One of the most common questions friends have been asking me is why does my garbage disposal leak from the bottom? I have installed garbage disposals 3 times since Thanksgiving alone. Two of our friends had their garbage disposal leaking.

This is such a common occurrence so we decided to help answer your questions of what causes garbage disposal leaks. The only way to root cause leaking garbage disposal is to disassemble your old leaking garbage disposal and forensically determine where the water is coming from, and determine why you have a garbage disposal leaking from the bottom. This unit is an Insinkerator Badger 100, which we replaced with another new Insinkerator Badger 100.

Sources of garbage disposal leaks
There are numerous places that could spring a leak from the garbage disposal. We've had people report their garbage disposal leaking from reset button, some people report their garbage disposal leaking from base, and some report their garbage disposal leaking from side cracks. Unfortunately, most people think there's a way to repair and start looking for a garbage disposal leaking from bottom fix.

Well usually he leaks are caused by rust inside the unit, so it's not worth it to by a couple of expensive parts, you're better off starting with a new garbage disposal installation, and start your 13 year warranty all over again. Sometimes the problem with the lower end bargain garbage disposal model, they tend to corrode after several years of use, and most homeowners don't know how to extend the life of their garbage disposal before it starts to leak.

So anytime someone tells you their garbage disposal leaks from bottom or sides, just tell them put a fork in it, because they need to install a new garbage disposal. The rusty and leaking garbage disposal you see in this video came out of our 85 year old friend's house, after she complained to me that the garbage disposal leaks water out the bottom by the wires.
