A Guide on How to Prime Your Camper Water Pump

How to Prime Your Camper Water Pump

A well-functioning water pump is essential for a comfortable camping experience in your camper. If you've noticed a lack of water pressure or no water flow at all, it's possible that your camper water pump needs priming. In this informative guide, we'll walk you through the steps on how to prime your camper water pump, ensuring a steady and reliable water supply during your outdoor adventures.

Step 1: Locate the Water Pump

Before beginning the priming process, locate your camper's water pump. It's typically situated near the fresh water tank, and you may need to remove an access panel to reach it.

Step 2: Turn Off the Pump and Water Source

Ensure the water pump and any external water sources, such as city water or a freshwater tank, are turned off. This prevents water from flowing into the system while you're priming the pump.

Step 3: Open Faucets

Open all faucets inside your camper, including both hot and cold taps. This helps release any air trapped in the water lines and ensures an efficient priming process.

Step 4: Access the Water Pump

Remove the pump's cover or housing to access the pump itself. Some models may have a priming lever or button, while others may require manual priming.

Step 5: Manual Priming (If Necessary)

If your water pump doesn't have an automatic priming feature, manually add water to the pump. Pour water directly into the pump until it's full, and replace the pump cover securely.

Step 6: Activate the Pump

Turn on the water pump and let it run. Keep a close eye on the faucets inside your camper. You'll likely hear the pump working to pressurize the system, and water should start flowing steadily from each faucet.

Step 7: Check for Air Bubbles

Continue running water through the faucets until you no longer see air bubbles. Air in the lines can cause sputtering and reduce water pressure, so it's essential to ensure a complete purge of air from the system.

Step 8: Close Faucets

Once you've confirmed a steady flow of water without air bubbles, close all faucets inside your camper. This completes the priming process, and your water pump should now operate efficiently.

Step 9: Monitor Pressure

Monitor water pressure and ensure there are no unusual sounds or vibrations coming from the pump. If you notice any issues, double-check the priming process and inspect the system for leaks.


Priming your camper water pump is a straightforward process that ensures a reliable water supply during your camping adventures. By following these steps, you can confidently address any issues with your water pump, allowing you to enjoy the convenience of a consistent water flow in your camper.
