Zurn® Wilkins 3-475 Reduced Pressure Principle Backflow Preventer, 3 in, Flanged, Contains Lead
The 475 reduced pressure principle backflow preventers are utilized in high-hazard, potable water applications to protect against both back siphonage and back pressure. The model 475 is shaped in the N-pattern and is used in vertical flow up and vertical flow down applications, often for new or retrofit installations in compact spaces. Its single access cover reduces maintenance down time and repair costs. Alternatively, the model 475V is shaped in the Z-pattern and is installed in vertical flow up applications. Both model are equipped with the patented, center stem guided compound check for low headloss, superior reliability and unmatched performance.
