What Should You Keep in Mind When Choosing the Best Sump Pump?

1. There are Different Types of Sump Pumps

When it comes to sump pumps, you will either have a pedestal sump pump or a submersible sump pump. 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 can 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 means a higher 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. Keep in mind is that when you plan to replace the pump that you currently have with a new one, the HP is the same as the previous pump that was installed.

2. Sump Pump is Must Work with Clean Water

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 a water softener as 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.

3. 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 essential 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.


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.

4. Emergency Sump Pumps – For Backup

The pumps above that were mentioned are pumps that require an electrical current from your household to operate correctly.

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 that 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.

5. Quality Sump Pump Accessories and Features

Check Valve

The check valve is a flap that keeps water inside the pipe from going back into the pit once the pump turns off.

You should always replace the check valve if you are going to buy a new sump pump. The reason is that a mineral build-up from the water could have caused corrosion. This can interfere with the operation of the flap, and you surely don’t want that to happen.

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.

You will want to do this because if you leave your sump pump exposed, debris can build up inside of it and create issues you could have easily avoided.


The battery backup sump pumps are priceless tools. When you own one, you don’t have to worry about the safety of your home, even in the worst of weather conditions.

There are countless backup sump pumps on the market, and choosing the best battery backup sump pump can be very frustrating.
