 The model ABF ASSE 1022 vented dual check back-flow preventer protects the connected plumbing and drinking water from the corrosive effects of CO₂ gas. The CO₂ gas mixed with water in a carbonator tank downstream from the back-flow preventer exerts backpressure on the discharge primary check valve on every pumping cycle. If this check valve becomes fouled and leaks, the CO₂ gas and water mixture will exhaust through the vent hose barb fitting. The secondary check insures that it cannot pass to the inlet or contact any brass or copper from the connected plumbing. The simple internal construction is easy to clean. It utilizes a lead free brass body and stainless steel discharge retainer. Under no circumstance is the CO₂ gas and water mixture exposed to the lead-free brass inlet or the connected plumbing.
