To Elkmont Owners w/conventional toilet

We use a product called Sewer Solutions to drain our black water tank. It uses a high pressure water jet to totally macerate the black water tank contents w/no mess or odor.

However, we're planning on trying out dry camping for the first time and have purchased one of those black water kits w/hose and accordian. Our question is how do you flush the tank/hose thoroughly after it's drained?
