Basements are often the unsung heroes of home functionality, serving as storage areas or extra living spaces. However, they’re also susceptible to water damage, making a sump pump an essential piece of equipment. Though reliable, sump pumps can occasionally experience problems. Understanding and addressing these issues promptly is crucial for keeping your home dry and damage-free.
This guide explores seven common sump pump problems, how to troubleshoot them, and when to seek basement sump pump services for professional help.
1. Pump Fails to Activate
Causes
The primary culprits include power failures, debris jamming the float switch, or mechanical malfunctions like a burnt-out motor. Improper installation, such as an incorrectly set float switch, can also prevent activation.
Symptoms
A silent pump and rising water levels in the sump basin signal trouble.
Troubleshooting
- Ensure the pump is plugged in and check the circuit breaker.
- Remove debris obstructing the float switch or impeller.
- Replace a defective float switch or upgrade the pump if it’s too small for your home’s needs.
Prevention Tip: Regularly clean the sump basin to keep the float switch and pump components in optimal condition.
2. Pump Has No Power
Causes
Power outages, tripped circuit breakers, faulty wiring, or a dead battery in backup systems are common reasons for power loss.
Symptoms
The pump remains inactive, even as water levels rise.
Troubleshooting
- Inspect electrical connections and reset the circuit breaker.
- Replace a dead backup battery or faulty internal components.
Prevention Tip: Regularly test battery backups and replace them as needed to ensure reliable operation during power outages.
3. Pump Runs Continuously
Causes
A stuck float switch, a malfunctioning check valve, or an undersized pump can result in nonstop operation. This can also occur if water flows back into the basin due to a damaged check valve.
Symptoms
Continuous pump activity or a spike in electricity bills.
Troubleshooting
- Replace a faulty float switch.
- Inspect and, if necessary, replace the check valve to prevent backflow.
- Upgrade to a larger pump if the existing one struggles to handle water volume.
Prevention Tip: Ensure proper installation of the check valve and use a sump pump with adequate capacity for your home.
4. Pump Makes Unusual Noises
Causes
Grinding, rattling, or excessive vibration may result from debris in the impeller, worn bearings, or improper installation.
Symptoms
Unusual sounds from the pump during operation.
Troubleshooting
- Clear debris from the impeller.
- Replace worn bearings or securely reinstall the pump to reduce vibrations.
Prevention Tip: Schedule routine maintenance to identify and resolve issues before they escalate.
5. Pump Works But Doesn’t Remove Water
Causes
A clogged discharge pipe, an underpowered pump, or a stuck check valve can prevent the pump from effectively removing water.
Symptoms
Persistent water in the basin or occasional basement flooding.
Troubleshooting
- Inspect the discharge pipe for blockages and clear them.
- Replace the check valve if it’s stuck or misaligned.
- Upgrade to a more powerful pump if necessary.
Prevention Tip: Regularly clean the discharge line to ensure uninterrupted water flow.
6. Pump Stops Before Fully Draining Basin
Causes
This can happen due to an improperly set float switch or an overheating pump.
Symptoms
The pump shuts off prematurely, leaving water in the basin.
Troubleshooting
- Adjust the float switch height to allow complete drainage.
- Clean debris from the pump to prevent overheating.
Prevention Tip: Perform routine cleaning and maintenance to prevent mechanical issues.
7. Sump Pump Emits Foul Odors
Causes
Stagnant water, bacterial growth, or a dry trap in the discharge line often cause bad smells.
Symptoms
Noticeable foul odors near the sump pump.
Troubleshooting
- Clean the sump basin thoroughly and use a small amount of bleach to eliminate bacteria.
- Add water to the discharge trap to block sewer gas from entering your home.
Prevention Tip: Clean the sump basin regularly to prevent buildup of organic material.
