How do you fix a toilet that keeps flushing intermittently?

To fix a toilet that keeps flushing intermittently, first, check the flapper valve at the bottom of the tank; it may be worn or not sealing properly, requiring replacement. Ensure the chain connected to the flapper isn't too tight or tangled, as this can prevent it from closing completely. Additionally, inspect the fill valve for any debris or wear, and adjust the water level if it's too high, causing overflow into the overflow tube. If these steps don't resolve the issue, consider seeking professional Plumbing assistance.
