What is a recommended practice for ensuring the integrity of potable water lines during installation?

Testing pressure after installation is a crucial practice in ensuring the integrity of potable water lines. This process, known as pressure testing, verifies that the installed plumbing system can withstand operating pressures without leaking. It typically involves filling the system with water and applying a specified pressure for a predetermined duration. During this test, any weaknesses or potential points of failure in the joints, fittings, or pipes can be identified and corrected before the system is put into service.

Proper pressure testing is essential because it helps ensure that all components have been installed correctly and that there are no leaks, which can compromise both the function of the system and the safety of the drinking water. Ensuring that the water lines can handle pressures beyond normal operating conditions also adds an extra layer of reliability to the plumbing installation.
