Operates at 0.09?11 GPM with standard 3\/4\" NPT connections.\n- Water-Powered Design for Flexible Installation: A fully water-driven injector?perfect for fields, barn lines, detached greenhouses, or backyard systems where power is unavailable. Proportional mixing remains steady even when flow or pressure fluctuates.\n- Stable Performance With Precision Engineering: The enhanced cylinder-and-piston mechanism provides uniform mixing for liquid fertilizers and soluble treatments. A dependable option for hydroponic setups, nursery operations, livestock watering systems, and general dilution tasks.\n- Versatile for Everyday Growing Needs: Suitable for greenhouse feeding, raised-bed gardening, and crop nutrient delivery. Designed for growers who need repeatable results across different irrigation layouts.\n- Usage Guidelines for Optimal Results: Each injector is water-tested before shipment; moisture on arrival is normal. Use solutions within pH 5?9, follow the flow-direction arrow, and keep operation between 2.9?87 PSI. Normal operation produces a rhythmic clicking sound; if unusual noise appears, apply lubricant to the sealing ring. For liquid use only, not for gases.\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003eMore Choices\u003c\/p\u003e\u003cp\u003eCan it be used with an impact sprinkler system?\u003c\/p\u003e\u003cp\u003eDoes it fit a normal garden hose?\u003c\/p\u003e\u003cp\u003eIs this a Venturi?\u003c\/p\u003e\u003cp\u003eHow to adjust the ratio?\u003c\/p\u003e\u003cp\u003eHow to use the exhaust valve?\u003c\/p\u003e\u003cp\u003eCan it be used with an impact sprinkler system?\u003c\/p\u003e\u003cp\u003eYes, it can.\u003c\/p\u003e\u003cp\u003eDoes it fit a normal garden hose?\u003c\/p\u003e\u003cp\u003eNo, they are pipe thread fitting, you need 3\/4 pipe thread to hose thread adapter.\u003c\/p\u003e\u003cp\u003eIs this a Venturi?\u003c\/p\u003e\u003cp\u003eNot a Venturi.
