DISCONTINUED - The manufacturer of our Backflow Prevention Valve (MLF-31) is no longer going to produce these. We have decided not to replace this device and are suggesting that you purchase a much higher-quality device made out of brass like the one sold on Amazon titled "Eastman 3/4 Inch FHT x 3/4 Inch MHT Hose Bibb Anti Siphon Vacuum Breaker, Brass Plumbing Fitting, 20199".
