Read the pattern
Dry reachable surfaces and compare idle, cold flow, hot flow, drainage, and appliance operation. Note the highest first wet point, rooms above and below, recent work, and whether the moisture continues after use stops.
Decision terrace 03
Move from evidence to a bounded authorization
Hold the safety line
Stay out of wet power and away from sagging finishes. Turn only a known private fixture stop or building control that moves normally; extra force during active leakage can create a second failure.
Place the Seattle boundary
Public street leakage or meter-side questions belong with SPU. Private piping, fixture, and drain investigation may overlap drying, electrical clearance, cabinetry, and finish work that requires separate authorization.
Write the visit
Require the suspected source, diagnostic step, access side, protection, repair endpoints, test, debris handling, and restoration exclusions in writing. Facts behind a closed surface should remain labeled as assumptions.
Keep the closing evidence
Repeat the exact safe condition that produced water, inspect disturbed joints during and after use, and record remaining damp materials. A dry moment alone is not a complete closeout.
