Description
Watts F111603 is a 3" stainless steel reduced pressure zone assembly backflow preventer with NRS shutoff valves and an integrated flood sensor.
The manufacturer says it is compact, approved for horizontal installation in the direction of the flow arrow, and has a stainless steel body, torsion spring check valves, resilient seated gate valves, test cocks and a bottom mounted stainless steel relief valve. The maximum working pressure is 175 psi.
The integrated flood sensor uses SentryPlus Alert technology and needs an add-on sensor connection kit to send alerts. Backflow assemblies are regulated, so check local water authority requirements and testing rules before ordering.
