDS meter for precision. There is a max pressure. This is important. You may need a pressure regulator and PORV in addition to screens and check valves. See photo for 2 year old unit mounted in a controlled environment green house, previously subjected to 90psi operating pressure and 110psi surges. The case split. Unit on right installed 1/23 (along with regulator and porv) to replace split unit from 7/22. Unit on left, split, yet to be replaced also from 7/22.
