The Watts 2 MAGNUM 40 KIT (RP) 2 1/2 W/ADAPTOR is a 2" reduced pressure zone (RPZ) backflow preventer with Grooved connections, approved for high health hazard protection. It is rated to 175 psi.

This 2 inch Watts Magnum™ 40 reduced pressure zone backflow preventer assembly kit includes a 2 1/2" Watts Magnum 40 with adapters to convert to 2" FNPT connections. It is designed to prevent health hazard and non-health hazard pollutants from entering the potable water supply system caused by backflow due to backpressure and/or backsiphonage conditions. Magnum 40 features integral Eccentric-Seal™ butterfly shutoff valves for a short lay length, and Dual-Action™ checks for high performance at low-and high-flow rates. It may be installed under continuous pressure service to protect against both backpressure and backsiphonage. Maximum working pressure is 175 psi (12 bar).

Common Questions

What hazard level is this RPZ approved for?

It is rated for high health hazard (toxic) cross-connections, so it may be used on either high or low hazard service. The assembly is listed to ASSE 1013.

Can this be installed on potable water?

No. This model is not certified lead-free, so it may not be installed in potable water systems in states enforcing the NSF/ANSI 372 weighted-average lead rule. Use it on non-potable service — fire lines, irrigation or industrial water — or order the LF (lead-free) version of this model for drinking-water use.

Does this assembly have to be tested every year?

Yes. This is a field-testable assembly with 4 test cocks. Most water authorities require it to be tested and certified by a licensed backflow tester at installation and annually thereafter.

Does the relief valve need a drain?

Yes. An RPZ relief valve is designed to discharge, and it can dump a large volume of water, so it must never be installed in a pit or below grade and the discharge must be piped to an adequate drain through an air gap. The air gap fitting is not included with this model and is ordered separately.
