What Size Basement Pump Do I Need for My Home?

Heavy rain can cause flooding, which can cause pretty serious damage in your basement, if you haven’t prepared properly for it. The best way to do this is through the use of a sump pump, especially if you live in an area that experiences flooding and heavy rains. Essentially, the sump pump makes sure that water stays out of your basement, keeping it piped away from your home’s foundation. This keeps your basement dry and free of the damage that comes along with flooding. The key, however, is having the right size sump pump. Here’s how to determine what size you need for your sump pump.

What Size Basement Pump Do I Need for My Home

Capacity

The first thing you’ll want to do is estimate the capacity of your sump pump. On a rainy day, run the pump until the water drops to the shutoff level. Unplug the pump, and leave it off for one minute. While the pump is off, measure how high the water rises in the sump pit during that time. Typically, a sump pit will take in around 20 gallons (20 inches) of water in one minute. Take the number of inches the water rose by, and multiply it by 60. That formula will allow you to estimate how much water you’re taking in over the course of an hour. Using the number you come up with, multiply it by 1.5. That will build in a safety factor for your pump’s capacity. 

Power

How strong your sump pump’s motor is will determine how powerful it is. There are several options when it comes to horsepower. The standard option is .33-horsepower, but there are other options, as well. Less or more power is available through the .25-hp (¼ hp), the .05 hp (½ hp)-hp and the ¾ hp. In areas where rain is heavier and flooding occurs more often, the .5-hp or ¾ hp pump might work the best. These pumps can take out  3,000 gallons of water or more per hour. If you don’t need a larger sump pump, the .25-hp motor should work well. Keep in mind that this information should be available right on the packaging of the pump, so make sure to check it out before you purchase. 

Other Thoughts

The estimate you come up with, and choosing the right motor size will definitely put you in a good position when considering a new pump. However, there are some other things to think about, as well. For instance, if you have a wider sump pit, the estimate may be off a bit. It’s also important to take a look at the height the water has to travel in order to be discharged through the discharge pipe. This is called the vertical lift, or static head. The longer the distance the water has to travel, the harder the pump will have to work.
