The package and filling method matter
Factory-sealed and home-filled water do not share the same handling history. Preserve commercial seals and labels. For home-filled supplies, start with safe tap water and properly cleaned, sanitized food-grade containers.
Never use a container that held toxic chemicals or assume a disposable milk or juice jug is suitable for long storage.
Storage conditions protect the supply
Keep water cool and away from direct sunlight, gasoline, pesticides, cleaners, and flood-prone floors. Label each container with the fill date.
Rotate home-filled water every six months in line with CDC guidance and inspect the whole supply on the same schedule.
Inspect before using
Check for broken seals, cracks, leaks, unusual odor, discoloration, contamination, or contact with floodwater. Do not taste suspicious water to decide whether it is safe.
During a boil-water or do-not-use notice, follow exact local instructions; ordinary filters do not remove every hazard.
Frequently asked questions
Does bottled water expire?
Follow the bottler's date and storage directions. Packaging and storage conditions affect quality.
How often should I replace home-filled water?
CDC guidance recommends replacing water that was not commercially bottled every six months.
Can water be stored in a hot garage?
A cool, stable location away from sunlight and chemicals is preferable. Heat can degrade containers and water quality.
