What is the UPC regulation regarding pressure testing of new systems?

Pressure testing is a critical requirement for new plumbing systems under the Uniform Plumbing Code (UPC) to ensure they are free from leaks before being put into service. This regulation is in place to safeguard against potential water damage, contamination, and to ensure the overall integrity of the plumbing system.

By requiring pressure testing, inspectors can verify that all joints, connections, and materials are functioning as intended and that the system can withstand the operating pressures it will encounter during normal use. This proactive measure prevents issues such as water waste, environmental damage, and costly repairs later on.

Testing for only aesthetic leaks or after installation could leave significant risks unaddressed, which is why UPC mandates comprehensive pressure testing immediately following the installation of new systems. Thus, ensuring every part is assessed for functionality before it is concealed or used is a fundamental aspect of maintaining plumbing safety and performance.
