1/2" – 2" Backflow Prevention Devices
If you require a small residential backflow prevention device for your sprinkler system or other application, we've got a complete selection here from top-quality manufacturers such as Watts, Febco, Zurn Wilkins and others. Choices include double check assembly valves (DCA), pressure vacuum breakers (PVB) and 2-inch RPZ backflow preventers (reduced pressure zone). You have a choice of either leaded or lead-free, and we have valves in this category in 1/2", 3/4", 1", 1 ¼", 1 ½" and 2" sizes.
Select a half-inch backflow preventer valve, a two-inch double check valve, or a three-quarter-inch bypass device without ball valves. Simply click on the appropriate size valve you require and choose from the many configurations presented.
