01
Affected outlet
Describe stream width, direction, pulsing, and the control position used.
Sheet 20 / Diagnostic set
Keep a one-room flow problem in one room
Map flow across fixtures in one room before expanding the suspected scope.
Compare the affected outlet with neighboring fixtures in the same room. A faucet aerator, shower outlet, hot-side branch, or room supply may present differently, and no generic page can decide which applies.

Five callouts for this drawing
Each note describes an action, not a diagnosis. Leave unsupported branches open.
02
Neighbor comparison
Use another safe fixture in the room to test whether the change is shared.
03
Hot-cold split
Log each side separately so the diagram does not merge two systems.
04
Recent fixture work
Attach model, part, and installation information when available.
05
Measurement request
Ask the provider to show the evidence behind a local or upstream finding.
Trace the source
Follow evidence through the branch
Record hot and cold separately, valve position, normal simultaneous use, recent fixture work, and any visible debris or change. Have the plumber measure before proposing a broader system scope.
Repair route and access map
Define the boundary before authorization
The visit record should name the fixture or branch inspected, parts removed or replaced, measurements, post-work flow, and nearby outlets not included.
