The directions say not to permanently mount it so its removeable. It just screws on like the lid to the pipe does. For me getting power to it wasn't hard. I have a 110V outlet on the same end of the house and just run the pump off a battery charger plugged into the house. However, it wouldn't be too difficult to just run a 12V power wire to the compartment my tank drain is in.
The pump runs off of 12V so in theory it could run off the compartment light although I'm not sure the wiring for the light could handle the amperage the pump draws.
