microbes and other stuff grows in it, tap water is pretty bad, try putting some into a container for a couple of weeks opened and you will see it has white stuff growing in it

bottled water is done in a very sterile way, so can last longer
Just pour yourself some tap water. You won’t die from drinking it but the fact that you've already drunk from the bottle two weeks ago isn't very hygienic and I bet it tastes purely of plastic.

I don't know why but the tap water at uni accommodation just doesn't taste right!

do they not have those water bottle thingys around instead of tap water?

the tap water is bad as all the old piping has the water sitting around in it, I cant drink plain tapwater either makes me gag
If it tastes off / looks off / smells off then it probably is.... if it looks tastes and smells ok...then it probably is...


If you become a human Mr whippy machine from drinking it... I can not be held responsible

How come the watercoolers (with bottles) dont stagnate ? :thinking:
Plastics are the worry.

Never leave water in the sunlight in plastics. Toxins are carcinogenic.

bottled water is a very controlled environment, sterilised bottles, and the water doesnt contact anything, and in a closed airless system so doesnt get many microbes and stuff in it, so it keeps for like a year unopened

you notice commercial watercoolers have the bottles upside down, to reduce the amount of exposure to air, just what is needed to let the water out
but then its open and they expect it to be used quickly

but fill your own bottle, even as clean as you can be, and it goes rank in less than 1 week, opened or closed.

if youve already drunk from it there will be bacteria from your gob on it......after 2 weeks those bacteria will have multiplied ten fold never mind the water.........it should be tret like every other thing exposed to air and bacteria and consumed within 2-3 days

apeears googling they say upto 2 weeks before bacteria and algae growth......depends on whats in ur gob i say

Ok, so when the water is being used, it comes out of the bottle and leaves a pocket of air - if thats left for a few weeks, why aint it green ?

, I think my bottle is 2 weeks and ok, i think its down also to the bottled water being much cleaner and not needing stuff like chlorine as tap water does
the air seems only part of it,

im sure people will say tap water is clean etc, but as far as im concerend If it stays cleaner longer, and tastes better, I think it is better
I used to fill a bottle everyday for carrying water about, but never tasted as good as buying bottled water, which kept for agen unopened and long enough opened

coz its air tight nothing can get in or out til the seal is broken.......

Some bottled water only carries its bottling date or a 'best by' date. These dates are helpful because the flavor of the water will change over time as it absorbs chemicals from its packaging. The flavor will not necessarily be bad, but it may be noticeable.

Leaching of chemicals from packaging is a health concern, but as far as toxic chemicals go, you can get exposure to most of those chemicals from freshly bottled water as well as bottled water that has been on the shelf a while. A 'plastic' taste is not necessarily an indicator that the water is bad; absence of an unpleasant flavor does not mean the water is free from contaminants.

While algae and bacteria will not grow in sealed bottled water, the situation changes once the seal has been broken. You should consume or discard water within 2 weeks after opening it.

its true, 2 weeks is pushing it, and really its a miracle it keeps that long, as pretty much nothing else does, nor does your own water from the tap

i think they only put the 1 year date on fairly recently to bottled water, like tinned food now has 18 months or so
they never used to!

Thats the bit I cant get my head around......
If the bottle is "AIR TIGHT" where does the air that replaces the water come from ? :thinking:

I dont think they expect containers that have been opened on water coolers to last weeks, its the unopened ones that last ages

at least its just air that is getting in, not peoples hand bacteria and mouth backwash

once they are opened no-one should expect 2 weeks for anything, it seems me and the OP are pushing our luck for the sake of science!

yes, i see monkeybum, but they at least started out sealed, once they are open and on the machine, it still is probably ok for only as much as 2 weeks
and i cant spit the water back into the container, so you are safe from my backwash!

what about the rumour that you shouldn't refill water bottles for the same reasons mentioned above i.e. toxins/carcinogens from the plastic? Cos i keep a few empty bottles at home and refill them for when i play football or go to the gym...
I've drank water that's been in a bottle for weeks before, lol/

We do that here sometimes but we wash them first before refilling - and we're still alive.
