Use the city dye check to find a silent toilet leak

DECISION GUIDE 11

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

Also note whether water runs into the overflow, the tank refills by itself, the handle binds, or water appears at the floor. Those clues identify different paths.

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

Follow the fixture maker for unusual tanks. Close a sound local stop if water is uncontrolled and do not confuse an internal leak with a sewer clog.

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

Name fill, flush, supply, tank, seal, and floor conditions separately. Require a full refill, quiet hold, flush, and exterior leak check.

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.
