Feb 28, 2021 Grinder pumps are often necessary when a home is at a lower level then the municipal sewer line or septic tank. Gravity is usually the agent by which wastewater travels out of a home. If the topography of a homes location makes this an impossibility, a grinder pump is required to prevent sewage and wastewater from backing up.
Sewer ejector pumps can have a discharge line up to 3 in diameter, whereas the grinder pump only requires a 1 to do the same job. The grinder pump discharges at a low volume, but it can do this for a very long distance. Grinder pumps can also pump waste to very high altitudes, in upwards of 200, unlike the sewer ejector pump.
