What must water from an individual water supply be approved as before connection to the plumbing system?

Water from an individual water supply must be approved as potable before it can be connected to the plumbing system. Potable water is defined as water that is safe for human consumption, meaning it meets health and safety standards set by regulatory agencies. The plumbing code emphasizes the importance of using water that is clean and suitable for drinking, cooking, and other domestic uses, to protect public health and ensure the safety of the plumbing system.

In general, non-potable water is unsuitable for drinking and can contain contaminants that pose health risks. Contaminated water does not meet safety standards and should not be used for any purpose that could lead to human exposure. Untested water lacks verification of its quality and safety, posing potential risks if used without proper assessment. Therefore, confirming that the water is potable is essential for safe plumbing practices and compliance with the plumbing code.
