The determining factor isn't whether water caused the damage, it's what set the water in motion. Insurers classify water events as sudden or gradual, and only sudden events are covered. A pipe that fails in an instant qualifies. A pipe that's been seeping for weeks doesn't, regardless of how much damage it eventually causes. Your policy's personal property coverage pays up to your coverage limit once a covered cause is confirmed, minus your deductible.
Not all water damage qualifies. The event that caused the water matters more than the water itself. A slow drip behind a cabinet wall that's been leaking for months won't be covered. Neither will water that enters from a storm flood or backs up through a sewer line, unless you've added specific endorsements to your policy.
Most renters are surprised to learn that their landlord's insurance plays no role here. The building owner's policy covers the structure. Your belongings are your responsibility, which is exactly why renters insurance exists.
