Dual Check (DUC)

Dual Check (DUC)

The DUC consists of a lead free cast copper construction, with two plastic replaceable check valves, and stainless steel springs. This is a non-testable device that is designed for low hazard residential water system containment in a continuous pressure application. The dual check is installed immediately downstream of the residential water meter, generally in a horizontal position. Configured with a meter connection nut (MCN) at the inlet, it is designed to thread directly onto the outlet of the water meter saving one connection in a residential water meter setting.

  • Available connections: 5/8”, 3/4",1” water meters.
  • Low pressure loss through device.
  • Industry lay lengths for easy replacement.
