We’ll explore the common symptoms, helping you diagnose the issue accurately before proceeding with a replacement.
Common Symptoms of a Bad Flapper

Choosing the Right Replacement Flapper
This section focuses on selecting the appropriate replacement flapper for your specific garbage disposal model. We will discuss different types of flappers, their compatibility, and factors to consider when making your purchase. Understanding these aspects will ensure a smooth and successful repair.
Types of Garbage Disposal Flappers
Garbage disposal flappers come in various materials and designs. Common materials include rubber, silicone, and thermoplastic elastomers (TPE). The best choice depends on your disposal model and your budget. Some flappers have different sealing mechanisms or mounting configurations. Always cross-reference your disposal model number with the flapper specifications before purchasing.
- Rubber Flappers: These are the most common and usually the most affordable. They are generally durable but can wear down over time.
- Silicone Flappers: More resistant to heat and chemicals, offering slightly better longevity than rubber. However, they tend to be more expensive.
- TPE Flappers: A relatively new option, TPE flappers offer a balance of durability, flexibility and resistance to heat and chemicals.
Finding Your Garbage Disposal Model Number
The model number is crucial for finding the correct replacement part. It’s usually located on a sticker on the bottom of the unit or on the side. Write it down accurately before searching for a new flapper. A simple online search using the model number should provide a list of compatible replacement flappers.
