What is the primary reason for using pressure testing on plumbing systems?

The primary reason for using pressure testing on plumbing systems is to check for leaks. Pressure testing involves filling the plumbing system with water or air, then applying pressure to see if it holds steady over time. If there is a drop in pressure, it indicates that there is a leak somewhere in the system. Detecting leaks is crucial because they can lead to water wastage, structural damage, and mold growth if not addressed promptly.

While checking for clogs or ensuring proper drainage is essential in maintaining a plumbing system, pressure testing specifically focuses on the integrity of the pipes and joints that might be compromised. Measuring water temperature is unrelated to the purpose of pressure testing, as it does not provide information about the physical condition of the plumbing infrastructure. Therefore, the practice of pressure testing is primarily aimed at identifying and addressing leaks to ensure the reliability and safety of the plumbing system.
