Recommission new, repaired or stagnant plumbing with a plan suited to the system, water source and local requirements.
JAUNE / YELLOW
Long stagnation, new piping or major work: plan systematic flushing and, where required, testing or disinfection.
ROUGE / RED
Federal large-building durations/protocols are not a universal home recipe; adapt to system and authority.
Construction triage
