Zurn Wilkins 400ST Backflow Preventer Series
June 21, 2018
Zurn notes its new Wilkins 400ST stainless steel n-Pattern Backflow Preventer Series focuses on the features that matter most to contractors, building owners and water utilities. Designed with a stainless steel body and smaller footprint, the backflow preventer withstands the corrosive effects of water and allows for direct drop-in replacement; it delivers convenience without compromise, the company adds.
