Best Pump For Flooded Basements [Buyers Guide]

Having a flooded basement can be devastating! It not only damages your property but the sooner you get it fixed the better the outcome.  If you are reading this guide, you probably have a flooded basement or at least know someone with a flooded basement looking for a way to get out all that water out and fast!

Once you have a flooded basement, one of the best ways to get water out is using a quality basement pump. This effectively pumps the water out of your basement without any stress on you. However, before going out and buying just any old pump, you need to understand how pumps work – types of basement pumps, what to look for and additional features.

A good basement pump is an important asset which can help save your property from the damages that happen as a result of water. Even for basements not prone to water intrusion and flooding, the basement sump pump can help keep your basement dry and free from mold. Sump pumps can turn on any time water gets to a certain level and begins to pump water outside the house to a place where it does not affect the foundation.


A flooded basement pump or sump pump (as others call it) is effective for taking out water from a flooded basement but it has to be done correctly. If the basement pump is used incorrectly (trying to get out all the water at once) it can damage your building.

When you have a flooded basement, you have water inside your house levelling the water pressure outside your home. If you take the water out too quickly, all internal pressure equalizing that external pressure can damage your foundations.

It is recommended that you take out one foot of water at a time with a 24-hour gap before taking out another foot of water. This way, you take out the inner water pressure without causing any structural damages to your building.

If you are looking to get a good and working sump pump for your basement, we will be taking a look at the basic characteristics of a sump basement pump and some of the best pumps you can buy.

Types of Basement Pumps

The first thing you need to consider when it comes to basement pumps is the different types of pumps. An understanding of the different types of pumps will let you know which is best suited to you and your needs. Let’s take a look:

  • Submersible basement pump: the submersible basement pump is a pump designed to function in the sump basin (located below your basement floor level). This sump has a sensor which is triggered when the water level in the pit rises where it begins to pump the water out of the basement though the connected pipe. If you are considering the submersible basement pump, you should also consider the fact that you will also need to also dig a pit for the pump and this can be an added cost.
  • Battery backup basement pump: the battery backup sump pump is a great choice for flooding specifically because it uses a backup battery for your basement water pumping. When storms hit, it mostly leaves homes without electricity for a while and this makes battery backup basement pumps a great choice. It can pump out up to 100 gallons of water for every single charge and this can work well until the power is restored.
  • Combination basement pump: this is a basement pump which uses a backup battery and electricity for pumping water out of your basement. This is cost effective because it has a dual power source to be used based on your given situation.

Having an idea of the types of pumps is one of the first things you need to know because it greatly affects what you should probably buy. However, there are still some other factors you need to consider to make the best choice. Let’s take a look at some of them:

  • Core material: different types of core materials are used for the production of the exterior and interior parts of these basement pumps. You need to make sure that you have a pump made with durable materials like steel impellers and stainless-steel bodies for better results.
  • Horse Power: most sump pumps have a horse power rating from 1/3 to 1 hp. Depending on the level of flooding, you might need a pump with a higher rating.

Additional Features

  • Switch type
  • Screen intake
  • Power source
