The sump pump is used to remove the water that gathers in the water-collecting sump basin. If you have this type of basin in the basement, you know how important it is to install a sump pump, ensuring a flood will not occur in the basement by using it. But traditional pumps fail when the power goes out due to heavy storms or other reasons, meaning that until the power comes back, they do not work, and the possibility of a flood becomes imminent. This is where the battery back up pumps shine as they switch to using the power provided by the battery in case of a power failure, thus the possibility of a flood not existing regardless of the circumstances. To find out what are the best sump pumps which come with battery back up on the market at the moment, check out the comparison table below.

The sump pump has the role of removing the water that accumulates in the sump basin which is usually found in basements. There are a lot of situations that lead to the accumulation of dangerous water levels in this basin, the most common being drains of the waterproofing system in the basement, water that funnels into the basin, or even because of rain and natural groundwater in case the basement is situated below the water table level. Thus, it is easy to understand the importance of the sump pump as it prevents a disastrous flood from occurring.
Seeing just how important this product is, it was inevitable for variations to appear. This is where battery back up sump pumps come in, these more effective models being the preferred choice of modern people as they actually offer a continuous operation, unlike sump pumps which solely rely on receiving power to operate, pumps that will inevitably fail you in the case of a power outage. On the market for sump pumps which feature battery backup, there are two main types of models you will encounter, more precisely DC and AC/DC sump pumps.
When the AC power is out, the battery backup system is going to switch to DC battery power, thus ensuring the possibility of a flood will not occur. While the power is on, the sump pump will automatically use the AC wall current to not deplete the battery uselessly. When making this purchase, another aspect you must consider is the type of battery the sump system is compatible with. Most commonly, deep cycle batteries and lead-acid batteries are used in these systems, but this is something you can easily check by looking at the spec sheet of the product.
What you need to keep in mind is the fact that this is an investment you must make if you want to spare yourself of the hassle involved with a potential flood, the backup sump pump system guaranteeing that the basement and all the belongings you place in it will not ever fall victim to this dreaded occurrence.
There is another type of sump pump that some people use, more precisely the water-powered type. Unlike water-powered sump pumps, battery backup systems do not rely on the water supply to work, which is a good thing considering the fact that if they were to rely on it, their operation would be drastically limited. Thus, this type of system has the major advantage that it is not reliant on any exterior factor as it works through AC or DC current.
Another major strong point of battery backup systems is the fact that they are easy to install, a professional installation not being necessary with them. All you have to do is to connect the sump pump to an existing discharge pipe or to a separate pipe, and you are done with this procedure, being able to enjoy the new addition you have made. A lot of money is saved due to this simple installation as calling in a professional can cost a few hundreds of dollars.
In the case of a power outage, the main advantage of the system shines as the sump pump continues to operate by relying on the power provided by the battery. Therefore, the possibility of a flood occurring is basically impossible. Of course, this operation is not unlimited as the battery will be able to provide power for a limited period of time. But if the model that you invest in is capable of running for up to 26 hours when the battery is used, like the Wayne WSM3300 is capable to do, for example, there probably won’t exist the situation in which the power will not come back until the battery is completely depleted of power.
If you make sure to invest in a high-quality sump pump like the ones featured in our top, you will get to enjoy an excellent pumping power as well. Quality products of this kind shown deliver a flow rate of up to 3000 gallons per hour or more at 10 feet of head, thus ensuring the pump is perfectly able to handle the incoming flow of water without a problem.
Another main advantage of making this investment is the fact that it is basically a necessity for most home, probably even yours. After all, you do not want to face the costs of draining the water out of the basement or to be forced to replace certain valuables you keep in this area of the house because they have been destroyed by water. Thus, the installation of a backup system is not optional for most as it is rather mandatory.
A backup sump pump can either boast a plastic construction, a cast iron construction, or a stainless steel and cast iron construction. Each type of construction comes with its own set of advantages, so it is more of a personal preference when it comes to choosing the pump from this point of view.
The models which feature a plastic construction are usually less expensive and they are preferred by many as they are quite durable and corrosion resistant. These sump pumps are ideal when a lower performance is required or when you simply do not have the budget for a more expensive option. The systems that boast a cast iron construction have a more increased weight and the heat distribution is far superior. It is the added weight that allows them to stay inside the basin without moving an inch. Also, the density of this material is what offers its superior heat distribution and that helps the motor run cooler, thus increasing the life of the pump.
The third kind, more precisely sump pumps made with stainless steel and cast iron, are corrosion-resistant, they offer an excellent heat distribution, they boast a superior performance, and are heavy enough to stay at the bottom of the basin without moving. This construction is definitely the best to go with, but the prices for these pumps is higher so they do not always fit people’s budget.
What you definitely need from the sump pump is for the operation to be as simple as possible. This is why we recommend you invest in a model with an automatic operation, more precisely one that automatically switches to using the battery power when a power outage occurs. It is an important element to take into consideration as you might not always be at home when the power goes out, thus not being capable of switching from AC to DC yourself.
It is important for the model you invest in to be fully submersible, featuring a submersible tethered float switch as the simple design allows an easier use of the sump pump. Also, the tethered float switch allows a more complex adjustability, providing a superior pumping range for turning the device on or off. As you can see, all the models that are featured in our top are fully submersible, so any of them makes for a great choice to go with from this point of view.
Another important element to look into is in what situations the backup sump pump sends off audible alarms. Considering the fact that the sump pump is installed in the basement, it is not convenient for you to have to go down and check it once every few hours to see if everything is alright. This is where the alarms shine as they will announce you when it is time to check the sump pump as something has happened. When you are shopping for this type of product, make sure it sends off alarms in as many situations as possible, the most important being when the battery has been depleted of power and when the water level is high.
