Do not drink copper vessel water all year long. Once you start drinking water stored in a copper vessel you can continue this practice for three months and then take a break for one month (stop drinking water stored in the copper vessel). After a one month break, you can continue drinking water again from a copper vessel for next three months. This gives our body time to remove any excess copper deposited in our body. The body has its own mechanism of eliminating the excess of anything.
