## Description

desertcart.com : NEWTRY 0.4%-4% Fertilizer Injector for Drip Irrigation Adjustable Water Powered Dosing Pump 3/4" NPT : Patio, Lawn & Garden

Review: A great value and solid performer - Very good price and quality seems good for pricepoint. Has been installed and running fine for a few weeks now. No leaks and no issues thus far. Adjustments allow precise control for dosing, so I can set it at 250ppm and it seems to dose consistently. The added bits for connectivity seem to not be needed for anything, but do appreciate the fact they sent along a repair kit for any probable or eventual failures that may be common for this type fertigation option.
Review: So Far So Good - Built this fertilizer cart so we can move it around. Having great results using MasterBlend Tomato & Veg in a 2 bucket concentrate adjusting our pH to 6-6.5 at the plant. We are also using it to dispense a 2.5 ph acidic solution so we get our regular water to 6-6.5 pH at the plant. We have our pump set at 4%. My only question is how reliable is this pump.

### ⭐⭐⭐⭐ Works well until it doesn't
*by T***. on June 19, 2026*

mine worked great, until they didn't. I purchased one about 4 years ago and it worked well until it stopped. I tried repairs, greasing and other things that were suggested and it continued to function but it stopped working during the second year of use. It didn't get a lot of use, I only have a small garden. I had my system designed it use this unit and it did work ok while it did. In any case, I purchased another one (newer green model). This again worked well for a while then stopped pumping. I'll be looking for something else as a replacement.
