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.
