Awesome! This answered my question. I have one of these and love it but only used it with a high pressure system. I have had to prime it before like you did. Was looking to use one with low pressure system. I'll give it a go.
Sure, I am absolutely guessing on the concentration of fertilizers with an eye on being conservative. I also amend my beds with several non liquid fertilizers in early spring
I made two of these for my raised beds. I have them attached to digital hose timer. They both seem to siphon water from my bucket but when the water turned off the water flows out of the siphons tube. I dont have the 2 ball valves on the sides is that necessary? Also do you keep your water on? To be clear my set up is in this or from the water source: Anti siphon valve Venturi loop Drip filter Drip timer
My water source is an IBC tote so my setup is gravity feed only. I intended to inject liquid fertilizer manually and not on a regular timer automagically. I don't thnk the two ball valves are completely necessary, but they offer more control of the flow.
From what I understand if you close off your main valve so that it flows through your horseshoe, then instead of fully opening the right valve when viewed, only open it halfway which creates the pressure differential or suction. Opening it fully may create small amount of suction butt I'm curious if opening a halfway or 3/4 of the way while leaving the left horseshoe valve fully open makes a difference. Wouldn't hurt to give it a try.
I am thinking about making one of these but the problem I see is that you have to manually start the siphon every time. I have an automatic timer that waters my garden and don't want to have to go out there and start the siphon myself. How has it been going for you? Have you added or changed anything?
Hey Plant-Based Prepper! The way I think about and use the injector is that it is not meant to be an automatic process. You only fertilize periodically, so I only setup the injector when needed, the rest of the time, the injector is detached from the irrigation system. If you want to have it automatic, I see no problem with that. You will just need a ginormous bucket or trash can full of liquid fertilizer (water soluble mix) and setup the injector, siphoning once to get it started. It should work as long as you have liquid fertilizer in the container, since the vacuum should be maintained, since your automatic shut off should be close to the water source hose bib. I have only used the injector with the gallon milk jugs, my goal was to use the injector for corn, but I didn't get the opportunity to plant corn this year. I like the injector, particularly since my source is a gravity fed IBC tote. I wasn't sure it would have enough flow from the tote to pull the fertilizer from the jug, but it does! If you have a well or city water source from your house, you are better setup than I am. Good Luck!
to get the siphon to run by it self the main valve need to be left slightly open this will cause a lower pressure on the left side of the setup boosting the siphon effect
I use the 1/2" landscape irrigation tubing for the in-bed main line and then drip tape in the beds. I don't glue any of the fittings and have not had a problem so far.
I don't think you had suction (sufficient). When you sucked liquid through the tube you created a gravity feed which allowed the liquid to flow into and through the Venturi. ruclips.net/video/WP1OpRTRGoI/видео.html

Crossing my fingers!
So my question would be, wouldn't you need to make the fertilizer a higher concentration to get a proper amount to the plants?

Thanks, headpainter1! I'll def give it a try

Very good system. Maybe you could add 7mm check valve at the silicon hose to prevent to siphon everytime you need to add the Fertilizer 😊
to get the siphon to run by it self the main valve need to be left slightly open this will cause a lower pressure on the left side of the setup boosting the siphon effect
Can I use this with 1/2" landscape irrigation tubing? Would that affect any of the sizes of PVC fittings? Is it necessary to glue it? Any updates?

Hi, what is the size and the name of your injector
Mazzei (287-PP) Gas/Liquid Injector - Polypropylene Black 1/2" MNPT
I don't think you had suction (sufficient). When you sucked liquid through the tube you created a gravity feed which allowed the liquid to flow into and through the Venturi.
