Fertilizer Injector Tube, Irrigation Venturi Fertilizer Injector, 1/2" 3/4” 1” Inch Agriculture Garden Fertilizer Mixer Injector Agriculture Tool Plastic Black(1 inch)

Works perfect for my bubbler

Has one job and doesn't do it. The check valve ball is free, the water just pushes past it. No matter which direction you hook it up, there's no suction generated by the Venturi port

My flow rate was too small for this to work. One needs much more feet of drip tape to allow sufficient GPM for it to suck up the fertilizer solution. What that mystery number might be is unknown to me. 3 stars for not working , it probably will work for a larger garden.

Threads are BSP, not NPT. Make sure to double check. I didn't. I'm sure the product works fine, but now I'm stuck trying to find fittings.

So I had watched a few videos on how to install this correctly and use the injector tube. Currently I am still unable to get it to work correctly. I believe it does work but from me I've been having trouble setting it up I guess correctly. Hi make sure the water flow pressure is enough, and made a little bypass PVC set up with on and off valves in order to bypass or not but I pass this fertilizer injector tube. At this point I would be hesitant to recommend but will update shortly.

even with a gravity assisted setup, only tablespoons a minute are drawn into the system. I added a pump and use it as a check valve. it works for that.

This is not a common American fitting. Since it’s British straight pipe, a normal NPT adapter will not work and it will leak or fail. This is what happens when suppliers don’t research their market

used it for 5 emitters and the vacuum only works on the initial start up.

El material es muy frágil y no cumple con las especificaciones

Exactly as advertised. Shipping was quick and it met all my needs.

Using it to inject ozone into my cold plunge. Works perfectly.

This does not work. Not only does it not produce suction but it frequently jets water out of the inlet port and forces water with such force that it has ruined two check valves. Absolute garbage.
