The float

The ball rises to stop water from flowing into the tank. However, if it’s not reaching the correct height, water will continue flowing and cause leakage.

If your toilet assembly is loose, it’s hard to miss the leaking spot (s). Tighten the loose connections using an adjustable wrench until the nuts and bolts are tight.
