A worn-out toilet flapper can lead to various symptoms. Here’s how to identify if the flapper has worn out based on the symptoms you mentioned:

1. **Tank Lever Dangles and Has Little Resistance**: This could indicate that the chain attached to the flapper is too loose or that the flapper is not sealing properly, allowing water to leak. It's often a sign that the flapper is not making a proper seal.

2. **Difficult Evacuation of Waste**: If the flapper is worn, it might not open fully or may not stay open long enough to allow the full flush, making it hard for the toilet to evacuate waste effectively.

3. **Tank Won't Fill with Water**: This symptom is not typically indicative of a flapper issue. Instead, it might be related to the fill valve or another part of the toilet’s plumbing.

4. **Water Seeping from the Tank into the Bowl**: This is a classic sign of a worn-out flapper. If water is continuously seeping from the tank into the bowl, it means the flapper is not sealing well, leading to constant water loss. If the fill valve cycles on and off, it may be trying to refill due to the loss of water.

Overall, if you notice water leaking from the tank to the bowl or if you have to flush multiple times, it's highly likely that the flapper has worn out and needs replacement. To confirm, you can inspect it for signs of wear, such as warping, discoloration, or cracks. Replacing the flapper is usually a quick and inexpensive fix.
