Id say to err on the side of caution and change, recycle the water in the garden or similar. 

I read with interest the use of water from storage tanks and containers, my Motor home has a 120 litre fresh water tank. I am new to motor homing and camping (recently retired) and keep the tank topped up and use aqua sol liquid or tablets according to the manufacturers instructions and would like to believe this will keep my water in best condition, I use the water for everything and drink it cold from the fridge. I live in West Wales and we have lovely soft water and I do like to keep it filled with local water as much as possible. I hope I am not putting too much faith in "Aqua Sol"and would be interested to hear other peoples views?
Having watched what Bear Grylls drinks I doubt a bit of stale tap water is going to do too much harm. I suppose if you have been brought up in a sterile environment not taking on a few iffy bacteria's along the way to build up resistance, then yes, there could be a problem?
When we were kids we would take provisions (jam butty and bottle of pop) and go off adventuring all day. When it came time to eat we would wolf down the food dirty hands an all, bit of dirts dint do us any harm. It’s a problem for youngsters now though as they are growing in too sterile conditions
and we drunk from a stream when we ran out didnt worry about the bug cow poo and whatever was in the water
well the do say would you drink the water knowing that fish have sex in it
