Sewage pump alarm going off — what it means and what to do now
A sewage pump alarm is a warning that the system is no longer operating safely. This guide explains why alarms activate, what risks are involved, and the immediate steps you should take to avoid flooding or damage.
A sewage pump alarm is triggered when wastewater levels rise beyond safe limits or when a system fault is detected. Fast action is critical to prevent sewage backup, flooding and equipment damage.

Why sewage pump alarms activate
Most sewage pump alarms activate due to rising sewage levels, pump failure or control faults. Identifying the cause quickly helps prevent flooding and serious system damage.
Request urgent diagnosis →High sewage level
Wastewater is rising because the pump is not clearing the chamber.
Pump not running
Electrical or mechanical faults prevent the pump from operating.
Severe blockage
Wipes or debris stop the pump from moving sewage effectively.
Float switch issue
Failed or jammed floats trigger false or continuous alarms.
Control panel fault
Alarm relays or sensors malfunction inside the control panel.
Power supply issue
Loss of power or tripped breakers stop the pump operating.
Water ingress
Moisture inside electrics causes alarm activation.
System overload
Excessive inflow overwhelms the pump capacity.
Why alarms must not be ignored

Early intervention reduces risk, cost and long-term system damage.
Frequently asked questions
What should I do when a sewage pump alarm goes off?
Limit water use immediately and contact a pump engineer to diagnose the cause before flooding occurs.
Is a sewage pump alarm an emergency?
Yes. An active alarm usually indicates rising sewage levels or system failure.
Can I silence the alarm?
You may silence it temporarily, but the underlying fault must be resolved to prevent flooding.
