Running, Leaking or Unstable Toilet?
A toilet that runs continuously can have an internal tank-component problem, while water at the base may indicate a seal or flange issue.
Movement at the floor should also be taken seriously. Tightening bolts cannot reliably correct a damaged flange or soft flooring below the fixture.
A tank that refills on its own, a rocking bowl and water at the base each point to different repair areas. Describing the exact symptom helps avoid replacing internal parts when the real issue is the floor connection or drain interface.
Rough-In, Flange and Floor Conditions
Replacement toilets need to match the existing rough-in and fit the available space. The flange should be secure and the surrounding floor stable enough to support the new fixture.
If the floor is damaged from a long-term leak, that repair should happen before the replacement toilet is treated as the finished solution.
Fixture Repair vs Drain-Line Problem
Tank components, seats and accessible seals may remain within fixture-level repair. A recurring backup or slow drain can indicate a drain-line problem beyond the toilet itself.
Those plumbing conditions require appropriate qualified diagnosis. Bathroom Remodeling is also separate when the toilet is one element of a larger layout or accessibility project.
