That Strange Noise in Your Basement Could Be Your Sump Pump Crying for Help
When you’re settling in for the night and hear unusual sounds coming from your basement, it’s natural to feel concerned. If you have a sump pump, those mysterious noises might be your first warning sign that something needs attention. While some operational sounds are completely normal, strange or excessive noises are usually one of the first signs of a problem that shouldn’t be ignored.
Understanding Normal vs. Concerning Sump Pump Sounds
Not every sump pump noise indicates trouble. When your sump pump moves water through the pipe, it must first push out air creating a burping sound. The loud burping sound indicates the pump is starting up and is working as it should. Other noises include a low hum, a light clang at the beginning of a cycle and gurgling. A noisy humming sound coming from your sump pump can be completely normal, especially during operation.
However, higher-quality sump pumps with precision configured components and adequately lubricated often produce less noise. On the other hand, a less expensive unit may make more noise, especially as air escapes from the system. The key is recognizing when sounds become abnormal or excessive.
Decoding Strange Sump Pump Noises
Grinding Sounds
If your sump pump makes a grinding noise, check it as soon as possible. The culprit might be a jammed or defective impeller. A faulty impeller will usually make a grinding noise. An impeller in your sump pump is responsible for suctioning the water that makes its way into your basement. This component is critical for proper operation, so grinding noises require immediate professional attention.
Banging and Clanging
Loose discharge pipes might be the reason why your sump pump is making a banging noise. The discharge pipe is the component that removes water from the sump basin. A clanging noise coming from your sump pump means that one or more parts are vibrating vigorously. While some initial clanging during startup is normal, if you hear a constant clanging that won’t stop, this could mean that your sump pump was not installed properly.
Excessive Humming
If your sump pump is making a humming noise but is not pumping water correctly, you should do a maintenance check to see what might be causing the issue. The source of the humming sounds may be a clogged vent, stuck check valve, frozen discharge pipes, or a broken impeller. When humming becomes louder than usual or the pump isn’t moving water effectively, it’s time to investigate.
Gurgling and Slurping
Sump pumps often make a slurping sound when the pre-set shut-off height for the pump isn’t correctly set. Ideally, the pump should turn off before the point where water moves to the pump’s intake area. A gurgling noise coming from your sump pump indicates that water is flowing back through the discharge pipe. While some gurgling is normal, excessive gurgling may indicate check valve problems.
Continuous Running
If you hear the pump running all the time, it’s likely that the pump isn’t the right size for your basement. Both undersized and oversized pumps are a problem. Ideally, the size of the pump should match the size of the basin where it’s installed. This sizing issue can lead to premature wear and eventual system failure.
When DIY Solutions Might Help
Some sump pump noise issues can be addressed with simple fixes. When your hard-working sump pump develops a banging sound, you may simply need to secure the discharge piping. You could try using wire (12-gauge is ideal) to fasten pipes in place. If you can isolate a specific area of the pipes where the noise is coming from, an extra bracket placed there may resolve the issue.
For clanging sounds, you might consider wrapping the piping with insulation to dampen the sound. You could also silence a banging, clanging sump pump lid by adding rubber grommets underneath. However, these are temporary solutions that address symptoms rather than underlying problems.
When to Call Professional Help
Many sump pump noise issues require professional diagnosis and repair. If you’ve tried troubleshooting your sump pump but can’t resolve the noise issue, it may be time to call in the experts. Loud sump pump noises can indicate a serious problem that, if left unaddressed, could lead to pump failure and significant water damage.
Professional intervention is particularly important for grinding noises, which often indicate impeller problems, or when pumps run continuously. A rattling or grinding noise can indicate something wrong with the impeller or fan. A sump pump that vibrates excessively could be a sign of a damaged impeller. A bent impeller can’t be repaired, unfortunately. If your sump impeller is bent, it will need to be replaced.
The Importance of Regular Maintenance
Sump pumps require occasional maintenance. Just as any other piece of equipment with moving parts, sump pumps are prone to fail from wear and tear, as well as neglect. Some of the tasks your maintenance contractor will perform include running the backup pump (if you have one) to make sure it’s working correctly, testing the pump’s discharge and check valve, and adjusting the float.
Regular professional maintenance can prevent many noise issues from developing and help identify problems before they become costly emergencies. Annual professional sump pump testing and maintenance can keep your pump reliable and in great condition.
