Can i buy an extra switch in my coach.???

The kit comes with a parts list so you can order replacement parts. You'll have to call the company to order an extra switch .

This is not a pump. It is only an actuator for your existing gate valve to the black and grey water holding tanks (you'll need one for each holding tank). The electric motor in the kit only opens and closes the valves by pressing a button in inside the RV instead of sliding the valve closed or open by hand at the drain location outside the RV. . If you drained you tanks by gravity, hand opening and closing the holding tank valve by hand, your tanks will still drain by gravity for the same hose distance to the sewer connection after installing the kit. If you want to pump out you tanks, you'l have to buy a macerator pump separately. I bought these electric valve kits for my black and my grey holding tank valves plus a portable Flojet macertor pump. The electric valves are permanently installed on the RV. But when I hook up my sewer connection at the campsite, I attach the macerator pump at the 4 in tank drain outlet. and connect the pump to a pre-installed 12v power connection near the tank valves. The switches for the valves and the pump are inside the RV. so I can drain my tanks from inside the RV, even in the rain or the middle of thenight.

What is this? I'm guessing a wiring extension kit sold separately from the Barker auto-drain? Description doesn't even say...

This is the Valterra auto drain actuator kit. It installs on a 1.5" or 3" Valterra drain valve and includes the actuator, switch and wiring necessary for installation.
