De-winterizing your RV


It may be taking its good sweet time, but spring and all of its showers are certainly here. Although it might not be camping season for most just yet, it is the perfect time of year to prepare your RV for camping season.

Warmer weather means that RV owners are now free to de-winterize their campers and let some fresh air in.

De winterizing your camper each spring is the same idea as spring cleaning, you want to make sure everything is fresh and clean for the new season coming up. Ready to go when you need it. The last thing you want to do is rush to prepare your RV for summer and forget something you need before your first trip.

For first-time campers or those that aren’t comfortable de-winterizing their RV themselves Service centers, including Stones can complete this task for you, making it hassle-free.


Flush and sanitize your water system

At some point in your travels over the summer, you’re going to need to use the water in your RV, that’s what it’s there for of course. An important step to making sure your RV is ready for the summer is flushing out the tank to get rid of the antifreeze that prevents the pipes from freezing over the winter.

  • Begin by closing all your taps and then putting your heater back in the summer position.
  • Then fill the tanks with water or hook up your city water connection. 
  • Taps can now be opened, allow them to run until the water runs clear so you know all of the antifreeze is out of the system.


Sanitizing your water system will allow you to get anything else that may have ended up in the water tank or any bit of antifreeze that may have been left behind after the flush.

  • First, begin by closing all of the taps and putting a drain plug in.
  • Next, take a quarter-cup of household bleach for every 15 gallons of water that goes in your freshwater holding tank. Mix the bleach with water into a 1-gallon container. Now, pour the mixture into your tank. 
  • You can also use water sanitizer products specifically made for RVs for this step as well.
  • Turn on the water pump and open all faucets.
  • Run the water until you can smell the bleach and then close the faucets.
  • Let the solution sit for up to twelve hours in the water tank and water lines.
  • Drain all of the water from the system.
  • Refill the freshwater tank with potable water.
  • Flush the system by turning on the water pump and opening all faucets.
  • Allow the water to run until it no longer smells like bleach.

Charge up and reinstall your RV battery

With a fresh charge in your battery for the RV, you will be all set to run a few different systems in your unit as well as helping with the jack to raise and lower your RV.

  • Check the voltage of your battery with a voltmeter
  • Charge up your battery with a battery charger or power supply.
  • Check the water levels of the battery and top them up if they are too low
  • Ensure your battery connection is secure

If you’re unsure about charging or working with your battery too much, a service center such as Stone’s can always help out with this so a professional can take it on rather than risking a possible shock.


Check and inspect the exterior

Depending on how you have stored your RV for the winter the exterior can take a bit of wear and tear from being left in the elements. The best way to make sure that nothing has seriously damaged any parts of the RV is to complete an exterior inspection to make sure that the caulking is still all intact and not hardened or cracking. This can be done by taking a slow walk around the unit and checking out each part individually.


Replace your propane tanks

There would be nothing worse than getting out to your camping site and realizing on a chilly night you have no heat, or you have no propane left to grill your supper or breakfast. Before you hit the road or spend your first night in your RV it is always a good idea to replace your propane tank with a full one to make sure you are ready to go.


Check Your Tires

No one is a fan of replacing a flat tire on the side of the road and you certainly don’t want to be dealing with a leaky or flat tire on your RV on the way to your destination. Check your tire pressure before getting ready to set out for the summer and fill your tires up with air if you find they are low. Temperature changes can affect the pressure of your tires so It is always a good idea to make sure they are adjusted for the summer weather.
