Get Ready to Winterize!

Get Ready to Winterize!


Before you pack it all in and put your RV away until spring or summer, there are several things you need to do in order to keep your home on wheels in tip-top shape! We have a list to help you with winterizing and making it a breeze! 

First up is the plumbing system. This is more than just making sure your tanks are empty. Make sure you do any of the following that you can: 

  • Drain the fresh water tank. This does not need to be flushed. 
  • Drain and flush the gray and black tanks. Make sure you lubricate the termination valves with a little WD 40! 
  • Remove and bypass any and all filters.
  • Drain the water heater and remove the plug and open the pressure relief valve. 
  • Open all water faucets, including the toilet valve and outside shower (if your RV has one) to drain any water.
  • Find and open the low point drain lines. There will be two--one for the hot and the cold water lines. If you use the water pump to help drain the water out, make sure you turn it off as soon as it is empty.
  • Once all lines are drained and empty, recap the drains and close all faucets. 
  • By-pass the water heater. 
  • If you haven't already, install a water pump converter kit or disconnect the inlet side of the water pump. Connect a piece of clear tubing into the inlet side of the pump and place the other end into a one-gallon container of non-toxic RV antifreeze. 
  • Turn the water pump on and start with the closest faucet, slowly opening the hot and cold valves until the antifreeze appears. Replace the antifreeze as needed to do this. Repeat this until all faucets have antifreeze coming out of them. 
  • Flush the toilet until antifreeze appears as well. 
  • Turn the water pump off and open a faucet to release the pressure. 
  • To finish, pour a cupful of antifreeze down each drain and a couple in the toilet to flush into the holding tank. 

Next up are your tires. Yes, the tires are important! After months of thousands of pounds sitting on them, you can get flat spots on the tires. You can choose to use leveling jacks (as long as the RV is equipped) or move your RV about 1/2 a tire revolution a few times while not in use to distribute the weight. 

For your batteries, make sure to fully charge them. If it's a freezing climate area, remove them and store them somewhere warm. 

Fill the engine of your motorhome (if you have one) with fuel and a fuel stabilizer. Run the engine for a few minutes and then make sure the fluid levels are topped off. 

For your electrical system, disconnect from shore power. Remove batteries from clocks and detectors. Also, don't forget to turn off your main circuit breaker. 

Do a thorough cleaning of your RV's interior. Open the fridge and freezer to allow them to air out and dry out. Place a box of baking soda inside too. 

Make sure all vents are closed on your roof.

Don't forget about your Girard RV Awning! Extend the awning fully and clean thoroughly. Allow it to dry completely before putting it away. 


Take care of your RV and it will take care of you! Happy camping!
