Pressure monitoring capability is now standard on Watts large diameter (2 1/2” or larger) Series LF007 and LF709 backflow preventers with NRS gate valves for non-fire applications.
This manual provides the user with the information needed to understand what degree of hazard or potential risks exist to potable water systems, and whether the proper backflow prevention method, device or assembly has been selected and correctly installed.
For the second year, National Backflow Prevention Day on August 16, 2022, recognizes the role of backflow prevention and cross-connection control and those who install, maintain, and test backflow preventers.
