What must every salon ensure about its plumbing?

Every salon must ensure that its plumbing complies with the state and local plumbing code because these regulations are in place to protect the health, safety, and welfare of the public. Compliance with plumbing codes ensures that water supply systems and waste disposal systems are functioning correctly and sanitary. This is especially important in a salon setting where services often involve water usage, such as washing hair or cleaning equipment. Adhering to the plumbing code helps prevent issues like leaks, water contamination, or backflow, which could severely impact the salon's operation and its clients' health.

Other choices, while they may seem appealing or aesthetically pleasing, do not address the critical regulatory requirements necessary for safe and compliant salon operations. The focus must always be on health and safety standards mandated by local authorities.
