Unveiling the Mystery: Why Is My Grinder Pump Not Functioning?

If your grinder pump has stopped working, it can be a major inconvenience. These pumps are essential for removing wastewater from homes that are located below the level of the main sewer line. When a grinder pump fails, it can lead to sewage backups, which can be both unsanitary and expensive to fix.

Common Causes of Grinder Pump Failure

There are a number of reasons why a grinder pump might stop working. Some of the most common causes include:

• Power outage: If there is a power outage, your grinder pump will not be able to operate. Check to see if your neighbors have power, and if they do, then the problem may be with your home’s electrical system.
• Tripped circuit breaker: The circuit breaker that powers your grinder pump may have tripped. This can happen if the pump overloads or if there is a short circuit. Reset the circuit breaker and see if the pump starts working again.
• Clogged pump: The grinder pump can become clogged with debris, such as rags, paper towels, or feminine hygiene products. If the pump is clogged, it will not be able to pump wastewater effectively. Remove the clog and see if the pump starts working again.
• Worn-out impeller: The impeller is the part of the pump that rotates to move wastewater. Over time, the impeller can wear out and become less effective. If the impeller is worn out, the pump will not be able to pump wastewater effectively. Replace the impeller.
• Failed motor: The motor is the part of the pump that powers the impeller. If the motor fails, the pump will not be able to operate. Replace the motor.
• Damaged pump housing: The pump housing is the part of the pump that contains the impeller and motor. If the pump housing is damaged, it can cause the pump to leak or fail. Replace the pump housing.

Troubleshooting Steps

If your grinder pump is not working, there are a few troubleshooting steps you can take to try to fix the problem.

1. Check the power supply: Make sure that the grinder pump is plugged into a working outlet and that the circuit breaker is not tripped.
2. Inspect the pump for clogs: Remove the pump from the sump basin and inspect it for clogs. If you find any clogs, remove them and see if the pump starts working again.
3. Check the impeller: Remove the impeller from the pump and inspect it for wear and damage. If the impeller is worn out or damaged, replace it.
4. Check the motor: Remove the motor from the pump and inspect it for damage. If the motor is damaged, replace it.
5. Check the pump housing: Inspect the pump housing for cracks or damage. If the pump housing is damaged, replace it.

When to Call a Plumber

If you have tried the troubleshooting steps above and your grinder pump is still not working, it is time to call a plumber. A plumber can diagnose the problem and make the necessary repairs.

How to Prevent Grinder Pump Problems

There are a few things you can do to help prevent grinder pump problems:

• Avoid putting non-flushable items down the drain: Only flush human waste, toilet paper, and wastewater down the drain. Avoid flushing items such as rags, paper towels, feminine hygiene products, and diapers.
• Use a garbage disposal sparingly: If you have a garbage disposal, use it sparingly. Do not put large amounts of food waste down the disposal, as this can clog the grinder pump.
• Have your grinder pump serviced regularly: A plumber can service your grinder pump regularly to keep it in good working condition.

If your grinder pump is not working, it is important to troubleshoot the problem and make the necessary repairs as soon as possible. By following the troubleshooting steps above, you can often fix the problem yourself. However, if you are not comfortable working on your grinder pump, it is best to call a plumber.
