What is the Purpose of a Sewage Ejector Pump?

Ejector Pump Repair in Davis

Primarily, sewage ejector pumps are used in homes with basement laundry rooms and bathrooms. Not all home basements require these unique pumps, but when your city's sewer lines running to the street are at a higher level than the fixture, the ejector pump serves to pump all liquids and solids upwards into the sewer line so it can flow correctly. A vent is required for the ejector pump installation to equalize the pressure during any pumping and to provide an escape for all sewer gasses. This vent comes directly out of the sump pit and is either connected to an existing vented soil stack or can go upwards through the roof. The ejector pump has a sealed lid on the basin and a vent pipe for sewer gases. All of these materials are pumped into a sewer line for disposal.

Installing an ejector pump is essential for preventing sewage backups in homes with lower bathroom or laundry fixtures. Moreover, it ensures that wastewater management is handled safely and efficiently, keeping your home clean and hygienic.

People often confuse sump pumps and ejector pumps, and it is easy to see why. They look very similar, and each pump is installed into a pit in your basement flooring. A sewage ejector pump is very similar to a sump pump. Like a sump pump, an ejector pump collects water and any wastewater. If your sump pump handles wastewater, it likely has a sealed lid on the basin and also a vent to allow the sewer gases to escape. These pumps typically have a pipe branching out and leading to a sewer line.

The key difference lies in their functions; while sump pumps primarily handle clean groundwater, ejector pumps are designed to deal with sewage water and solids, ensuring that waste flows away from your home efficiently. This makes ejector pumps essential for homes that require sewage management from below the main sewer line.
