A clogged garbage disposal unit can leak when you try to operate it without removing the clogging. What clogs up garbage disposals? Normally this would be expandable food like rice and pasta. Even large animal bones can also result in clogging and possible leak. Although coffee grounds help eliminate odors, allowing it to accumulate in the drain of the disposer will result in clogging and potential leak.
After using the lowest cost disposers for over 20 years now, I find the newest models have not withstood regular use for more than 5 years. The older models had a blue housing where this next step-up model has a black housing which I am hoping for at least 5 years use. Our oldest (blue housing) disposers have lasted at least 5 years and some are now almost 20 years old.
