Turn indirect leak clues into a testable brief

DECISION GUIDE 04

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

Build a timeline that connects fixture use, automatic equipment, meter movement, moisture, sound, and shutoff response. Ask how each locating tool will confirm the next step.

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

Run only controlled tests that will not worsen damage. Preserve photographs and avoid destructive access until isolation evidence narrows the area.

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

Price locating separately from opening, repair, drying, and restoration. Require confidence, limits, and a post-repair test in writing.

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.
