Having a reliable water pump in your RV is essential for a comfortable and enjoyable camping experience. However, there may be times when you need to prime your water pump to ensure it functions properly. In this article, we will provide you with a step-by-step guide on how to prime a water pump in your RV, as well as answer some frequently asked questions about the process.

Step 1: Gather the necessary tools and materials
Before you begin priming your water pump, make sure you have all the required tools and materials. These may include a bucket, water hose, Teflon tape, pump primer, and a wrench. Having everything ready will save you time and ensure a smooth priming process.

Step 2: Locate the water pump
The water pump in your RV is usually located in a compartment or storage area. It may be behind an access panel or under a seat, so take some time to find it before proceeding.

Step 3: Turn off the water supply
Before priming the water pump, turn off the water supply to prevent any water flowing into the system during the priming process. This will allow the pump to create the necessary pressure for priming.

Step 4: Open the faucet
To relieve any pressure in the system, open a faucet or shower in your RV. This will also help in purging air from the system when priming.

Step 5: Connect a water hose to the water pump
Attach one end of a water hose to the water pump’s inlet and the other end to a bucket filled with water. Make sure the hose is securely connected to avoid any leaks during the priming process.

Step 6: Turn on the water pump
Turn on the water pump switch and listen for the sound of the pump running. You may need to wait a few seconds for the pump to build pressure and start priming.

Step 7: Monitor the water flow
As the pump primes, you should see water flowing from the faucet or shower you opened earlier. This indicates that the air in the system is being replaced by water. Let the water flow for a few minutes until all the air is expelled, and you have a constant flow of water.

Step 8: Close the faucet and check for leaks
Once you have a steady flow of water, close the faucet or shower and check for any leaks around the water pump or connections. If you notice any leaks, tighten the connections or use Teflon tape to seal them.

After priming and checking for leaks, test the water pump by using various faucets and fixtures in your RV. Ensure that water flows consistently and without any issues.

It is recommended to use clean, potable water to prime the pump. Using any other type of water may introduce contaminants into the system.

4. What is pump primer, and do I need it?
Pump primer is a chemical solution that helps create a better seal and aids in the priming process. While not always necessary, using a pump primer can make priming more efficient.
