Read the pattern
Observe with controls off, under cold and hot flow, during directed spray at each enclosure edge, and after drainage. Note loose trim, temperature shifts, recent finish work, and access behind the valve.
Decision terrace 19
Move from evidence to a bounded authorization
Hold the safety line
Stop use for scalding, unstable flooring, ceiling movement, or water near power. Do not remove tile until supply, drain, and enclosure tests have a planned order.
Place the Seattle boundary
Plumbing, glass or enclosure sealing, tile waterproofing, structure, electrical clearance, drying, and finish repair can be separate scopes under Seattle permitting.
Write the visit
Define cartridge, valve, diverter, arm, drain, waterproofing limit, access side, trim reuse, test method, wall opening, and restoration responsibility.
Keep the closing evidence
Repeat staged tests rather than wetting every surface together. Inspect the area below and record what must dry before a finish is closed.
