In this video
Place a towel on the floor under the toilet tank connection. Unscrew the water supply line connector from the bottom of the toilet tank's fill valve by turning it counter-clockwise. If the connection at the shut-off valve is old, you may need to use pliers to loosen and disconnect it as well, though the video only shows disconnecting the line from the tank.
Goal: Remove existing water line

FAQs
How long does replacing a toilet tank-to-bowl gasket typically take for a beginner, and what's the estimated cost?
For a beginner, this project generally takes 1 to 2 hours from start to finish, including draining and refilling the tank. The cost is primarily the price of a new tank-to-bowl gasket and bolt kit, such as the Fluidmaster Universal 2 in. Tank-to-Bowl Toilet Gasket System (2602G-008-T5), which is usually under $20. It's considered a beginner-level DIY plumbing repair.
Are all the listed tools absolutely necessary, or can I use substitutes for some?
An adjustable wrench and a 6-in-1 screwdriver are essential for disconnecting and tightening hardware. While a socket set, like the Husky 1/4 in. Drive Deep SAE Socket Set, can make removing tank bolts easier, an adjustable wrench can often suffice. A heavy-duty plastic bucket and plenty of absorbent towels (e.g., WYPALL L40 or HDX Select-A-Size Paper Towel Roll) are crucial for managing water and cleanup.
What safety precautions should I take, and what's the best way to prepare my bathroom before starting this project?
Always shut off the water supply to the toilet at the wall valve before starting and flush the toilet multiple times to drain the tank and bowl as much as possible. Place a heavy-duty bucket, like the Unger 6 Gal. Heavy-Duty Plastic Bucket, and plenty of absorbent rags or towels around the toilet to catch any residual water. Be careful when lifting the tank, as it can be heavy and awkward even when empty.
I replaced the gasket, but my toilet is still leaking. What could be the problem?
If your toilet still leaks after replacing the gasket, first check that the tank-to-bowl bolts are tightened securely, but do not overtighten, as this can crack the tank. Ensure the new gasket is properly seated and not pinched or off-center. Also, inspect the water supply line connection for leaks, and check the tank and bowl for any hairline cracks that may have gone unnoticed.
