Does this use incoming water to push out the solution, thus diluting it more and more as you go?

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

Will this fertilizer injector work on drip tape?

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.

Can this unit stay under pressure without failure? I want to install it before my 4 zone timer.

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?

It sounds like there is zero quality control during manufacturing. They even sent a person a used product. Why should I buy this item?

Fortunately, I did not run into any issues with either the product/the manufacturer. Sorry I couldn't help.
