Dual Check (DUC)

Dual Check (DUC)

The Dual Check (DUC) is a non-testable backflow prevention device designed for low-hazard residential water system containment under continuous pressure. It features a lead-free cast copper body, two replaceable plastic check valves, and stainless steel springs for reliable performance.

Installed immediately downstream of a residential water meter—typically in a horizontal orientation—the DUC includes a meter connection nut (MCN) at the inlet, allowing it to thread directly onto the outlet of the meter. This configuration eliminates one connection in a standard meter setting.

Features:

  • Lead-free cast copper body
  • Two plastic replaceable check valves with stainless steel springs
  • Installed downstream of water meters in horizontal orientation
  • Available for 5/8", 3/4", and 1" water meters
  • Low pressure loss through the device
  • Industry-standard lay lengths for easy replacement
