Guide to Buying the Best RV Water Pump

camper water pump

A water pump seems like a simple piece of equipment, but it is invaluable when traveling. There are several situations that force travelers to use such a pump. In addition to trivial daily hygiene (taking a shower, visiting a portable toilet stall), washing clothes, and cooking, there are a number of other situations.

For example, using a water RV pump will be relevant when filling the tank with freshwater, when emptying it, in the process of parking (without the possibility of connecting to the water supply network). Also,travel trailer water pumps will be real salvation in moments when all the water sources available possess low pressure.

Can you leave the water pump on in RV?

Should you leave the 12 Volt water pump for RV operating, or do you need to shut it off? The question of the permissibility of continuing to operate the pump while it is not purposefully used to this day remains open. RV travel fans are divided into two groups. The first believes, that the 12 Volt RV water pump can be left on, even when temporarily not in the mobile home. Others, on the contrary, insist on turning off such equipment. What are the reasons for the former and the latter? In principle, you can leave your water pump running since most models provide this format of operation. On the contrary, this way, you are more likely to know about its accidental failure.

 

But on the other hand, you should not forget about the risks of leaks and their unpleasant consequences (RV flooding). In short, when selecting the best water RV pump, always weigh the pros and cons. Another nuance in planning to turn the pump off whenever you’re not using it (outside the RV) can be the seeming energy savings. But in reality, such appliances use negligible amounts of energy during idle periods, so you’re unlikely to save too much money. Those who always turn off the water pump also attribute it to the noise it makes. For example, many families are sensitive to any sound and therefore prefer to turn off all appliances, including water pumps, at night.

How long can an RV water pump run?

When planning to use a water pump during traveling and living in an RV, you will definitely wonder about the allowable duration of its operation. In fact, such equipment is designed initially to work on demand. If the water pressure drops, the water pump will automatically start (to compensate). Modern RV water tanks and pumps make life much easier when traveling on the road. These products, by their design and purpose, are used intermittently. They never work all the time without stopping, even if the crane will be in the open position for a long time.


As long as the 12V water pump RV operates, you can safely do all household tasks such as washing, dishwashing, and showering. Remember also that this equipment draws the available water supply from the tank as it operates.

How much power does an RV water pump use?

Depending on the manufacturer and concrete model, the RV water pump may consume different power quantities. You may meet several variants – 110 and 12 Volt water pump for RV solutions. The greater the power consumption, the higher the power and performance of a particular device. The amount of power consumption is traditionally measured in amperes. Small, compact, modern RV pumps draw relatively little power, approximately 5 to 15 amps. A 5 Amps (12 Volt) device consumes approximately 60 watts. You will undoubtedly be pleased with the fact that fresh water pumps for RV do not work all the time. Usually, they function cyclically (a couple of minutes working, then a couple of minutes resting).

How does a 12 Volt RV water pump work?

The main purpose of any water pump, including those designed for RV, is to pump water from the reservoir through the arranged pipeline to the shower, toilet, sink, and other water withdrawal points. How does this equipment work? The device is operated by electricity (it is switched directly on the RV wall). Many models of RV water pumps are equipped with a pressure relay, which can control the water pressure. Also, this relay is responsible for automatic switching on of the pump at the moment of water pressure fall.


Similarly, this relay can switch off the pump when the water pressure is stable (can be set individually). The RV water pump fittings’ quality affects the stability and longevity of the pump. All fasteners and gaskets in this equipment must be durable and wear-resistant to protect the unit from leaks. As the pump operates, it can detect a drop in water pressure and automatically start and draw water from the available reservoir. This kind of fresh water pump for RV can be used as the primary water resource or applied when you need a reserve of clean water for domestic needs. This is especially true in cases where there is no possibility to use external water sources. If you are pursuing saving water supplies, experts advise you to turn off the device. At least do not turn it on until you need it again.


Another alternative use of the water pump is to use it as a backup water system. If the water pressure drops, the device will instantly turn on and deliver more water (it will take it from your reserves).


Another question sounds like this – why is it meaningful to prime RV water pump? The fact is that water pressure is a variable unit. It can fall as well as rise. Significantly often, the loss of pressure is fixed at moments when you do not use the device for a long time. Downtime causes minor and major breakdowns. Therefore, to regain the former stable pressure, it is necessary to pressurize it. This is what the priming procedure is for.

Does the RV water pump have a filter?

Inexperienced purchasers often ask this question. First, be sure, the vast majority of camper trailer water pump devices are added with filters. They can be removable and non-removable. A removable RV water pump filter, as understood from the name, can be periodically removed and cleaned of dirt buildup. How often should this part be cleaned? It all depends on the frequency and intensity of the device’s use. You should not wait for problems in the operation of the filter or the appearance of suspended matter in the pumped water. It is better to clean the filter once or twice a month. With less regular use, it is acceptable to perform this procedure even less frequently. Built-in RV water pump strainer is easy to remove, clean, and put back in place. In the second case, it is a non-removable 110v RV water pump. There is no way to clean it and keep it functional. Such filters’ operation involves replacing them with brand new devices (available for sale in most plumbing supply stores).


The filter is an indispensable RV water pump accessoire that allows you to solve two problems simultaneously. The first is to protect the mechanisms of the pump, and the second is to keep the water clean enough for domestic usage. Some filters can be used strictly for freshwater, while others can be applied for both fresh and saltwater. So always consider this parameter before buying an RV filter. In addition, some pumps are purchased for use on marine vessels, so its mechanisms must be ready to face aggressive saltwater.


A dirty filter can adversely affect the quality of pumped water and the functionality of the unit. If you are going to clean the filter, it is advisable to read the manufacturer’s recommendations. The standard procedure involves several steps. These are disconnecting the device from the power supply, housing unscrewing, thorough filter components cleaning, housing assembly, starting the device.
