How to Pump Antifreeze into RV

As the temperature drops and winter approaches, it’s time to start thinking about winterizing your RV. One important step in this process is pumping antifreeze into your RV’s plumbing system to protect it from freezing during the cold months. In this article, we will guide you through the step-by-step process of how to pump antifreeze into your RV.

Materials You’ll Need

  • RV antifreeze
  • A water pump converter kit or a water pump bypass kit
  • A hand pump or a water pump
  • A wrench or pliers
  • An empty bucket or container
  • A funnel

Step 1: Prepare Your RV

Before you start pumping antifreeze, make sure to drain and clean your RV’s fresh water tank, hot water heater, and any other water lines. This will help remove any residual water and prevent it from diluting the antifreeze.

Step 2: Set Up the Water Pump Converter Kit

If you have a water pump converter kit, follow the instructions provided with the kit to connect it to your RV’s water pump. This kit allows you to draw antifreeze from a bottle directly into your RV’s water system.

Step 3: Set Up the Hand Pump or Water Pump

If you don’t have a water pump converter kit, you can use a hand pump or a water pump to pump the antifreeze into your RV. Attach the pump to the intake side of your RV’s water system using the appropriate fittings.

Step 4: Prepare the Antifreeze

Before pumping the antifreeze, make sure to shake the bottle well to mix the solution. If the antifreeze is concentrated, dilute it with water according to the manufacturer’s instructions.

Step 5: Connect the Antifreeze Container

Place the empty bucket or container near the water pump or hand pump. Connect the discharge side of the water pump or hand pump to the antifreeze container using a plastic tube or hose.

Step 6: Start Pumping

Turn on the water pump or start pumping manually using the hand pump. This will create a vacuum and draw the antifreeze into your RV’s water system.

Step 7: Monitor the Antifreeze

Keep an eye on the antifreeze container and make sure it doesn’t run dry. You may need to pause pumping momentarily to refill the container with antifreeze if necessary.

Step 8: Pump Antifreeze into Each Faucet and Fixture

Open each faucet and fixture in your RV one by one, including the shower, toilet, and outdoor shower if applicable. Let the antifreeze run until you see a consistent flow of pink liquid. Repeat this step for each faucet and fixture throughout your RV.

Step 9: Flush the Toilet

Flush the toilet multiple times to ensure that antifreeze reaches the holding tank and the flush valve.


Step 10: Drain Excess Antifreeze

Once you’ve completed pumping antifreeze into your RV’s water system, drain any excess antifreeze from the faucets and fixtures. This will prevent the antifreeze from causing any taste or odor in the water system when you de-winterize your RV in the spring.

Step 11: Done!

Congratulations! You have successfully pumped antifreeze into your RV’s plumbing system. Your RV is now protected from freezing temperatures during the winter months.

Remember, the steps mentioned in this article are for a typical RV plumbing system. Make sure to consult your RV owner’s manual for any specific instructions or considerations related to your RV’s particular setup.

Stay warm and enjoy your winter adventures in your RV!

Frequently Asked Questions For How To Pump Antifreeze Into Rv

How Do You Pump Antifreeze Into An Rv?

To pump antifreeze into an RV, you’ll need a water pump converter kit and a supply of RV antifreeze. Connect the kit to the water pump, insert the hose into the antifreeze container, and turn on the water pump to push the antifreeze through the plumbing system.

What Is The Purpose Of Pumping Antifreeze Into An Rv?

The purpose of pumping antifreeze into an RV is to protect the plumbing system from freezing during winter storage. It prevents water from expanding and causing damage to pipes, valves, and fittings.

How Much Antifreeze Should I Use In My Rv?

The amount of antifreeze needed for an RV depends on the size and layout of the plumbing system. Typically, 2-3 gallons are sufficient to winterize the entire system. Refer to your RV manufacturer’s guidelines for specific recommendations.

Can I Use Regular Antifreeze For My Rv?

Regular antifreeze should not be used in an RV as it contains harmful chemicals that can be toxic when used in potable water systems. Always use RV-specific antifreeze, which is non-toxic and safe for the plumbing system.
