Mazzei 1078 (1") Injector - WMX325

$79.99
  • Qualifies for $11.99 per package flat rate shipping in the Continental US.
  • In stock. Ships from our warehouse in Northern California.

Use this model if your flow rate is between 5.5 to 26.8 gallons per minute. Low-cost, accurate injectors are capable of higher flow rates than the other injectors we carry. They require a bit more installation expertise, but the cost savings can be worth it.



Injector works using pressure differential to create suction, pulling the fertilizer concentrate steadily into the main stream of water. Injection rate depends on the pressure and flow rates. Made from polypropylene with a 20% glass fill, built to last, and no moving parts to wear out. Choose the one that matches the minimum flow rate of your irrigation system, not your pipe size. Instructions for assembly are included.



Assembly kits are available for easier installation.
