Sump pumps are important tools in the fight against water damage. Although these pumps are simple to maintain, many homeowners don’t know what size pump they need. Everyone has different needs, for instance, some might live in an area that is particularly dry, or in homes where the foundation is below the water table. Sump pumps aren’t chosen based on the size of your home, but chosen based on the amount of moisture it will have to deal with. Size isn’t the determining factor when choosing a pump, look for the amount of horsepower the motor has. The strength of the motor, not the size of it, determines how powerful the pump is, and should be what you look for.

The power of a sump pump’s motor is measured in horsepower, and are usually sold in increments out of 1, such as 1/2 horsepower, or 1/3 horsepower. 1/3 Horsepower pumps are standard, meaning if your home had a pump installed before you bought it, its most likely this pump.

A 1/2 horsepower sump pump is capable of removing at least 3,000 gallons of water per hour. Its one of the most powerful motors and widely available. Although you can find pumps that are even stronger, there is rarely a need, especially for the average homeowner. If you still have drainage problems when using a pump this powerful, then the pump pit is most likely to blame, and not the pump.

The final common type of sump pump is the 1/4 horsepower sump pump. This will be a great deal weaker than a 1/2 horsepower pump, and just a bit weaker than the 1/3 pump. Although problems with a pump being too strong are rare, a 1/4 horsepower pump is perfect for homeowners on a budget who don’t think a larger pump is necessary.

How much horsepower you’ll need is based on several factors, for instance, how much of your drainage system is connected to the pump? How deep is the groundwater near your home? How deep is your basement? If the foundation of your home is below the water table, you’ll require a much stronger pump than the homeowner whose foundation is above the water table.
