Sewage Ejector & Grinder Pump Repair: Diagnose Before Replacing
A sewage pump lifts wastewater when gravity cannot carry it to the sewer or septic system. An alarm, a pump that will not start, or a pump that runs continuously needs diagnosis—not an automatic replacement. The cause may involve the float switch, check valve, controls, discharge line or pump itself.
LaVergne's provides complete sewer pump service including sewage ejector pump installation, grinder pump installation, lift station service, pump repair and diagnosis, check valve replacement, float switch adjustment, alarm system installation, basin cleaning, and emergency pump replacement across Bellingham, Mount Vernon, Anacortes, and surrounding Whatcom and Skagit County communities.
Before calling: note the alarm message, affected fixtures and whether the pump is silent, humming or cycling. Share the model number only if you can read it safely without opening the basin. If wastewater is backing up, stop using fixtures that feed the system and request emergency plumbing help.
What to Look for in a Sewer Pump Specialist
Sewer pump work involves wastewater, electrical hazards and a sealed basin. Homeowners should never enter a used pump basin or reach into it. The pump must be sized correctly for the head pressure and volume. The check valve must hold or sewage flows back into the basin. The float switches must be set at the right levels. The discharge pipe must be routed and connected properly. The vent must be open and clear. Electrical supply and protection must follow the pump manufacturer’s instructions and applicable requirements. This is not a job for a general handyman.

Sewer Pump Services
Six sewer pump service areas covering every pump type, component, and situation from new installation through emergency replacement.
Ejector Pump Install
Sewage ejector pump installation for basement bathrooms, laundry rooms, and below-grade fixtures. Properly sized pump, sealed basin, check valve, vent, float switches, alarm, and dedicated electrical circuit.
Install →Grinder Pump Install
Grinder pump installation for properties where the sewer main is higher than the house or requires long-distance pumping. Grinds solids and pumps against high head pressure through small diameter force main.
Install →Pump Repair & Diagnosis
Pump won't start, runs constantly, trips breaker, makes noise, doesn't empty basin, or alarm sounding. We diagnose whether the problem is the pump motor, float switch, check valve, electrical, or clog before recommending repair or replacement.
Diagnose →Pump Replacement
Failed pump removed, basin cleaned, new pump installed with new check valve, float switches verified, alarm tested, and system run-tested through full cycles. We match or upgrade pump size to your system's requirements.
Replace →Check Valve & Float Service
Failed check valve allowing sewage to flow back into the basin after pump shuts off. Stuck or misadjusted float switches causing pump to run constantly or not run at all. We replace valves and adjust or replace floats.
Service →Alarm & Monitoring
High water alarm installation, testing, and repair. Alarms alert you when the pump fails or can't keep up before sewage overflows. We install audible and visual alarms and verify they activate at the correct basin level.
Install →Sewer Pump Failed? Alarm Going Off?
24/7 emergency sewer pump service across Bellingham, Mount Vernon, Anacortes and all surrounding areas.
Most Common Sewer Pump Problems We Solve
Sewer pumps operate in the harshest environment in your home — submerged in sewage, cycling on and off hundreds of times a year, handling solids and debris that clog impellers and jam floats. Components wear out, fail, and need service. Here are the four most common sewer pump problems we diagnose and fix.
We always diagnose before replacing. Many pump failures are caused by a stuck float switch, failed check valve, tripped breaker, or clogged impeller — not a dead pump motor. Diagnosis saves you from replacing a pump that just needs a component fix.
Pump Won't Start
Tripped breaker, failed float switch, burned motor, corroded wiring connection, or tripped thermal overload. We test electrical, floats, and motor to find the exact cause and repair or replace the failed component.
Fix →Pump Runs Constantly
Failed check valve allowing sewage to flow back into the basin, stuck float switch, undersized pump, or a leak in the discharge pipe. The pump cycles endlessly trying to empty a basin that keeps refilling.
Diagnose →Basin Overflowing
Dead pump, stuck float, tripped breaker, or clogged impeller. The basin fills with sewage and overflows onto the basement floor. This is a sewage emergency requiring immediate response.
Emergency →Alarm Sounding
The high water alarm means the basin level has risen above normal — the pump isn't keeping up or has failed. Stop using water immediately and call for service. The alarm is your warning before overflow.

Why Professional Sewer Pump Service Matters
A sewer pump operates in raw sewage. It handles solids, paper, and debris that clog impellers, jam float switches, and corrode components. The check valve must hold against the full column of sewage in the discharge pipe or everything flows back when the pump shuts off. The float switches must activate at the right basin levels. The vent must be open. Electrical supply and protection must match the equipment instructions and applicable requirements. Every component matters.
Licensed plumbers size the pump correctly for the head pressure and volume, install all components to code, test every cycle, set float levels precisely, verify the check valve holds, confirm the alarm works, and ensure the electrical is safe. They diagnose before replacing — because many pump failures are actually component failures that cost a fraction of a new pump.

Sewer Pump Service FAQs
Common sewer pump questions answered by our licensed specialists serving Whatcom and Skagit Counties.
How much does sewer pump replacement cost?
The quote depends on pump type and capacity, basin access, discharge piping, controls, check valve and any required electrical work. Diagnosis can show whether a component repair is enough. Ask for an itemized scope identifying reused and replaced parts, testing and warranty coverage before approving work.
How long do sewer pumps last?
Service life varies by model, operating hours, system sizing and what enters the basin. Age alone does not prove the pump needs replacement. Repeated failures, corrosion, motor damage and the availability of replacement parts help determine whether repair or replacement is practical.
What is the difference between an ejector and grinder pump?
A sewage ejector moves wastewater and solids; a grinder uses a cutting mechanism to reduce solids before pumping. Required flow, lift, discharge distance and sewer-system requirements determine the choice. They are not automatically interchangeable. See Zoeller’s explanation of sewage and grinder pumps.
Why does my sewer pump keep running?
Continuous running and rapid on/off cycling are different symptoms. Possible causes include a float or control fault, backflow through the check valve, restricted discharge or incoming water exceeding capacity. Tell us which behavior you hear; testing is needed before selecting a repair.
My sewer pump alarm is going off. What do I do?
Stop using fixtures that discharge into the system and call for service. If you are unsure which fixtures are connected, pause household water use. Keep away from wastewater and wet electrical equipment. Do not open or enter the basin, bypass the alarm or repeatedly reset a tripping breaker.
Can I flush wipes if I have a grinder pump?
No. Even grinder pumps are damaged by wipes, including those labeled flushable. Wipes wrap around the grinder mechanism, bind the impeller, and cause premature failure. Only human waste and toilet paper should enter any sewer pump system.
Do I need an alarm on my sewer pump?
A high-water alarm can warn that liquid is rising above its normal operating level, giving you time to stop water use and call for help. It does not identify the failed component by itself. We can assess the alarm and controls with the pump; follow your model’s maintenance instructions.
Do you offer 24/7 emergency pump service?
Yes. We offer 24/7 emergency pump service for alarms, pump failures and wastewater backups. Call with your location and symptoms so we can assess the problem and confirm response availability. Keep people and pets away from any sewage while awaiting help.
