A sewage ejector receiving the discharge of a water closet must have a discharge pipe of not less than what diameter and be able to pass a 2-inch solid?

A pump or ejector handling water-closet discharge must have a discharge pipe of at least 2 inches and be capable of passing a 2-inch spherical solid. This prevents clogging by the solids typical of sanitary sewage. Smaller effluent-only pumps are permitted only where they handle liquid waste without solids.
