Best Sewage Grinder Pump | Top 10 Grinder & Buying Guide

Last Updated on October 23, 2021 by Cynthia A. Rose

Sewage grinder pumps are used to remove water, solid wastes, and other small materials from your household appliances like toilets and washing machines to the sewer system.

I recently shifted to my new home. And, heard my father talking over the phone about buying the best sewage grinder pump. I didn’t know much about its applications.

So, I asked my father that, why do we need a grinder pump? Then he said that it is for those houses which are near the sewer line. But nowadays, standard homes are built much higher than the septic system. As a result, gravity can pull the wastewater down from the sewage line.

Difference between a sewage pump and a grinder pump:

Sewage pump can handle the solid wastes up to a certain extent. These pumps are generally used in the basement toilets to pull up the sewage to the sewer system. They can move high volume raw waste under low pressure within a short distance.

All grinder pumps are sewage pumps. A low volume of waste is better to move over a longer distance and high pressure. These septic pumps include a cutting mechanism and have blades within them. They are used to grind the hard solids and raw waste materials and creates a slurry before discharging.

Sewage pumps are usually less expensive and tend to use less power. But, they might get clogged because of the hard materials and may tear the pump up.

On the other hand, the grinder pump creates a slurry that is easy to pass through pipes and pumps it to a higher elevation. That’s why it draws more power and is expensive.

So, the difference between the sewage pump vs grinder pump is lucid after this explanation.
