Best Battery Back Up Sump Pump

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 that a flood won’t 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 don’t 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 that come with battery back up on the market at the moment, check out the comparison table below.

Important Details that You Need to Know

The sump pump has the role of removing the water that accumulates in the sump basin that 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 ground water in case the basement is situated below the water table level. Thus, it’s 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 that 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 that feature battery backup, there are two main types of models that 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 that the possibility of a flood won’t 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 that you must consider is the type of battery that the sump system is compatible with. Most commonly, deep cycle batteries and lead acid batteries are used in these systems, but this is something that 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 that 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 that you place in it won’t ever fall victim to this dreaded occurrence.

What Advantages Do Sump Pumps with Battery Back Up Offer?


A sump pump is a necessity in most homes, but is a battery backup system worth the investment? Find out the answer to this question and convince yourself about the importance of buying a battery back up sump pump by reading about the advantages that this type of system offers to homeowners.

  • They Work Regardless of the Water Supply

  • 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 don’t 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’s not reliant on any exterior factor as it works through AC or DC current.

  • Easy to Install

  • 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 that you have to do is to connect the sump pump to an existing discharge pipe or to a separate pipe, and you’re done with this procedure, being able to enjoy the new addition that 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.

  • A Power Outage Doesn’t Affect Their Operation

  • 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 isn’t 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 won’t come back until the battery is completely depleted of power.

  • Excellent Pumping 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 that the pump is perfectly able to handle the incoming flow of water without a problem.

  • Versatility in Use

  • Another main advantage of making this investment is the fact that it’s basically a necessity for most home, probably even yours. After all, you don’t want to face the costs of draining the water out of the basement or to be forced to replace certain valuables that 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.

Guidelines to Make a Good Investment


While there are other additions to the home that definitely take more money out of your pocket, the backup sump pump is quite a considerable investment to make as well, even if it’s a bit cheaper when compared to other types of products. In this section of the article, we will show you what you have to look for when you purchase a battery back up sump pump so that you make a smart and long-lasting investment.

  • Check the Pump Construction Quality

  • 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’s more of a personal preference when it comes to choosing the pump from this point of view. The models that 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 don’t 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’s 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 don’t always fit people’s budget.

  • Look for Automatic Operation

  • What you definitely need from the sump pump is for the operation to be as simple as possible. This is why we recommend that 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’s 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.

  • Invest In a Submersible Model

  • It’s important for the model that 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.

  • In What Situations It Sends Off Alarms

  • 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’s 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’s time to check the sump pump as something has happened. When you’re shopping for this type of product, make sure that 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.
