Sewage Ejector Pump
Repair & Replacement
Southern Maryland
Sewage ejector pump failure means sewage backing up into your basement bathroom or laundry room. Deep Dive Plumbing Maryland provides 24/7 ejector pump repair and replacement throughout Calvert County and Anne Arundel County, Maryland.
Basement bathrooms, below-grade laundry rooms, and basement wet bars in Southern Maryland homes all rely on sewage ejector pumps to move waste uphill to the main sewer line. When the pump fails, sewage has nowhere to go. This is a health hazard and a plumbing emergency. We service ejector pumps throughout Chesapeake Beach, Dunkirk, Prince Frederick, Annapolis, Owings, Huntingtown, Deale, North Beach, Edgewater, Davidsonville and surrounding areas.
Ejector Pump Services
Ejector Pump Failure Diagnosis
We test the float switch, impeller, motor, check valve, and basin vent. Most failures are caused by a jammed impeller (wipes or solids), failed float switch, or burned-out motor.
Ejector Pump Replacement
Full ejector pump replacement with a properly sized pump for your basin depth and sewage volume. We install the pump, check valve, float switch, and test the complete system before leaving.
Ejector Basin Installation
New ejector basin installation for basement bathroom additions. We size the basin, install the liner, pump, and vent line, and connect to the main drain line with proper slope and cleanout access.
Impeller Clearing & Cleaning
Wipes, hygiene products, and solids jammed in the impeller are the most common cause of ejector pump failure. We clear the impeller, clean the basin, and test the pump — often restoring function without full replacement.
Check Valve Replacement
A failed check valve allows sewage to flow back into the basin after each pump cycle, causing the pump to run continuously and wear out prematurely. We replace check valves as part of every pump service.
Ejector System Maintenance
Annual ejector pump inspection — float switch test, impeller check, basin cleaning, check valve inspection, vent line check. Recommended every year to prevent unexpected failure.
How a Sewage Ejector System Works
When a toilet, sink, or washing machine below the main sewer line is flushed or drained, waste flows by gravity into a sealed basin (the ejector pit) buried in the basement floor. When the waste level in the basin rises to a set point, the float switch activates the pump, which grinds the solids and pumps the sewage upward through a discharge pipe to the main sewer line.
The basin is sealed with a gasketed lid and vented through the home's plumbing vent stack to prevent sewer gas from entering the basement. A check valve on the discharge line prevents sewage from flowing back into the basin when the pump shuts off.
Every component in this system must function correctly. A failed float switch means the pump never activates. A failed check valve means the pump runs constantly. A jammed impeller means sewage backs up into the basin and eventually overflows onto the basement floor.
Warning Signs Your Ejector Pump Is Failing
- Sewage odor in the basement
- Pump runs constantly or won't shut off
- Pump doesn't activate when toilet is flushed
- Gurgling sounds from basement drains
- Slow draining basement toilet or sink
- Pump makes grinding or rattling noise
- Sewage backing up into basement floor drain
- Pump is more than 10 years old
What Never Goes in an Ejector System
- "Flushable" wipes — they don't break down
- Feminine hygiene products
- Paper towels or napkins
- Cotton balls or swabs
- Dental floss
- Grease or cooking oil
- Medications
Sewage Ejector Pump FAQ
What is a sewage ejector pump and when do I need one?
A sewage ejector pump is required when a bathroom, laundry room, or other plumbing fixture is located below the level of the main sewer line. Gravity cannot move waste uphill, so the ejector pump grinds and pumps sewage up to the main drain line. Basement bathrooms, below-grade laundry rooms, and basement wet bars all require ejector pumps in Southern Maryland homes.
How long do sewage ejector pumps last?
A properly maintained sewage ejector pump typically lasts 7–15 years. Pumps that handle excessive solids, grease, or non-flushable wipes fail much sooner. Annual inspection and testing extends pump life significantly. If your pump is over 10 years old, have it inspected before it fails.
What causes sewage ejector pump failure?
The most common causes are: non-flushable wipes and hygiene products clogging the impeller, grease buildup in the basin, a failed float switch, a worn impeller from abrasive solids, and a failed check valve. We diagnose the cause before recommending repair or replacement.
My ejector pump is making a loud noise — what does that mean?
Grinding or rattling noise indicates something is caught in the impeller — usually a wipe, hygiene product, or small object. Humming without pumping means the motor is running but the impeller is jammed. Both require immediate service to prevent motor burnout.
Can I use a regular sump pump as a sewage ejector pump?
No. A sump pump is designed for clean groundwater only. Sewage ejector pumps are specifically designed to handle solids, have sealed basins with vented lids to contain sewer gas, and use a grinder or macerator to break down solids. Using a sump pump for sewage will destroy the pump and create a health hazard.
What should never go into a sewage ejector system?
Never flush wipes (even "flushable" ones), feminine hygiene products, paper towels, cotton balls, dental floss, or any non-toilet-paper product. These items do not break down and will jam the impeller. Grease should never be poured down any drain connected to an ejector system.
How much does sewage ejector pump installation cost in Maryland?
A sewage ejector pump installation in Maryland typically runs $1,500–$3,500 installed, depending on the basin size, pump capacity, discharge line length, and whether the basin needs to be installed in a new location or an existing basin is being used. We provide a written estimate after assessing your basement layout and discharge requirements.
Does a sewage ejector pump require venting?
Yes — sewage ejector basins must be vented to the outside to prevent sewer gas from entering the living space. The vent pipe runs from the basin lid through the wall or roof to the exterior. Proper venting is required by code and is critical for safety. We install all venting as part of the ejector pump installation.
Can a sewage ejector pump handle a full bathroom?
Yes — a properly sized sewage ejector pump can handle a full bathroom (toilet, shower, sink) plus a laundry connection. We size the pump based on the number of fixtures it will serve and the vertical lift and horizontal distance to the main sewer line. Undersized pumps fail prematurely; we always size for the full load.
How do I know if my ejector pump is failing?
Warning signs include: slow draining in the basement bathroom; gurgling sounds from the basin; sewage odor in the basement; the pump running continuously or not running at all; and sewage backing up into the basement fixtures. If you notice any of these signs, call us immediately — a failed ejector pump can cause a sewage backup in your basement.
