A Guide to Buying the Best Battery Backup Sump Pump

There are some homes that have basements or spaces that have some sort of protection in place to keep groundwater damage from occurring. Generally, what this would be is some sort of tube network within the foundation.

The tubes direct water into a sump or a pit that is shallow. A sump is used for the purpose of pushing water out and away from your home through a pipe.

Sump pumps are automatic in operation and dispose of water regularly without any need to manually start it, which means that there is no need to maintenance them as they operate.

However, you want to still check on your pump about every 4-6 months to ensure it is not broken or damaged because if it is, it causes your basement to flood.

By shopping around for the best battery backup sump pump, you can be sure you will stay prepared in case your old pump becomes damaged or dies out on you.

The Different Types of Sump Pumps

When it comes to sump pumps, you will either have a pedestal sump pump or a submersible sump pump, as these are the two different types that are available on the market. Let’s now take a look at what each of these two types of sump pumps is able to do:

Pedestal pump

In a pedestal sump pump, the motor is located on the shaft that is above the sump (out of the water). This is the cheap sump pump type (they tend to cost less than the submersible option). The reason that they tend to be cheaper is because they aren’t cooled by the water that is in the sump, which makes them a greater risk of overheating from extreme use.

Submersible pump

Pumps that are submersible are located at the bottom of the sump, and they are usually surrounded by water. One thing that you should keep in mind is that when you get ready to replace the pump that you currently have with a new one, make sure that the HP is the same as the previous pump that was installed.

Sump Pump Tip

Keep in mind that whatever sump pump you choose, it will need to run with clean groundwater only; the water should not be dirty. You should never channel any water from a washing machine or from a water softener. The reason being is because it could damage or shorten the life of your sump pump. You should also never utilize any sump pump for a fountain or a pond.

Sump Pump Features to Take Into Consideration


There are three different types of switches that are utilized by a sump pump; those would be:

  • Tethered float
  • Vertical float
  • Electronic float

These all turn on automatically when the water reaches a certain level inside the sump pump.


With all of the different types of sump pumps that are available to purchase, you will notice that the horsepower on different models will vary. The horsepower options that you can expect to see available include:

  • 1/4 HP
  • 1/3 HP
  • 1/2 HP
  • 3/4 HP
  • 1 HP

While the horsepower plays an important role in your sump pump’s operation, what you should really take note of is the gallons of water the pump can pump out per hour. If your sump pump will be running regardless of the weather conditions, then you should make sure that you purchase a sump pump that will operate powerfully regardless of how harsh the elements are.


Your sump pump of choice will have either a metal or plastic housing. The sump pump price tends to go up when they are made from stainless steel.

Emergency Sump Pumps – For Backup

The pumps above that were mentioned are pumps that require an electrical current from your household in order to operate properly. In this case, you might be wondering what happens to your pump whenever a big storm hits and cuts the electricity out. Well, this is when your emergency battery sump pump will take over. There is a battery that stays charged continuously that is linked up with the discharge pipeline. You will have hours of protection with this backup pump when your current one is out. There are even some backup pumps that have a feature which alerts you when the unit needs to be replaced. These would be Hybrid models, which are considered to have the best battery backup pump options available. These models generally combine your regular pump with a battery pump when needed.

Quality Sump Pump Accessories and Features

Check Valve

The check valve is basically a flap that keeps water inside the pipe from going back into the pit once the pump turns off. Regardless of whether or not your system has a check valve, you should still always replace it if you will be buying a new sump pump in case of mineral build-up from the water has caused corrosion because this interferes with the operation of the flap.

Sump Cover

If your sump pump didn’t come with a watertight cover, then it is a good idea that you go ahead and add one now. The reason that you’ll want to add one is because if it is exposed to the elements, debris can build up inside it, which would allow radon to enter the basement.

Now that we have info on sump pumps covered let’s take a closer look at some of the best battery backup sump pump options available right now to purchase.
