I get water from the faucet, and it goes into the sink. I have sinks in my kitchen, and also in the bathrooms. The firefighters around here would probably get water from the pond, since there are no fire hydrants here in the boonies.

The hot water in my house comes from: (get ready) the hot water heater [ta da!]

Most people around here have a basement, but our house is a walk-out, and I tend to call the bottom floor both the basement and the lower level.
