When your garbage disposal is working correctly, it shouldn’t take longer than a few seconds for it to grind up any food waste. However, if your disposal is taking longer to grind up garbage, it may need replacing. This can happen for a couple of different reasons.
The first reason can be the grind ring. It’s a common misconception that garbage disposals have blades. Garbage disposals actually grind up waste using a grind ring, which operates by centrifugal force pushing debris into the outer ring where it’s ground up. If the grind ring is dull or clogged with food, it will struggle to work. The ring can be replaced by a licensed plumber, but it’s usually more cost-effective to replace the unit.
The other reason for long grind times can be the motor. As motors age, they weaken, which will cause the garbage disposal to struggle with doing its job. If your motor has weakened to the point it requires a long time to grind any food waste, you should consider calling a dependable plumber to replace the unit.
