To remove the copper finish kitchen faucet, you'll need to disconnect the water supply lines and disassemble it. You may need to remove the water spout if it's attached to the faucet. Some faucets have a valve or stopcock that you can remove. Then, turn on the faucet again and try again. Make sure there's no water coming out. It's likely the faucet is faulty. If this doesn't work, try a different solution.
