I do not think you understand what I am asking you about.
The pipes were laid in the ground early in the build. They should have all been caped, tied together and pressurized with a pressure gauge showing that pressure was maintained. This lets any leaks be identified before the pipes are buried under dirt, gunite, and decking. It also lets you see if and trades damaged a pipe during their work.
Once almost all the other work is done, and the pipes still holding pressure, then the pipes are uncapped and equipment installed.
This is different then any building inspections. The inspector does not care if your pipes will leak.
