2018 International Plumbing Code

A modification to Section 703.4 (Reuse of Buried Drain and Sewer Piping) states that the use of existing building sewers and existing building drains for new building plumbing system is clarified.

“Testing” of old, existing buried building drains or building sewers might not ever be successful, eliminating the possibility for their reuse. As such piping is non-pressurized gravity flow, a test means very little. What is important is a visual, internal examination (typically by video camera equipment) to make sure that the piping is viable for reuse. This is especially beneficial where the piping would be difficult to replace, such as where it crosses under parking lots and streets.
