Product Description
More Information
Dual Check with Atmospheric Port Designed for the Protection of the Water Supply from Carbon Dioxide Gas and Carbonated Water; These Substances Can Flow from Post-Mix Beverage Systems and are Very Acidic; If the Acidic Water Comes in Contact with Copper Tubing or Copper Pipe, It will Cause the Leaching of Copper Salts into the Water Supply; The Dissolved Copper If Ingested Can Cause Nausea, Abdominal Pain and in Some Cases Vomiting; The SD3 Prevents the Reverse Flow of Potentially Contaminated Water into the Potable Water Supply Due to Back Pressure Backflow and is Used for Continuous or Intermittent Pressure Conditions; The SD3 Atmospheric Vent Provides a Visual Indication of Failure in the Event that the Downstream Check Fails and System Backpressure Exceeds the Supply Pressure; ASSE 1022 Approved Dual Check with Atmospheric Vent; 316 Stainless Steel Body for Corrosion Resistance; All Rubber Compounds Comply with FDA Food Additive Regulations; Streamlined Body Design Minimizes Pressure Loss and Cavitation; Endurance Tested for More than 500,000 Pumping Cycle; Atmospheric Port Provides Visual Indication of Failure of the Second Check; Lead-Free
