A toilet that runs constantly can waste a large amount of water a day and usually traces back to a worn flapper or a fill valve that will not shut off. A toilet that rocks against the floor is often a failing wax seal, which lets water reach the subfloor underneath. A toilet that clogs no matter what goes into it may point to a problem further down the line rather than the fixture itself.
If a toilet is actively overflowing, shut off the small valve behind the base at the wall, or shut the main water supply if that valve is stuck or missing.
A base that feels soft, a toilet that rocks, or repeated clogging on an otherwise clear line are reasons to call rather than keep plunging.
