Guide: Finding The Best RV Water Pump Before Your Trip

Water pumps are essential to the function of your recreational vehicle, especially if you are camping far away from a water source. Water pumps draw water up from your water tanks underneath your RV and pump the water throughout the RV; to your sinks, toilets, and showers.

Water pumps are typically powered by 12-volt batteries and do not need electricity to function.

Choosing the right water pump for you RV sounds like a daunting task, but with the right information and product suggestions, you will find recreational vehicle water pumps are easier to understand and install that you might have thought.

Types of Water Pumps

There are three main types of water pumps that are helpful to know about when shopping for your RV. Shurflo, Flojet, and Bayite are the most commonly used and easy to understand water pumps. They are all very similar in the way they are set up and function. There are some differences you need to be aware of to buy the right pump for your RV, though.

The main differences between these three types of water pumps lie in their Gallons Per Minute (GPM), Pounds Per Square Inch (water pressure or PSI), and Amperage (strength of electric current or AMP) measurements. Each recreational vehicle is different, so make sure to check what requirements your RV requires for water pumps.

Otherwise, you risk damaging your pipes with too much pressure, electricity usage, and low water flows to all your outlets.

What To Look For In A Water Pump

Before you start shopping around the internet for your water pump, you need to know what you are looking for in a water pump as far as specifications go. Questions you should ask yourself, or your prospective water pump candidate, before you buy is include:

Does the water pump come with a manual?

It would be a shame to have your water pump arrive at your house, go to install it, and have there be no instructions. Not only do owner manuals help with installing your equipment, but they also help educate the owners on care and maintenance of the water pump.

How many gallons of water should your RV produce to function comfortably?

Check with your manufacturer for information on the correct water usage your RV can handle. This is important for both your water consumption and understanding of which pump to buy. When shopping for your water pump, the answer will fall under the Gallons Per Minute product description category.

Dimension, Weight, and Power

Check your old water pump to make sure your new one will fit. Check to make sure you are buying a water pump that is the same size and weight as your old one. Also, make sure it produces the same PSI and Amperage recommended for your specific RV. You don’t want to ruin your plumbing!

Product Warranty

Lastly, you want to check and make sure that the company you are buying your water pump from includes a warranty. This is a good precaution in case your pump becomes damaged for any reason.
