Zurn 114-375XL Lead Free Reduced Pressure Principle Assembly

The Zurn 114-375XL Reduced Pressure Principle Assembly is designed to be installed on the potable water supply lines of commercial or residential properties. This lead-free backflow preventer will protect against backsiphonge and backpressure which can lead to potential health hazards. The Zurn 375XL has been engineered for convenience by making the patented pressure vessel removable and gives top access to the test cocks. This assembly is not only lead-free, but also uses stainless steel struts, ball valve handles, and nuts.
