Final Water System Test

What happens here

After all plumbing installations are complete, the main water supply to the house is turned back on (from the outdoor meter box). The installer then carefully inspects all new drain and PEX water line connections for any signs of leaks. The system is confirmed to be watertight and functioning correctly, indicating a successful plumbing installation. The presenter expresses relief that no leaks are found.

Goal: The main water supply is turned back on to the house, and all new plumbing connections are thoroughly checked for any leaks to ensure a fully functional and watertight system.
