Anti-Siphon Adapter A compact hose-end backflow protection solution designed to help prevent outside water from siphoning back through the faucet. It fits standard outdoor hose faucets and provides a simple way to add anti-siphon protection to garden watering and drip-irrigation setups. The series uses a 3/4-inch female hose-thread inlet and male outlet, with thread combinations available to suit different market standards. Key Benefits

NEW Flowguard Check Valve Adapter The newly developed Flowguard is a one-way check valve adapter engineered for drip irrigation systems. It prevents reverse flow when pressure drops or irrigation zones switch, helping keep dirty or muddy water from moving backward into the system. By reducing backflow and back-siphoning, Flowguard helps protect emitters, filters and valves from contamination. Its high-impact ABS body is designed for operating pressures up to 100 PSI and flow rates up to 17 GPM. Key Benefits
