best sump pump with battery backup

Sump pumps are a necessity for any home or commercial building. They are used to prevent flooding in basements and crawl spaces, as well as provide a continuous flow of water to prevent the accumulation of dirt and debris that could clog the sump system. But it’s also important to ensure they are functioning properly at all times. They are designed to automatically remove water from your basement when it floods.

But what happens when the power goes out? Battery backup systems will run your pump for several hours if there is a power outage. This is ideal because even if your power supply goes out, your sump pump will continue to work for a while.

If your sump pump fails or has a battery that’s about to die, you’re going to have a very bad time. That’s why we went and did the research and compiled a list of the best sump pumps with battery backup available today.



Buying Guide

Sump pumps are important equipment to have in your home, especially when you have kids or pets. They keep your basement floor dry and prevent water damage from getting into your house. However, it’s very important to choose the right type of sump pump, and also have a backup power supply. In order to choose the best sump pump for you, consider the following:

Sump pump size

The first thing to look at is the size of your sump pump, as you will need enough space for the pipes and pump. Sump pumps come in different sizes, ranging from tiny to large. You can choose from a number of options, such as the 2.5 Gallon (3.5 L), the 4.5 Gallon (18 L), and even the 10 Gallon (36 L) ones.

Pump style

Another factor to take into consideration is the style of the sump pump. You have a choice of vertical, horizontal, and even submersible pumps. These pumps are also designed for various purposes, like cleaning up sediment or silt from your sump pit or draining water.

Sump Capacity and Flow Rate

One of the most important factors to consider when selecting a sump pump is the capacity. A larger capacity means that you can handle larger amounts of water, and a larger flow rate, which is important if you are using your sump pump for a long time.

A higher capacity also means that it will be able to deal with a heavier rainstorm, and will be able to pump more water out of your basement in a short period of time.

If you don’t know how much rainwater your home receives on average, then you can get an estimate from your local utility company.


When choosing a water-resistant pump, there are several things to consider.

  • First, how long does the pump last?
  • Second, how easy is it to install?
  • Third, how safe is it to use?

These are the questions you need to answer before you buy a waterproof pump.

The life of a pump is directly proportional to the amount of pressure it exerts, so if you need to keep your basement dry for only a couple of months, then a low-pressure pump is likely to be adequate. If you want to keep your basement dry for years on end, then you may need to invest in a high-pressure pump.

Lastly, if you do get your pump leaking at some point, then make sure you have a way to fix it quickly. It’s always better to have a backup system than to wait for an emergency and end up having to replace the whole pump.


Your sump pump should be made of a corrosion-resistant material that can withstand long periods of use in the basement.

It’s also important to consider what material your sump pump is made of. If it’s made of plastic, it won’t last as long as one made of stainless steel. The metal sump pumps also work better in extreme conditions and are more resistant to corrosion.

Pressure Gauge

A pressure gauge is an essential part of any sump pump since it helps to monitor the water levels in your sump and make sure that the system isn’t being overworked by the pumps.

The best sump pumps have a digital pressure gauge, which will show you the pressure in your sump and allow you to adjust accordingly. This means you can keep your sump safe from flooding and overflowing. It will also be easier to find a replacement pump if anything goes wrong.

Battery Type and Capacity

Battery capacity is perhaps the most important aspect of any sump pump. The bigger the battery the longer the pump can run on a single charge. So, consider the size of your house, and the number of rooms you want the pump to protect. You’ll also need to figure out how often you expect to have water flooding your basement.

This will help you decide which battery you should get. It may be worth it to buy a rechargeable battery to power the pump.

The best batteries are Lithium-ion (Li-Ion) or Nickel Cadmium (NiCd). They have a higher capacity, more durability, and less of a risk of overheating and shorting out.

Power Consumption

When choosing a power source for your sump pump, there are two main considerations:

  1. How much electricity does your current system use?
  2. How often will your sump pump run?

The first consideration is a simple matter of how much electricity your system uses. When determining this, you should consider the type of pump you have (which could include both electric and battery-powered pumps), and the size of the sump pit in which it will be installed.

If your current system uses 2 amps of power at 24 volts, and you’re looking for a backup system, you can easily find a 12-volt battery that is capable of supplying 5 amps of current, which is equivalent to an hour’s worth of power.

However, you should always consider the cost of your system, as well as how often you will need to use it. If you’re planning on using the backup system very rarely, or if you already have a backup system in place, then the cost and electricity usage may not be a factor for you.

Water Level Indicator

The water level indicator helps you keep track of your sump pump’s output, and it can save you a lot of trouble if it starts to fail. The good news is that there are lots of different types of water level indicators available on the market today.

Noise Level

You can find sump pumps that are very quiet or loud. It’s all about personal preference and what you’re looking for. A quiet sump pump doesn’t make much noise, but you’ll be able to hear everything clearly. The loud ones can be quite loud, but they also work well.

Noise levels vary from one model to another, but you can use the noise level guide in the table below to compare.


Are sump pump battery backup worth it?

Sump pumps are very important safety devices. They allow you to drain the water from your basement quickly when it floods so that you can prevent a lot of damage to your house. And when they’re backed up with a battery, they provide a backup in case of an emergency, such as an earthquake or a power outage. But they can also be an added expense for your home if you install them and forget about them.

Since they’re not required in all homes, you don’t need to buy them, unless you want to protect your family from flooding and other disasters. And while they may save you money in the long run, they can add significant costs to your home if you use them improperly.

How long does battery backup last on the sump pump?

Batteries used in sump pumps will typically last from 2 to 5 years. It depends on the capacity of the battery, the use it makes, and how often you recharge it. Make sure that the battery you’re using is compatible with your sump pump, and that the sump pump has enough power to charge it.

Which is better for a home: a sump pump with a battery backup or one without?

Generally, a home with a sump pump that has a battery backup is a better option than one with no battery backup. A sump pump with a battery backup provides an instant backup if the power goes out, so it can help you save your home in case of an emergency.

What is the difference between a sump pump and a submersible pump?

A sump pump pumps water out of a flooded basement or other underground structure, while a submersible pump is a special type of pump that is submerged in a liquid. Both are used to pump water out of structures, but the main difference is that the sump pump is connected to a drainage system or a foundation drain, while the submersible pump is designed to be self-contained and run on its own power source.

Is it better to install a sump pump on a concrete slab or a dirt floor?

The best option would be to install a sump pump on a dirt floor. The reason is that when a sump pump is installed on a concrete slab, the water tends to flow into the ground, and the pressure from the pump does not increase as much. This can cause flooding in your basement, and also make it difficult to drain water from the area.

How often should a sump pump be cleaned?

The best way to clean a sump pump is by draining it completely and then cleaning it thoroughly. You should also remove all debris, dirt, and corrosion that may have accumulated over time, and then change the filter regularly.


You may have heard the saying, “sink or swim.” This means that if you’re not prepared, you might sink, or you might drown. This is especially true if you live in a flood zone.

That’s why you need to invest in a sump pump with battery backup. If the power goes out, your water will still drain from your basement. And if you have a sump pump with battery backup, you can be sure that it’ll still keep your home safe in an emergency.

And to make sure that your battery backup keeps working, we recommend the best sump pump with battery backup. It’s a great combination of a powerful pump and a long-lasting battery. You’ll get everything you need to keep your home safe and your basement dry.
