    Wilkins 14-ZWFR 1/4" Freeze Relief Valve

    Designed to prevent freeze damage to backflow preventers installed above ground in geographical regions subject to occasional freezing. The model 14-ZWFR senses water temperature and opens at 35°F to discharge near freezing water from the backflow device and draw warmer supply water through the valve. The model 14-ZWFR closes when water temperature reaches 40°F.

    Typical Installation: The Model 14-ZWFR should be installed on the downstream test cock or downstream attached piping of any backflow device installed above ground where freezing is a concern. 

    NOTICE: If the Model 14-ZWFR is installed on a test cock, the test cock must be left in the open position to allow the 14-ZWFR to function properly. The device is best suited to be installed in the vertical down position, but may also be installed at any orientation up to horizontal. Orientations above horizontal may cause an ice dam during operation and impair valve function. The device is not intended to replace the standard winterization process. 

    WARNING: Under freezing conditions the Model 14-ZWFR will discharge water from the outlet port. Provisions must be made to insure that discharge will not damage surrounding property or equipment. 

    Specifications: The Freeze Relief Valve shall be rated for 175 PSI. The body shall be cast bronze and the internal spring shall be 300 series stainless steel. The valve shall include a test cock and open at 35°F and close at 40°F. The Freeze Relief Valve shall be a ZURN WILKINS Model 14-ZWFR.
