Problems You May Encounter with Your Home’s Grinder Pump


The grinder pump is a part of the sewer system for many homes. Essentially, it functions similar to a garbage disposal, except it is more powerful and located farther along in the plumbing in a tank buried under your property. When the wastewater exiting your home reaches a set level, the pump turns on to move the water toward the civic sewer system—while also grinding down larger solid waste to prevent problems in the municipal sewer lines.

As with any mechanical device that handles a great deal of work around the year, a grinder pump can experience malfunctions. Below are three of the more common grinder pump issues you might run into. Call for professional plumbers when any of these occur!

  • Frozen pump: Your grinder pump is buried down in the ground at a level below the frost line to prevent it from freezing during our chilly winters. However, a frozen pump can still occur for a pump that wasn’t placed deep enough. This will freeze the waste inside and stop the pump from working. It can also inflict serious damage to the pipes. Professionals can solve the problem and bury the pump deeper.
  • Blockage: Grease and dirt can build up in the grinder pump, and create blockage. If you notice slow drains or a large number of clogs—or sewage backs up into your home—then call immediately for professional plumbers.
  • Clots: A large enough item becoming stuck inside the pump will then allow smaller items to build up. The pump will start to work slower or make loud noises. Plumbers will need to clear out the clotting before the pump breaks down.
