Chemigation/Fertigation Design & Optimization with Mazzei® Venturi Injectors 

Thank you so much for posting this. I was so lost with which injector to get & this info made it doable.

I tried to register twice with your company so I could use your injector calculator to determine which of your injectors that I need. After trying twice I gave up and bought a different brand because if your injectors work as well as your website then It would have been a grand waste of money.

my system does not seem to suck any water at all from the 35l bucket put . i used method 2 with pressure rec valves. Upstream is 2-4 BAR depending on how many blocks I open. Downstream i put a pressure reducing valve at 1 BAR. because of the downstream dripper lines . could that effect it. The venturi is horizontal , on the upper 25mm bypass pipe the valves down on the main 25mm pipe

Hi, may I know how do I reduce the outlet pressure?

I noticed that all videos of venturi injectors are in a horizontal position. Do they work in a vertical position??

can i use this for the car wash foaming ? with thick foam ?
