Best Sump Pump Buying Guide

Best Sump Pump

Apart from all the quality sump pumps listed above, I have also made a buying guide to make the buying decision easier for you. In this buying guide, you can read about everything you need to know before you invest in the best sump pump for your home. That way, it is likely that you make an informed buying decision and end up with a unit that fits your needs.

Sump Pump Types

There are four different types of sump pumps and you should choose one according to your budget and requirements. Moreover, it is crucial that you understand what type of pump will cater to your needs because that last thing you want is to spend a fortune on a sump pump that does not fit your home. The main types of sump pumps are standard sump pumps, sump pumps with battery backup, combination units and sewage sump pumps. Below you can learn more about each type and find out what type fits your needs. Buying the best water detector sensor might also be something you might want to think about if you are dealing with leaks around the house.

Standard Sump Pumps

Best Sump Pump

These types are the standard models and the most common sump pumps. They are designed to pump out the water inside or around your home and prevent water build-up. These units are built to pump out several gallons of water per hour and keep your house dry and secure. Standard sump pumps can be divided further into two sub-categories: pedestal and submersible where pedestal sum pumps have motors outside the water while the submersible units have their motors inside the sump basin.

Sump Pumps with Battery Backup

The sump pumps with battery backup can become extremely handy if there is a power cut in your area. Therefore, during a power outage, the pump will run smoothly and there will be no water build-up around the pump. Many of the battery backup pumps also include an alarm that will notify you by email or text in case of operation failure.

Combination Unit

These types combine the standard pump and a battery pack pump. As mentioned above, with an added battery pump, you will receive an extra layer of protection. The benefit is that you won't have to worry about the performance if there is any power outage in your area. The motor will run efficiently in any situation regardless of the availability of power. In other words, if the standard pump fails, the backup unit will immediately start and continue pumping out water.

Sewage Sump Pump

These are not the conventional sump pumps that most know but they serve the same purpose as other sump pumps. These pumps are designed to pump effluent and sewage waste into a septic system. These units come with more powerful motor than conventional sump pumps because they are designed to move bigger and heavier solid elements that are in sewer water. After installation, they will operate automatically and they can be placed in a separation chamber or within a septic tank.

Features to look for

Best Sump Pump

There are numerous options available to buy and choosing the best one can become a bit overwhelming. The best sump pump is a leak detection pump which will let you know if there is a case of any leakage. There are numerous options available to buy and choosing the best feature can be overwhelming. However, if you are looking for the best sump pump for your home, there are some features that you should know of before you invest your money in a sump pump.


There are many different types of sump pumps on the market and they all come with different switches as well. Your best pick would be a unit that comes with an automatic switch because they are designed to prevent the pump from burning out or fail. In most models, the switch is equipped with an alarm that will notify you if something goes wrong.

Strength (Horsepower)

It goes without saying that more power means higher price. Most low-end units come with a weak motor while all the top-rated sump pumps include a powerful motor. The power of the motor is determined by the horsepower (HP) and it can range anywhere from 1/2 to 1/6 depending on the model.

Capacity (Gallon/Hour, GPH)

Capacity is another integral aspect that you need to consider if you are looking for a quality sump pump and the capacity is measured in GPH (gallon per hour) or GPM (gallon per minute). GPH or GPM measures the efficiency of a pump when it is pumping a vertical distance from the highest discharge point to the bottom. Similarly to HP, the capacity will range between models and you should always compare the HP and capacity between models. Always go for a pump that is powerful enough to handle small solids that can be in the water.


The materials used in sump pumps will determine the price, durability and the performance of the unit. It is wise to look for units that are built of heavy-duty materials such as stainless steel, alloy, cast bronze and cast-iron parts with epoxy coating. The average lifetime of a sump pump is over 10 years and it is never a good idea to try to save a buck or two by buying a unit made of low-quality materials. Buying a sump pump is a long term investment and you should only settle for a durable quality pump.

Power Cord Length

The length of the power cord is important and something that many buyers overlook. It is recommended that you figure out how long power chord you need because it is never a good idea to have extension cords lying around in areas where you are expecting water. These cords come in different lengths ranging from 5-foot to 25-foot.
