Do Septic Tanks Make Noise

 Do Septic Tanks Make Noise? Deciphering the Sounds from Your Septic System


Homeowners sometimes report odd sounds emanating from their septic systems, raising concerns about the health and functionality of this crucial component of home waste management. But do septic tanks make noise, and if so, what do these sounds mean? Let’s dive into the world of septic systems to understand the symphony of noises they might produce.

Understanding Septic Tank Noises

  • Gurgling Sounds: A common noise from septic tanks, often due to clogged pipes or vent stacks that disrupt the water flow.
  • Bubbling Water: This can indicate a full septic tank or issues with the drain field.
  • Humming from the Motor: If you have a septic system with a pump, a low humming noise may be normal during operation.
  • Alarms or Beeps: Some systems have alarms for high water levels or other malfunctions.

Investigating the Sounds

  • Regular Checks: Periodic inspections by professionals can pre-empt issues that cause noise.
  • Prompt Response: Investigate unusual sounds promptly to avoid more significant issues.
  • Professional Diagnosis: A septic service professional can accurately diagnose and resolve issues related to strange noises.

What to Do if Your Septic Tank is Noisy

  • Don’t ignore: Ignoring septic tank noises can lead to more serious problems.
  • Reduce Water Use: Minimize water usage until a professional can assess the issue.
  • Professional Inspection: Schedule an inspection and pump if necessary.

Preventing Septic Tank Noises

  • Routine Maintenance: Regular maintenance is key to preventing septic system noises.
  • Mindful Flushing: Only human waste and toilet paper should be flushed.
  • Regular Pumping Schedule: Keep to the recommended schedule for pumping your septic tank.


While some noise from a septic system can be normal, particularly from pump-equipped systems, unusual or sudden noises can be a sign of trouble.

Recognizing these sounds early on and understanding what they could mean is essential to maintaining a healthy septic system and preventing more serious issues.
