Preserve the useful detail
Note tank level, refill timing, overflow behavior, local stop condition, floor moisture, and whether the bowl changes without a flush.
The decision on display
Do not transfer the hazard
Close a sound stop for uncontrolled fill. A downstream backup is a separate hazard and should not be tested by flushing.
Make the proposed work comparable
Name fill, flush, supply, stop, tank, seal, flange, floor, quiet-hold, exterior-leak, and repeated-flush checks.
