February 24, 2026 By Brent D. Hershey

A grinder pump is an essential part of your septic system, which is a small sewage treatment plant for your home that uses septic systems helps to increase the service life of the waste. But grinder pumps, as with all other mechanical systems, have the potential for causing problems and negative effects on your septic system. If your grinder pump has been troubling you of late, you’re not the only one. Whether you are noticing strange sounds, lack of drainage or even being forced to endure the smell emanating from your drains these problems can signal a much larger issue that must be resolved ASAP.

In today’s blog post, we’re going to explore the typical causes behind your hiccups-acting grinder pump (a septic grinder pump malfunction), how you can try to troubleshoot it, and finally when it’s time for a professional to step in on a septic grinder pump repair. As an authority on nearby sewage services, however, we’re here to lend you some useful advice for grinder pump maintenance and how-to’s that will keep your system working its best.

What is a Grinder Pump and Why Do I Need It?

Before we get into the problem list I’ve put together, it’s essential to understand what a grinder pump is doing: Purchasing a grinder pump whether for your home or business can be an expensive fling, which is why we here at ASP want to give you some advice before investing in the purchase. What Is A Grinder Pump? A grinder pump is necessary if you live in a low water pressure area or dependent on septic systems.

Your home discharges wastewater into the grinder pump’s holding tank. The pump then grinds the waste into a fine slurry and expels it through the pipes and into the municipal sewer or septic system. And without this pump, solid waste could block your pipes (leading to backups and other septic system issues).

When your grinder pump fails, the waste removal process becomes impaired resulting in inconveniences and a mess you have to deal with.

Typical Grinder Pump Problems and How to Solve Them

1.Grinder Pump Keeps Running Constantly

A grinding sound coming from your grinder pump, when no water is being used in the house, is another warning that something is clogged. This is may mean that the float switch, which signals the pump to turn on, is stuck or defective.

What to do:

  • See if the float is also hung up, or possibly dirty. You may be able to wiggle the float a little and cure this condition.
  • If this doesn’t solve the problem, it could indicate an electrical issue, like a broken capacitor or unfortunately-wired air conditioner.

2.Grinder Pump Not Turning On

There are a few things it could mean if your grinder pump won’t turn on:

  • The pump’s electrical button has gone bad.
  • The motor has failed.
  • The pump is jammed or impeller is bad.

What to do:

  • First, make sure power isn’t flowing to the pump by examining the circuit breaker.
  • If it still won’t turn on, check the motor and impeller for physical damage.

3.Grinder Pump Making Strange Noises

If you do hear loud grinding or other noises that aren’t normal while the grinder pump is operating, there may be some debris stuck in the impeller, or the pump might be having a hard time chopping and moving waste. These sounds mean the pump is working up against an excess of resistance and opening itself up to unnecessary wear and tear.

What to do:

  • Shut off the power to the grinder pump and clear any foreign objects by pumping on the impeller.
  • If the noise doesn’t go away, now might be the time to call in a pro for septic grinder pump repair they may have damaged it internally.

4. Little or No Water Floworgeslowdrainage

If you see that the water is draining slowly (or not at all) then it could be a result of your grinder pump having difficulty with getting solid waste through the system. This may be caused by an obstruction, broken tubing or pump failure.

What to do:

  • Look for clogs of visible nature in the discharge line or pipes.
  • If you think it is inside the pump, like a bad grinder pump, you may want to have a pro check and possibly service that pump.

5. Smells in the vicinity of the Grinder Pump

Foul odor outside the grinder pump is an indicator that something is just not right. This could signal a septic emergency service scenario or simply a need for your pump to be more efficient in moving waste throughout.

What to do:

  • Make sure the lid on your grinder pump access is sealed tight to keep odors from leaking.
  • If the smells remain, it could be an indication that the pump might not be running at its best.
