Question 1

What is life expectancy of water?

Accepted Answer

I agree with Trapper, if you do nothing to enhance life span. However, there are options to stretch "safe consumption" window of H2O. I would strongly suggest a 'purification' process before using any long-time stored H2O, though, like boiling, carbon filtration, etc.

At The Ready Store, we often get this question. Many believe that you can use household bleach to purify water storage. Here is the best answer we can provide. Household bleach is not manufactured with human consumption in mind. The chemicals are much higher than what would be considered safe for human consumption. Having said that, if you don't have anything else, using bleach may be better than nothing.  It's not recommended to use straight bleach to purify your stored water if you have better options. It would be much better to purchase a water treatment that is guaranteed not to harm you when consuming. The water treatment we and many other companies carry would purify the stored water up to 5 years so you don't need to worry about changing it out or over contaminating the water with bleach.
