A useful plan distinguishes the location of a component from permission to use it.
DOWNTOWN SEATTLE / GUIDE
Building Water Shutoff Plan
Record accessible labels, served areas, responsible contact, notice needs, shutdown window, restart checks, and last qualified service.
PRACTICAL GUIDE
Map valves without operating them
Document unit, branch, riser, zone, equipment, and service shutoff authority without operating uncertain valves.
Do not force valves or operate common or public hardware as a test.
Plan notification and restoration
Use labels, drawings, prior work, and authorized staff knowledge to distinguish fixture, unit, branch, riser, zone, building, fire, irrigation, and utility controls. Mark every uncertain valve as unverified, and decide how service will be checked after an authorized shutdown ends.
Revise the plan after piping, valves, tenants, zones, or management procedures change.
