ROUTINE MAINTENANCE CONTINUED
DE-WINTERIZING
1. To de-winterize your motorhome, open all of the low point drains to allow the antifreeze
solution to drain from the water system.
2. Next, close the low point drains and connect your vehicle to the city water system. Put
water into the fresh water tank and pump at least one gallon of water through the water
pump to remove the antifreeze from the water pump. Keep the water heater in the bypass
mode.
3. As in the winterizing process, open the kitchen and bath faucets, inside and outside
showers, turning "ON" both the hot and cold water valves and flushing the toilet until the
antifreeze solution is flushed out of the system and the water flow is clear.
4. Once the system has been flushed, open the water heater bypass valve. Open the
freshwater tank supply valve from the pump and the ice maker valve.
5. Reinstall the water filter. Fill the water heater and hot water lines before turning the water
heater on.
6. Be sure to close the fresh water tank drain valves to allow the tank to fill.
