Zurn Industries 112-350XL

The 1-1/2'' 350XL Double Check Valve Assembly is used in low health hazard, non-potable water applications for protection against both backsiphonage and backpressure of polluted water. A favorite for plumbing contractors, the patented and innovative EZSwap removable pressure vessel allows for simple, cost-effective maintenance and repairs, straightforward line flushing, quick winterization, low-lead law compliant design, and added water savings. Its stainless steel shut-off valve handles, hardware, and struts are corrosion-resistant and the durable UV resistant reinforced nylon EZSwap Pressure Vessel resists corrosion and mineral build-up to better withstand harsh outdoor conditions.
