Replace or build the injector branch of a drip fertigation setup with a Venturi injection tube. Match its joints to your bypass pipework.
How it fits your setup
This tube forms the water path through which a Venturi can draw liquid feed from a stock container. It is intended for a compatible injection assembly, so the surrounding valves and pressure conditions matter as much as the tube itself.
Choosing and using it
Check the actual PVC connection dimensions and orientation against the existing bypass before cutting pipe. Confirm the intended suction port and tubing fit, install upstream backflow protection and test the assembly with clean water before drawing fertilizer.
