What Is a Sewer Grinder Pump

A grinder pump works like a garbage disposal – it grinds up wastewater from a home (i.e. toilet, shower, washing machine) and pumps it into the public sewer system. … A grinder pump will normally run for one or two minutes and automatically turn off when the wastewater in the tank reaches the preset off level.

Why do I need a sewage grinder pump?

A grinder pump is designed to aid homes that are located lower than the nearest municipal sewer line. The standard home is built higher than the sewer line so that gravity will draw wastewater from the sewage system. Not all homes are in this position, and for those homes, it’s necessary to have a grinder pump.

How much does a grinder pump cost to replace?

The average cost for installing the grinder pump is approximately $4,000-$5,000, but varies per property. The cost for electricity to the grinder pump is similar to that of a 40-watt light bulb, which is about $15 to $20 per year. This is in addition to the connection fee of $2,530.
