I need to install a Backflow prevention device on my water line on my side of the meter per my city code... I have 1 1/4 "pvc as my water line, Do I have to install this size Preventer or could i go to a 1" device. I plan on installing like a watts 900 or maybe a zurn-wilkins model. But the bigger the device they are quite a bit more expensive...........
