But here are a few tips to understand this workhorse. Leaks coming from the garbage disposal can due to several possibilities but for the most part it's the seal that separates the main drive from the blades. While the seals can be replaced, it is usually cheaper to replace the unit when considering part costs and labor costs.
As I mentioned before, there is a lot of water going through the unit. Prolonged use will begin to rust the metal pieces in the garbage disposal. The flange that attaches the disposal to the sink itself may have come loose through years of use and vibration.
I have found everything from egg shells to dinnerware to bottle caps to glass and everything in between inside the blade area. When a piece of foreign objects get stuck between the blade disc and the wall of the garbage disposal, the motor will seize causing it to hum and trigger the on-board circuit breaker and stops power for reaching the motor. If this happens to you, unplug your disposal, clear out any debris in the unit. Using a hex tool provided with the garbage disposal, you insert the tool at the bottom of the unit and turn until the disposal motor moves freely. There is also a reset button under the disposal to restart the unit. If repairing or replacing a garbage disposal is out of your comfort zone, Max Handyman can help.
