As you try to look for the right answer to this question, you should know that there is no specific size of the sump pump that is correct for your house. However, one way to get close if you want to know the right sump pump size for basement is explained here.

Choosing a sump pump based on types

Typically, there are two types of sump pumps, which are pedestal and submersible. The former is often simpler to maintain and is fixed above the sump pit while the latter is usually installed inside the hole. This second type is usually correctly fixed and sealed, which makes it sometimes to reach the machine. Also, the pedestal pump comes in numerous models and is a more economical choice than the submersible. However, they both need a long pipe of about 20 feet to connect and water from the basement to the drainage system.

Choices may vary according to unique user needs.

All users have different needs, which influences the size of the sump pump that their house needs and type, among other factors. For instance, some people live in homes built on foundations below the water table while some live mainly dry areas. Therefore, you do not choose a sump pump based on the size of your basement or home. Instead, you chose them based on the amount of moisture it supposed to manage.

Horsepower

One way to pick the right sump pumps is by the horsepower. When choosing the best sump pump, you should instead use the motor’s power than its size. It is the strength of the motor that will determine how powerful the sump pump will be. Most of these pumps are sold according to their motor’s power and not size. Therefore, you can choose the right pump according to the horsepower, which may include 5-horsepower, 25-horsepower, or 33-horsepower, among others.

How do you determine the right horsepower for your home? You can learn the horsepower requirement of your home by the drainage area connected to the sump pump. Most homes would be served well by a 1/3 horsepower sump pump. However, many houses also use 1/2 horsepower sumps since it does not cost so much more. When you use the above mentioned in similar conditions, the 1/2-horsepower sump will pump more water than the 1/3-horsepower sump and even lift it higher than it.

Several factors determine the amount of horsepower you need in your sump pump. First, you need to determine the amount of your drainage system connected to the pumps. Next, you need to understand the depth of the groundwater. Another critical factor is the depth of your basement. Lastly, it would be best if you determined whether your foundation is below the water table or not. If you cannot identify all these on your own, you can invite a technician to help you.

Advantages of Choosing the Right Size

Choosing a sump pump with the most appropriate size for your house comes with numerous advantages. One of the most common benefits is that it will last much longer if it is neither too small nor too large for your house. In other words, it should neither be too overpowering nor too weak for the task at hand. Know the amount of moisture that needs to be pumped and where it will be pumped before choosing the right sump for it. Once you have determined the system capacity and the total dynamic head, you will be able to decide on the correct sump pump for the job.

Final Verdict

By now, you should know the right sump pump size for basement. Most new sump pump models provide a graph or chart on the box or instructions that show the flow against the height of lift for both sizes. They usually give the flow in gallons per minute or gallons per hour. When you multiply the gallons per minute by 60, it is converted to gallons per hour. If the water flows into the sump relatively slowly, you may need a more reliable sump pump than the 1/2-horsepower.
