How to Choose Best RV Water Pumps
Choosing the right Best RV Water Pumps model is essential for a stress-free travel experience. This appliance is designed to take water from your fresh water tank and pressurize your plumbing system so you can use your sink, shower, and toilet. For a more comprehensive understanding of how these systems work in general, review this comprehensive guide to RV water pumps. Who is it for? Any RV owner who plans to use their on-board fresh water tank, especially when dry camping or boondocking, needs a reliable pump. Selecting the appropriate model, however, is crucial; a pump that is too small will constantly cycle or deliver weak pressure, while an oversized one may draw too much battery power or be excessively loud.
Flow Rate (GPM)
The Gallons Per Minute (GPM) rating tells you how much water the pump can move. It matters because a higher GPM translates to stronger flow when running multiple fixtures, like a sink and a shower, simultaneously. For small campers, a 3.0 GPM is usually sufficient, but larger RVs or those with high water use should look for a 3.5 GPM to 5.5 GPM model for superior performance. Evaluate based on your expected peak water demand before purchase.
Pressure (PSI)
The Pounds per Square Inch (PSI) rating indicates the pressure the pump can maintain before the automatic shut-off switch engages. This is what determines the “force” of your shower. Most residential systems run at 40-60 PSI. For an RV, a 45 PSI shut-off is generally adequate, but to truly mimic a home shower experience, aim for a pump with a 55 PSI shut-off or a model with an adjustable pressure switch.
Noise and Cycling
Pump noise and cycling—the pump rapidly turning on and off—are common complaints. Cycling occurs when the pump’s pressure switch is too sensitive or the water volume is too low. Look for features like internal bypass technology (as seen in the SHURFLO models) or sound-absorbing mounts (like the Flojet) to minimize noise and prevent rapid cycling. This dramatically improves comfort, especially when using the pump at night.
Self-Priming and Run-Dry Capability
A self-priming pump can draw water up from the tank to start the flow without manual assistance, which is a standard and essential feature for any Best RV Water Pumps. The ability to “run dry” means the motor won’t overheat or burn out if your fresh water tank runs empty. Always prioritize models that explicitly state they can run dry without incurring damage for maximum longevity and peace of mind.
Voltage and Power Draw
The voltage is critical; most RVs use 12V DC pumps that run off the house battery, but commercial units (like the KENCIT) can run on 115V AC. If you boondock, pay attention to the pump’s maximum amp draw, as a higher draw will deplete your battery bank faster. Balance GPM/PSI needs with battery capacity. For optimal battery management, consider also reviewing the features of best RV battery charger maintainers.
Maintaining Best RV Water Pumps
To ensure the longevity and peak performance of your Best RV Water Pumps, regular maintenance is key. Before winterizing, always flush the pump and system thoroughly to remove any residue. Use a non-toxic RV antifreeze to protect the internal components from freezing damage. A common buyer mistake is ignoring the pump’s inlet strainer; this small filter needs to be checked and cleaned periodically to prevent debris from reaching and damaging the pump’s diaphragm or check valves, which are sensitive to grit and sediment.
Furthermore, checking all connections for air leaks is essential. Air leaks on the intake side can cause the pump to cycle constantly and eventually fail. Use Teflon tape or paste on all threaded connections. Proper installation, including securing the pump to a sturdy surface with vibration-dampening material, will significantly reduce noise and extend the pump’s operating life. A well-maintained pump will provide a stable water supply for your RV for many seasons.
How to Use Best RV Water Pumps
Here are the practical usage steps for your fresh water pump:
- Step 1: Setup/prepEnsure your fresh water tank is at least partially filled. Verify that the pump is properly wired and that the inlet hose is fully submerged in the tank. If applicable, close the low-point drains and the city water inlet valve.
- Step 2: Core usage & best practicesTurn the pump’s power switch on. Open the highest faucet (usually the kitchen sink) to bleed all air from the water lines until a steady stream is achieved. Close the faucet. The pump should run briefly to build pressure and then shut off, indicating a properly primed system. It will now turn on automatically when you open any fixture.
- Step 3: Optimization/safety/maintenanceListen to your pump. If it runs continuously or cycles on and off rapidly when no water is running, check for a leak in the system or air in the lines. Always turn the pump off when leaving the RV or when the fresh water tank is empty to prevent dry running for extended periods, even if it has a run-dry feature.
- Step 4: Troubleshooting & pro tipsIf your pump is making excessive noise, check if it’s securely mounted and consider adding sound-dampening pads or flexible water hose connectors instead of rigid pipe connections. For low flow issues, check the intake strainer for clogs before assuming the pump has failed.
Frequently Asked Questions
Why is my Best RV Water Pumps constantly cycling?
Constant cycling usually means there’s an air or water leak somewhere in your plumbing system. Check all connection points for drips or looseness, especially at the pump’s intake side. It could also mean the pump’s internal check valve or pressure switch is worn out and needs adjustment or replacement to maintain the pressure seal.
Can I run my Best RV Water Pumps with city water hooked up?
No, you should always turn your pump off when you are connected to city water pressure. The city water connection provides its own pressure, and running the on-board pump simultaneously can potentially damage the pump itself or overload your RV’s plumbing system. Always use one water source at a time.
What GPM is best for my small RV?
For a smaller RV or camper with one or two fixtures, a 3.0 GPM pump is typically the best and most efficient choice. This flow rate provides a good balance of pressure and battery usage. You will only need to consider a higher GPM if you plan to frequently run a shower and sink simultaneously.
How often should I replace my Best RV Water Pumps?
The lifespan of a pump depends heavily on usage and maintenance. A well-maintained, high-quality diaphragm pump can last 5 to 10 years or more. Premature failure is often due to running dry frequently, not cleaning the strainer, or internal damage from freezing during winter.
How do I winterize my Best RV Water Pumps?
To winterize, first drain the fresh water tank. Then, either use the pump to draw RV-specific, non-toxic antifreeze through the system (following the manufacturer’s instructions) until it comes out of all faucets, or bypass the pump and use compressed air to blow out the lines completely, making sure to protect the pump’s head.
Final Thoughts
Choosing the right pump is the single most effective way to improve your RV’s water system. We’ve explored a wide range of Best RV Water Pumps, from high-pressure 55 PSI units to high-volume 5.5 GPM models, and the key takeaway is to match the pump’s specs to your rig’s size and your personal water needs.
