400 Series - Anti-Siphon Wall Hydrant

The 400 Series is similar to Mansfield’s original patented vacuum breaker design, now manufactured by Prier in Kansas. The 400 Series provides year-round water to areas of structures that are prone to freezing, with the added protection of an anti-siphon device and backflow preventor. The hydrant valve is connected to the supply piping in the heated portion of the structure, eliminating the possibility of freezing. The valve is approved to ASSE, IAPMO and CSA standards. The 400 Series is a “Smart-turn” design, 180 degree opening and closing, for easy operation and flow control. The Mansfield 400 Series is made in sizes from 4” to 14”, in 2” increments.
