What Is an Ejector Pump, and Do You Have One in Your Home?

An ejector pump is in a sealed pit below your basement floor that takes sewage from places in lower level spots like bathrooms, laundry rooms, and any floor drains below the level of your home’s main sewer line. It then pumps the waste upward to reach the main sewer line to remove the sewage normally. 

Without an ejector pump, gravity is just not able to push the sewage up to the main line of your home. If your home has a bathroom in the basement, a laundry room in the basement, a utility sink, or any below-grade feature, there’s a good chance you have an ejector pump system. It is specifically a sewage pump, and it’s completely separate from a sump pump. It also requires a licensed plumber for proper diagnosis, repair, and replacement.

Signs Your Ejector Pump Is Failing

Ejector pump failure has a distinct and unmistakable character — the symptoms go beyond a slow drain and signal that sewage is no longer being pumped away from below-grade fixtures. If you notice any of the following in or near your basement, call a plumber before the situation escalates.

Sewage Odor in the Basement

A constant smell of sewage coming from your basement most likely means the pit is not sealed or not disposing of waste properly. If you’re experiencing this issue, it is a health hazard, and we highly recommend giving us a call immediately to come out and help.

Backed-Up Below-Grade Fixtures

If your toilet in the basement isn’t flushing, or your floor drains are overflowing, your fixtures may be backed up from sewage not leaving your home properly. 


pump alarm indicator

Pump Alarm or Continuous Cycling

Many ejector pumps now include an alarm that goes off when there’s too much sewage and the level rises higher than it’s normally supposed to. If the pump is continuously cycling, which means the pump is constantly running but the level isn’t going down, this indicates a possible failing pump and should be checked out as soon as possible.

overflow indicator

Visible Overflow or Wet Pit Exterior

If there is any moisture or liquid around the pit, or signs of sewage starting to overflow, this is a serious sign that we recommend calling us out immediately. Raw sewage being in your basement is a health hazard, and we need to make sure the problem doesn’t get any worse.

If any of these signs are present, call H2O Plumbing & Sewer Services at (847) 577-8817.

How H2O Diagnoses and Services Ejector Pump Systems

When calling out a plumber for service with your ejector pump, they need to be experienced with this type of system and not just sump pumps. At H2O Plumbing and Sewer Services, we are licensed and have plenty of experience with ejector pumps, and we’re ready to help whenever you need us to. 

Our service process:

  1. Sealed pit inspection — We will open and inspect the lid of the pit, seal condition, and the interior looking for signs of backup, corrosion, or debris.
  2. Float switch testing — The float switch triggers the pump to work when the sewage gets up to a certain level. This is a common issue with ejector pumps, and it could be the reason yours is malfunctioning.
  3. Pump performance assessment — We run the pump to check if there are any specific performance issues we need to be aware of.
  4. Waste-line and vent verification — Proper venting of the sewage is necessary and prevents odors, and that’s why we verify the connection is clear.
  5. Repair or replacement recommendation — After assessing the entire system and looking into all of the options, we will come to you with a recommendation for either a repair or replacement. We will explain why we believe it is the right option, and we will gather your thoughts before beginning any work.
