01
Pool depth
Use ordinary water only and stop before the basin nears overflow.
Sheet 28 / Diagnostic set
Measure one drain before expanding the route
Time pooling and clearing at one fixture and disclose prior product or tool use.
Record the pooling height and approximate clearing time during ordinary use, then stop before overflow. A single slow fixture does not automatically describe the building drain.

03
Stopper position
Record normal open and closed behavior without dismantling the assembly.

Neighbor check
Note whether one nearby drain changes during the same safe interval.
05
Treatment history
Disclose cleaners, plungers, snakes, or prior service before work begins.
Trace the source
Follow evidence through the branch
Add stopper position, visible debris, nearby fixture behavior, prior products or tools, recurrence, and last normal use. Ask what evidence would justify moving beyond the fixture branch.
Repair route and access map
Define the boundary before authorization
Retain the access point, cleaned or replaced part, removed material description, flow demonstration, product cautions, and instructions for a repeat symptom.
