Ejector Pump Vs Sump Pump: What's the Difference?

Most homes are built so gravity can transport waste to the sewer system. For this to be possible, the home must be higher than the sewer pipes so the waste can drain properly. Sometimes, however, this isn’t possible because of a home’s location or because of plumbing in the basement that reaches deeper than the main sewer lines. In these instances, an ejector pump, sometimes called a sewage pump, is used to force sewage out of the home’s plumbing.

One of the biggest differences between an ejector pump and a sump pump is that an ejector pump has the ability to move solid waste with water pressure.  The ejector pump breaks up solid waste to force it farther down the line and out to the main sewer.  Without an ejector pump, basement bathrooms and any plumbing below the main sewer level would be unable to clear waste. The result would be sewage backing up into the home. 


A sump pump provides a different function than an ejector pump. Sump pumps do not deal with waste or sewage at all. Instead, a sump pump sits in a pit beneath your home. This pit is drainage for excess water that builds up during rainstorms, snowmelt, or flooding of any sort. When excess water accumulates in your sump pit, the sump pump expels the water out through pipes that drain to an exterior location far enough from your home to not cause any issues or backflow. Without a sump pump, basements could be flooded every time it rains. A sump pump ensures that you keep a dry home, even when torrential storms rage outside.

Sump pumps are mostly found in wet climates or where basements are prevalent. They are less common in dry areas or where basements are not popular.

Sump pumps cannot be joined to a sewer line. Instead, they must drain outside. Sump pumps also cannot handle debris. They generally have a screen or grate on the intake so the pump doesn’t suck up anything that could damage and ruin the pump. Sump pumps are meant to transport water only.

While each of these is important in its own right, ejector pumps and sump pumps are different tools that perform very different jobs. Ejector pumps push waste and sewage uphill to remove it from plumbing that’s below the main sewer level. Sump pumps stop your basement from flooding by evacuating water that accumulates from natural sources. If you require one of these pumps but don’t have it, the results could be disastrous.  

In the event you do sustain damage from a failed ejector pump or sump pump, SERVPRO of Milwaukee North is here to help 24/7/365.  Give us a call at 414-354-7566 for a no-cost assessment of your water damage situation.
