Product details

About the Watts 1 LF909QT Backflow Preventer Reduced Pressure Zone Assembly Lead Free 1" A brand of Watts Water Technologies, Watts Regulator Company is an innovative manufacturer of water quality products for your plumbing needs. The Series 909 Reduced Pressure Zone Assemblies (Part # 0391009) are designed to provide superior crossconnection control protection of the potable water supply in accordance with national plumbing codes and containment control for water authority requirements.Why choose the Watts brand? For the simplicity and of course our low cost to you This series can be utilized in a variety of installations, including health hazard crossconnections in plumbing systems or for containment at the service line entrance. With its exclusive, design incorporating the patented airin/waterout principle it provides maximum relief valve discharge during the emergency conditions of combined back siphonage and back pressure with both checks fouled. Sizes 3/4" and 1" (20 and 25mm) shutoffs have tee handles. How it Operates: The unique relief valve construction incorporates two channels: one for air, one for water. When the relief valve opens, as in the accompanying airin/ waterout diagram, the righthand channel admits air to the top of the reduced pressure zone, relieving the zone vacuum. The channel on the left then drains the zone to atmosphere. Therefore, if both check valves foul, and simultaneous negative supply and positive back pressure develop, the relief valve uses the airin/waterout principle to stop potential backflow.
