Watts 0061970 Preventer
The Watts 0061970 9D-M3 backflow preventer is a professional-grade dual check valve designed for continuous pressure applications in commercial and residential settings. Certified under ASSE 1012, this 1/2 inch backflow preventer with vent effectively isolates the domestic water supply from non-health hazard contaminants. Its forged brass body and stainless steel internal components provide superior durability when installed on boiler feed lines, processing tanks, or laboratory equipment. The Watts Series 9D mechanism utilizes a primary check with rubber-on-rubber seating for a bubble-tight seal and a secondary check with rubber-to-metal seating for maximum reliability. In the event of secondary check fouling, the intermediate atmospheric vent discharges leakage safely to protect the system. Featuring female union inlet and outlet connections, this valve is engineered for easy maintenance and simple removal from the line. It supports operating pressures up to 175 psi and temperatures up to 250°F, making it a versitile choice for high-performance HVAC and plumbing systems.
Key Benefits- Enhanced Contamination Protection: Dual check design with an intermediate vent ensures that polluted water cannot re-enter the potable supply during backpressure or back-siphonage.
- Durable Construction: Built with a rugged brass body and corrosion-resistant stainless steel working parts to withstand harsh system environments.
- Flexible Installation: Compact design allowing for either horizontal or vertical mounting to accommodate tight equipment headers.
- Simplified Maintenance: Equipped with union-style connections and an integral strainer to permit fast servicing and protection of internal check modules.
- Optimized Flow: True line-sized construction minimizes pressure drop while allowing debris to pass more freely, reducing check fouling.
Can the Watts 9D-M3 be used in high-hazard applications?
No, this model is specifically designed for non-health hazard applications. For high-hazard cross-connections, a Reduced Pressure Zone (RPZ) assembly is typically required by local codes.
Is this backflow preventer suitable for hot water boiler feeds?
Yes, the Watts 0061970 is rated for temperatures up to 250°F (121°C), making it ideal for standard boiler water make-up lines.
Why is water dripping from the atmospheric vent?
Occasional dripping occurs during normal pressure fluctuations. However, continuous leaking usually indicates debris in the second check valve or a need for a repair kit.
