Review WATTS Backflow Relief Valve. 40xl-4150/210

The Watts F163725 Backflow Relief Valve, model number 40xl-4150/210, is a crucial plumbing component designed to protect your potable water supply from backflow contamination. This valve is specifically engineered to meet the requirements of the American Water Works Association (AWWA) and the National Sanitation Foundation (NSF) for backflow prevention.

The Watts F163725 is a double check valve, which means it consists of two separate check valves. The first check valve prevents backflow from entering the potable water system when the water pressure drops. The second check valve prevents backflow from entering when the pressure in the non-potable water system rises. The valve body is constructed of ductile iron, ensuring durability and longevity.

The inlet and outlet connections of this valve are threaded, with the inlet connection being 1-1/2 inches and the outlet connection being 1 inch. The valve is also equipped with a test port, which allows for easy performance testing, ensuring the valve is functioning properly. The test port is located on the top of the valve, making it easily accessible.

The Watts F163725 Backflow Relief Valve also features a manually operated test button, which allows you to simulate a backflow condition and verify that the valve functions correctly. This button is located on the top of the valve, near the test port. The valve is also equipped with a spring-loaded, diaphragm-operated mechanism, which makes it self-acting and eliminates the need for frequent maintenance.

In summary, the Watts F163725 Backflow Relief Valve, model number 40xl-4150/210, is a reliable and effective solution for protecting your potable water supply from backflow contamination. Its durable construction, easy-to-use test features, and self-acting mechanism make it a top choice for plumbing professionals and homeowners alike.
