Separate public-water compliance from premise materials

DECISION GUIDE 39

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

Review city and property records, visible service entry and plumbing history, and any current Santa Rosa or state instructions. Use an accredited laboratory and an appropriate sampling plan when testing.

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

Do not identify pipe material from color alone or rely on an instant home strip for a final decision. Follow current public-health advice for use and sampling.

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

A proposal should state the verified material or result, exact affected section, sampling or replacement scope, permit and utility roles, restoration, flushing, and confirmation.

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.
