The best way to return Tez to its peg is to use an additional pump. A pump is a device that helps to move liquid, gas, or air through a system. In the case of Tez, a pump can be used to move the currency back to its peg, or the predetermined exchange rate. The most common type of pump used for this purpose is a centrifugal pump, which uses centrifugal force to move the liquid or gas through the system. Another popular option is a positive displacement pump, which uses a positive displacement mechanism to move the liquid or gas. YouTube has a great tutorial video on how to use centrifugal pumps for Tez, which can be found at the link provided in the answer above. Additionally, there are many online resources that can provide further information on pumps and their uses.
