Who is responsible for pressure testing a piping system?

The responsibility for pressure testing a piping system lies with the installer. This is because the installer is the person who has the training and knowledge to properly conduct the pressure test, ensuring that the system is leak-free and safe for operation. During the installation process, the installer is required to follow specific guidelines and regulations that dictate how to properly pressure test the system, which typically involves applying compressed gas or liquid to see if it maintains the designated pressure over a specific period of time.

Pressure testing is a critical step in confirming that the installation has been completed correctly and that there are no leaks that could pose safety risks. The installer is also in the best position to assess the physical integrity of the piping system, as they have firsthand experience with its construction and assembly. While inspectors may verify the results of the pressure test later on, the primary duty of conducting the test itself is assigned to the installer.
