The lift station pumps are one of the most used machines in the sewage and construction industry. The lift station pump uses various mechanical parts, such as valves, pumps, electrical connections, etc., to perform.

A single mechanical problem can put the lift station pump out of order. It is why consistent maintenance and checks are essential.

However, the mechanical faults may not always shut the pump down but prevent it from stopping. There are two main areas for the lift station pump owners to check if the machine continues running and won’t shut down:

  • The pipes
  • The tank

Sensors and breakers within the lift station pump are designed to stop the machine from working when needed. However, it’s crucial to turn off the power supply breakers when you test the electrical components of the machine.  

We recommend reaching out to a professional for the testing phase if you are not 100% sure you can handle the task right. You can also install a running time clock or a cycle counter to troubleshoot the lift station pump.

The Lift Station Pump won’t shut Off: What to do

There are multiple reasons why the lift station pump does not shut down. Professionals must pick out the right reason for the pump shutdown failure. Therefore, we will list some of the main causes of why the lift station pump may not shut off.

Saturated Soil Area

The lift station pump may have trouble shutting off because the soil treatment area is too saturated, so the pump does not deliver the dose. The professionals should check for excessive ponding.

Simply put, pump the tanks, and let them empty properly. You may need to perform system repair or even replacement when the tank is empty.

Float Problems

Float within the raw wastewater can be problematic for the lift station pump, preventing it from shutting down properly. The weight freedom determines the weights or the control floats. Users can add water to the mix and see how the lift station pump turns on.

A float rod might be obstructed because of debris within the lift station pump. You can readjust the control floats and channel the obstructions away from the float road.

Lose Impeller on the Shaft

The impeller’s rotation and freedom are other major components that you should consider for the lift station pump. It’s easy to check the impeller as you can turn it off and remove the dosing pump from the water to check its rotation. If there’s some problem with the rotation, the impeller loses and requires maintenance.

Excessive Water Inflow

Increased water inflow can make the lift station pump operate longer, such as if the groundwater enters the pump or if there’s a facility leak. If this is not the case, you may need a larger tank or pump. Therefore, a water waste management professional can help you decide.

Bottom Line

Lift station pumps are an integral part of the water waste management units. They can help move the wastewater to a designated location quicker and make the process easier for professionals.

However, there’s a chance the lift station pump won’t shut off due to float problems, increased water flow, or a loose impeller. You can identify the plausible cause and resolve it accordingly.
