Decide whether the blockage is in the bowl or beyond it

DECISION GUIDE 25

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

Stop after one failed flush. Check the bowl level, tank fill, other bathroom drains, and whether another fixture makes the bowl move or gurgle.

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

Close a sound toilet stop if water keeps filling, protect the floor, and avoid plunging when sewage is returning from a shared drain.

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

Ask whether the scope covers bowl clearing, toilet removal, seal replacement, branch access, camera work, reset, exterior leak check, and repeated flush test.

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.
