Trouble with the water lines, pump, or tanks is one of the top complaints RV owners have. Fortunately, you can minimize your risk for these problems with proper maintenance and winter storage.
Be sure to empty your gray water and black water tanks every few days even if they aren’t completely full. Consider dumping ice into your black water tank every few months, right before a long trip. The ice will scrape off any solid deposits and then melt, allowing you to easily flush the tank when you arrive at your destination.
Pay close attention when hooking up and disconnecting your water hoses at each campground to avoid leaks. Keep your freshwater tank at least 3/4 full, but drain it and refill it every couple of weeks to keep the water fresh and flowing. Run your water pump every few days even if you have full hookups. Have your water pump and water lines inspected annually, and have any problems fixed as soon as possible. If you plan to store your RV for the winter season, ask your RV technician for a checklist on preparing for winter storage.
