Customer Questions & Answers

  • Question: What is the purpose of the Watts 9D Series 34 Brass Dual Check Valve Backflow Preventer?

    Answer: The Watts 9D Series 34 Brass Dual Check Valve Backflow Preventer is designed to prevent contaminated water from flowing back into the clean water supply. This device acts as a critical safety measure in plumbing systems, ensuring that water intended for drinking or other clean uses remains uncontaminated. It's particularly useful in residential and commercial properties where irrigation systems or commercial equipment could pose a risk of backflow. By installing this valve, users can protect their water sources from potential pollutants.
  • Question: How does the dual check mechanism work in this backflow preventer?

    Answer: The dual check mechanism employs two check valves in tandem, which create layers of protection against backflow. When water flows in the intended direction, both valves open, allowing unobstructed flow. If there’s any attempt at backflow, the first valve closes to prevent reverse flow, and if that fails, the second valve acts as a backup. This redundancy significantly enhances the reliability of the system, making it suitable for use in a variety of applications, including irrigation and plumbing systems.

    Answer: The Watts 9D Series 34 features brass construction for durability and corrosion resistance, dual check valves for superior backflow prevention, and a compact design that's easy to install in tight spaces.

To ensure your installation is compliant, it’s best to check with local plumbing authorities or regulations regarding backflow prevention devices in your area, ensuring that you meet all necessary requirements.
