I gave mine bottled water because I hate our tap water here. Our tap water taste bitter. So depending where you are, you can drink it. Some area have nice tap water taste. I drink that without any problem. Now, for garlic water, I drink it, too. They even have those garlic tea. Vinegar with water--that sounds more like sinigang recipe. LOL! So what is good for me is good for my pigeons. I prefer prevention than cure.
Some garden hoses have this warning that they should not be used for consumption. The reason is that they contain lead and lead can cause cancer. Higher brand without lead obviously is the one that is safe for drinking. Just read the labels. Obviously back in Asia you drink well water. We have no running water there for a long time. But because we live near the beach, it taste saltier.
