How long can water last in a water jug on the water cooler? It is from the tap-city water not delivered?

Question

I just bought a water cooler but opted not to have water delivered. The water jug I am using has a removable lid. I pour filtered water in the top from the tap. Then, I place the lid back on. The jug does not have a seal. Will this water go bad? I refill it about every two days. The water in the tubes in the cooler is probably okay but what about the water that sits in the jug? Thanks

Answer 1

It should be fine.  I've run water systems and we have swimming pool sized cisterns.  You may want add 1 tsp bleach per gallon of water to sit overnight to avoid getting algae about once a month.  Rinse it before using again of course.  It takes very little bleach to sanitize the water.  If your water is chlorinated I wouldn't worry about it at all.
