These heavy duty brass double check valves from Wilkins are designed to protect against both backsiphonage and backflow. Two independent check valves provide fail-safe operation preventing contaminated water from entering the potable water supply.
Both check valves face upward for easy maintenance and the entire assembly fits inside a standard municipal valve box.
These check valves are now lead free due to CA requirements and have increased in price.
