Did you know the Deringer can be installed vertically? Deringer 20/20G and 30/30G (DC and DCDA) can be installed only vertical up, not down. The top lid and nameplate of the device must be pointing up in a horizontal application. You cannot rotate the device on its axis. Deringers 40/40G and 50/50G (RP and RPDA) cannot be installed vertically, only horizontally. #Backflow #BackflowPreventer #BackflowPrevention #Deringer #BackflowDirect #firesupressionsystem #firesprinklers
