Don’t Ignore the Warning
Lift Station Alarm On?
A high-water alarm means the wastewater level has reached a point the system wasn’t supposed to reach during normal operation.
The cause may be a failed pump, stuck float, blocked impeller, valve problem, discharge restriction, control issue, power problem, or inflow the station isn’t keeping up with.
The important thing is to respond before an alarm becomes a backup.
If the Alarm Is Active
- Reduce wastewater use where practical.
- Do not enter the wet well or basin.
- Do not repeatedly silence, reset, or bypass the alarm without determining why it activated.
- Call Pacific Standard Plumbing for diagnosis.
The alarm is the warning. The backup is what you’re trying to prevent.
Look at the Whole System
The Pump Is Only One Part of the Station.
Replacing a failed pump doesn’t solve much if the condition behind the failure is still there.
A lift station depends on the basin, pumps, level controls, valves, discharge piping, alarm system, and downstream drainage working together.
Pacific Standard Plumbing looks at the system—not just the component that stopped working.
How a Lift Station Moves Wastewater
01
Wastewater Inlet
Drain lines from the building carry wastewater into the station.
02
Wet Well / Basin
Holds incoming wastewater until it reaches the pump-on level.
03
Floats / Level Controls
Sense the water level and tell the pumps when to start and stop.
04
Pump(s)
Lift wastewater out of the basin. Duplex stations alternate two pumps for backup.
05
Check & Isolation Valves
Stop pumped wastewater from flowing back and allow safe service.
06
Discharge Piping
Carries wastewater from the pumps up to the gravity line.
07
Gravity Sewer
From here, gravity takes it to the public sewer.
Connected to Every Step
High-Water Alarm & Control Panel
Monitors the basin level, runs and alternates the pumps, and warns your team when wastewater rises too high, before it becomes a backup.
Pacific Standard Plumbing — Plumbing & Mechanical Service Across the System
Commercial Lift Station Service
Find the Failure. Restore the System.
From an alarm call to a planned pump replacement, we diagnose the system first so the repair addresses the actual problem.
System Inspection & Diagnosis
Evaluate pumps, basin conditions, level controls, valves, accessible piping, alarms, and system operation to isolate the cause of the problem.
Pump Repair & Replacement
Troubleshoot failed or underperforming sewage and wastewater pumps and repair or replace equipment when appropriate.
Float & Level Control Service
Inspect and service accessible floats and level-control components that tell the pumps when to start and stop.
Check Valves & Discharge Piping
Diagnose leaking or malfunctioning check valves, isolation valves, discharge piping, and related plumbing that can prevent the station from operating correctly.
Sewage Ejector Systems
Service pumps and associated plumbing for below-grade restrooms, parking structures, mechanical spaces, and other areas that cannot drain to the sewer by gravity.
Preventive Maintenance
Routine system inspection and service designed to identify pump, float, valve, piping, and basin problems before they become emergency failures.
Redundancy Matters
One Pump Running Isn’t the Same as a Healthy Station.
Many commercial lift stations use two pumps so the system has additional capacity and redundancy.
If one pump fails, the second pump may keep wastewater moving—but the station has lost part of the protection built into the system.
A station that appears to be “working” can still have:
One Failed Pump
The remaining pump is carrying the load alone.
Uneven Pump Hours
One pump may be doing significantly more work than the other.
Failed Alternation
The pumps may not be taking turns as intended.
Loss of Backup Capacity
A surge in wastewater—or failure of the remaining pump—can turn a maintenance issue into an emergency.
If one pump is down, don’t wait for the second one to tell you.
Duplex stations commonly use lead/lag operation and alternation to share duty between pumps and retain additional pumping capacity, as described in U.S. EPA pump-station guidance.
When Gravity Isn’t an Option
When the Station Stops Pumping, Wastewater Has Nowhere to Go.
For fixtures below the sanitary sewer elevation, the lift station or sewage ejector is what makes drainage possible.
If the system stops removing wastewater, every connected fixture can continue adding water to the basin.
Pacific Standard Plumbing provides 24/7 commercial response for high-water alarms, sewage ejector failures, pump problems, and wastewater backups.
Restore the system before a pump problem becomes a property problem.
Know What You’re Seeing
What Is Your Lift Station Telling You?
Call Now
High-Water Alarm
The system isn’t maintaining its normal wastewater level. A pump, level control, valve, discharge, electrical, or inflow condition may be responsible.
Call Now
Lower-Level Drains Backing Up
Wastewater may no longer be leaving the basin or ejector system properly.
Call Promptly
One Pump Isn’t Running
In a duplex system, the remaining pump may still keep the station operating, but redundancy and available capacity have been reduced.
Schedule Promptly
Pump Runs Constantly
Can point to inadequate pumping, unusual inflow, discharge restriction, check-valve problems, or a control issue.
Schedule Promptly
Pump Starts and Stops Repeatedly
Short cycling increases wear and can point toward level-control, basin, system-sizing, or operating problems.
Investigate
One Pump Has Significantly More Run Time
Where run-hour information is available, a large imbalance can help identify alternation, pump-performance, or control problems.
Investigate
Banging When the Pump Stops
Can point toward check-valve operation or conditions in the discharge piping.
Investigate
Sewage Odor Around the Station
Odor can accompany standing wastewater, excessive buildup, venting problems, leaks, or other station conditions.
Not sure what the alarm or symptom means? That’s what the service call is for.
Before the Alarm
Don’t Maintain the Calendar. Maintain the System.
