    Tips to Winterize your RV

    It won't be long before winter is here and you begin to put your RV's to rest for the season.  But before you send them off to storage there are a few things you have to take care of first. Here is a detailed list from the KOA about how to get your RV ready for winter. 

    Winterizing Checklist:

    • Non toxic RV antifreeze- 2 to 3 gallons is usually enough
    • Water heater bypass kit
    • Wand to clean holding tanks
    • Water pump converter kit, or tubing line to connect to inlet side of water pump
    • Hand tools to remove drain plugs

    Once you have all your supplies complete the following steps: (refer to owner’s manual for location of all components)

    1. Remove and bypass the inline water filters
    2. Drain your fresh water holding tank
    3. Drain and flush both the black and gray holding tanks (products like Flush King will clean both)
    4. Lubricate the termination valves with WD-40
    5. Drain the water heater by removing the drain plug and opening the pressure valves
    6. Open all faucets including ones in the shower and bathroom
    7. Locate and open the low-point drain lines.  You can turn the water pump on to force all water out but be sure to turn off once drained
    8. Recap all the drains and close the faucets
    9. Bypass the water heater- if there is no bypass kit the water heater will fill up with antifreeze before making its way through the water lines, wasting 6 gallons of antifreeze
    10. Install the water pump converter kit, or disconnect the inlet side of the water pump
    11. Connect a clear tube to the inlet side of the water pump and insert the other end in a gallon of antifreeze
    12. Turn the pump on and pressurize the system, turning on all the faucets starting with the closest. Flush the toilet until antifreeze appears. Once the antifreeze appears, turn the pump off and open a faucet to release the pressure.
    13. Go to the city water inlet located outside your unit, remove the screen and push on the valve with a small screwdriver until antifreeze appears.  Replace the screen.
    14. Pour a cop of antifreeze down each drain and pour 2 cups into toilet and flush into your holding tank.
    15. If your water heater is electric, make sure it is unplugged and turned off.
    16. Make sure all faucets are closed and you are done!
