holds water

Withstands logical scrutiny

To hold water is to be logically sound or able to withstand scrutiny.

An argument, theory, or excuse either holds water or doesn't: Her alibi doesn't hold water.

The metaphor comes from containers—if a vessel leaks, it fails its purpose.

Similarly, a flawed argument fails to contain its logic.
