It is recommended to put the Angle valve on the plastic bag before operation so that we can prevent accidental damage to the faucet surface during installation. When connecting hot and cold water pipes, remember to connect the hot water pipe at the left and the cold water pipe at the right end. During the installation process, pay attention to the tightening force ought to be appropriate. The thread will be damaged easily if the force is too large, leading to loosening of the screw. But the force is too small, it may cause water leakage due to insufficient sealing. Therefore, don’t forget to check the sealing of the overflow hole and the filter basket when stainless steel sink installation is finished.
