Zurn Industries marked the tenth anniversary of its Zurn Wilkins 300 Series Small Backflow Preventer line with the newly renamed innovation, the EZSwap Pressure Vessel. For new construction plumbers and irrigation contractors, the EZSwap Pressure Vessel is removed and replaced with the flush fitting tool in seconds. Line flushing to remove fouling debris is fast, simple and safe. An easy single-person line flushing saves up to 15 minutes per unit. For backflow testers, the Zurn Wilkins 300 Series Tester Edition Backflow Preventer includes the additional advantage of fast-test cocks, speeding testing set-up and saving up to 35 minutes in repair and re-build time. For winterizing irrigation contractors, the Zurn Wilkins 300 Series Irrigation Winterizing Edition Backflow Preventer includes a blow-out accessory that replaces the EZSwap Pressure Vessel in seconds, allowing the contractor to hook up their air compressor to winterize systems and prevent costly freeze damage.
