Moving water
Use the active-water sheet when the wet edge is growing or newly visible.
Sheet 02 / Diagnostic set
Choose the branch that matches the evidence
Select a guide by water movement, drainage, flow, temperature, sound, use, or public notice.
The index sorts by moving water, drainage, flow, temperature, sound, usage, and official notices. Those are observation branches, not diagnoses.

Five callouts for this drawing
Each note describes an action, not a diagnosis. Leave unsupported branches open.
02
Drainage
Count affected fixtures and record the lowest change before testing more.
03
Flow
Compare hot and cold at a few representative outlets without removing parts.
04
Temperature
Stop unsafe checks and note valve position, duration, and simultaneous use.
05
Usage or notice
Preserve the exact alert, bill period, meter note, or Town message.
Trace the source
Follow evidence through the branch
Pick the narrowest branch that fits, carry over the location and time, and add another branch only when a second symptom actually appears. This keeps a single-fixture problem from becoming an unsupported whole-system claim.
Repair route and access map
Define the boundary before authorization
After inspection, annotate the branch with the supported finding and archive routes that were checked and ruled out. Keep unknown or inaccessible areas visibly unresolved.
