De-Winterize Your RV in a Flash


With warmer weather here to stay you’re probably eager to get out and make the most of it. Before you head out, though, you’ve got to de-winterize your RV. This process not only allows you to use your plumbing system, it also gives you the opportunity to give the RV a once over and ensure your RV’s body is in the proper shape to use over the season.

Before you start de-winterizing your RV, you’ll want to ensure you have the proper supplies. You’ll need a hose, access to fresh water, bleach and cleaning supplies.

Start by reconnecting your battery and draining all anti-freeze from your RV. Fill your fresh water tank with water. Run your faucets to flush the anti-freeze out. Remember to flush your toilet and be sure to turn on any outside plumbing fixtures too.

Once the anti-freeze is drained you’ll want to refill your fresh water tank with 1/4 bleach for every 15 gallons of water it holds. Mix in fresh water and run this bleach mixture throughout all water pipes by turning on the faucets and letting the water sit in the pipes for twelve hours.

Once your pipes have been disinfected you’ll want to run fresh water through until you can no longer smell bleach.

After your plumbing system has been de-winterized, you’ll want to give your RV a thorough cleaning inside and out. Take this opportunity to inspect the interior and exterior for any openings where critters could enter and damage that needs to be fixed before you hit the road.
