Install a water filter on the fresh water intake hose to prevent sediment from settling in the hoses and tank.
Add water to the gray and black water tanks when not using the RV. This will stop the dump valves from drying, especially if the RV has been parked in the sun for an extended period.
Fill the fresh water system with 3/4 cup of bleach for each 50 gallons of holding storage. Allow the solution to stand for a few hours and then thoroughly flush the system with water. This will help sanitize the system. Take care not to leave any bleach in the tank as it could cause damage to the pump.
Check the RV electrical panel if the water pump does not run. Make sure to replace fuses with others of the exact same amperage. Make sure that the pump is turned on and check that the battery has a charge.
Leave the drain valves open and wait until the black water tank is full before dumping out. This way the force of the full tank will easily flush out any solids from the tank. With the valves left open, the solid waste could collect in the bottom of the tank and cause obstruction problems.
