How to Prime an RV Water Pump: A Step-by-Step Guide

How to Prime an RV Water Pump

If you’re an RV owner, you know how important it is to have access to clean water while on the road. However, sometimes the water pump can lose its prime, resulting in little to no water flow. Fear not, as priming your RV water pump is a relatively simple process that you can complete with just a few tools. In this guide, we’ll cover everything you need to know to prime your RV water pump and get your water flowing again.

Understanding the Importance of Priming an RV Water Pump

Before we dive into the priming process, let’s take a moment to understand why priming is necessary. Simply put, priming ensures that the water pump has water in it before it starts working. Without water in the pump, it will struggle to generate the pressure necessary to move water through the RV’s plumbing system. This can lead to low or no water flow, which is obviously less than ideal when you are on the road.

When you’re out on the road, you rely on your RV’s water system for everything from showering to cooking. Without a properly functioning water pump, you could find yourself in a difficult situation. That’s why it’s important to understand the importance of priming your RV water pump.

What is Priming?

Priming is the process of removing air from the water pump system and filling it with water, ensuring that the pump has the water it needs to function properly. Essentially, it’s like “prepping” the pump before you turn it on.

Priming can be done manually or automatically. Some RV water pumps have an automatic priming feature, which means they will automatically fill with water when they are turned on. However, if your RV water pump does not have an automatic priming feature, you will need to manually prime it.

Why is Priming Necessary?

Priming is necessary because RV water pumps are not self-priming. This means that they cannot generate the suction necessary to pull water into the pump on their own. Without water in the pump, it will struggle to generate the pressure needed to move water through the RV’s plumbing system. This can lead to low or no water flow.

Without proper water flow, you won’t be able to take a shower, wash dishes, or even use the toilet. That’s why it’s so important to make sure your RV water pump is properly primed before you hit the road.

Signs Your RV Water Pump Needs Priming

There are a few signs that your RV water pump may need priming. These include low or no water pressure, sputtering water flow, or a pump that runs but does not generate water flow. If you notice any of these signs, it’s time to prime your RV water pump.

It’s a good idea to check your RV water pump regularly to make sure it’s working properly. This will help you avoid any unexpected issues while you’re on the road. If you’re not sure how to prime your RV water pump, consult your owner’s manual or contact a professional for assistance.

Before you start the priming process, you’ll need to gather a few tools and materials. Here’s what you’ll need:

Basic Tools

  • A wrench
  • A screwdriver
  • A bucket
  • Rags

Optional Tools for Easier Priming

Safety Precautions and Protective Gear

Whenever you’re working on an RV’s water system, it’s important to take proper safety precautions. This means wearing eye protection and gloves, as well as ensuring that the RV’s power supply is shut off to prevent any electrical accidents. Additionally, make sure that the RV is parked on a level surface to prevent any accidents.

Additional Tips for Priming an RV Water Pump

Priming an RV water pump can seem like a daunting task, but with the right tools and some basic knowledge, it’s actually quite simple. Here are a few additional tips to keep in mind:

  • Make sure that the water tank is full before attempting to prime the pump. This will ensure that there is enough water to flow through the system.
  • Check the water pump’s manual for specific instructions on how to prime the pump. Different pumps may require different steps.
  • If you’re using a priming pump, make sure that it is properly connected to the water system before starting the priming process.
  • When priming the pump, be patient. It may take several minutes for the water to start flowing through the system.
    Once the pump is primed, turn on the faucets in the RV to check for proper water flow and pressure.
  • If you notice any leaks or issues with the water system, address them immediately to prevent further damage.

By following these tips and taking the proper safety precautions, you can easily prime your RV’s water pump and ensure that your water system is working properly. Happy camping!

How to Prime an RV Water Pump?

Turning Off the RV’s Power Supply

The first thing you need to do before priming your RV water pump is turn off the RV’s power supply. This will prevent any electrical accidents while you’re working on the water pump system. Make sure to also disconnect any external power source that may be connected to your RV.

Locating the RV Water Pump

The next step is to locate the RV water pump. In most RVs, the pump is located in a storage compartment or under a bench. Refer to your RV’s manual if you’re unsure where to find it. Once you have located the water pump, make sure that there is enough space around it to work comfortably.

Draining the RV’s Water System

Before you can start priming the pump, you’ll need to drain the RV’s water system. Start by turning off the water supply to the RV and opening all of the faucets and valves to let the water drain out. This will ensure that the pump starts with a clean slate and will fill up with fresh water when you start the priming process. Make sure to also drain the hot water tank to prevent any damage to the heating element.

It is important to note that if you have antifreeze in your RV’s water system, you will need to flush it out before priming the pump. This is because antifreeze can damage the pump and also contaminate your fresh water supply.

Inspecting the Water Pump

Before priming the water pump, take a few minutes to inspect it for any signs of damage or wear and tear. Check the pump’s wiring, hoses, and fittings for any cracks or leaks. If you notice any damage, it is best to replace the parts before proceeding with the priming process.

Priming the Water Pump

Now that you have turned off the power supply, located the water pump, drained the water system, and inspected the pump, it’s time to prime it. To do this, you will need to fill the pump with water. You can use a jug or bucket to pour water into the pump until it is full. Make sure that the pump’s inlet hose is submerged in the water.

Once the pump is full of water, turn on the power supply to the RV. The pump should start running and you should hear the sound of water flowing through the system. Keep pouring water into the pump until the water coming out of the faucets and valves is clear and free of air bubbles. This means that the pump is fully primed and ready to use.

Remember to turn off the power supply to the RV and disconnect any external power source once you have finished priming the water pump. This will ensure your safety and prevent any damage to the pump or RV’s electrical system.

Step-by-Step Guide to Priming an RV Water Pump

As any seasoned RV owner knows, having a properly functioning water pump is essential for a successful trip.
