De-Winterization Procedure


It’s spring time in the Rocky Mountains and everyone is getting ready to hit the road with their RV’s, Travel Trailers, Fifth Wheels, and Truck Campers. In order to get ready, you need to de-winterize your unit for the season. Here’s our step-by-step instruction to make sure your de-winterization goes off without any issues. NOTE: It is the customer’s responsibility to fully research and understand their RV. Big Sky RV is not responsible for damage of any kind. Also, your manufacturer warranty does not cover freeze damage. Refer to your owner’s manual or consult with a Big Sky RV service consultant if you find any water damage.

De-Winterization Procedure

1. Locate your water heater door. Image below



2. Make sure your drain plug is inserted and tight in your hot water heater. 



3. Make sure water pump winterizing valves are set for normal use. If you're not sure which way is normal flow, use this picture as a point of reference. Valves are OPEN when turned parallel to water line, and CLOSED when turned cross ways.



4. Switch the hot water tank valves from blocked back to flow. Our Jayco and Starcraft  products have a by-pass for this. If your unit does not, consult a Big Sky RV service or parts employee for by-pass options. This image shows how valves should be set for normal use. 



5. Close all gate valves. Uncap sewer connection and connect sewer hose to trailer and to dump station.



6. Close low point drain on fresh water tank. 



7. Connect water supply or fill fresh water tanks and turn on water pump. 




8. Open faucets one at a time and run them until your water supply is clean. Antifreeze is indicated by color (usually pink) and foam in the water. Make sure to run both hot and cold on each faucet. Don't forget your less used faucets like your outdoor shower. 
9. Flush the toilet until the water appears clean. 
10.  Dump holding tanks by opening your gate valves.  When empty, close gate valves, remove sewer hose and replace sewer cap.
Your RV is now de-winterized!

Other Spring Tips:
  • Inspect and clear tubes of any blockage on water heater.  This can be caused by wasps or spiders.
  • Install new batteries in the smoke detector and carbon monoxide detector.
  • Check LP Gas/Propane detector by pressing the test button.
  • Check the roof for any damage and/or cracked caulking around vents, antennas, rear and side roof moldings. If you have a rubber roof, check your owner's manual for cleaning instructions.
  • Check for cracked caulking around windows, doors, and side moldings.
  • Clean the inside of the air conditioner filter, they are washable.
  • Check the refrigerator roof vent to verify there is nothing blocking the vent. Birds have been known to make nests behind or in the vent.
  • Visually inspect the air conditioner unit from the roof. Make sure the fins are clean and straight.
