While most garbage disposals have a reset button, typical the disposal needs to be disassembled to remove debris. A licensed journeyman plumber can easily determine if the disposal needs serviced or replaced. Additionally, while repairing a garbage disposal we can inspect and/or address other undersink plumbing issues.
Generally garbage disposals have a ten year service life depending on use. Many new models have larger capacities, bigger motors, and run quieter. Also, newer disposals are more efficient at grinding material, making the use of your disposal safer for your plumbing system.
