I have no problems with tap water! Just to be on the safer side of things though, I use a Brita filter. If one isn't available though (or if I'm at a restaurant), I will drink it straight from the tap.

I've noticed that some people will drink tap, but will have their kids drink bottled or filtered water only. We actually make barley tea from boiled water to drink every day, so it's a moot point for us...

Do you drink tap water? What about your kids?
