Traveling in an RV offers the freedom to explore the great outdoors while enjoying the comforts of home. However, a malfunctioning water pump can quickly disrupt your plans. If you find that your RV water pump isn’t pumping, it’s important to understand the common causes and how to address them. 

Common Reasons Your RV Water Pump Isn’t Pumping

Power Supply Issues

Check the Fuse: The first thing to investigate is the power supply. A blown fuse can prevent the pump from functioning. Locate the fuse associated with the water pump and inspect it. If it’s blown, replace it with a new one of the same rating.

Inspect Electrical Connections: Ensure that the pump is properly connected to the power source. Look for any loose or damaged wires that may be affecting performance.

Empty Water Tank

Verify Water Levels: One of the simplest causes of a non-functioning pump is an empty water tank. Make sure your fresh water tank is filled. If it’s low, fill it up and try activating the pump again.

Air Leaks in the System

Inspect Hoses and Fittings: Air leaks can significantly impact the pump's ability to create suction. Check all hoses and fittings for cracks or loose connections that might allow air to enter the system.

Tighten Connections: Ensure all connections are secure to prevent air from entering and disrupting water flow.

Blockages or Clogs

Examine the Inlet Screen: Many pumps have an inlet screen designed to catch debris. If this screen is clogged, it can restrict water flow. Remove and clean it thoroughly.

Check for Kinks: Inspect the hose for any kinks or blockages that might be impeding water flow. Straighten out any bends in the hose to improve performance.

Pump Priming Issues

Manual Priming: Some RV pumps require manual priming. If your pump has lost its prime due to air in the system, you may need to fill the pump housing with water to get it running again.

Pump Malfunction

Listen for Unusual Noises: If the pump makes grinding or rattling noises, it may be malfunctioning. Turn it off to prevent further damage.

Inspect for Damage: Look for visible signs of wear or damage. If the pump is compromised, it may need to be replaced.

Faulty Switch or Wiring

Test the Switch: If the pump doesn’t activate, the switch itself may be faulty. Ensure that it feels secure and responds properly when activated.

Check Wiring Connections: Inspect the wiring for any frayed or damaged sections that could be affecting performance.

Consult the Owner’s Manual

Follow Manufacturer Guidelines: If troubleshooting doesn’t resolve the issue, refer to your RV’s owner’s manual for specific troubleshooting tips related to your model’s water pump.
