Venturi Injection Tube with Bypass Valve for Drip Fertigation

Build a controlled fertilizer injection branch with a Venturi tube and bypass valve. Adjust the valve while the irrigation system is running to establish suction.

How it fits your setup

Combining the injection tube and valve keeps the main parts of a simple bypass together. Water flow through the Venturi draws a prepared liquid feed from the suction line when the available pressure difference is sufficient.

Choosing and using it

Check the assembly's connection arrangement against your line before ordering; tank, feed tube and backflow device depend on the wider installation. Test suction with water first, then set feed rate by measuring the stock solution consumed during a timed irrigation run.
