Step 5 · Prepare the New Drain Flange
Take a generous amount of plumber's putty and warm it in your hands by kneading it. Roll it into a uniform rope about 1/4 to 3/8 inch thick. Press this rope of putty firmly onto the underside of the lip of the new drain flange, forming a complete circle. For an extra layer of protection against leaks, wrap the male threads of the new flange with 2-3 layers of thread sealant tape in a clockwise direction (the same direction you will tighten it).
