As the days get shorter and the weather gets colder, it’s time to get your RV ready for winter. Winterizing your RV isn’t just another chore – it’s an important step to keep your RV safe from damage during the cold months. One of the most important parts of RV winterizing is protecting your water lines and tanks. 

If water is left in the system, it can freeze, expand, and cause big problems when you’re ready to hit the road again in the spring. Today, we’ll walk you through the basics of RV winterization to help keep your water system in good shape.

 

Why Winterizing Your RV Is Important

You might be wondering why you need to bother with winterizing your RV. The answer is simple: freezing temperatures can cause a lot of damage if your RV isn’t ready. When water freezes, it expands. If there’s water in your RV’s pipes or tanks during the winter, that expansion can cause pipes to burst or tanks to crack. Repairs like this can be expensive and take a lot of time. A little effort now can save you money and frustration later.

Besides preventing damage, winterizing also keeps your RV clean and ready for use when spring comes. Nobody wants to find mold, mildew, or bad smells in their RV after months in storage. Proper winterization helps prevent those issues too.

 

Draining Your RV’s Water System

The first step in winterizing your RV is to drain all the water from the system. This means emptying the fresh water tank, the gray water tank, and the black water tank. Start by opening all the faucets (both hot and cold) and let any remaining water drain out. Make sure to flush the toilet too, so you get all the water out of the toilet lines.

You’ll also need to drain the water heater. Before you do this, make sure the water heater is turned off and has cooled down. Hot water can be dangerous to work with, so take your time here. Once it’s cool, open the drain plug or valve on the water heater and let the water flow out.

Lastly, don’t forget to drain the low-point drains. These are usually the lowest spots in your RV’s water system and can hold leftover water that needs to be drained before you add antifreeze.

 

Adding RV Antifreeze to the System

Once all the water is drained, it’s time to add RV antifreeze. RV antifreeze is made to be non-toxic and safe for your plumbing system. Do not use regular car antifreeze – it can be harmful to both you and your RV.

To get started, you’ll need a water pump bypass kit if your RV doesn’t already have one. This lets you pump antifreeze through your system without filling up the water heater, which saves time and money. Once the bypass kit is installed, use the RV’s water pump to draw antifreeze into the system.

Turn on the water pump and open each faucet one at a time, starting with the one farthest from the pump. Let the antifreeze run through until you see a steady stream of pink liquid. Don’t forget to run antifreeze through the shower, toilet, and any outdoor shower or rinse stations your RV has. Finally, pour some antifreeze down each drain – this will help protect the P-traps from freezing.

 

Protecting Your RV Water Tanks

The fresh water, gray water, and black water tanks also need attention when winterizing. After draining them, make sure they are as clean as possible before putting your RV into storage. You can use a tank cleaning wand or a rinse system to get rid of any debris or buildup inside the tanks.

Once the tanks are clean and drained, it’s a good idea to add a little RV antifreeze to each one, especially the black and gray water tanks. This will help protect any leftover water in the tanks from freezing and cracking. You don’t need to fill the tanks with antifreeze, just enough to cover the bottom will do the job.

 

Tips for Avoiding Common Winterizing Mistakes

Winterizing your RV might seem simple, but there are some common mistakes that people make. Here are some tips to avoid them:

  1. Don’t Forget the Water Heater: Many people forget to drain the water heater before adding antifreeze, which can cause damage. Always make sure the water heater is empty and bypassed before you start pumping antifreeze.
  2. Use the Right Antifreeze: Make sure you’re using RV-specific antifreeze, not car antifreeze. RV antifreeze is non-toxic and safe for your water system.
  3. Check for Low Points: Remember to drain the low-point drains in your RV. These are the lowest parts of the water system and can hold water that will freeze if not properly drained.
  4. Don’t Forget the Outdoor Shower: If your RV has an outdoor shower, make sure you run antifreeze through it too. It’s easy to forget, but frozen lines here can still cause problems.

 

RV Air Conditioner Maintenance Before Winter

While winterizing is mostly about protecting your water lines and tanks, it’s also a good time to take care of your RV’s air conditioner. Proper RV air conditioner maintenance will help make sure it’s ready to go when you need it next summer. Start by cleaning or replacing the air filter. If possible, cover the AC unit to protect it from dust and debris during the winter.

Also, check the seals around the air conditioner. Over time, these seals can crack or wear out, allowing moisture to get inside. If you notice any problems, fix them before storing your RV for the winter. This small step can help extend the life of your air conditioner and keep it in good shape.

 

Final Steps Before Storing Your RV

Once you’ve taken care of the water system and finished your RV air conditioner maintenance, there are a few more steps before putting your RV into storage. Make sure all windows and vents are closed tightly to keep out moisture and pests. Use moisture absorbers inside the RV to help prevent mold and mildew during the winter.

It’s also a good idea to take the battery out of your RV and store it in a cool, dry place. Make sure the battery is fully charged before storing it, and check it a few times during the winter. A battery maintainer can help keep it charged and ready for use when spring arrives.

 

Protect Your RV with Proper Winterizing

Winterizing your RV is all about protecting your investment. By draining the water system, adding RV antifreeze, cleaning out your tanks, and taking care of RV air conditioner maintenance, you’re making sure your RV will be ready to go when warmer weather returns.
