To find the right flapper for your toilet, check the size and shape of your flush valve. Most toilets use either a 2-inch or 3-inch flapper, so measure the opening inside your tank. Also, look at the mounting style—some flappers attach with a ring, while others use hooks. If your toilet brand is listed on the packaging, that's a good sign it will fit. When shopping at Walmart, you can compare product details and compatibility notes to help you choose the right one.

• Turn off the water supply to your toilet.
• Flush to empty the tank.
• Remove the old flapper by detaching it from the overflow tube and chain.
• Attach the new crane flapper to the same spots, making sure the chain has a little slack.
• Turn the water back on and test the flush.

Installation is usually straightforward, but always follow the instructions included with your flapper for the best results.

If your toilet keeps running, the flapper might not be sealing properly. This can happen if the flapper is worn out, misaligned, or if the chain is too tight or too loose. Check for mineral buildup or debris around the valve seat. Replacing the flapper with a compatible model can often solve the issue. If problems persist, inspect the flush valve and other tank parts for wear or damage.

Some universal flappers come with adjustable settings that let you control how much water is used per flush. Look for models with dials or adjustable float mechanisms. By fine-tuning these, you can help reduce water waste and potentially lower your utility bills. Always follow the manufacturer's instructions to avoid affecting your toilet's performance.

• Turn off the water supply and flush to empty the tank.
• Gently wipe the flapper and valve seat with a soft cloth to remove buildup.
• Check for signs of wear, like cracks or stiffness.
• If the flapper is damaged, consider replacing it for optimal performance.

Regular cleaning can help prevent leaks and keep your toilet working smoothly. Avoid using harsh chemicals, as they may damage the rubber.
