Avoid These Common Mistakes When Using a Garbage Disposal
Using the disposal for everything
Garbage disposals are not meant to handle all types of waste. Avoid putting fats, oils, grease, coffee grounds, eggshells, and fibrous vegetables like celery and corn husks down the drain. These materials can clog the disposal and damage its blades.
Overloading the disposal
Putting too much food waste into the disposal at once can overload it and cause it to jam. Feed the disposal small amounts of food waste at a time, and wait for it to grind completely before adding more.
Not running enough water
When using the garbage disposal, be sure to run plenty of cold water. This helps to flush the food waste down the drain and prevents it from clogging. Run the water for at least 10-15 seconds after the disposal has finished grinding.
Not using the disposal regularly
Regular use of the garbage disposal helps to keep it clean and free of clogs. If you don’t use the disposal often, it’s a good idea to run it with a mixture of ice and water once a week to help sharpen the blades and keep it in good working order.
Putting metal objects down the disposal
Never put metal objects, such as silverware, pots, or pans, down the garbage disposal. These objects can damage the disposal’s blades and cause it to jam.
Using harsh chemicals
Avoid using harsh chemicals, such as bleach or drain cleaners, in the garbage disposal. These chemicals can damage the disposal’s components and cause it to malfunction.
Ignoring unusual noises
If you hear unusual noises coming from the garbage disposal, such as grinding or banging, turn it off immediately and call a plumber. Ignoring these noises can lead to serious damage to the disposal.
Not resetting the disposal
If the garbage disposal jams, it’s important to reset it before trying to use it again. To reset the disposal, unplug it from the power outlet and wait for at least 30 seconds. Then, plug it back in and press the reset button on the bottom of the unit.