There isn’t one maintenance interval that fits every lift station.
The right schedule depends on the equipment, number of pumps, wastewater conditions, system usage, service history, and what happens to the property if the station fails.
Pacific Standard Plumbing can help establish a recurring inspection process around the actual system.
Pump Operation
Check pump operation and look for unusual noise, vibration, clogging, wear, or changes in performance.
Floats & Level Controls
Inspect accessible level devices for buildup, obstruction, damage, and proper operation.
Check & Isolation Valves
Look for leakage, improper closure, unusual operation, or conditions that allow wastewater to return toward the basin.
Alarm Function
Confirm the high-water warning system activates so the property team has notice before wastewater reaches a critical level.
Basin Condition
Observe grease, solids, debris, and other accumulation that can interfere with pumps and level controls or indicate specialized cleaning is needed.
Pump Hours & Cycles
Where the equipment provides the information, compare pump run hours and cycle counts to identify changing conditions or uneven operation.
Service History
Document findings, repairs, component replacements, and recurring problems so each visit builds on the last one.
Pump-station maintenance guidance from the U.S. EPA emphasizes inspection of pumps, controls, valves, wet wells, alarms, and operating records rather than treating the pump as an isolated component.
Don’t Just Swap the Pump
Find Out Why It Failed.
A failed pump may be the problem—or the result of another problem.
Debris, grease, damaged impellers, malfunctioning valves, level-control problems, discharge restrictions, equipment wear, and electrical faults can all affect station performance.
Before recommending replacement, the goal is to understand what happened and what the system needs next.
Diagnose
Determine whether the failure is related to the pump, basin, level controls, valves, piping, discharge system, electrical controls, or another condition.
Repair
Correct serviceable plumbing and mechanical problems where practical.
Replace
Replace failed pumps or components when repair is no longer reasonable.
Verify
Cycle the system and confirm the repaired or replaced equipment is operating as intended.
Fix the failed component. Address the condition behind it.
Find the Right Failure
Not Every Lift Station Problem Is a Plumbing Problem.
Pumps, floats, valves, piping, controls, alarms, and electrical power all have to work together.
Our job is to diagnose the system far enough to determine where the failure is coming from.
If the problem is within the plumbing or mechanical system, Pacific Standard Plumbing can address it.
If the failure requires electrical control-panel, wiring, or other work outside our plumbing scope, we’ll identify that condition so the appropriate licensed trade can be brought in.
The goal isn’t to sell the wrong repair. It’s to find the right problem.
Built for Managed Properties
The System May Be Out of Sight. It Shouldn’t Be Out of Mind.
Lift stations are easy to overlook because, when they’re working correctly, nobody thinks about them.
That changes immediately when an alarm activates or a lower level starts backing up.
Pacific Standard Plumbing can help turn lift-station service from a series of reactive emergencies into a documented maintenance process.
System Records
Keep equipment, pump, repair, and maintenance information organized by property.
Recurring Inspections
Establish service intervals based on configuration, usage, equipment recommendations, operating history, and consequences of failure.
Repair History
Track recurring failures and component replacements instead of treating every service call as an isolated event.
Multi-Property Support
Coordinate lift-station and sewage-ejector service across commercial buildings, HOAs, hotels, healthcare facilities, multifamily properties, and managed portfolios.
FAQ
Lift Station & Sewage Ejector Repair FAQs
What is a lift station?
A lift station collects wastewater in a basin or wet well and uses one or more pumps to move it to a higher elevation where gravity drainage can continue.
What is a sewage ejector?
A sewage ejector performs the same basic function on a smaller scale and is commonly used for fixtures or areas located below the elevation of the gravity sewer.
What should I do if my lift station alarm is on?
Reduce wastewater use where practical and call for service.
Do not enter the wet well or basin, and do not repeatedly bypass or reset the alarm without determining why it activated.
What causes a high-water alarm?
Possible causes include pump failure, blocked pumps, float or level-control problems, malfunctioning valves, discharge restrictions, electrical faults, loss of power, or wastewater entering the station faster than it can currently be pumped out.
What if one pump in a two-pump system is still working?
The station may continue operating, but it has lost redundancy and potentially part of its pumping capacity.
A failed second pump should be addressed before the remaining pump becomes the only thing standing between normal operation and a wastewater backup.
Why do duplex lift stations alternate pumps?
Alternation helps distribute operation between the pumps rather than repeatedly using the same pump as the primary unit.
How often should a commercial lift station be serviced?
There is no single interval that fits every system.
Frequency should reflect equipment configuration, wastewater characteristics, usage, service history, manufacturer recommendations, and the consequences of failure.
Do you replace lift-station and sewage-ejector pumps?
Yes. Pacific Standard Plumbing can diagnose and replace commercial sewage and wastewater pumps when replacement is appropriate.
Do you service floats and check valves?
Yes. Floats, accessible level-control components, check valves, isolation valves, and associated piping can be evaluated during service.
Do you repair electrical control panels?
Pacific Standard Plumbing can help diagnose whether the problem appears to be mechanical, plumbing-related, or electrical.
Electrical panel, wiring, and control work that requires another license must be performed by the appropriately licensed trade.
Do you clean or pump out wet wells?
We can inspect basin conditions and identify when accumulated grease, solids, or debris may require specialized wet-well cleaning or vacuum service.
Specialized pumping or waste-removal services may require a separate provider depending on the system and conditions.
Do you provide 24/7 service?
Yes. For urgent lift-station alarms, sewage ejector failures, or wastewater backups, call 858.255.1654.
