Unscrew the copper pipes where they meet the faucet. The best tool for this task is a basin wrench, which has circular wrench-like jaws on the end of a long handle and enables reaching into tight places to loosen the nut holding the pipe. Use the tool in a ratcheting motion, rotating the nut a fraction at a time until it is loose enough to be removed with your fingers.
