Leaky garbage disposals are certainly no fun to deal with. There are several reasons why garbage disposals can develop a leak. There could be an inadequate amount of putty or sealant at the joint where the garbage disposal connects to the drain pipe from the sink. A leak can also spring from that area simply because the bolts holding the two pieces together are not securely tightened.
The point where food and waste exit the garbage disposal and move into the main drainage system is another spot prone to developing leaks. These types of leaks are similar to those that occur between sink drain and garbage disposal and can be remedied in the same way.
In general, the key to dealing with a garbage disposal leak is to locate the source. This will most often be where two pipes come together or where the pipes join the unit. However, as your garbage disposal ages, it is more prone to developing cracks in the body of the unit itself. When this happens, leaks can develop anywhere there is a seam or break in the body of the garbage disposal itself. With this type of leak, the only thing to do is to replace the garbage disposal with a new one.
Leaks are not the only problems that can develop in a garbage disposal either. Sometimes you may notice that your garbage disposal is making an unusual amount of noise when it is turned on. This is often the result of something getting in there that should not have, so you should not continue to run your garbage disposal. Turn off all power to the unit and see if you can reach or see into the garbage disposal to determine what is causing the problem.
If your garbage disposal is not grinding well even though it seems to be rotating fine, you may not be running enough water into it when it is turned on. The water is necessary to facilitate the grinding process, so be sure to keep it going at all times. If that does not solve the problem, you may need to have a professional come out and take a look at your system to find out what is going on.
