A toilet can suddenly overflow due to two primary reasons: a severe blockage in the trapway caused by excessive paper or non-flushable items where someone attempted a flush without realizing it was clogged, or a mechanical failure in the fill valve system where the float gets stuck and continuously pumps water into the tank and bowl until it spills over the ceramic rim. Callout type="warning" title="Hygiene Warning": Wear rubber gloves and shut off the wall water supply valve immediately. Verification: Inspect whether the bowl is blocked by waste or if the fill valve is running uncontrollably.
