What code governs the connections to appliances regarding potable water supply?

The International Plumbing Code is the governing document that specifically addresses the standards and regulations for plumbing systems, including connections to appliances in relation to potable water supply. This code ensures that all plumbing installations, alterations, and replacements adhere to safety and sanitary standards to protect public health and the environment.

The code outlines requirements for the construction and maintenance of potable water systems, which includes the proper connections to appliances that utilize potable water. This encompasses water heaters, dishwashers, and other fixtures, ensuring that the installations not only function correctly but also minimize the risk of contamination.

Other codes listed, such as the National Electric Code, focus on electrical installations and safety but do not address plumbing systems. The International Fire Code primarily relates to fire safety measures and prevention, while the Uniform Mechanical Code governs mechanical systems, which may indirectly address plumbing but does not specifically focus on potable water connections to appliances like the International Plumbing Code does.
