North Seattle plumbing / guide 39
A taste or odor report needs a careful source description. Smell near a drain, odor in cold water, odor in hot water, and an issue at one fixture are not the same observation.

SPU publishes water-aesthetics guidance and tracks reported taste and odor concerns. Current utility direction should control any safety or flushing decision.
Use a safe observation only if public guidance allows it. Record hot or cold side, first draw or continuous flow, fixture spread, building reports, and whether the odor remains when the water is away from the drain.
Do not diagnose bacteria, mold, chemicals, gas, contamination, or heater failure from a description. Leave testing and safety determinations to qualified authorities.
What to observe now
Keep the notes factual. A visible clue can direct an inspection without proving what is hidden.
Note whether the condition appears on the first draw or continues during ordinary flow.
Keep heater-related observations distinct and avoid unsafe temperature exposure.
Describe an odor near the opening without mixing cleaners or opening piping.
Ask whether another fixture or unit reports the same issue.
Use current utility information for persistent, widespread, or urgent water concerns.
Responsibility
Closeout record
Save the utility reference, provider finding, sample or test instruction, work performed, product details, and official next step under the correct issuer.

Public procedures and status can change. Use the source that owns the decision.
