The Best 12-Volt RV Water Pumps

In this day and age, clean running water while camping is no longer a luxury but a necessity. RVs have sinks, faucets, and showers for a reason, and you need something reliable and durable to send water to these appliances. There’s nothing like quick access to drinking water or dish washing water from your sink or having a luxurious shower in your RV instead of having to trek to those campsite restrooms that are often barely tolerable and full of bugs and dirt (and who knows what else). Not all water pumps are created equally, so read on to see which products make the list of our top 12-volt RV water pumps.

Our pick for the best overall 12-volt RV water pump is the Shurflo 2088-554-144 Fresh Water Pump. This company has long been designing and manufacturing water pumps for RVs, campers, and boats, so it knows what works. Constructed of high-grade stainless steel, this durable water pump will withstand degradation in harsh environments and should work reliably for years. This water pump operates in a very energy-efficient manner off your 12-volt supply and can pump an impressive 3.5 gallons per minute as 45 PSI. It boasts a thermally-protected permanent magnet motor for added longevity and efficiency. This RV water pump is equipped with a smart check valve that ensures one-way operation and prevents any backflow. Its compact size allows it to fit in tiny spaces and to run quietly and unobtrusively.

Our award for the best value in a 12-volt RV water pump has to go to the Bayite 12V DC Fresh Water Pump. This pump promises to draw low current, but still deliver a consistent and smooth flow of water through all ranges of operation. This pump is a self-priming pump that offers a positive displacement and can even run dry without shorting out or breaking down. The pump is well-sealed to prevent dirt, dust, debris, and moisture from entering its housing and damaging performance. This water pump comes with easy connection fittings included, so installation is a breeze. A durable electro coating and sealed switches ensure quiet pump operation and years of resistance to corrosion and rust. This water pump delivers a respectable flow of 1.2 gallons per minute at 80 PSI.

If you’re in the market for an easy-to-install, low-maintenance 12-volt RV water pump, consider the SEAFLO 42-Series Water Pressure Diaphragm Pump w/Variable Flow. As its name suggests, this pump is made to withstand the harsh, salty, unforgiving ocean environment and is a top pick for boaters and sailors. You can be assured that it will deliver above and beyond the needs of your RV or camper (or boat). Offering a strong water output of three gallons per minute at 55 PSI, this 12-volt water pump is one of the stronger ones currently on the market and will deliver water to wherever you need it quickly and efficiently. It’s backed by an impressive four-year warranty, which is one of the best in the business. It’s also self-priming and capable of running dry without breaking down.

If you are in the market for a heavy-duty, no-nonsense pump that will deliver a strong performance, check out the Flojet 03526-144A Triplex Diaphragm Automatic Water System Pump. This 12-volt RV water pump is one of the toughest on the market. Delivering water to you at 2.9 gallons per minute at 50 PSI, this pump is fast and strong. It has a self-priming capacity of up to nine feet suction lift and a quadruple piston system to ensure maximum functionality. Equipped with a built-in bypass to decrease pulsation, and soft, supportive, noise-absorbing mounts, you will barely be able to tell when this pump is running. This pump is available for purchase in 1-, 2-, 3-, 4-, or 5-pack quantities, so you can replace all your water pumps at once or keep extras on hand just in case.

The Amarine Made 12v Water Pressure Diaphragm Pump certainly deserves a spot on this list. While it won’t blow you away with power, you can’t argue about the price of the unit. Just because you’re on a tight budget doesn’t mean you can’t have running water. This handy little water pump delivers 1.1 gallons of water per minute at an operating pressure of 35 PSI. It’s great for smaller RVs, boats, campers, and vans. And like many of the bigger, more expensive pumps on the market, this water pump is also self-priming and includes run-dry capabilities to ensure safe operation for a long time. The company promises that its pumps all undergo rigorous testing prior to leaving the factory and notes that your pump may arrive with a little water already inside because of this.
