Read the pattern
List automatic devices, record display units and timestamps, pause ordinary consumption for a planned interval, and repeat under similar conditions. Photograph from outside the equipment boundary.
Decision terrace 09
Move from evidence to a bounded authorization
Hold the safety line
Never open, adjust, bypass, or break a utility seal. Plan around occupied-building and life-safety needs before isolating branches or pausing essential equipment.
Place the Seattle boundary
Meter and public service questions belong with SPU. A private plumber can use the observation to design staged fixture and branch isolation without claiming control of utility hardware.
Write the visit
Ask the provider to state each isolation step, what it can eliminate, what remains active, the expected duration, and how results will be logged before intrusive work begins.
Keep the closing evidence
Repeat the same interval after the suspected repair with every active device noted. Continued movement is a finding to investigate, not a reason to declare success from sound alone.
