All the chemicals they now put into these plastic items........from years ago.
If you go to some of these $2 shops, you can smell the toxic plastics as you enter.
Now everything is being made more cheaper, and we just have no idea? what is in it.
Gone are the days, when it was safe.
Intersting question. I would worry about spiders, but that's easily enough avoided. I hadn't thought about the plastic, not to mention the fact that the hose doesn't get cleaned inside except by cold water so there could be mould in there.
I think it would be fine to do ocassionally as long as the water had been running long enough for any bugs to be flushed out. Of course this would only be if your tap water is good enough for drinking.
It would depend on where I was, and how thirsty I was. In my own backyard I wouldn't have a problem as it is Sydney water which is currently safe enough to drink and it would only be if I was in the bottom garden and had been working hard. I'd run the water first to make sure the water is running clean, but the little amount of dirt on rare occasions is probably better than the effects of dehydration. If it was a garden hose in another country where it might be grey water (or worse), then no, I wouldn't drink it unless desperate and there was no other source.
