When the weather begins to turn cool, the RVing season winds down for most of us. During the fall, it is wise to prepare your RV for the harsh winter months. Taking the time to winterize and protect your RV or camper from the elements is a critical part of protecting your investment. 

Everyone has heard horror stories of the damage that can be done by freezing pipes in both RVs and campers. Taking the proper steps to drain your lines and protect your RV from damage will be well worth it. This process is known as winterization.

Why You Need to Winterize Your RV

If you do not protect your RV and its plumbing system, water left inside your pipes or tanks can freeze when temperatures dip below the freezing point. When water freezes, it expands and can cause significant damage to your pipes, tanks, and fittings. 

Winterizing your camper is highly recommended to protect your precious investment. If you live in an area where the temperature dips below 32 degrees Fahrenheit at any point during the winter, it is best to winterize your RV. 

If you live in areas where freezing temperatures are rare or unlikely, you may not need to winterize your RV. However, if there is any chance of cold temperatures, it is wise to take action in advance. It is also a good idea to thoroughly inspect your RV as you winterize to make sure it is in good condition before you store it until next season.

How Cold can it Get Before I Have to Winterize My RV or Camper?

If the temperature gets below 32 degrees Fahrenheit at any time, you run the risk of having water freeze in your pipes, tanks, or water heater. If this happens, you could potentially have severe damage to your RV. 

While some folks think that it is okay to wait to winterize your RV until you have a full 24 hours with temperatures below 32 degrees Fahrenheit, the truth is you could have damage from even a few hours with temperatures below freezing. 

To be on the safe side, it is best to winterize your camper before temperatures of 32 degrees Fahrenheit or below are forecast for your area.

What Happens if You Don’t Winterize Your RV or Camper?

If you choose not to winterize your RV and temperatures fall below 32 degrees Fahrenheit, you run the risk of severe damage to your RV. 

When temperatures fall below the freezing point of 32 degrees Fahrenheit, water freezes. When water freezes, it expands, and this expansion can cause significant damage to your pipes, tanks, and fittings. Pipes and fittings can break, tanks can crack, and your entire plumbing system could be damaged. 

Many people think that they can simply drain all of the water out of their lines instead of doing a full winterizing process on their RVs. However, there are many places inside your RV where water can pool and sit, even if you drain the lines. If this water freezes, you will have a problem. 

The best way to avoid these issues is to winterize your RV. If you live in an area where the temperature dips below 32 degrees Fahrenheit at any point during the winter, you seriously need to consider winterizing your rig. If you do not want to do it yourself, you can always have an RV service center take care of this process for you. The cost of winterizing, even when done by professionals, is much less than the cost of repairing damaged pipes and tanks. 

Do I Need to Winterize My RV or Camper if it is Plugged In All Winter?

If your camper is connected to power all winter, you may wonder if it is necessary to winterize at all. Remember that the main reason to winterize is to protect your pipes and tanks from damage due to bursting pipes. Pipes can burst any time temperatures dip below freezing, whether your camper is plugged in or not. 

Having your camper plugged in does not offer protection from low temperatures. While you could run your heater to keep temperatures warm in your camper, this comes at a cost. Overall it is best to winterize your RV even if you plan to keep it plugged in throughout the winter months.

How Much Does It Cost to Winterize an RV or Camper?

If you do not have the time or desire to winterize your RV yourself, you can have someone do this for you. Most RV dealers and service centers offer winterizing services, so it should not be hard to find a place to have this service done. 

The price for winterizing your RV will vary based on a few factors. Your location, the service center you choose, and the size and style of your RV will impact the cost of winterization. The cost of winterizing a Class A motorhome ranges from $150 to $200. For a Class B or C camper, the price will be a little bit less. Expect to pay anywhere from $100-$150 for this service. 

One important thing to keep in mind if you plan to have someone else winterize your RV is that you will need to schedule this service months in advance. All RVers winterize their rigs around the same time, which means that demand is high for this service during the late fall and early winter months.

Fall and early winter are also busy times for RV service centers in general, as many people prefer to get maintenance done on their RVs during the colder months when they are not traveling. For these reasons, you will need to schedule the service ahead of time and be sure not to wait until the last minute. 

How Do I Winterize an RV or Camper?

Winterizing your RV for the first time is not as difficult as you think. Before you get started, be sure to check out your RV owner’s manual for any specific steps or procedures needed for your rig. 

Next, you will need to assemble the materials needed to winterize your RV. 

1. Remove any Inline Water Filters

The chemicals that you will use to winterize your RV can damage water filters. For this reason, you will need to be sure to remove them before beginning winterization. 

If you have an inline filter for your faucet, check for the bypass hose you can use when the filter is removed. 

While you have your filters removed, this is a great time to check them out to see if they need to be replaced with new ones. 

2. Drain Your Tanks

All of your tanks- fresh, black, and gray- will need to be drained before adding antifreeze to your RV. Start with the fresh water tank and make sure it is empty. Next, drain and flush your gray and black water tanks. Make sure that you are draining them at an approved RV dumping station. After draining your tanks, clean them with an RV flushing wand. You may not need to use an RV wand if your camper has a built-in flushing system. 

3. Drain Your Water Heater and Water Lines

Once you have drained your tanks, it is time to tackle the water heater and water lines. It is important to note that you will need to turn off your water heater and let it cool down and depressurize before attempting to drain it. Do not drain the water heater tank before doing this! 

Once you have allowed time for the water heater to cool and depressurize, remove the drain plug, and open the pressure relief valve. 

Next, open all of your faucets in the RV, both hot and cold, to allow them to drain. You will need to drain your outside shower line if you have one as well. Don’t forget your toilet valve! You can use your water pump to do this. Just be sure to shut it off as soon as everything is drained. When you are finished, recap all drains and close the faucets. 

4. Bypass Your Water Heater

Before you add antifreeze to your camper, you will need to bypass the water heater. Bypassing the water heater prevents antifreeze from getting into your water heater. Some RVs come with a bypass. If your RV does not have a water heater bypass, you will need to install a bypass kit. You can also have this done at an RV service center. 

5. Add Antifreeze to Your RV

To get antifreeze into your RV system, you will need to do one of two things. You can install a water pump converter kit or disconnect the inlet side of your water pump and connect clear tubing. You can then put the other end of the tube into your container antifreeze. 

The next step is to turn on your water pump and pressurize the system. The water pump will take antifreeze throughout your RV water system. After you turn on the pump, walk through your camper, and turn on the faucets. Start with the closest faucet, and slowly open the hot and cold valves until you see antifreeze. You may need to replace the antifreeze container as you work your way through your rig. Don’t forget to do your outdoor shower and flush the toilet as well. You will need to flush until the antifreeze appears.

Finally, pour a cup of antifreeze down your drains and the toilet. Flush the antifreeze into the holding tank. Make sure all faucets are closed, and you are done! 

Conclusion

Whether you choose to winterize yourself or have it done at a service center, winterizing your RV is a smart choice to make. Winterizing protects your investment and gives you peace of mind. No matter how low the temperatures drop, your RV is safe from water damage with proper winterization. Now you can kick back, relax, and start planning your spring camping adventures!
