Most homes with a basement will have at least a sump pump, with many also having an ejector pump. Although these pumps are similar, they have very different purposes. As a homeowner, it is important to understand the difference so that when something goes wrong with either pump, you have an easier time troubleshooting and finding a solution to the problem.
Sump Pumps
Sump pumps are used in many homes to keep ground water that surrounds the home’s foundation out of the basement. Typically a sump pump is in a cylindrical-shaped enclosure in the floor, called the sump basin, which is connected to the drain tile system. Ground water collects in the sump basin until the level of water triggers the sump pump’s float device. Once the float is triggered, the sump pump is activated and pumps the excess water up into the discharge pipe. This will direct the water into the sewer, septic or drain field away from the house’s foundation.
Ejector Pumps
Like sump sumps, ejector pumps push excess water out of the basement. However, instead of ground water, ejector pumps will collect and pump gray water from basement drains and water appliances or fixtures. These are typically found in homes with partially or fully finished basements which have a washer, utility sink or floor drain.
Since the water in sump pumps is usually clear ground water, it is rarely the source of the distinct smell of sewer or wastewater. While a flooding basement is often the first sign of a sump pump gone bad, a sewer odor in your basement may be an ejector pump problem. Either way, your local sewer or septic professional is the first call you should make to get the issue resolved.
