Choosing the right sump pump for your house

The right sump pump for your basement is directly related to how much water has to be moved.
More water means a larger pump is needed.


In general, larger pumps are also designed to work longer and harder than smaller units. They are built to handle a heavier load than smaller pumps. In any case, maintenance is a requirement to make sure the pump stays in operating order.

Pumps are generally 1/4, 1/3 and 1/2 horsepower. The half-horsepower pump is used on the largest basements that are below the water level. Water infiltration is a continual problem. This size will move the most water in the least amount of time. It also draws the most power during operation.

The 1/3 horsepower motor can be used for basements with water in the sump regularly, but it is not going to move as much water as the half-horsepower model. This size is best suited for basements at or near the water level.

The quarter-horsepower motor is the weakest of the three and moves the least amount of water. These should be used in areas where sump water is not a regular event and the basement is above the water table. This unit uses the least amount of power.
