reinvent the wheel

Do something again, from the beginning, especially in a needless or inefficient effort, as in School committees need not reinvent the wheel every time they try to improve the curriculum. This expression alludes to the invention of a simple but very important device that requires no improvement. [Second half of 1900s]
