Review on 🚗 Efficient Auto Drain: The Barker Valterra-Bristol Model by Justin Kautzman

Installation took about 1/2 hour. Started by installing the motor on the mount. Then he unscrewed the handle on the valve and screwed the bracket with the motor to the valve with the available screws. Finally, an adapter is screwed on, which actuates the valve with the motor. The electrical part wasn't that easy as the wires aren't very long. About 4 feet long. I had to splice and add another 5 feet of wire so I could place the switch on the compartment door. Also, cable routing has been added around the cables for a tidy look. Have it installed for both gray and black tanks. Used several times. Love it.
