RV Water Pump: What You Need to Know and How to Replace It

Are you new to RVing and wondering what an RV water pump is? Or are you a seasoned RVer looking to replace your current water pump? Either way, understanding your RV water system and how the water pump works is crucial for a successful and comfortable trip.

The RV water pump is responsible for providing water flow and pressure throughout your RV’s plumbing system, whether you’re using water from the fresh water tank or the city water connection. It pumps water through the water lines to your faucets, shower, and toilet. Without a properly functioning water pump, you won’t have any water pressure, and your RV’s plumbing system won’t work correctly.

If you’re experiencing low water pressure or no water flow, it may be time to replace your RV water pump. Replacing the water pump is a relatively easy task that you can do yourself with a few basic tools and some knowledge of your RV’s plumbing system. In this article, we’ll cover what you need to know about RV water pumps, how they work, and how to replace them.

What is an RV Water Pump?

If you own an RV, then you know that having a reliable source of water is essential. That’s where the RV water pump comes in. This pump is responsible for drawing water from your fresh water tank and distributing it throughout your RV’s plumbing system.

A typical RV water pump is similar to other mechanical water pumps used in vehicles and machinery. It uses electricity to pump water from a localized source through the piping to your sink, bathroom, shower, and other water outlets. The pump works by creating pressure, which forces the water to move through the pipes.

The water flow and pressure are measured in gallons per minute (GPM) and pounds per square inch (PSI), respectively. It’s important to note that the amount of water flow and pressure can vary depending on the type of water pump you have installed in your RV.

One popular brand of RV water pump is the AquaJet, which is known for its high-performance and reliability. Another important component of the RV water pump is the pressure switch, which turns the pump on and off as needed to maintain the desired water pressure.

The RV water pump is typically connected to the fresh water tank using inlet and outlet hoses. It’s also important to have an inlet filter installed to prevent debris from entering the pump and causing damage.

If you’re experiencing issues with your RV water pump, it may need to be primed. This involves filling the pump with water to create the necessary pressure for it to function properly.

Overall, understanding how your RV water pump works is essential for maintaining a steady supply of water while on the road.

Types of RV Water Pumps

When it comes to RV water pumps, there are two main types to choose from: demand pumps and bypass pumps. Each has its own unique features and benefits.

Demand Pumps

A demand pump, also known as an on-demand pump, is the most common type of RV water pump. It is designed to automatically turn on and off as needed, delivering a constant flow of water to your RV’s faucets and appliances. Demand pumps are typically powered by electricity and can be connected to your RV’s battery or electrical system.

One advantage of a demand pump is that it is very efficient, using only the amount of water needed at any given time. This can help conserve water and reduce your overall water usage. Additionally, demand pumps are often very quiet and easy to install.

Bypass Pumps

A bypass pump, also known as a manual pump, is a less common type of RV water pump. It is designed to be used as a backup in case your demand pump fails or is not working properly. Bypass pumps are typically powered by hand or foot, and must be manually operated to deliver water to your RV’s faucets and appliances.

One advantage of a bypass pump is that it does not require electricity to operate, making it a good option for RVers who prefer to boondock or dry camp. Additionally, bypass pumps are often less expensive than demand pumps and can be a good option for RVers on a budget.

Choosing the Right Pump for Your RV

When choosing a water pump for your RV, it’s important to consider your specific needs and preferences. Some factors to consider include:

  • How much water you will be using
  • Your power source (battery or electrical system)
  • Noise level
  • Ease of installation
  • Budget

By taking the time to research and compare different types of RV water pumps, you can find the one that best meets your needs and helps ensure a reliable supply of water for your RVing adventures.

Signs of RV Water Pump Failure

If you are experiencing issues with your RV water system, it may be due to a failing water pump. Here are some signs that your RV water pump may need to be replaced:

Low Water Pressure

If you notice a significant decrease in water pressure when using your RV’s faucets or shower, it could be a sign that your water pump is failing. This is because the pump is responsible for creating the necessary pressure to move water through the system.

Unusual Noises

If you hear unusual noises coming from your water pump, such as grinding or whining sounds, it could be a sign of a failing pump. This could be caused by worn-out bearings or other internal components.

Water Leaks

If you notice water leaks near your RV’s water pump, it could be a sign that the pump is failing. This could be due to a damaged seal or other internal component.

Failure to Turn On

If your RV water pump fails to turn on when you turn on a faucet or shower, it could be due to a faulty pump switch or blown fuse. Make sure to check these components before assuming that the pump itself is failing.

Failure to Turn Off

On the other hand, if your RV water pump fails to turn off after you turn off a faucet or shower, it could be due to a faulty pump switch or pressure in the system. Check the switch and pressure relief valve to determine the cause.

Clogged Strainer

If your RV water pump is working but you are still experiencing low water pressure, it could be due to a clogged strainer. Make sure to clean the strainer regularly to prevent this issue.

Grounding Issues

If your RV water pump is not working at all, it could be due to a grounding issue. Make sure that the pump is properly grounded to prevent electrical issues.
