When Your Sewer Pump Fails, Sewage Has Nowhere to Go But Back Into Your Home
A sewer pump moves wastewater from below-grade fixtures — basement bathrooms, laundry rooms, and floor drains — up to the main sewer line or septic system. When gravity can't do the job, the pump does. When the pump fails, that waste has nowhere to go. It fills the basin, overflows onto the floor, and floods your basement with raw sewage. The damage is immediate, the health hazard is serious, and the cost of cleanup and restoration dwarfs the cost of pump repair or replacement.
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 all of Whatcom and Skagit Counties.
What to Look for in a Sewer Pump Specialist
Sewer pump work involves plumbing, electrical, and often confined space entry into a sewage basin. 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. And the electrical must be on a dedicated circuit with proper GFCI protection. 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. The electrical must be on a dedicated GFCI-protected circuit. 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?
Sewage ejector pump replacement typically runs $800 to $2,500 including the pump, check valve, float switch verification, basin cleaning, and full cycle testing. Grinder pumps run $2,000 to $4,500 due to higher pump cost and complexity. We quote upfront.
How long do sewer pumps last?
Most residential sewage ejector pumps last 7 to 15 years depending on usage, maintenance, and what goes into the system. Grinder pumps typically last 8 to 15 years. Heavy use, wipes, and debris shorten pump life significantly.
What is the difference between an ejector and grinder pump?
An ejector pump handles sewage solids up to 2 inches and pumps against moderate head pressure. A grinder pump grinds all solids into slurry and pumps against high head pressure through small diameter pipe. Grinder pumps are used when the sewer main is significantly higher or farther away.
Why does my sewer pump keep running?
Most common cause is a failed check valve allowing sewage to flow back into the basin after the pump shuts off. The pump empties the basin, shuts off, sewage flows back in, and the pump turns on again endlessly. A stuck float switch or leak in the discharge pipe can also cause this.
My sewer pump alarm is going off. What do I do?
Stop using all water immediately — no flushing, no sinks, no showers, no laundry. The alarm means the basin level is dangerously high and the pump isn't keeping up or has failed. Call us immediately for emergency service before sewage overflows.
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?
Yes. A high water alarm is your only warning before sewage overflows onto your floor. Without an alarm, you won't know the pump has failed until raw sewage is flooding your basement. We install audible and visual alarms on every pump system.
Do you offer 24/7 emergency pump service?
Yes. A failed sewer pump is a sewage emergency. When your pump stops working, the basin fills and overflows with raw sewage creating a biohazard and property damage. We respond 24/7 to diagnose, repair, or replace failed pumps immediately.

We install, repair, and replace sewer pumps across all of Whatcom and Skagit Counties including Bellingham, Mount Vernon, Anacortes, Burlington, Sedro Woolley, Ferndale, Lynden, and surrounding areas.
