Common Sump Pump Noises and What They Mean
1. A Constant Humming Sound
A quiet hum is normal when your sump pump is running. However, if the hum is unusually loud or continues even when the pump isn’t actively removing water, it could signal a problem. The most common causes include a jammed impeller or debris clogging the pump. Ignoring this noise can lead to overheating or even a complete system failure.
2. Gurgling or Bubbling Noises
If you hear a gurgling or bubbling sound as water drains from the sump pit, it might not be anything serious. Often, this means air is escaping through the discharge line. Installing a check valve or adjusting the discharge pipe can quiet things down. Still, if the gurgling grows louder over time, it could indicate improper drainage or trapped air that needs professional attention.
3. Clanking or Banging Sounds
A clank or bang when your pump cycles on or off usually points to loose or vibrating pipes. When water rushes through the discharge line, it can cause the pipes to knock against nearby surfaces. Adding pipe insulation or tightening brackets can reduce this noise—but if you’re unsure how, it’s best to call in an expert.
4. Grinding or Screeching Noises
A grinding or screeching sound is never a good sign. These noises often mean your pump’s motor or impeller is wearing out. This type of issue won’t fix itself, and running the pump in this condition can lead to permanent damage. We recommend turning off the unit and contacting a service professional right away.
5. Rapid Clicking or Tapping
If you notice a fast, repetitive clicking sound, your sump pump switch might be stuck or malfunctioning. This can prevent your pump from activating when needed, leaving your basement vulnerable to flooding. Replacing the switch is usually a quick fix—but catching it early is key.
How to Prevent Sump Pump Noise
Routine maintenance goes a long way toward keeping your sump pump quiet and reliable. Clean the sump pit regularly, inspect the discharge line for obstructions, and test the pump before heavy rain seasons. A yearly inspection from a licensed service professional can also help you catch small issues before they turn into big problems.
At AW Heating & Cooling, we understand that a noisy sump pump is more than just an annoyance—it’s a warning sign that your system may need attention. We can diagnose the issue quickly, repair or replace components as needed, and ensure your pump is ready to protect your home year-round.
