why does my sewage pump keep running

Is the constant hum of your sewage pump keeping you up at night? Are you puzzled as to why it keeps running without pause? Well, you’re not alone. Many homeowners have faced this persistent issue, and in this article, we’ll delve into the common reasons why your sewage pump may be on an endless loop. From potential causes such as mechanical malfunctions to electrical mishaps, we’ll explore the ins and outs of sewage pump operation to help you uncover the root cause of the issue. So, if you’re tired of hearing your sewage pump’s incessant whir, read on to discover the possible reasons behind this mystery and how to tackle it head-on!

Common Causes of a Sewage Pump Running Continuously

Various reasons are behind the continuous running of a sewage water pump. If your water pump is also running continuously, there is a high chance that the reason is among them.

High Water Usage

Increased water usage in a property can result in a higher volume of wastewater pumped into the sewage system, causing the pump to work more frequently. Factors such as the following can lead to this situation:

Large Gatherings or Events

Hosting parties, gatherings, or events that involve heavy water usage, such as excessive flushing, running multiple appliances simultaneously, or increased laundry, can overload the sewage system and cause the pump to run continuously.

Water Leaks

Undetected leaks in plumbing fixtures or pipes can lead to continuous water flow, resulting in higher wastewater generation and increased pump activity.

Faulty Float Switch

The float switch is a crucial component of the sewage pump that triggers the pump to turn on and off based on the water level in the pit. If the float switch is malfunctioning, it can cause the pump to run continuously. Possible causes of a faulty float switch include:

  • Misalignment: The float switch may become misaligned due to debris, sediment buildup, or mechanical issues, causing it to not accurately sense the water level and keep the pump running continuously.
  • Electrical malfunction: The electrical components of the float switch, such as the wiring or contacts, may wear out or get damaged, resulting in improper functioning and continuous operation of the pump.

Clogged or Blocked Discharge Pipe

The discharge pipe carries the wastewater from the pump to the sewage system. If it becomes clogged or blocked, it can obstruct the proper flow of wastewater, causing the pump to run continuously. Common causes of a clogged or blocked discharge pipe include:

  • Debris or solid waste: Accumulating debris, solid waste, or other foreign objects in the discharge pipe can restrict the wastewater flow and lead to continuous pump operation.
  • Sedimentation: Over time, sedimentation or buildup of sludge, grease, or other materials in the discharge pipe can cause blockages, hindering the proper functioning of the sewage pump.

Pump or Motor Issues

Mechanical problems with the pump or motor can also cause the pump to keep running without properly pumping out the wastewater. Some potential causes include:

  • Worn-out impeller: The impeller is responsible for pushing the wastewater out of the pump. If it becomes worn out or damaged, it may not be able to generate enough pressure to pump out the wastewater effectively, resulting in continuous pump operation.
  • Faulty motor: Issues with the engine, such as electrical malfunctions, motor overheating, or mechanical failure, can also cause the sewage pump to run as it struggles to operate appropriately.

It’s important to note that these causes may not always occur in isolation, and multiple factors can contribute to a sewage pump running continuously. Proper diagnosis and troubleshooting may be required to identify the specific cause and implement the appropriate solution. Seeking professional help from a qualified plumber or sewage pump technician may be necessary for accurate diagnosis and repair.

Troubleshooting and Solutions

Several potential solutions exist when troubleshooting a sewage pump that is running continuously. First, managing water usage by reducing excessive water consumption during peak times, fixing leaks, and spreading water usage can prevent the sewage system overload and stop the pump from running continuously. 

Checking and repairing the float switch is also essential, as misalignment, debris, or electrical issues can cause it to malfunction and keep the pump running. Clearing the discharge pipe from clogs or blockages using snaking, jetting, or chemical treatments can restore proper flow and prevent continuous pump operation. 

Repairing pump components such as a worn-out impeller, faulty motor, or electrical malfunctions can also restore the pump’s proper operation. In some cases, professional help from a qualified plumber or sewage pump technician may be necessary for accurate diagnosis and repair. It’s crucial to address the root cause of the continuous pump operation to prevent further damage and ensure efficient sewage system functioning.

Final Thought

A sewage pump running continuously can be caused by various factors. By implementing effective troubleshooting and solutions such as regulating water usage, replacing or repairing components, and seeking expert assistance, you can eliminate the underlying cause of the issue and prevent the pump from running continuously. Regular maintenance and prompt repairs can ensure the efficient functioning of the sewage system and prevent further damage. If you’re experiencing issues with your sewage pump running continuously, it’s essential to promptly identify and address the underlying problem to avoid potential injury and ensure proper operation.
