RV Water Pump Basics

What is An RV water pump? 12 Volt water pump?

To put it plainly, an RV fresh water pump is a pump that is designed for use in recreational vehicles such as campers, travel trailers, and motorhomes. The device’s job is to bring fresh water from a storage tank to shower heads, sinks or toilets. 

Water pumps for campers are typically 12 volt pumps, and as the name suggests, they wire directly into the 12 volt system of the RV. 

These are different from a 110V water pump or 120V RV water pump, which are generally designed for residential purposes and generally installed in homes. While a 12 volt water pump for RV obviously doesn’t pump water with the same high pressure as larger residential models, they get the job done for recreational vehicles.

While 12 volt water pumps work with a variety of power sources, including electric, solar and fossil fuel, RV electric water pump is by far the most common and easiest to maintain type, especially while traveling.

How does an RV water pump work?

An RV water pump consists of several components: a pump itself and the fittings which are required to hook up to your RV’s water system and the wires to hook up to the 12 volt electrical line of your RV system. 

The fittings can come either as a threaded type unit. This one attaches with wing nuts, and can be a bard, either a straight or an elbow and the other one uses fittings called a squad port which works by having a couple of O-rings on the bottom of this fittings.

They literally plug into the pump and lock in place. The quad ports are also available in a variety of threading types of even bards, elbows or straights.

In the course of operation, water pumps for RV draw water from the storage tanks and distribute it throughout your RV to the water appliances.

These pumps usually work on-demand, thus are also called 12 volt on demand water pump. There is a pressure switch on the head of the pump which allows it to turn on and off automatically based on the operation of the appliances. 

For example, when you open the faucet in the galley, the switch is going to tell the pump to turn on, and when you close the faucet it tells the pump to turn off.

Benefits of an RV water pump

  • Save space inside recreational vehicles: Compared to the traditional water pumps, water pumps for recreational vehicles are relatively small and lightweight. Hence, such pumps allow RVers to preserve space which is by all accounts a luxury. 
  • Maintain a constant water supply: With a 12 volt on demand water pump onboard, you could keep the water appliances of your rig running around the clock. That is by all accounts a big plus since your level of comfort on the road would be greatly enhanced. 
  • Open up additional travel options: If you secure a solid water pump for your rig, you don’t have to worry too much about water supply as you plan your trips, compared to the worst case scenario of having to rely on expensive bottled water. As a result, you should be able to try out previously unconsidered routes and gain new experience in the process.
  • Simple installation: Unlike the more complex residential water pumps, RV water pumps are easy to install, even a beginner camper can do it. The only thing you need to do is simply consult the manual.

Top-Rated RV Water Pumps

Due to individual liking, the best RV water pump to certain RVers could appear mediocre to others but you should pay attention to the models below if you want to get your money’s worth.

1. Shurflo 2088-554-144 – Best  Of The Best

Shurflo 2088-554-144
Check prices and reviews

Specifications:

  • Flow Rate: 3.5 GPM
  • Dimensions: 8.5 x 4.5 x 5 Inches
  • Weight: 4.8 Pounds

Why This Is The Best

As an RV on demand water pump that could be mounted vertically as well as horizontally, Shurflo 2088-554-144 works well in various settings.

Compact and light, the water pump made by Shurflo proves to be a breeze to set up and it has rather undemanding maintenance requirements too.

Because of that, Shurflo 2088-554-144 is considered to be the best RV water pump on the market for casual excursions nowadays.

The Shurflo pump is also offered at an affordable price so it suits the shopping budgets of lots of people.

Surfaces that come into contact with water in Shurflo 2088-554-144 are made of polypropylene/santoprene so the water that it delivers is safe for human consumption.

Since the water pump from Shurflo employs a thermally protected motor, overheating is going to be less of an issue.

Shurflo 2088-554-144 incorporates a solid check valve as well, hence, enthusiasts of RVing don’t have to worry about reverse flow.

Boasting a flow rate of 3.5 GPM and a pressure limit of 45 PSI, the pump of Shurflo is capable of keeping water running around the clock.  

In terms of post-purchase support, Shurflo backs its water pump with a decent 1-year warranty that covers manufacturing defects.

If you like to have an insurance policy while buying things, you should think about adding Shurflo 2088-554-144 to your shortlist.

Finally replaced my aging SHURflo 2093-544-114 in my Lance truck camper. This new pump holds pressure longer and the pump turns on less than the old one as it brings lines back up to pressure much faster. This pump is actually very quiet and efficient. Wrapping the water lines in foam is the secret to reducing the vibrating sound created by all 12v water pumps. Now there is ample pressure for a nice shower.

