To remove the old flapper, first unhook the chain from the flush lever arm. Then, locate the two small 'ears' or rings on the sides of the flapper. These ears are hooked over two vertical posts on the sides of the flush valve tube. Gently flex the ears and slip them off the posts. You can now lift the old flapper out of the tank.

Goal: Take the faulty flapper out of the toilet tank

FAQs

What are the essential tools and materials I'll need for this flapper replacement?

Beyond the correctly sized flapper (like a Korky 2-inch or TOTO 3-inch), you'll need cleaning supplies. An E-Cloth Microfiber cloth, A-MAZ The Gripper Scrub Pad, a sponge, and water are useful for thoroughly cleaning the flush valve seat. Always have a towel handy for drips or spills.

How difficult is replacing a toilet flapper, and how long does it typically take for a beginner?

This is a beginner-level DIY project, often taking only 15-30 minutes from start to finish. The most challenging part is usually ensuring a good seal and proper chain adjustment, but with clear instructions, it's quite straightforward and can save you a plumber's fee.

My toilet is still running after replacing the flapper. What should I check?

First, ensure the new flapper is sitting flush on the flush valve seat and isn't obstructed by the chain. Clean the flush valve seat thoroughly again, as mineral deposits or grime can prevent a proper seal. If the problem persists, the fill valve might also need adjustment or replacement.

How do I know if I need a 2-inch or 3-inch flapper, and does it matter for my toilet?

The flapper size depends on your toilet's flush valve opening. Most older toilets use a 2-inch flapper, while newer, high-efficiency models often use a 3-inch flapper. It's crucial to get the correct size; you can measure the old flapper or the flush valve opening, or check your toilet's make and model number.
