What You Should Pay Attention To When Buying Best RV Water Pump
The Manner of Installation
To start with, you need to pay attention to the manner of installation. Be assured that the setting-up of a chosen model is simple and not time-consuming. Take a compact model without many unusable additional details. You can’t waste your time on this, are you? To install your RV water pump you will need to read instruction, manuals, or watch videos on the Internet. If possible, go for small-sized and compact RV water pumps because many noticed how easy it is to install them. These small pumps only have minimal usable parts in the sense that it won’t take a lot of your time.
They are also lightweight plus easy to transport to the specific spot you intend to install them. Make sure, however, that you have all the materials and supplies needed for the installation, including a water hose, Teflon tape, and screwdriver.
Motor
The second, but no less important part is a motor. The power of the motor defines the strength and durability of a pump. Also, motor thermal protection defends it from its overheating. The most recommended way for you to understand water pumps on a better level is to look at its specs and look at the number of gallons it can pump every minute. You should also check the statistics of the PSI for a better idea, but it is simpler to understand the physics of gallons that gets pumped every minute. Normally, you are going to look for something that pumps about 3 gallons each minute for good power.
GPM
GPM stands for gallons per minute. It refers to the number of gallons per minute needed by your pump to supply into your RV. Avoid getting an extremely powerful one, though.
It is because bigger pumps that work harder might cause them to draw too much power from your RV’s batteries. A large one might also drain the electric system of your vehicle. You can choose smaller water pumps that are as effective as the bigger models.
PSI
PSI actually stands for pounds per square inch. This is the water pressure recommended for your RV. You have to know the safest pressure required by your rig. One standard rule is to stick to the safe range, which is actually around 60 to 75 psi.
Noise Level
Your water pump must operate quietly. Water pumps tend to produce some noise when it operates because of the motors incorporated into them. That’s the reason why you have to assess the noise level of the water pump you are eyeing to buy before investing your money in it. In some pumps, a noise-absorbing mounting system is used to minimize the loudness. In order to lessen the noise of a tank pump that is free-standing, you can buy or make a pump cover to seal it off. A cover becomes the pump protector from elements, muffle, and the noise. Although, make sure the cover is enough to let air flow in so the pump will not overheat. Most water pumps have an internal bypass function for low-cycling, which prevents the pump from loudly turning on and off repeatedly during periods of low water flow. RV water pump is also a self- priming device. For the layman who doesn’t know much about self-priming and internal bypass systems, the pump is quiet.
Energy Draw
Remember that when a water pump operates, it tends to consume a specific volume of electricity. With that in mind, check the energy-efficiency of the pump prior to buying. Even if it is tempting to pick the largest and powerful pump you can find, it is significant to remember that pumps need to draw energy when the tap is on. The quieter a water pump is, the less energy it consumes. As a result, the pump is able to operate without having to draw power too frequently. So, purchasing a water pump that is too strong for your goals, may have a negative reflection on your electricity and water bills. To lessen the usage of energy, you need to lessen how many times your pump has to be activated. This can be made possible by having a gravity feed system, a pressure tank, or a header tank system.

Vertical Suction Lift
Suction lift refers to the pressure (negative pressure) on the suction side of the pump. It relates to the amount of water the pump needs to function. This factor requires you to take into consideration the specific amount of water required by your water pump in order for it to operate efficiently. If you wish to pump a minimal amount of water efficiently then choose a pump with little lift. If you want to drain a flooded area, for example, you have to search for a unit with as little lift as possible to promote ease in draining all the water left. This is an important issue when buying a 12-volt water pump for RV.
We are going to look at water pumps that can be used for a variety of purposes. Whether you need to drain a pool or remove standing water from your home, these pumps can come in handy during times of need. Not only will we show you some of the best home water pumps on the market, but we will go over the most important features you should be paying attention to when making a final decision.
There are a few manufacturers of on-demand water pumps – most of which produce 12-volt water pumps for both the RV and the marine markets. Most 12-volt electric water pumps work basically the same way – they are constant speed pumps that are either on or off. There are a few more expensive RV fresh water pumps that are variable speed, which makes for quieter operation (less, if any, pump cycling or ‘hammering’) and a constant supply of water (no pulsing).
There are some brands that are more popular in the RV market, including Flojet, SHURFLO (Pentair), and Aquajet (Remco), while other brands cater more towards the marine market (SEAFLO). We have chosen one RV water pump from Flojet, two RV water pumps for our ‘best of’ from SHURFLO pumps and one from Aquajet, based on personal experience, consumer reviews, price, popularity, and other factors as noted in the below RV water pump reviews.

Varieties of pumps
To determine the principle of operation of the pump, it is important to understand the varieties of devices. It is by the mechanism of operation of pumps determine the type of unit. The following varieties of pumps are distinguished:
- centrifugal;
- vibratory;
- vortex.
Depending on the method of installation and type of operation, submerged and surface devices are distinguished. The main difference is that surface pump devices are installed on the surface. This version of the unit is suitable, for example, for organizing irrigation systems.
Submersible devices are installed into the water. They are suitable for operation in water to a maximum depth of 10 meters. The limits of immersion are fixed by the technical parameters of the device. On sale, you can also find advanced pumps for immersion up to 80 meters. Such devices most often have the function of protection against the dry operation. In the case of emptying the well or lack of water, the device automatically turns off. Due to this, it is possible to avoid the failure of pumps. Submersible devices are used for installation with the purpose of pumping large amounts of water on a permanent basis.
All pumps are divided into domestic and industrial. First of all, they differ in cost. Industrial devices are much more expensive, so they are used only in case of urgent need with high-performance requirements.