Simple to install. Release pressure on water lines and unscrew hoses attached to old pump. Unscrew the four screws holding old pump to wall under the sink and remove. Attach hoses to new pump and screw pump back onto wall under the sink.

Using a cordless power drill with a phillips screwdriver bit makes this install much easier as there is often little room to get your body and arms inside the cabinet to turn the screws. Buy on Amazon and easily install this yourself and you will save money on not only the pump but the labor costs at your local RV service center. I saved $20 on the pump and at least $85 for an hour of labor at local RV store.

The old pump lasted 20 year and I expect this new pump will give me the same or even better service life.

This worked great for pumping water into an RV tank. Where we camp, there are no hook-ups, so I connected a hose on either end and used this to pump water from portable water containers into the RV using a hose connector. It was pretty fast and easy to use. I had to pour water into the hose going to the pump first to get it primed, and then it worked great the rest of the way.

Buying an RV Water Pump: Key Criteria to Consider

To get the best RV water pump for your rig, you must consider these most important buying criteria before making a purchase. That said, if you’re limited by your budget, choose a model that offers the best balance of different features and benefits. After all, the best RV water pump really depends on your budget and water consumption needs, which might depend on factors such as the number of companions you’re travelling with.

Gallon Per Minute (GPM)

As RVers count on the pumps to deliver water to multiple amenities throughout the vehicles, GPM is deemed to be one of the top concerns. By checking out the GPM rating of a pump, you could tell how much water it’s capable of supplying. Pumps on the weaker end may have GPM ratings of 1.2 or so, while the best RV water pumps would typically have a GPM ratings of more than 4, making them 12 volt high volume water pump.

In the case that the water consumption of your rig is moderate, you may settle for a standard water pump. On the other hand, if the amenities on your rig require lots of water then it’s strongly recommended that you prioritize high GPM models.

Pounds per square inch (PSI)

PSI is another measure of pressure rather than flow. RV plumbing systems are built to handle pressures between 40 and 60 PSI, so it’s best to get a 12 volt water pump with a PSI within that range. Any pumps that advertise a higher pressure rating than 60 PSI might cause damage to the pump itself and your RV plumbing system.

Amperage

Amperage, or amps, is another metric you should pay attention to when hunting for the best RV water pump. It measures the amount of electricity a water pump needs to draw in order to work. If you need to power many energy-consuming appliances in your rig, you might want to double check that your power sources can handle the daily total amps drawn. While most RV water pumps draw very little electricity, 12 volt high volume water pump can draw up to 15 amps of power.

Size

In the average recreational vehicles, space is limited which is why it’s essential that you pay attention to size while shopping for a pump. The last thing you want to spend your money on is a huge travel trailer water pump that your modest rig is unable to accommodate. So as to grab a fitting pump, you should think about the available space inside your rig and decide accordingly. Until you know for sure that you have the space for the pump you like, avoid committing to a purchase.

Ease Of Installation

Technically, it’s fine to drive your vehicle to a nearby workshop and let the professionals take care of the pump installation in your stead. Still, as an RVer, you likely have to deal with many expenses so why don’t you pick up a camper water pump that you could set up by yourself? By installing the pump on your own, you would save some bucks for more pressing needs and potentially learn how to perform proper maintenance too. To determine the installation complexity of a particular RV pump, you must assess its design and read reviews of customers.

Voltage

Typical RV water pumps run on electricity so before you put a certain pump in your vehicle, don’t forget to check its power requirement. Today’s market contains two lines of water pumps for recreational vehicles: 12V and 24V. Your choice will depend on the amount of water you need pumped and the size of the RV. 

Keep in mind that a 12 volt unit is more manageable as it draws less power from the system and generally does its job in the RV setting. A 24 volt pump translates to high volume, but it could drain your RV’s battery or generator.

All in all, having a strong pump is pointless if you fail to keep that pump powered adequately in use. Thus, to find the best RV water pump for your vehicle, you have to take into account its power supply.

Automated Pump Cycle

The best RV water pump should start pumping once the pressure goes below the preset level  and also stop pumping automatically once the pressure reaches the preset level. This automation, or automated on-off cycling, allows for consistent performance. 

If your pump does not cycle on and off as demand arises, it will continue to run when it isn’t really needed, which can cause damage to your RV’s plumbing line and also significantly increase your energy consumption.

In the long run, a pump that continues to run all the time will have a much shorter life than one that cycles on and off as needed.

Noise Level

So you wish to enjoy your outdoor experience in peace? Then you need to consider giving noise level some thoughts. All pumps make sounds during operation, especially during pump cycles, but plenty of models nowadays control the noise relatively well. To get a quiet RV water pump, it’s key that you keep an eye out for models that incorporate specialized noise-reduction materials as well as low-vibration mount. 

