What condition must plumbing installations NOT create?

Plumbing installations must not create unsanitary conditions or a nuisance because such situations can pose serious health risks to the public and practitioners within a cosmetology setting. Maintaining sanitary conditions is crucial in any beauty service environment to prevent the spread of bacteria and infections that could arise from improperly managed plumbing systems. When plumbing creates unsanitary conditions, it undermines the hygiene standards necessary for safe cosmetic procedures.

Inadequate water supply, obstructed sewage flow, and excessive drainage problems are serious issues, but they primarily affect the functionality of the plumbing system rather than directly impacting health and safety. The potential for public health hazards stemming from unsanitary conditions surpasses these other concerns, as they can lead to unsafe environments overall.
