Step 4 · Prepare and Position New Supply Line
Take your new Braided Stainless Steel Toilet Supply Line. Ensure the rubber cone washers are properly seated inside both coupling nuts. The larger nut (typically 7/8-inch ballcock) connects to the toilet fill valve, and the smaller nut (typically 3/8-inch compression) connects to the shut-off valve. Position the new line, making sure it isn't kinked or twisted, and that it reaches both connection points without being stretched.
