How To Fix a Noisy Sump Pump

A noisy sump pump is no fun, and while it may seem like an innocuous issue, it can indicate a critical malfunction with your system. The longer you ignore the noise, the greater the damage your sump pump can suffer. Common causes of sump pump noises include debris buildup, component failure, poor installation, and lack of maintenance.

If you notice that your sump pump isn’t working as it should, it’s advisable to shut it off immediately. You should not attempt to repair your pump yourself, as you risk electric shock, personal injury, and fire if you miss a critical step. At C.B. Lucas, our licensed and insured technicians can inspect your pump to determine the cause of the malfunction, and we’ll promptly perform the necessary repairs or adjustments.

What Does a Bad Sump Pump Sound Like?

A properly functioning sump pump should not emit intrusive noises that disrupt your home. When everything is working the way it should, most sump pumps generate a steady hum. This may involve intermittent “thumps,” slurps, or grinding. However, these sounds should not be overwhelming or constant.

Constantly Running

It’s normal to hear periodic gurgling and sloshing, but if it’s constant and sounds more like a washing machine, it’s a problem. This can indicate that you have the wrong size pump, the float switch has failed, or the check valve is broken. It can also indicate a problem with a clogged discharge pipe.

Clanging

If your sump pump is improperly installed, it’s quite possible you’ll hear it making clanging noises. Clanging sounds can also happen because the sump pump needs more insulation added to the sump pit. Clanging is often accompanied by heavy vibration. Adding insulation can dampen the sound and restore your home’s peace and quiet.

Grinding

Grinding is the result of a faulty impeller blade. If you hear grinding, call your plumber immediately. Continuing to operate with a faulty impeller can cause excessive damage to the unit that will require replacing the entire sump pump.

Vibrating or Buzzing

Have you noticed that the sound of your sump pump reminds you of your garage door? This is most likely the result of improper installation or alignment. Wrapping the sump pump can often resolve the problem and reduce the prevalence of these sounds.

Squealing

Squealing, screeching, or whining sounds are often the result of a faulty impeller. When the impeller freezes or breaks, these noises often worsen quickly and become ever louder. In some cases, these noises may be the result of defective shaft bearings. As these suffer more damage, the noises will increase in volume and pitch.
