How to Fix a Leaking Toilet Tank-to-Bowl Connection · Step 2 of 6
In this video
First, ensure the water shut-off valve next to the toilet is turned off completely. Place a towel on the floor and a small bucket directly below the valve to catch any water that drains from the line and toilet tank. Using an adjustable wrench, loosen the metal nut connecting the supply line to the shut-off valve. Once loose, you can unscrew it the rest of the way by hand. Next, reach up under the toilet tank and unscrew the plastic nut connecting the other end of the supply line to the toilet's fill valve. This can usually be done by hand. Once both ends are disconnected, remove the old supply line.
Goal: Remove the existing toilet supply line
- Have a small bucket ready to catch the water that will drain out of the hose and from the tank's fill valve.

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.
