What must be ensured if plumbing work requires cutting or altering a wall?

When plumbing work involves cutting or altering a wall, it is essential to ensure that all plumbing is up to code in the new configuration. This is crucial because plumbing codes are established to ensure safety, health, and legal compliance for building systems. These codes dictate the proper installation, maintenance, and alteration of plumbing systems to prevent issues such as leaks, drainage problems, and other hazards that could affect the integrity of the property and the health of its occupants.

By adhering to plumbing codes, the newly configured plumbing system will not only function efficiently but also reduce the risk of future repairs or issues arising from improper installation. In essence, confirming that the plumbing is up to code represents a commitment to quality and safety in the construction process, safeguarding both the property and its inhabitants.
