Record Where Water Appears Before Naming the Source

Stay clear of standing water near electrical panels, outlets, appliances or damaged wiring. Do not enter a flooded crawlspace, unstable excavation or area with suspected sewage or other contamination. If water is rising, the building appears unsafe or an electrical hazard may be present, use the appropriate emergency and professional channels before continuing documentation. From a safe location, record the time, room and immediate protective action. Photograph original conditions only when doing so does not delay necessary safety, loss-prevention or cleanup work.

Avoid electrical and structural hazards

Do not enter open excavations or unsafe crawlspaces

Record urgent actions without delaying them

Write down when the symptom began, how long it lasted and whether it followed intense rain, several wet days, irrigation, fixture use, an appliance event or ordinary dry weather. Add whether the area dried before the next occurrence. Victoria explains that heavy rain can saturate soils and contribute to flooding, but weather timing does not identify a private-property source. Keep rainfall, plumbing use and sump behaviour as separate dated entries. Repeated observations are more useful than a single memory, and uncertainty should remain visible rather than being converted into a diagnosis.

Record start, duration and recurrence

Separate rain from plumbing events

Keep one-time and repeated patterns distinct

Mark the visible condition on a simple floor plan. Note whether water or staining appeared at a wall-floor joint, through a crack, around a penetration, below a window, beneath a fixture or across a slab area. Record height, spread, colour and odour without touching unknown material. Finished surfaces can conceal the route water travelled, so describe the observation instead of naming its cause. Take photographs from repeatable positions and label each by room, wall direction and date. Include unaffected areas when they help define the visible boundary.

Label the room and wall direction

Record height and spread

Describe evidence without declaring a cause

Note recent fixture use, supply leaks, drain backups, appliance operation and repair history near the affected area. From safe exterior ground, also record downspout endpoints, grading, visible pooling, window wells, accessible cleanouts and nearby street-drain conditions. Do not open walls, change pump settings, enter the street or dig to expose pipe. A plumbing event, surface-water pathway and perimeter drainage concern can require different evidence. Keep each possibility in its own section and attach any qualified findings already available rather than treating location alone as proof.

Log nearby fixture and appliance events

Photograph accessible exterior flow paths

Keep source categories separate

If the property has an accessible sump, note visible water level, pump cycles, alarms and any documented discharge route without bypassing controls or removing covers not intended for routine access. Record backup-power information only when supported by current equipment records. For a gravity outlet, retain plans, inspection notes or footage showing the route if they exist. A pump that is quiet during one visit does not prove performance during a storm, and a visible pipe does not establish a lawful or functional connection. Mark outlet status as confirmed, reported or unknown.

Record cycles and alarms without changing settings

Keep pump and service records

Mark an unknown outlet as unresolved

Victoria's flood-prevention information addresses street drains and public flooding reports. Its stormwater pages explain that storm drains carry runoff toward receiving waters and that only clean water belongs in the system. These facts help frame environmental and public-system questions, but they do not show the route or condition of a private perimeter drain. Record public catch-basin issues separately from the building symptom and use the City contact route where a street drain is blocked or flooding is uncertain. Do not lift grates or assume a private discharge connection.

Separate street-drain observations

Keep contaminants out of storm drains

Do not infer the private connection

Combine the timeline, floor plan, photos, plumbing records, sump notes, exterior observations and available drainage documents in one dated file. List the questions a site investigation must answer: plausible source categories, accessible drain segments, pipe or access uncertainty, outlet evidence and limits of the proposed method. Continue with the older-system, inspection, access, replacement and permit-and-quote pages before authorizing construction. The brief should help qualified reviewers focus their work; it cannot promise a dry basement, establish concealed conditions or replace assessment of an active hazard.

List known facts and unresolved questions

Give every estimator the same record

Keep guarantees and remote conclusions out
