Product Details

Zurn Industries 1-375S

The 1'' 375S Reduced Pressure Principle Assembly with bronze wye type strainer offers high hazard protection against backsiphonage and backpressure in non-potable water applications. Most often used by irrigation contractors, the top benefits of the 375 are its low lifecycle costs and the innovative EZSwap Pressure Vessel that saves you 15 minutes in repair and rebuild time, provides straightforward line flushing and quick winterization. Built with the same functions of our 975XL model, the 375 can be used in the highest corrosive water environments.
