Stay away from unsafe water and electricity. Use a household shutoff only when you already know its operation and can reach it safely; then arrange the source assessment and any drying separately.
Keep personal safety ahead of diagnosis
Do not touch energized equipment, enter contaminated water or climb into an unsafe space to obtain a photograph. Use appropriate emergency services for immediate danger. A website checklist cannot determine whether a particular wet area is safe. Tell the assessing business about known electrical or contamination concerns before access is attempted.
Use only familiar controls
A safely reachable, familiar household water shutoff may limit escape. Do not force a seized valve, operate utility equipment or adjust gas controls based on this article. If the control is unclear, describe the situation and use the responsible utility or qualified assistance. Record what was isolated and whether water continued.
Keep evidence useful and simple
From a safe position, note the wet area, whether it appears during fixture use and whether other rooms are affected. Accessible equipment information can help. Avoid turning observations into a diagnosis: a ceiling stain does not identify the exact pipe or connection above it.
Plan repair and drying separately
Ask how the source will be located, what access is needed and how the repair will be tested. Drying, damaged finishes and restoration may require a separate scope or trade. In a shared building, contact the manager about authorization and other units before approving an interruption.
Seattle-area preparation
Use the supplier on your bill and the full street address to identify the correct utility and permit jurisdiction. For shared buildings, establish authorization and equipment access. Washington L&I has different plumbing qualification scopes; verify the business and the person who will perform the requested work rather than assuming qualifications from a service-page label.
Choose a safe next step
Water near electricity, sewage or unsafe access?
Keep people clear. Do not touch powered equipment or enter hazardous water. Contact appropriate emergency or utility help for immediate danger.
Familiar shutoff safely accessible?
Use it only if you already know its operation and can reach it safely. Do not force a valve or operate a gas valve based on this guide.
Water stopped or source uncertain?
Record the observed area and timing. Ask for investigation, source repair and drying scopes separately. A dry surface does not prove concealed materials are dry.
