How to Turn on Water Pump in RV

Are you new to RV camping and have no idea how to turn on the water pump in your vehicle? Do not worry, you are not alone.

When traveling in your RV, having access to running water is essential for daily activities like washing dishes, taking showers, or using the restroom. The water pump in your RV plays a critical role in bringing water from the onboard storage tank to your faucets and appliances. If you’re new to RVing or have just upgraded your rig, figuring out how to turn on the water pump might seem daunting.

How to Turn on Water Pump in RV

This guide on how to turn on water pump in RV will walk you through the steps to ensure your water pump is correctly activated, allowing you to enjoy a smooth and comfortable adventure on the road.

What Are the Causes of Water Pump Failure?

Water pump failure can be caused by a variety of factors, including:

  • Electrical Issues: If the wiring to the water pump is damaged or faulty, it can prevent the pump from receiving power and functioning properly.
  • Airlock: Sometimes, air can get trapped in the water pump lines, preventing water flow. This can happen if your RV has been sitting unused for a long time or if there was an interruption in the water supply.
  • Clogged Filters: A build-up of debris and sediment can clog the filters on your water pump, causing it to work harder and eventually fail.
  • Age and Wear: Like any mechanical component, a water pump will wear out over time. If your RV is older, it may be time to replace the water pump.
  • Leaks: A leak in the water pump or its connections can cause a decrease in water pressure and eventually lead to failure.
  • Improper Installation: If the water pump is not installed correctly, it may not function properly. It’s essential to have a professional install or check the installation of your RV’s water pump.

What Will You Need?

To replace your RV’s water pump, you will need:

  • New water pump
  • Wrench set
  • Screwdriver
  • Pliers
  • Teflon tape

Once you have these materials, you will be ready to replace your RV’s water pump and ensure proper functionality of your water system.

8 Easy Steps on How to Turn on Water Pump in RV

Step 1: Locate the Water Pump Switch 

The first step in activating your RV’s water pump is finding the water pump switch. Generally, this switch is inside your RV, often near the kitchen area, bathroom, or central control panel. Look for a labeled switch or button that says “Water Pump” or has an icon resembling a water drop or pump.

If your RV is more significant or has multiple control panels, you may need to consult your RV’s user manual to pinpoint the exact location. Some RVs also feature a more modern digital control system where the switch might be accessible through a touchscreen interface.

Take a moment to familiarize yourself with its location, as you might need to turn it off after use to save battery power and prevent unnecessary wear on the pump.

Step 2: Turn On the Water Pump Switch 

Once you have located the water pump switch, simply flip or press the switch to activate it. You may hear the pump start to hum or engage as it pressurizes the water system in your RV.

This will allow water to flow to your faucets, shower, and other appliances that rely on the water system. If your RV has a digital control system, follow the prompts on the touchscreen to activate the pump. Ensure that the water pump indicator light (if applicable) turns on, confirming it’s functioning correctly.

Step 3: Monitor the Water System

Once the water pump is activated, check your system to ensure everything functions as expected. Turn on a faucet or shower to test for proper water flow and pressure. Listen for any unusual noises from the pump, such as excessive cycling or loud vibrations, which could indicate a problem.

Additionally, inspect for any leaks around water connections or appliances. Turn off the pump and troubleshoot the system before proceeding if you notice any issues. Regular monitoring helps maintain the efficiency and longevity of your RV’s water system.

Step 4: Check Electrical System

As with the water system, checking and maintaining your RV’s electrical system is essential. Start by checking all outlets and appliances for proper functionality. Make sure all wires and connections are secure and not damaged. Testing the battery voltage levels using a multimeter is also a good idea. You may need to charge or replace the batteries if they are low.

Next, inspect the power cord and plug for any signs of damage or wear. Replace if necessary. Check the circuit breakers and fuses in your RV’s electrical panel to ensure they function properly. If you notice any issues or have concerns, consult a professional electrician.

Step 5: Test All Appliances

After verifying the electrical system’s health, test all the appliances in your RV. Start by turning on each device individually to ensure it powers up correctly and functions as expected. Pay attention to common appliances such as the refrigerator, microwave, air conditioner, and water heater.

Listen for unusual noises, check for irregular performance, and verify that each appliance operates within its normal parameters. If you encounter any issues, consult the appliance manufacturer’s manual or seek assistance from a qualified technician to address the problem. Properly functioning appliances are essential for a safe and enjoyable RV experience.

Step 6: Inspect the RV’s Plumbing System

Evaluate the RV’s plumbing system to ensure it is working well. Check for leaks in the pipes, faucets, or connections, and ensure the water pump operates efficiently.

Test the fresh water and wastewater systems, including the gray and black water tanks, for proper functionality. Run water through all faucets to confirm consistent flow and monitor for any unusual odors or discoloration. Regular plumbing system maintenance prevents water damage and ensures a comfortable and worry-free trip.

Step 7: Gas and Propane System

The gas and propane system is an essential component of your RV that powers appliances such as the stove, refrigerator, and water heater. Before heading out on your trip, it is crucial to check the gas and propane system for any leaks or malfunctions.

Start by inspecting the exterior connections for any damage or loose fittings. Ensure all valves are closed before connecting your RV to a fuel source. Once connected, turn on the main valve and check for any signs of leakage using a soapy water solution. Bubbles will appear if there is a leak, in which case you should tighten the connection or replace the damaged part.

Step 8: Keep Emergency Supplies Handy

No matter how well-prepared you are, emergencies can still happen on the road. It is essential to always have a well-stocked emergency kit in your RV. This should include first-aid supplies, a fire extinguisher, flashlights, batteries, and non-perishable food items.

Additionally, it may be helpful to have tools and spare parts for any potential mechanical issues that may arise. Consider adding duct tape, tire repair kits, and extra fuses to your emergency kit.

By following these tips, you can ensure a safe and enjoyable RV road trip. Remember always to plan ahead, be aware of your surroundings, and have the necessary supplies and knowledge to handle any situation that may arise.

5 Things You Should Avoid

  1. Skipping the Manual: Always read the RV’s manual thoroughly before turning on the water pump. Each RV model may have different systems or steps to activate the pump safely. Ignoring the manual can result in errors or even damage.
  2. Forgetting to Prime the System: If your RV’s water system has been unused for a while, forgetting to prime it before turning on the pump can cause airlocks and disrupt water flow, unnecessarily stressing the pump.
  3. Running the Water Pump Without Water in the Tank: Never turn on the water pump if the freshwater tank is empty. This can lead to the pump running dry, which may overheat and damage its components.
  4. Leaving Valves in Incorrect Positions: Check that all necessary valves, such as those leading to the water lines, are in the correct position before switching on the water pump. Incorrect valve positions can lead to leaks or water pressure issues.
  5. Ignoring Unusual Noises or Leaks: If you notice strange noises like excessive vibrations or observe leaks when the water pump is running, do not ignore them. These could be signs of underlying issues that need immediate attention to prevent further damage.
