01
Current notice
Open the current Town resource rather than relying on a saved or dated announcement.
Sheet 42 / Diagnostic set
Compare the current notice with the tap observation
Compare hot-cold, fixtures, timing, flushing notice, and current official direction without making safety claims.
Changed color or clarity after public work or flushing should be described by fixture, hot-cold side, start time, duration, and the current Town message. Appearance alone does not decide cause or safety.
