1. Turn Off the Water Pump and Disconnect from the City Water Supply

For safety, turn the water pump switch off and disconnect the pump from the city water supply.

2. Remove the Fuse

Remove the fuse that powers your water pump. It is a safety precaution.

3. Open the Faucet

Open the faucets on the RV to drain all the water and release pressure in the RV plumbing system. Start the replacement process when the water stops flowing from the faucets.

4. Detach the Water Pump from Latching Controller

Not all RVs have a latching controller. A latching controller enables your RV to have multiple on/off switches for the water pump. It is usually located near the water pump. To disconnect the pump from latching controller, cut off the ground wire first. The ground wire is the black wire. Next, cut off the positive lead from the latch controller.

The positive lead is the red wire. The positive lead, or the red wire, is attached to the yellow wire. Remove the yellow wire from the latching connector. Remember these steps or take a photo so that you can remember when you mount the new pump.

5. Disconnect the Inlet and Outlet Lines from the Pump

Place the pan or bucket underneath before you unscrew it, as some water will leak out. Use your hands when unscrewing to avoid damaging the plastic fittings. You can gently use the pliers if it’s too tight.

6. Remove the Inlet Filter

Remove and clean the inlet filter, as you might need to install it on the new replacement RV water pump. If the filter is old, worn out, or too clogged, consider buying a new one.

7. Place the New RV Water Pump in Position and Install the Filter

Mount the new pump in place and reinstall the inlet filter. Take note of the arrows on the pump and filter indicating the direction of the water flow. Ensure the arrows are facing in the same direction. Use the crescent wrench to screw the new pump fittings into the filter.

8. Place the New Water Pump into the Rightful Position

Mount the new pump into the same location as the old pump, on the RV floor or wall. Attach the screws and ensure the pump is secure in its position.

9. Attach the Inlet and Outlet Water Lines to New Water Pump

Connect the inlet and outlet hoses to the new water pump. You can use your hand to fasten the hoses connected to the threads of the fittings.

10. Connect the Wires to the Latch Controller

Connect the black wire or the ground wire by crimping on a spade connector. You can use the photos you took earlier for reference.

Take the yellow wire you had earlier snipped off and the end of the red wire and twist them together while crimping on a spade connector.

Gently pull the spade connectors to ensure they are tightly crimped to avoid electrical faults in the future due to loose connections. Lastly, place the spade connectors in their respective positions on the latching controller. If your RV does not use the latching controller, you can use the butt connectors.

11. Reconnect Back Power and Water

Once you are done replacing an RV water pump, replace the fuse to power the pump. Reattach the water hoses to the city water and fill the RV’s freshwater tank.

Open the faucets and allow water to flow for some time to ensure no sputtering. Ensure all the trapped air is pushed out. Also, keep the water pump running for a while to allow the plumbing lines to pressurize. You can monitor the new RV water pump replacement for leaks.

You can tighten the fittings if there are any leaks and turn off the pump if there is none. You have completed replacing RV water pump.

Tips for Buying the Right Replacement RV Water Pump

When choosing an RV water pump to replace the old one, consider three main factors: performance, safety, and convenience. Here are tips for buying an RV water replacement.

1. RV Pump Water Flow Rates

The flow rate is the amount or volume of water the pump can process and is quantified in gallons per minute (GPM) or liters per minute (LPM). It’s the maximum water volume the pump is capable of pumping to your faucets, toilet, or shower. Ensure the pump you choose has a pumping capacity of 3.0 and 5.5 GPM.

2. Water Pressure

Another key consideration is the pressure the pump is capable of pushing water through, measured in pounds per square inch, or (PSI). Ensure the water pressure of the pump matches the RV’s plumbing system.

3. The Size of the Pump

Another thing to consider is the size of the pump and the size of the RV. While an RV water pump should be compact to fit in the limited space of the RV, it should have enough capacity to supply water to your RV. A bigger RV will require a bigger capacity water pump.

4. Noise Level

Various RV water pumps have varying levels of noise. When choosing the RV water pump, check the noise level in dB. Choose what you are comfortable with, and allow you to rest or sleep with minimal disturbance.

5. Thermal Protection

Your safety in the RV is paramount. Most RVs use the 12V water pump with electric motors that generate heat. Sometimes, overheating of the motor can cause a fire in your RV. Buy an RV water pump with a thermal protection feature and other necessary safety features. Thermal protection will automatically switch off the water pump in case it starts to overheat.
