Public toilet facilities must be maintained in accordance with the International Plumbing Code because this code specifically addresses the design, installation, maintenance, and inspection of plumbing systems, which include sanitation facilities like restrooms. The International Plumbing Code sets the standards for ensuring the health and safety of the public by regulating water supply and waste disposal, thereby ensuring that public toilets are functional, sanitary, and accessible.
The focus of the International Plumbing Code on various aspects pertinent to plumbing systems includes the materials used, proper installation methods, ventilation, and accessibility standards for users. Adherence to this code helps to prevent public health issues related to sanitation and ensures a safe environment for all users of public restroom facilities.