There are useful tips to make your pump run more quietly too. Sliding a small pad beneath the pump before securing the screws down is a simple yet effective way to minimize vibration when it’s running. Another simple tip is to not overtighten the screws.

Some pumps run noisily as they cycle rapidly. This is usually caused by a low-pressure setting and can be fixed with a minor clockwise turn of the pressure adjustment screw. Only remember to adjust this setting until your pump turns off for at least two seconds between cycles.

Self-Priming

Unlike residential models, RV water pumps are engineered so that they can receive water from a limited water source. The best RV water pump should have self-priming feature, which will allow it to pump water from the tube even when the water supply is running low. Also, this feature will prevent the pump from getting damaged even when it’s running dry.

Different Types of 12-Volt RV Water Pumps

As mentioned above, 12 volt water pump for RV can be categorized by its power source, including fossil fuel, solar power and electricity. Another way to differentiate them is by their pumping speed. 

Constant speed

The most common type of 12 volt water pump for RV is the constant speed pumps, which, as their name suggests, deliver water at one speed only. Basically, these pumps are either off or on. 

Variable speed

Variable speed pumps, on the other hand, can create water pressures similar to that in your home. Their built-in pressure sensor adjusts the speed of the pump motor to ensure the water is delivered at a constant pressure. 

In addition to this advantage, they also tend to be quieter, although you’ll have to spend more for these benefits compared to their constant-speed counterparts.

High volume

Finally, 12 volt high volume water pump models are designed to deliver water at a higher rate of flow than the standard 12 volt water pumps that come built-in on most RVs. 

A pump is considered “high volume” if it’s got a flow rate of more than 4 gallons per minute (GPM). To achieve this, they typically require more electricity to operate, so they’re usually found only on larger, 50-amp rigs. If you travel often and with companions who might wish to use water at the same time, getting a 12 volt high volume water pump will be ideal.

For your information, there are also 24-volt pumps typically installed in trailers, buses, and trucks that have higher water pressure for more heavy-duty tasks. However, they will take a toll on your RV’s power. This is why 12 volt pumps are the most common type for RV you will come across.

How To Install An RV Fresh Water Pump

To be on the safe side, it’s best that you follow the user’s manual that accompanies your water pump while setting it up. That being said, if you need a general installation guide, check out the following steps.

Step 1: Drain The Water Tank

You must connect a hose to the base of your water tank and proceed to drain it all the way. It’s a good idea to direct the hose to a drum so you could reuse the water once you finish setting up your pump.

Step 2: Remove The Old Pump

First, you should disconnect your old pump from the battery bank by removing the wires. Next, you need to pull out all the hoses connected to the pump as well. Following the removal of the wires and the hoses, you have to work on the securing bolts and screws that fix the pump in place. After everything is out of the way, gently lift the pump out of your RV.

Step 3: Secure The New Pump

Put the new pump into the position of the old pump then bolt it down. Additionally, you also need to wrap up the pipe threads with some Teflon seal tape.

Step 4: Reconnect The Wires/Hoses

If the pump seems to be well-secured then you could start reconnecting the wires as well as the hoses. For good measure, it’s strongly recommended that you check all connections again at the end prior to moving on.

Step 5: Test Out The Pump

Your water new pump should be operational at this point so you only have to flip the power switch and see how things turn out. Pay attention to odd sighs and make corrections if necessary.

FAQs About RV Water Pumps

1. What exactly is an RV on-demand water pump?

To put it plainly, an on-demand water pump is a pump that kicks on the very moment water is demanded and moves that water from a storage tank to the intended point of use. It has a control unit built inside so it knows exactly where water is needed. The operation of on-demand pumps is based on the pressure in the water pipes.

As people open faucets, flush toilets and so on, RV on demand pumps would continue to supply water until pressure in the pipes returns to a predetermined parameter. Depending on the models, the pressure threshold could be adjusted up and down.

2. Will an RV water pump affect flow rate?

The answer to that is yes. The RV pump is what creates, pressurizes and make the water move. So the rating on the pump says 5 gallons per minute or 3.5 gallons per minute is the output capacity of the pump. Once you hook it to your distribution system, chances are you’re not gonna get 5 or 3.5 GPM because the water’s gonna travel through pipe, it’s gonna travel through elbows, fittings and your faucet fixtures. The important thing is that you have enough flow, enough pressure to make it workable in your RV.

3. How long does an RV water pump last?

A 12 volt water pump for RV typically lasts up to 10 years, and the best RV water pumps with solid construction can last well beyond that mark, given that you have installed and used it correctly and give it proper maintenance. 

