RV Winterization 101: Getting Antifreeze into Your Lines

Winter is right around the corner, and for RV enthusiasts, that means it’s time to start thinking about winterizing their vehicle. Winterizing an RV is an essential step to protect it from damage during the colder months. Freezing temperatures can cause costly problems like burst pipes, cracked fittings, and damaged water pumps.

One of the key components of winterizing an RV is getting antifreeze into the water lines. Antifreeze is used to protect the pipes and fittings from freezing and cracking. But if you’re new to RVing, you may be wondering how to get antifreeze into your RV lines. That’s why we’ve put together this step-by-step guide to help you winterize your RV like a pro.

With the right tools and a little bit of know-how, you can easily winterize your RV and avoid expensive repairs come springtime. So, let’s get started!

Gather Your Materials

Before you can begin the process of getting antifreeze into your RV lines, you need to gather a few essential materials. Here’s what you’ll need:

  • RV Antifreeze

The first thing you’ll need is RV antifreeze. This is a special type of antifreeze that is designed for use in RV water systems. It is non-toxic and safe for potable water systems. You’ll need enough antifreeze to fill all the water lines in your RV.

  • Water Pump Converter Kit

The next thing you’ll need is a water pump converter kit. This kit is used to pump antifreeze from a container into your RV’s water lines. It is typically made up of a hose and a fitting that connects to the water pump in your RV.

  • Bucket or Container

You’ll also need a bucket or container to hold the antifreeze as you pump it into your RV’s water lines. A 5-gallon bucket is usually sufficient.

  • Pliers

Depending on the type of water pump converter kit you have, you may need pliers to attach the hose to the fitting.

  • Rubber Gloves

It’s always a good idea to wear rubber gloves when handling antifreeze to protect your skin.

Once you have all of these materials, you’re ready to start the winterization process. It’s important to note that some RV manufacturers may have specific requirements or recommendations for the types of antifreeze or converter kits to use, so be sure to check your owner’s manual before purchasing these materials.

With the right materials and a little bit of preparation, you’ll be well on your way to winterizing your RV like a pro.

Prepare the RV

Now that you’ve gathered your materials, it’s time to prepare your RV for the winterization process. Here’s what you need to do:

1. Drain Your Water System

The first step is to drain all the water from your RV’s water system. This includes draining the fresh water tank, hot water tank, and all the water lines. You can do this by opening all the faucets and valves in your RV and letting the water run out. Be sure to also drain the water heater tank by removing the drain plug.

2. Bypass Your Water Heater

Once all the water has been drained, you’ll need to bypass your water heater. This is done to ensure that antifreeze doesn’t enter the water heater tank, which could damage the heating element. Refer to your RV’s owner’s manual for specific instructions on how to bypass your water heater.

3. Close All Valves

Next, close all the valves in your RV. This includes the hot and cold water valves at each faucet, as well as the valve on the back of the water pump.

4. Insert the Water Pump Converter Kit

Now it’s time to insert the water pump converter kit into your RV’s water system. This is typically done by removing the suction hose from the water pump and attaching the converter kit in its place. Refer to your converter kit’s instructions for specific details on how to do this.

5. Place the Bucket

Place your bucket or container of antifreeze near the water pump converter kit. You’re now ready to start pumping antifreeze into your RV’s water lines.

Connect the Water Pump Converter Kit

With your RV properly prepared, it’s time to connect the water pump converter kit and start pumping antifreeze into your water system. Here’s what you need to do:

1. Attach the Hose to the Converter Kit

The first step is to attach the hose from the water pump converter kit to the container of antifreeze. Be sure to use the appropriate fittings and clamps to secure the hose in place.

2. Turn On the Water Pump

Once the hose is securely attached, turn on the water pump. This will create suction that pulls antifreeze from the container and into your RV’s water lines.

3. Open the Faucets

With the water pump running, open each faucet in your RV one at a time. This will allow the antifreeze to flow through each water line and ensure that the entire system is protected from freezing temperatures. Be sure to also flush the toilet and run the shower to ensure that all water lines are filled with antifreeze.

4. Check for Antifreeze

As you run each faucet, check for the presence of antifreeze. The antifreeze should flow freely and steadily from each faucet, indicating that the water lines are properly filled. If you don’t see any antifreeze or the flow is weak, there may be an air bubble in the line. To fix this, close the faucet and try again.

5. Disconnect the Converter Kit

Once you’ve run antifreeze through all the water lines, turn off the water pump and disconnect the hose from the converter kit. You can then dispose of the container of antifreeze.

Fill the RV Lines with Antifreeze

Now that you’ve connected the water pump converter kit, it’s time to fill your RV’s water lines with antifreeze. Here’s what you need to do:

1. Pour Antifreeze Into the Fresh Water Tank

The first step is to pour a sufficient amount of antifreeze into the fresh water tank. This will allow the water pump to draw antifreeze into the water lines.

2. Turn On the Water Pump

With antifreeze in the fresh water tank, turn on the water pump again. This will draw antifreeze from the tank and into your RV’s water lines.

3. Open the Faucets

Once the water pump is running, open each faucet in your RV one at a time. You’ll need to do this until you see the antifreeze coming out of the faucet. Be sure to also flush the toilet and run the shower to ensure that all water lines are filled with antifreeze.

4. Check for Antifreeze

As you run each faucet, check for the presence of antifreeze. The antifreeze should flow freely and steadily from each faucet, indicating that the water lines are properly filled. If you don’t see any antifreeze or the flow is weak, there may be an air bubble in the line. To fix this, close the faucet and try again.

5. Bypass the Water Pump

Once you’ve run antifreeze through all the water lines, you’ll need to bypass the water pump. This is typically done by disconnecting the hose from the water pump converter kit and reconnecting it to the inlet side of the water pump.

6. Run the Pump Until Dry

With the water pump bypassed, turn it on again and let it run until it’s dry. This will remove any remaining antifreeze from the pump and prevent it from freezing and causing damage during the winter months.

Finish the Winterization Process

Now that you’ve filled your RV’s water lines with antifreeze, you’re almost done with the winterization process. Here’s what you need to do to complete the process:

1. Drain the Water Heater

Start by draining the water heater. This is important because water left inside the water heater can freeze and cause damage. To do this, turn off the water heater and let it cool down. Then, locate the drain valve and attach a hose to it. Open the valve and let the water drain out.

2. Drain the Water System

After draining the water heater, you’ll need to drain the entire water system. This includes the fresh water tank, the gray water tank, and the black water tank. To do this, open all the drain valves and let the water flow out. You can also use an air compressor to blow out any remaining water from the water lines.

3. Remove Water Filters

Next, remove any water filters in your RV. Water filters can trap water and cause damage if they freeze, so it’s important to remove them before winterizing.

4. Close all Faucets and Valves

Once you’ve drained the water system, close all the faucets and valves in your RV. This will prevent any water from entering the system during the winter months.

5. Add Moisture Absorbers

Finally, add moisture absorbers throughout your RV. Moisture can build up during the winter months and cause mold and mildew to grow. By adding moisture absorbers, you’ll help prevent this from happening.

By completing these final steps in the winterization process, you’ll ensure that your RV is fully prepared for the winter months. This will also help prevent damage and keep your RV in good condition for years to come.
