Why are pressure tests important for plumbing systems?

Pressure tests are crucial for plumbing systems primarily because they serve as an effective means of identifying leaks that may not be immediately visible. When a plumbing system is subjected to a pressure test, water pressure is increased within the pipes, allowing inspectors to scrutinize the system for any drops in pressure that could indicate the presence of leaks. Such leaks can occur in joints, fittings, or other areas that might be hidden from sight, leading to potential water damage, mold growth, or structural issues if left undetected.

By conducting these tests, inspectors can ensure the integrity of the plumbing system before it becomes operational, thereby providing good assurance to homeowners that excessive water loss will not occur. This proactive measure is essential in maintaining a reliable and efficient plumbing system, which emphasizes the importance of this procedure over simply measuring flow rates, evaluating water quality, or determining the age of the plumbing system.
