Troubleshooting Frequent Sewage Pump Noises With Simple Solutions

Posted on: 6 July 2015


The sewage pump that you have in your septic system may be tucked out of sight, but when it starts to have issues, there is no way it will be out of mind. A failing sewage pump almost always starts making noises before it completely fails and as a homeowner, learning to recognize these noises and what they could mean could save you a lot of time and money down the road. Here are a few of the most common noises a sewage pump can make and what the pump could be trying to tell you. 

Gurgling or Bubbling 

It is expected that on occasion you will hear a gurgle or bubble when you flush the toilet or water is escaping down the drain. However, this is not a noise that you should be hearing all of the time, especially when no waste is being added to the sewage line via the toilet or a drain. If you do hear these noises often without a reasonable explanation, it means that air is making its way into the sewage pump at some point, which would indicate that there is a leak in the line leading to the pump itself. You should have a plumber come out and track down the problem quickly, as excess air in the pump can easily cause motor failure. 

Clanging or Banging 

To hear something clanking and banging from your sewer system will always make you a little nervous and will definitely be the type of sound that is hard to ignore. If this is a sound that is coming from the sewage pump, there is a good chance that the problem will have a fairly simple solution. Older sewage pumps tend to come loose from their housing when screws and other fastening hardware start to deteriorate. So this means that stopping all of the racket will be as simple as removing the pump and replacing damaged or missing hardware. 

Grinding Motor Sounds 

Just before a sewage pump fails completely, it will offer you a telltale warning signal in the sound of a grinding motor. You should look at this noise as the sound of a motor that is trying way too hard to push sewage through the lines, as this is actually why the noise occurs. As the motor ages, it starts to wear down and will not have the same amount of power, which will often cause this grinding noise. 

If you believe that your sewage pump is either getting ready to fail or trying to tell you something that you do not understand, talk to a contractor (such as Fyle's Honey Wagon) for help and advice. The faster you get help, the less likely it will be that you have to have the whole pump replaced.
