How to Fix a Leaking Toilet Tank-to-Bowl Gasket · Step 5 of 6
In this video
Carefully place the tank back onto the toilet bowl, guiding the tank bolts through the corresponding holes in the bowl. From underneath, place the washers and hand-tighten the nuts onto the bolts. Use a wrench to tighten the nuts, alternating between the left and right side to apply even pressure. Be careful not to overtighten, as this can crack the porcelain. The tank should be stable and not wobble. Reconnect the water supply line to the fill valve and hand-tighten, then give it a final quarter-turn with a wrench.
Goal: Securely reattach the tank to the bowl and reconnect the water supply.
- Do not overtighten the tank bolts or the supply line nut. Overtightening can crack the porcelain or damage the fittings, causing leaks.

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.
