Should you run the garbage disposal while the dishwasher is running?

So long as your dishwasher and your garbage disposal are properly installed, yes, you should be able to run the garbage disposal while the dishwasher is running as well. However, if your system is old, broken, or not properly installed, running both at the same time may cause an issue that shouldn't occur. Make sure to read your manual and be aware of what you put in your garbage disposal and when you can run it.