According to the type of the working element of the device are:
Vane. In such devices, a wheel with vanes, which are constantly rotating, is installed inside the pump. Due to this, water is pumped. This type of device is used for vortex and centrifugal devices.
Vibrating. In such devices, there are no moving elements. The pump works on the principle of a reciprocating system. Due to this, there is a movement of water. The principle of operation of such pumps is determined by an electromagnetic field.
Centrifugal pumps
Centrifugal water pumping devices are highly efficient and powerful. Working with a high head, these types of water pumps perfectly cope with the task at hand. Due to this, the devices are considered very popular in the market.
The structure of the centrifugal pump includes the following elements:
- The body, which can be made of different materials. For example, cast iron or bronze, steel or brass;
- Electric motor;
- An impeller with vanes.
The design of the centrifugal pump determines the principle of its operation. The centrifugal force created in the working part of the pump contributes to the movement of water. In this case, the system works as follows: the water enters the housing, and then is pushed into the water supply.
Centrifugal water pumps differ in manufacturing materials, technical parameters, configuration and other criteria. The popularity of this type of device caused the appearance of a large number of modifications on the market:
- by type of operation – submerged and surface;
- position – vertical and horizontal;
- single-stage or multistage.
When choosing water pumps, the type of material is necessarily taken into account. It must be strong enough to withstand loads and exposure to water. Centrifugal pumps are considered durable, reliable devices. The advantage is that the units can operate in different temperature ranges. They are relatively inexpensive, so you can easily solve the problem of pumping water without significant financial costs.
Vortex pumps
These water pumps have an inherently high head. They work for the purpose of pumping water quickly. The principle of operation is determined by the creation of a vortex from the water flow. Despite the compact size of the devices, it is possible to ensure fast pumping of water. These units are not used for pumping contaminated water with impurities. Vortex pumps have strengths and weaknesses, based on which you can determine the rationality of the use of devices for a particular purpose and conditions.
The pluses include the small size of the device. The head of the vortex pumps exceeds the centrifugal pumps by 3-5 times. Due to the simple design, all the parts can be serviced and replaced in case of failure. Among the disadvantages of the devices are sensitive to mechanical elements that can be found in the aquatic environment.
Vibrating pumps
Vibrating pumps are used for watering gardens and providing water. The principle of operation of a vibration pump is to create a magnetic field. It affects the coil and the core. These structural elements begin to change. Thus, the core has a metal structure. When bent, it creates a low level of pressure. When water enters the system, the structural elements take their original form.
Vibrating pumps can pump even dirty water with impurities. This property is considered key for vibration devices. The design of a water pump eliminates interacting parts. They do not wear out, so the water pump is considered durable.
The disadvantage is that the vibration pump will not be able to work in case of voltage fluctuations. When installing such a device, it is important to take care of the uninterrupted operation of the system. To do this, you can install a stabilizer that will be able to regulate the voltage level.
How to choose a water pump?
The choice of a water pump depends on the solution of your main task – pumping water. A competent approach when choosing a device determines the power, the speed of pumping water, productivity. There are a number of parameters on which it is worth focusing when choosing a pump for a well:
- The maximum level of head. It also determines the power and height to which the water pump will be able to lift water;
the volume of water. This is the amount of water that the pump will be able to pump per unit time. Most often, this parameter is calculated in units of cubic meters per hour; - Power. Determines the economy of the device;
water contamination level. Determines whether the device can be used to pump dirty water. Also may indicate the maximum size of the allowable fraction to be pumped.
It is important that as the pumping speed increases, the head height decreases.
Depending on the conditions for pumping water, you need to determine the most suitable unit. Vibrating pumps are best at lifting water to the proper height. Centrifugal pumps are not capable of pumping large volumes of water. If pumps have moving elements in their design, there are risks of damaging them if large particles get in. The most popular and versatile pumps for private homes are considered centrifugal models of units.
Prices for water pumps depend on the technical parameters, the method of installation, speed and the amount of water pumped per unit time.
How do they work?
An RV water pump usually has two ports; an inlet and an outlet. When the RV pump starts and runs, the diaphragm expands to draw water from the RV tank into the inlet port.
As the water flows through the pump, the diaphragm contracts, forcing the water through the outlet or pressure line at a higher pressure.
The pressurized water is then distributed through the piping system, which is connected to your shower, sink faucet and toilet bowl.
The average RV comes with a 50- to 200-gallon tank of freshwater. This water is your lifeline when traveling or camping without a power connection. Your ability to consume water from your tanks is connected to a little wonder known as an RV water pump.
The RV water pump has two basic functions:
Task #1
The first task of an RV water pump is to deliver pressurized water from your rig’s tank. Motorhomes store water in built-in tanks, which are usually located at the base of the motorhome or trailer. There are three types of tanks in your unit. A tank for fresh, gray (or used), and black (or waste) water. The pump allows you to draw water from faucets in the kitchen and bathroom and maintain flow in the shower and toilet. Most RV water pumps are small and run on a battery-powered RV battery. (This usually means 12-volt water pumps).
Task #2
The second task of a water pump on wheels is to deliver a certain amount of water per minute. Trailers or campers can use pumps that produce 3.5 gallons of water per minute. Larger motorhomes may use pumps that produce 5.3 or more gallons per minute. Gallons of water per minute equates to pressure per square inch, or pounds per square inch. When your unit is connected to the city water line, it will often bypass the RV water pump because the city water is already pressurized.
What is the Best RV Water Pump?
Note that in a recreational vehicle each square inch of available space should be utilized.
We decided that the best RV water pump must be easy to install or replace and function silently. It must have a powerful and thermal protected motor. Also, we discovered that electricity and water consumption depends on motor power, so it’s important to buy suitable for your aim water pump.
