Notice the signs
Observe
List every automatic use, note meter units and timestamps, pause ordinary consumption for a short planned interval, and repeat under similar conditions. Preserve photos of the display without touching seals or covers.
Note 12
Place the condition before choosing the work
Protect the room
Safety line
Do not manipulate utility equipment or create an unsafe outage. Homes with life-safety, medical, heating, treatment, or occupancy needs require an appropriate isolation plan rather than an improvised whole-building test.
Material note
Local boundary
Meter ownership and interpretation belong with the verified water provider. Cohasset Water rules reserve meter installation and removal to department personnel or representatives, so private work must stop at that boundary.
Service flow
Written scope
Give a plumber the recorded intervals and known automatic cycles. Ask for a staged isolation plan that identifies which branch or fixture each step can eliminate, what will remain in service, and how the result will be documented.
Close the loop
Verification
A useful follow-up repeats the same interval after the suspected repair and records every active device. If movement remains, preserve the finding instead of declaring success from a quieter sound or a single glance.
