Verify Water Pressure and Purge Air

What happens here

Begin by holding the pressure testing tool securely, ensuring it is properly connected to the pipe system being tested. The video implies that an initial air pressure test has likely been conducted to check for leaks, and now the system is being transitioned to water pressure. The individual then activates a mechanism, likely a valve or lever on the pressure testing tool, to release the pressure. Initially, a significant amount of air, which was used for the air pressure test, is forcefully expelled from the pipe. This is quickly followed by a strong, high-pressure stream of water, confirming that the pipe system is holding water pressure effectively and that any trapped air has been successfully purged. The forceful expulsion of water also serves as a final visual confirmation of the pipe's integrity and its ability to withstand operational water pressure.

Goal: Activate the valve on the pressure testing assembly to release residual air and confirm robust water flow, indicating successful pipe pressure integrity.
