In this video
First, turn off the water supply to the toilet and flush it to empty the tank. Use a sponge or towel to remove any remaining water. Disconnect the water supply line from the fill valve. Locate the two bolts underneath the tank that secure it to the bowl. Use a deep socket wrench (a 1/2 inch was used here) to unscrew the nuts from these bolts. Carefully lift the tank off the bowl and move it to a work area like a garage or workbench.
Goal: Detach the toilet tank from the bowl for repair
- Place a towel or bucket under the tank to catch any residual water when disconnecting the supply line and removing the tank.

FAQs
How long will this DIY project take for a beginner, and what's the approximate cost?
This is a beginner-friendly project that typically takes 1-2 hours to complete, depending on your comfort level with plumbing. The main expense is a new tank-to-bowl gasket and bolt set, which usually costs less than $20.
What are the essential tools and materials I'll need for this repair, beyond what's listed?
You'll primarily need an adjustable wrench, like the Crescent 12 in. Chrome Adjustable Wrench, a flat-head screwdriver, a bucket (e.g., Unger 6 Gal. Heavy-Duty Plastic Bucket), and plenty of absorbent rags or towels, such as THE CLEAN STORE Cleaning Terry Towels. Work gloves are also highly recommended for comfort and hygiene.
What are the most common mistakes beginners make when fixing a toilet tank-to-bowl leak?
A common mistake is overtightening the tank bolts, which can crack the porcelain tank or bowl; tighten them only until snug, then give an additional quarter turn. Another error is not properly seating the new gasket, leading to immediate leaks, so ensure it's flat and centered.
Are there any specific safety precautions I should take before starting this project?
Always shut off the water supply to the toilet completely using the shut-off valve behind or beneath the toilet before beginning any work. Ensure you have a bucket ready to catch residual water when disconnecting lines and draining the tank, and wear work gloves to protect your hands.
