Pressure Monitoring Capability Now Standard on Watts Large Diameter Series LF007 & LF709 Backflow Preventers

Share With:

Pressure monitoring capability is now standard on Watts large diameter (2-1/2 in. or larger) Series LF007 and LF709 backflow preventers with NRS gate valves for non-fire applications. Pressure monitoring can be activated on these valves with the purchase of add-on activation kits.


After activating the pressure monitoring system, users can access live pressure data with their existing building management system (BMS). Live monitoring provides instantaneous assessment of system pressure and check differentials, giving users immediate feedback on the performance of their backflow preventer. With constant pressure measurement, users gain valuable advanced warning of potential issues, adding a layer of protection to the potable water supply from potential backflow events. With the prevention of these events comes the benefit of avoiding the water waste that typically accompanies them.


Customers can also retrofit existing Watts valves with performance monitoring by ordering a sensor replacement/upgrade kit and BMS monitoring connection kit. For more information, go to
