The freezeless Model 17 anti-siphon protected outdoor wall faucet is designed and intended for year-round residential irrigation purposes regardless of outside temperature. This faucet will not rupture from freezing when the valve is shut off and the hose is removed. The model 17 contains an integral backflow protection device which protects up to 125 psi of backpressure and therefore does not require an add-on vacuum breaker. Round, powder-coated, die-cast aluminum handle. Woodford, The Choice of Professionals.
