The ultimate guide to rv water pumps: types, functions, and maintenance

An RV water pump is the unsung hero of your recreational vehicle’s water system. It’s the workhorse that ensures a steady flow of water to all the faucets, sinks, and toilets in your RV. Without it, you’d be stranded in a waterless wasteland!

How Does an RV Water Pump Work?

An RV water pump operates on the principle of a diaphragm pump. When you turn on a faucet or flush a toilet, an electrical signal is sent to the pump. This signal activates a motor, which drives a diaphragm back and forth.

As the diaphragm moves, it creates a vacuum that draws water into the pump chamber. The water is then pushed out of the pump and into the RV’s plumbing system.

Types of RV Water Pumps

There are two main types of RV water pumps:

• Submersible pumps: These pumps are installed inside the RV’s water tank. They are more compact and quieter than external pumps, but they can be more difficult to access for maintenance.
• External pumps: These pumps are mounted outside the RV, typically under the chassis. They are easier to access for maintenance, but they can be noisier than submersible pumps.

Choosing the Right RV Water Pump

When choosing an RV water pump, there are a few factors to consider:

• Flow rate: This is the amount of water the pump can deliver per minute. A higher flow rate will provide a stronger stream of water.
• Pressure: This is the amount of force the pump can generate. A higher pressure will allow you to use multiple fixtures at the same time.
• Voltage: Most RV water pumps operate on 12 volts DC. However, some models are available that operate on 110 volts AC.
• Size: The size of the pump will determine where it can be installed. Make sure to measure the available space before purchasing a pump.

Installing an RV Water Pump

Installing an RV water pump is a relatively simple process. However, it’s important to follow the manufacturer’s instructions carefully to ensure a proper installation.

Here are the general steps involved in installing an RV water pump:

1. Disconnect the RV’s electrical system.
2. Locate a suitable location for the pump.
3. Mount the pump according to the manufacturer’s instructions.
4. Connect the pump to the RV’s plumbing system.
5. Reconnect the RV’s electrical system.
6. Test the pump to make sure it’s working properly.

Troubleshooting RV Water Pump Problems

If you’re having problems with your RV water pump, there are a few things you can check:

• Check the power supply: Make sure the pump is connected to a power source and that the power is turned on.
• Check the fuses: If the pump is not getting power, check the fuses to see if they have blown.
• Check the water supply: Make sure there is water in the RV’s water tank.
• Check the pump for leaks: If the pump is leaking, it will need to be repaired or replaced.
• Check the pump for air: If the pump is sucking air, it will not be able to pump water properly.

Wrap-Up: The Importance of a Reliable RV Water Pump

A reliable RV water pump is essential for a comfortable and enjoyable camping experience. By understanding how an RV water pump works, you can choose the right pump for your needs and install it properly. With a little care and maintenance, your RV water pump will provide you with years of trouble-free service.
