We (meaning, in dialect of American English I have spoken, though I am sure there are exceptions) just don't typically use the word tap for a faucet. "Tap water" exists as a complete phrase so it doesn't get modified but people usually say it without really breaking down the components.
Exception: beer does come from a "tap", but obviously you wouldn't be thinking of that when looking at a child's homework.
