VERT / GREEN
Install simple detectors at risk points and test them per manufacturer guidance.
Water leak detection and automatic shutoff
Place sensors at meaningful risks, distinguish alarms from a main shutoff valve, test regularly and plan behaviour during power/network outages.
JAUNE / YELLOW
An automatic valve can reduce damage but does not diagnose the leak cause.
ROUGE / RED
Motorized main shutoff, plumbing modification or system without manual override: professional installation.
Interactive triage
This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.
