Wilkins 720A 1 inch Pressure Vacuum Breaker
SKU: 1121
$67.20
The newly designed 720a strategically positions the test cocks so that it is easier to install in either direction. The new 720a can now be installed as a direct replacement for the 420a . The Wilkins 720A has a built-in relief valve that will allow expanded water to escape the cavity of the valve as water temperature falls, allowing additional time to properly winterize and insulate the Wilkins 720A pressure vacuum breaker.