Sometimes, though, it just depends on pure luck. The best you can do is get a model with good reviews, from a prestigious manufacturer and with a fairly long warranty, which by the rule of thumb is a good measure of the product’s functionality and durability.

4. How do I prime my 12V RV water pump?

You may need to prime your RV water pump after replacing it, or if your RV’s been out of use in storage for quite some time. The process is simple, as follow:

  1. Fill up your fresh water tank.
  2. Turn on the cold water faucets in your RV, make sure they are completely open.
  3. Switch on the water pump near your RV water tank.
  4. This should prime the pump by pushing water up from the tank through your faucet. Let the water flow a while, then turn the faucets off. Note that air must be completely removed from each and every faucet. You can do this by opening and closing the faucets, as well as the showerhead and toilet, one at a time to run water through each. 
  5. Your pump will be fully primed when the water pump only turns on when a faucet is actually open and not in between.

5. Why does my RV water pump pulsate?

Your RV water pump uses pressure switches to start and stop working. If this switch is not set properly, pulsations occur. The more sensitive the pressure switch is to the change in pressure caused by turning on the faucet, the fewer pulsations. Most pumps have an ideal setting that can minimize or almost eliminate pulsations. 

To make the switch more sensitive to the change in pressure, make the pump start quicker and run longer. The water pressure will therefore stay steadier, reducing the frequency of pulsations. 

6. Can I leave my RV’s water pump on?

Yes you can. As it is a pressure sensing device, the water pump will only turn on when there is demand for water, and it only pumps water on demand. 

It’s good to know though that many RVers recommend turning the pump off at night to prevent possible sleep disturbance. Every couple hours or so the pump relaxes it’s pressure just enough to run the pump for a second to bring the pressure back up, which can disturb the light sleepers.

7. Symptoms of a bad or failing RV water pump?

The most common symptoms that your water pump is not working properly and might need replacement are:

Runs when not in use: If your water pump continuously runs or keeps cycling on and off when not in use, while you have confirmed that water is available to the pump, the pressure switch might be faulty. Or else, This might be due to something as simple as a loose connection or a crack in one of your plumbing lines.

Pump runs but no water from faucets: Ater making sure that there is actually water in your freshwater tank, check all the water lines that lead in and out of the actual water pump. Look for loose connections and worn, split or cracked lines.

Next, check if there is any problem with the plumbing lines by seeing if there is water flowing to the pump. Start by carefully loosening the water line to the pump. If you disconnect it and the water line seems dry, then the issue is the actual water line coming to the pump from the tank. Deal with any type of blockage or tube damage. 

If there is still no water, the problem lies with the pump itself. Examine it to see if the motor is faulty and needs to be replaced, or else you will need to replace the whole unit. Especially when another assistant turns the water pump on again, and the water only comes out in small drips, you most likely need to get a new water pump. 

Excessive and unusual noise: Most of the RV pumps have a multi-chamber diaphragm design which over time can become corroded or calcified rendering them inoperable. Improper winterization can also damage the diaphragm creating increased noise and very low water pressure. Otherwise, the culprit might be motor failure.

Leaks: In this case, check the fittings and connections as well as the pump housing to make sure the issue is indeed caused by the pump and not something else in your plumbing line.

Won’t Turn On: First, make sure you didn’t leave the drain open when you meant to be filling up the fresh water tank. Next, check your 12 volt fuse panel, then move to the pump and look for the possible use of an inline fuse. Next, check the electrical connections on the pump and then move to the pump switch to see if it’s still functional. Then, use a multimeter to check if power is actually making its way to the pump. It might be that you winterized your RV last winter, now it’s spring and the pump is not working. In this case, make sure you reconnect everything correctly after you pumped RV antifreeze through the water lines. If nothing resolves the problem, it’s time you get a better RV water pump replacement.

8. How to quiet a noisy RV water pump?

To silent a loud pump, you have lots of options. By slipping some foam pads under the pump, it’s possible to isolate the vibrations and keep the noise down.

In the case that source of noise seems to be rattling water pipes, you should wrap foam pads around them. Many pump manufacturers also sell dedicated, purpose-design pump silencers that let you reduce the noise level of your pump.

9. How keep a water pump in good condition?

Just like every other device, RV water pumps require periodic maintenance in order to stay in top shape. To preserve a consistent flow of water, you should remove and clean the filter of your pump now and then.

If you often let your RV sit idly for months, it’s essential that you sanitize your pump at intervals to remove algae build-ups. Finally, during winterizations, stick to nontoxic antifreeze to protect the integrity of your pump.
