I am assuming you have the four valve water control panel.

First thing woould be to make sure you have completely dumped your holding tanks.

Now I set the valves to the drain setting and open all faucets, remember the outside shower, commode and commode water hose. This should get rid of your water in line. I leave it like this for several hours. While that is draining, I throw the WH bypass. The direction the valve handle points is the direction of water flow. Take a close look. There may be two bypass valves on your system. After throwing the bypasses, I remove the WH stoppor (outside), set it aside (inside the WH compartment). If you have an under sink or in house water filter, there should be two bypasses. One on each end. Throw those. Remove the filter and order or pick up a replacement. I do this now so I don't forget and have the replacement under the sink when I dewinterize. If you make the mistake of not bypassing the water filter, when you proceed to the next steps, you will not see pink. Don't task how I know. By now you are ready to run pink through your lines. As others said before, on the right side of you water control panel is a small, removable plug. Remove it and attach the small hose that should have come with it. If you do not have that small inlet tube to attach, call your nearest Coachmen dealer or RV parts dealer. Most will know the size. Make sure all faucets are off. Once the inlet tube is attached, set the control valves to the winterize settings, place the inlet tube in a gallon of the pink and turn on your pump. While pump is on, open each faucet, one at a time, until you run some pink down the drains. Don't forget the outside shower, commode and commode water hose. I even throw it back to drain for a second to flush pink into the every piece of the line. This should take just about a gallon of pink. Pour a little pink down the tub drain and commode to make sure there is a bit in the bottom of each holding tank.

You are done!
