The IRC does not address sump pumps very well. The IPC does and the definitions is the key to what the following says.
From the 2006 IPC. (red, underlining and bold are mine)
-
712.3.5 Ejector connection to the drainage system. Pumps connected to the drainage system shall connect to the building sewer or shall connect to a wye fitting in the building drain a minimum of 10 feet (3048 mm) from the base of any soil stack, waste stack or fixture drain. Where the discharge line connects into horizontal drainage piping, the connector shall be made through a wye fitting into the top of the drainage piping.
- BUILDING SEWER. That part of the drainage system that extends from the end of the building drain and conveys the discharge to a public sewer, private sewer, individual sewage disposal system or other point of disposal.
- - Combined. A building sewer that conveys both sewage and storm water or other drainage.
- - Sanitary. A building sewer that conveys sewage only.
- - Storm. A building sewer that conveys storm water or other drainage, but not sewage.
- BUILDING DRAIN. That part of the lowest piping of a drainage system that receives the discharge from soil, waste and other drainage pipes inside and that extends 30 inches (762 mm) in developed length of pipe beyond the exterior walls of the building and conveys the drainage to the building sewer.
- - Combined. A building drain that conveys both sewage and storm water or other drainage.
- - Sanitary. A building drain that conveys sewage only.
- - Storm. A building drain that conveys storm water or other drainage, but not sewage.
