How to Fix a Leaking Toilet Tank-to-Bowl Gasket · Step 5 of 7
In this video
After removing the old gasket from the flush valve, take the new yellow Tight Seal gasket. Stretch the gasket open with your hands and fit it over the threaded base of the flush valve. Ensure it is seated snugly and evenly against the bottom flange of the valve assembly to create a proper seal when the tank is reinstalled on the bowl.
Goal: Seat the new gasket on the flush valve
- The gasket is very stretchy and durable, so you can apply firm pressure to stretch it over the valve base without concern for tearing.

FAQs
What tools and materials are absolutely essential for this project, and are there any common household items I can use?
You'll definitely need an adjustable wrench to disconnect the water supply and tighten bolts, a bucket for draining, and a screwdriver. You likely already have a bucket and towels handy. Don't forget safety gloves and a new tank-to-bowl gasket system, which ideally includes new bolts and washers to ensure a secure, leak-free repair.
How difficult is this repair for a beginner, and what's the realistic time commitment?
This is a beginner-friendly project, mainly involving unbolting and re-bolting components. While the estimated time is 3 hours, it could take longer if bolts are seized or you encounter unexpected issues, like a stubborn tank. Taking your time, especially during reassembly and testing, is key to preventing further leaks.
Are all toilet tank-to-bowl gaskets the same, or do I need a specific type for my toilet?
Not all gaskets are universal, so it's important to get the correct type. While many are designed for common brands or have a universal fit, it's best to check your toilet's make and model if you're unsure. A universal gasket system that includes new bolts, like the Fluidmaster option, often provides good compatibility and a complete replacement.
What are the most common mistakes people make when replacing this gasket, and how can I avoid them?
A common mistake is overtightening the tank bolts, which can crack the porcelain bowl or tank. Tighten them evenly and snugly until the tank is stable, then test for leaks; avoid brute force. Also, ensure the gasket is seated perfectly flat and not twisted between the tank and bowl to create a proper watertight seal.
