Schedule OnlineCommon Sump Pump Problems We Fix
Most sump pump failures begin with warning signs such as unusual noises, constant operation, or a complete loss of function. The table below outlines common symptoms and their likely causes.
| Symptom | Likely Cause |
|---|---|
| Pump runs constantly / won’t shut off | Stuck float switch, failed check valve, or undersized pump |
| Pump won’t turn on | Lost power, tripped GFCI, or failed float switch |
| Motor hums but no water pumps out | Clogged or jammed impeller, or stuck check valve |
| Loud rattling or grinding noise | Damaged impeller or worn motor bearings |
| Excessive vibration | Debris in the impeller or pump not seated properly |
| Frequent on/off cycling | Float set too low, oversized pump, or faulty check valve |
| Water stays in the pit | Clogged or frozen discharge line, or failed pump |
| Rust or visible corrosion | Aging unit or iron-ochre bacteria buildup |
A sump pump not working properly can result from electrical issues, worn components, clogged discharge lines, or age-related failures. Our technicians identify the exact cause and explain repair options before work begins.
A sump pump making loud noise often indicates a damaged impeller, worn bearings, or trapped debris. Addressing these issues early can help prevent complete pump failure.
Why Is My Sump Pump Running Constantly (or Not at All)?
A sump pump that runs constantly is usually caused by a stuck float switch, a failed check valve, or a pump that is undersized for the amount of groundwater entering the pit. If the motor runs but water is not leaving the basin, a clogged impeller or discharge problem may be preventing proper operation.
A sump pump won't turn on is commonly caused by a tripped breaker, unplugged piggyback switch, failed float switch, power loss, or motor failure.
Before scheduling service, homeowners can safely check:
- Circuit breaker status
- GFCI outlet condition
- Power cord connections
- Piggyback plug configuration
- Float switch movement
If these checks do not restore operation, professional diagnosis is recommended. Sump pumps operate automatically during storms, so reliability is critical when heavy rain arrives.
Repair or Replace Your Sump Pump?
Repair a sump pump that is under about seven years old when the issue involves a float switch, check valve, clog, or similar repairable component. Replace it when the unit reaches 7 to 10 years of age, the motor has failed, or the system has already allowed flooding to occur.
Most homeowners asking how long do sump pumps last can expect a service life of approximately 7 to 10 years under normal conditions. Systems that cycle frequently because of high groundwater levels may wear out sooner.
If replacement is recommended, our team can discuss sump pump installation options and help you evaluate battery backup systems. Adding backup protection ensures a power outage during a storm does not leave your basement vulnerable to flooding.
For homeowners debating repair or replace sump pump decisions, we provide honest recommendations based on age, condition, repair costs, and flood risk.
