Ejector Pump
An ejector pump is a special type of pump used in plumbing systems to move wastewater from lower levels to higher levels, typically in basements or areas below the main sewer line. Think of it as an "elevator for water" that helps prevent flooding and ensures proper drainage. Plumbers install and maintain these pumps in homes and buildings where natural drainage isn't possible because of the location or layout. Similar devices include sump pumps and sewage pumps. These are essential tools in a plumber's work, especially when dealing with basement plumbing or below-grade installations.
