Backflow Preventer Retrofit/Upgrade (all machine types)

• Previous versions of the backflow preventer were non-vented and compliant to ASSE 1032. The updated part includes a vent, and is compliant to ASSE 1022.
• The updated backflow preventer is located in the same place as the old part, and should not change the routing or functionality of the water path in the machine.
