Typically, when your unit is winterized, the tanks and hot water are emptied; at least they should have been. What you need to do is connect a hose like you would to use fresh water and open the valve. Then go to reach faucet in your unit and open them, one at a time until the pink fluid goes clear and then wait another 10-15 seconds before closing. Once all faucets, shower and toilet have been purged of anti freeze, Make Sure the bypass on the hot water heater is opened to let water fill the tank before you turn on the power, for electric, to prevent burning up the heating element. Once all is done, you should be able to do the valve to have water directed into your fresh water tank. For future reference, the drain hose will be at a low point, under the belly with a valve. If the lever is online with the drain hose/tube, the line is open. Make sure the lever is perpendicular (90 degrees) to the line to be closed so you can fill the fresh water tank.

The water tank drain should have a shut off valve to prevent water leak. I wouldn't cap it, you should want to drain water tank on occasion.

You'll probably have to crawl under and trace where they go. You could possibly put some dye in one of the grey water tanks (ie: the kitchen sink drain or bathroom sink or shower drain) to figure out where it comes from. The black tank is your toilet drain. It always has the larger diameter pipe going to the valve (usually 2 or 3 inch diameter) The grey water tubing is usually 1 1/2 inch tubing.

Todd, hot water by-pass valves are usually installed behind the water heater. There are probably 3 valves that need to be operated.
1. - Close the cold water valve TO the water heater.
2. - Close the hot water valve FROM the water heater.
3. - Open the by-pass valve. It's the one between the other two.
