We get asked a lot “What’s the difference in the Premium and Pro-Series valves?” The actual valve is the same physically so no additional installation steps are needed to interface with your existing plumbing. The difference for the Premium electric waste valve versus the Pro-Series is in the actual operational flexibility. The Pro Series valve is easier to connect the power 12vdc because it is done at the valve, not at the switch. The switch interfaces with the controller through a small easily run cable (RJ 11) much like a telephone land line wire and has both a Green light indicating Closed and a Red light when the valve is Open, so you always know the status of the valve. In addition the controller on the Pro Series has 2 ports so an additional switch can be added OR it can be connected to a computer. The future of RV Waste Management is to automate the dumping process and the Pro Series is ready to go.
