How to uninstall a HIMARK bathroom sink faucet?
Turn off the faucet twisting in a clockwise direction. Use a wrench to undo the set screw on the pop-up drain bracket located at the base of the faucet. Remove the pop-up drain lever from the faucet and keep aside. Unscrew the remaining nuts underneath the faucet with the wrench. Remove completely from the top of the sink.
