Confirm the service map
Use reliable valve schedules, plans, tags, and building staff knowledge, then have the qualified party verify the control. Identify units, floors, commercial uses, equipment, hot-water or recirculation systems, and sensitive occupants in the affected zone. Do not exercise an uncertain valve as a casual test.
Write the interruption plan
Set notice time, work window, authorized operator, upstream backup, drain point, containment, expected duration, communication contact, and decision rule if a valve will not hold. Consider sanitation, accessibility, food service, equipment, and occupied-space needs. A marketing estimate of downtime is not a substitute for a building-approved plan.
Restore service methodically
The responsible professional should control refill, watch repaired and accessible joints, release air as appropriate, check representative fixtures by zone, and return equipment or controls within the agreed scope. Occupants need a clear all-clear and a route to report remaining air, color, pressure, leakage, or fixture problems.
Update labels after proof
Record every operated valve, actual served area observed during the interruption, normal position, failure or leakage, repair, and test. Correct the property valve map only to the extent confirmed. A tag based on assumption can create a larger future incident, so unknown branches should remain explicitly unknown.
