Contain visible water and keep the source clues

DECISION GUIDE 03

Make the next action fit the evidence

Use the condition described here to narrow the first safe action, the responsible contact, and the written authorization.

Do not pay for certainty that the observable pattern does not support.

OBSERVE

Preserve the useful clues

Dry accessible surfaces, observe the first wet point, and compare the result after a fixture stop or house valve is closed. Note warm water and nearby appliance cycles.

Write the time, fixture, room, and use that preceded the change.
Photograph the wider context before taking a detail view.
Keep model labels, bills, prior repair records, and test results together.

CONTAIN

Choose the safe boundary

Use a container only when there is no sewage, hot-water, electrical, or unstable-material hazard. Do not force corroded valves or open finished walls.

Containment should reduce harm without erasing evidence or transferring risk to gas, electricity, wastewater, finishes, or utility equipment.

AUTHORIZE

Put the first scope in writing

Separate pipe repair, access, material drying, cabinet or wall removal, testing, and finish restoration. Require a leak check before closure.

Ask what is included, excluded, and still unknown.
Set the price or authorization boundary before work expands.
Define the test or record that will show completion.
