You're working out in the yard, it's hot, and you're thirsty. You grab the hose for a cool drink. Is this wise? Better stop and think.

Some companies capitalize on this danger by offering health-conscious homeowners hoses that are made specifically for drinking water. But, they are also expensive and hard to find. And that's the On The House tip for today.
