Test New Plumbing System

What happens here

With all plumbing lines installed and connections secured, the main water supply to the house is carefully turned back on. The presenter then systematically inspects every connection point for both the drain and water supply lines, checking for any signs of leaks. Having a bucket or small container handy for potential spills from opening cut lines is recommended. After a thorough inspection and confirmation of no leaks, the new plumbing system is deemed successfully installed.

Goal: Turn the main water supply back on and meticulously check all new connections for any leaks to ensure the system is fully watertight.
