A broad flow change needs several safe observations before it can be called property-wide. Separate cold, hot, exterior, upper-level, and lower-level results.

Check current SPU outage information and any building notice. Cold weather, public work, or peak use can be relevant timing without proving the cause.
Choose a few representative outlets and note whether the condition began suddenly or gradually. Stop comparisons that create overflow, leaks, or unsafe temperature.
In multifamily property, ask management what the building serves and whether other units report the same change. Preserve each report under its source.
What to observe now
Keep the notes factual. A visible clue can direct an inspection without proving what is hidden.
List changed and ordinary outlets rather than saying everything is affected.
Compare upper and lower floors only where access and use remain safe.
Keep supply-side observations separate at representative fixtures.
Record whether the flow changes by hour, simultaneous use, or recent event.
Attach the current outage or utility response without assigning a private cause.
Responsibility
Closeout record
The provider or utility record should state measurements, supported boundary, work performed, outlets demonstrated, public coordination, and the follow-up trigger.
