Which statement correctly pairs discharge sizes with the type of ejector?

Which statement correctly pairs discharge sizes with the type of ejector?

• A. Grinder: 1-1/4 inches; Non-grinder: 2 inches
• B. Grinder: 2 inches; Non-grinder: 1-1/4 inches
• C. Grinder: 3 inches; Non-grinder: 2 inches
• D. Grinder: 1-1/2 inches; Non-grinder: 2-1/4 inches

Answer: (A)

Discharge size is tied to how solids are handled by the ejector. A grinder ejector chops solids into a slurry, which lets wastewater move through a smaller-diameter discharge line—typically 1-1/4 inches. A non-grinder ejector doesn’t grind solids, so the system relies on a larger discharge to handle solids and maintain flow without clogging, commonly 2 inches. This pairing reflects standard practice for residential ejector systems, balancing solids handling and flow capacity. Using a grinder with a larger 2-inch discharge would be more than needed, while a non-grinder with a 1-1/4-inch discharge could lead to frequent clogs and inadequate flow.
