Watts Brass Tubular 1X1 LF7RU2-2 Backflow Preventer 1 in

Product Description

The WATTS BRASS TUBULAR 1X1 LF7RU2-2 is a 1-inch lead-free residential dual check valve backflow preventer designed to protect potable water supplies from contamination caused by back-siphonage or backpressure. It features a union female NPT inlet and female NPT outlet configuration, making removal and reinstallation straightforward during routine service. The lead-free construction meets modern drinking water standards, and the dual check design provides two independent barriers against backflow. Plumbers install this fitting on residential water supply lines where backflow protection is required by code.

This backflow preventer is suited for residential plumbing applications where a compact, in-line dual check device is required. The 1-inch port size accommodates standard residential service line sizing. The union inlet connection allows the valve body to be removed without cutting pipe, which is a practical advantage in tight mechanical spaces or for periodic inspection. It is typically installed on supply lines serving fixtures, appliances, or irrigation zones that require a cross-connection control device.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC cross-connection control requirements. Shut off the water supply and relieve line pressure completely before removing or installing this valve. Apply thread sealant or PTFE tape to all male NPT threads and tighten to hand-tight plus wrench-snug — do not overtighten threaded plastic or brass fittings. Verify flow direction and confirm the inlet union nut is fully seated and leak-free before restoring service pressure.
