Unlike standard septic pumps that simply pump effluent through the septic system, the best sewage grinder pumps incorporate a grinding mechanism that chops and grinds things up to help prevent clogging and septic backflow and to better prepare the effluent for the leech field.
The bad news is that septic grinder pumps cost more money than standard septic pumps because the grinding assembly needs to be quite powerful and robust. It’s like adding a kitchen garbage disposal to a standard sewage pump.
Unlike the standard sewage pumps, grinder pumps feature grinder blades that are essential in chopping the sewage. Besides, you can rely on it to pump into the sewer or from the drain to your leech field area.

Frequently Asked Questions
How much does a sewage grinder pump cost?
- As a general rule sewage grinder pumps costs about twice as much money as standard septic pumps and septic aerator pumps. A $200 septic pump would be around $400 with a grinder attached. This is primarily due to the additionaly hardware and more powerful motor required to run both the pump and grinding blades.
How long do grinder pumps last?
- Grinder pumps lasting 7-8 years is considered average and 10-12 years old is exceptional. Longevity can be related to how often the pump runs, and what kind of waste is run through the septic system. The harder the grinder pump has to work, the shorter it will last in the long run.
Why is my grinder pump so loud?
- Noisy grinder pumps can be clogged with effluent or other objects. If the noise is a screeching or loud humming sound it could also be the bearings in the pump motor wearing out and going bad.
