Below-Grade Plumbing
Sewage Ejector Pumps in Ellicott City, MD
A basement bathroom or utility sink sits below the sewer line, so gravity will not do the work. The ejector pump does, and it has to be sealed and sized correctly.
Sized and sealed right
We size the pump to the fixtures it serves and make sure the basin is properly sealed and vented.

How the Pump Works
Moving Waste Uphill
Through most of a house, gravity carries wastewater out through the drains. A bathroom or utility sink in the basement sits below the sewer connection, so its waste runs into a sealed basin instead.
When the basin fills to a set point, a float starts the pump and it forces the waste up a discharge pipe to the main line. A check valve prevents backflow once the cycle ends, and a vent manages pressure and lets sewer gases escape.
An ejector is not a sump pump. A sump pump moves rainwater and groundwater away from the foundation; an ejector is built to handle the solids in toilet and shower waste. Connecting the two systems improperly causes sanitation and odor problems.

What We Handle
Repair and Installation
Diagnosis
A pump that runs but moves nothing may have a failed motor, a clogged intake, or a bad check valve. We check the electrical, the sewer line, the lid seal, and the pump itself rather than swapping parts on a hunch.
Repair
Often it is a blockage to clear, a switch or valve to replace, or a loose connection to make good. Those are straightforward fixes when they are caught before the basin overflows.
New Install
A new unit has to be sized to the fixtures it serves, with the pumping height, discharge distance, and local code all accounted for. The basin seal is what keeps the room usable.
Stop Using the Fixtures
Signs the Ejector Pump Is Failing
If the pump has given out, stop using the basement plumbing. Once the basin overfills, wastewater comes into the house, and that is a different and much more expensive problem.

What to Expect
How the Visit Works
Step 1
Inspect the system
We check the electrical supply, the lid seal, the vent, the check valve, the discharge line, and the pump, because any one of them can produce the same symptom.
Step 2
Repair or replace
You get an honest read on whether the existing pump is worth fixing. Age, condition, and the cost of the repair all go into that answer.
Step 3
Seal and test
We reseal the basin, cycle the pump, and confirm waste is moving and the vent is doing its job before we call it finished.

Ejector Pump Questions
What is the difference between an ejector pump and a sump pump?
A sump pump removes rainwater and groundwater from around the foundation. An ejector pump handles sewage from fixtures below the sewer line, including solids. They serve different purposes and should never be cross-connected.
Why is there a sewer smell near the basin?
Usually a failed lid seal or a vent problem. The basin is sealed and vented for a reason: to contain sewer gases and manage pressure during the pump cycle. Both are repairable and worth doing promptly.
My pump runs but nothing drains. What is wrong?
Commonly a clogged intake, a failed check valve letting the waste run straight back, or a motor that has lost its ability to lift. Stop using the basement fixtures and have it looked at before the basin overfills.
Should an ejector pump have a battery backup?
Backups are more common on sump pumps, but for a finished basement that depends on an ejector, it is a sensible consideration. If the power goes out, so does your ability to use the fixtures down there.
Does a new ejector installation need a permit?
Sizing, discharge routing, and venting all have to meet Howard County code, and the work is inspected. We handle the permitting as part of the installation.
