Why might code improvements be necessary?

Building code requirements that are in place to protect the health and welfare of buildings, structures, and the public and can change over time.

Answer

When new plumbing work is performed, the licensed plumber is required to perform the work in accordance with current code requirements. Particularly in the case of replacement of old equipment.  All code improvements are often required by applicable state and local governing agencies and are developed with the intent of protecting you.

Many times, it’s necessary to perform code improvements because previous work may have been performed by an unlicensed individual who did not consult with the local safety regulations.
