Welcome back Sam! To add an electric black tank dump valve to your Sprinter, I recommend the Valterra item # VAL45MB. This is a 12v motorized system that is designed to replace a manual sewer valve. It'll allow you to dump your waste tanks with the flip of a switch.

The Valterra E-Valve Electric Waste Valve item # VAL45MB has male spigot ends that insert into 3" sewer pipes. It comes with a wiring harness and switch panel that can be mounted in a convenient location on your motorhome. There's also a light on the panel that comes on the entire to the valve is opened so you can be sure to close it.

What kind of trips do you typically take in your Airstream Grand Tour van and where do you usually empty your waste tanks? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