On every market, there are a few companies that manufacture better quality products than others. When it comes to backup sump pump systems, the three major brands it is recommended for you to purchase from are Wayne Pumps, Zoeller, and Superior Pump. In the following, we will talk about each of these companies so that you know a little more about them and what they have to offer, better understanding by the end of this piece why they are the market leaders.
Wayne Pumps is the company that probably releases the most high-end products on this market, this being easy to see once you check out our ranking of the best back up sump pump systems, a ranking where no less than 3 models produced by this brand appear. In addition to designing and producing sump pumps, the company also produces pool pumps, well pumps, utility pumps, sewage pumps, lawn pumps, and effluent pumps. Thus, it is a company which has gained a wide recognition as it not only produces high-end pumps but because it covers a big part of the pump market as well.
The Zoeller brand is another name that you will stumble upon often when searching for backup sump pump systems as the dedication and passion the company puts into designing and manufacturing each and every product has made it a customer favorite worldwide. Being one of the most respected and renowned companies on the market, the principles and values it takes into account when creating the much-needed sump pumps are quality, durability, and reliability. Thus, a product bought from this company is surely a long-lasting investment that will be by your side for a long time, not failing you even after years of continuous use.
What has made Superior Pump become one of the biggest brands at the moment is the fact that this once small family-owned business has never strayed from its principles, trying to innovate the sump pump market with each product released and always paying attention to the quality of the products offered to customers. The hard-working employees at this company focus on even the smallest details when manufacturing the pumps, ensuring the products they release are of an impressive durability in order to not fail loyal customers who rely on the pumps to prevent floods from occurring.
The construction of the backup sump pump system is the first indicator of its durability. As you can see, there is a variety from this point of view when it comes to the models that we chose as being the best. Of course, this variety when it comes to the products that are used for the construction of the pumps also separates them when it comes to their durability, some models being superior to others. When it came to this rating criterion, the Zoeller 508-0006 Aquanot 508 ProPack53 received the biggest rating due to its impressive and strong non-corrosive cast iron construction.
For a sump pump with battery backup to be as convenient to use as possible, it must feature a generous battery compatibility as well. As you can see, all the products in our top are compatible with more than a single type of battery, so there is enough versatility from this point of view. When it comes to battery compatibility, the Zoeller 508-0006 Aquanot 508 ProPack53 scored highest again as it is compatible with 27, 29, and 31 group size batteries.
In our top, two kinds of technologies appear, more precisely switch mode and smart charging. The switch mode technology might come with its own set of impressive advantages, but it is inferior to the smart charging technology which makes the entire operation more automatic, going a lot smoother and easier. When it comes to this rating criterion, the model that scored the most points is the Wayne WSM3300 which not only features the impressive smart charging technology but is capable of sending alerts over the phone as well, thus keeping up with the modern times we live in better than most sump pumps do.
One of the most important elements to look into when making this purchase is how long the battery will deliver a continuous power supply to the sump pump. As we are aware of the importance of this aspect, we made sure for the models that are capable of providing the best operational time to receive a higher rating. The three sump pumps that did the best job from this point of view are the three entries which are produced by the Wayne Pumps company, all of them being able to keep the pump running for up to 26 hours in case of a power outage.
The operating temperature of the backup system shows what the favorable conditions for the product’s operation are. Thus, it is an important element to take into consideration when ranking the best sump pumps on the market as you would not want to be stuck with a pretentious product that fails to run when the temperature exceeds 100 degrees Fahrenheit. When it came to this rating criterion, the model that shined the most was definitely the Superior Pump 92900 which can safely operate when the temperature ranges from 32 degrees Fahrenheit to 120 degrees Fahrenheit.
For the product to be of a truly high quality, it must announce you when certain events are taking place, events you need to be aware of in order to ensure a smooth and safe operation of the sump pump. The more the better from this point of view, and as you can see, all of the models featured in our top send off alarms in certain situations. But the one product that shines the most in this department is the Wayne WSM3300 which announces the user when a controller fuse has blown, when the DC pump is in operation when the DC impeller is locked, when the primary pump has any defects, and so on.
LED indicator lights come in handy as they show you how certain processes are developing, making the operation of the battery back up sump pump easier and more convenient. When it came to this rating criterion, the model that stole our hearts and we gave the highest rating to was the Zoeller 508-0006 Aquanot 508 ProPack53 which shows the user when the AC power is being used, when the battery is charged, when the battery is depleted of power, when the battery is charging, when the alarm is muted or turned off, and when the water level is high.
We cannot deny the excellence of the Zoeller 508-0006 Aquanot 508 ProPack53, a sump pump with battery backup that took the market by storm as it can continuously pump the water for up to 7 and a half hours until the battery fully runs out of power. it can withstand operating in harsh environments, which is exactly what you would expect from a qualitative sump pump, not suffering damage in case the temperature goes below 40°F or over 120°F. Furthermore, considering its durable design and impressive performance, we can actually say that it is reasonably priced.
The Wayne WSM3300 is another option worth taking into consideration as it can pump the water for up to 26 hours before the battery is depleted of power. Thus, flooding will not occur as long as you use it. While the Superior Pump 92900 did not rank so high in our top, we must draw some attention to this product as it comes at a very reasonable price, being the most budget-friendly option to go with. It boasts a 23 GPM flow rate at 0 feet head, and the electronic control panel endorses ease of use, so you cannot deny its convenience and excellence in use.
