The Kentucky Plumbing Code Committee voted to amend the Kentucky Plumbing Code, removing a requirement to use cast-iron piping in buildings over 45 feet in height. It would open the door for developers in Louisville to use PVC piping on taller developments.
The change must be reviewed by the Board of the Department of Housing, Buildings and Construction. Developers said this change represents a significant step forward as Kentucky is one only a handful of states that still have their own plumbing codes.
Unlike Kentucky, most states have adopted the International Plumbing Code, which has become an industry standard.
