How To Get Air Out Of Rv Water Lines

Understanding the Importance of Proper Water Flow in Your RV

As an avid RV enthusiast, you know how crucial it is to have a well-functioning water system during your camping trips. However, sometimes you may encounter an issue where air gets trapped in the water lines, causing disruptions in the flow. This can be frustrating, but fear not! In this article, we will guide you through the steps to get air out of your RV water lines, ensuring a smooth and uninterrupted water supply.

Step 1: Close All Faucets and Drains

The first step in resolving air issues in your RV water lines is to ensure that all faucets and drains are closed. This will prevent any air from entering the system while you work on purging the existing air.

Step 2: Locate the Water Pump

Next, you need to locate the water pump in your RV. Depending on the make and model of your RV, the water pump may be in a different location. However, it is commonly found near the freshwater tank or inside a cabinet. Take the time to familiarize yourself with the layout of your RV to locate the water pump easily.

Step 3: Turn on the Water Pump

Once you have located the water pump, turn it on. This will pressurize the water system and help push out any trapped air. Allow the water pump to run for a few minutes to ensure sufficient pressure builds up.

Step 4: Open the Faucets

After the water pump has been running for a few minutes, it’s time to start purging the air from the water lines. Begin by opening the faucets one by one, starting from the closest faucet to the water pump. Let the water flow freely until you no longer hear any sputtering or see any air bubbles in the water.

Step 5: Check the Toilet

Don’t forget to check the toilet too! Flush it a couple of times to ensure that any air trapped in the toilet’s water line is also expelled. This step is often overlooked but is crucial to achieving a fully air-free water system in your RV.

Step 6: Repeat the Process

Once you have gone through the previous steps, it’s time to repeat the process for all the remaining faucets and drains in your RV. Be thorough in your approach to ensure that no air pockets remain in the water lines.

Step 7: Monitor the Water Flow

After completing the air purging process, it’s essential to monitor the water flow in your RV. Check each faucet and drain to ensure a steady and consistent flow. If you notice any irregularities or signs of air, repeat the steps mentioned above until the issue is resolved.

Step 8: Maintain Your Water System

Prevention is always better than cure. To minimize the chances of air getting trapped in your RV water lines, it’s important to maintain your water system regularly. This includes conducting routine checks, inspecting for leaks, and ensuring proper winterization if applicable.

Step 9: Seek Professional Help if Needed

If you have followed all the steps mentioned above and are still experiencing air issues in your RV water lines, it may be time to seek professional help. There could be underlying problems that require expert assistance to diagnose and fix.


Having air trapped in your RV water lines can be a nuisance, but it is a common issue that can be resolved with a few simple steps. By following the guidelines provided in this article, you can effectively purge the air from your RV’s water system, ensuring a smooth and uninterrupted water flow during your camping adventures. Remember to maintain your water system regularly to prevent future air-related problems and seek professional help if the issue persists. Happy camping!
