The first thing you need to do is turn your garbage disposal off and unplug the unit from the socket. Take some old towels or rags and use them to absorb all the water that has dripped from your garbage disposal. Then, place a bucket under the disposal unit so it can catch the leaking water. Finally, mop up all the areas the water has spilled over to if there are any. Opening the windows and spraying a good amount of air freshener to mask the foul odor wouldn’t hurt either.

You can now see the exact location where the leak comes from, making it easier for you to identify which course of action is best for you to take.

Before we explain what you can do when the bottom of garbage disposal leaks, you must first understand the cause of the problem. If the bottom of garbage disposal leaks, it is a clear indication that the seal on the protective shell case of the disposal unit has deteriorated. Either that or the interior shell itself has cracked. The purpose of the seal is to protect the garbage disposal’s motor and to protect the appliance’s electrical parts from moisture. If these parts of the garbage disposal get damaged, all the water coming from the sink can seep into the shell of the garbage disposal and that’s the reason why water is leaking from the base of your disposal unit.

Hence, instead of wasting your time trying to figure out how to fix garbage disposal leaking from the bottom, opt to buy a new disposal unit. If you have basic plumbing skills, you could even save money by installing the newly purchased garbage disposal yourself. In the end, replacing your disposal unit will cost you less money than repeatedly trying to fix a problem that will reoccur time and time again. You should be able to get about 8 to 15 years of use from a brand-new good quality garbage disposal so the pros can outweigh the cons in this situation.

What’s Specifically Cause the Bottom of Garbage Disposal Leaks

Bottom of garbage disposal leaks are more often than not, caused by the protective seal getting deteriorated over time. However, there may be situations where you have unknowingly sped up the protective seal’s deterioration. For example, using strong acidic or chemical solvents such as bleach or liquid sink drainers to clean your unit is never a good idea. Although those types of cleansers usually work wonders on regular sinks without causing much of a fuss, the harsh chemicals in these cleaning solvents can easily melt the plastic components of your garbage disposal unit. This is especially true with the frequent use of these acids. So you may want to avoid using typical drain and sink cleansers and consider using milder, more natural alternatives instead.

A mixture of baking soda and vinegar or lemon juice is a good and cost-effective alternative to your usual cleaning solvents. All you have to do is pour baking soda about a quarter cup into your drain and instantly add half a cup of either vinegar or lemon juice. The fizz that results from this homemade cleaning combination is exactly what you need to cleanse your drain. Afterward, you can rinse your sink with cold water, and voila, you’ve cleaned your sink without possibly damaging your garbage disposal.

Another way to prevent garbage disposal leaks is to avoid overloading your disposal unit with too much waste. As much as possible, you should try to keep the food load light by adding the waste little by little. When you fill your garbage disposal with too much waste, you end up overworking the motors and it produces excess pressure that can greatly damage the garbage disposal’s components. Overloading also increases the chances of clogging your garbage disposal which is a separate problem that you would have to deal with.


Garbage Disposal is Leaking From Reset Button

If your garbage disposal is leaking from reset button, it could be due to one of two reasons. One possibility is that the body of the disposal unit has been damaged and rust has spread, leading to cracks in the garbage disposal’s internal seal. The second reason could be because replacement for the flywheel gasket is needed as it has worn out. However, if you find that your garbage disposal is leaking from reset button, it’s best to buy a new unit instead. 

However, if only the flywheel gasket needs to be replaced then you’re in luck. This guide will walk you through how you can replace your garbage disposal’s flywheel gasket by yourself. All you need is a handful of tools, and basic plumbing skills!

off and unplugged

  1. The first thing you need to do is to ensure that the unit is in its OFF mode and that it is unplugged from the socket. This will help you prevent any accidents that may come your way when attempting to repair your disposal unit.

  2. Then, you have to disconnect the drain pipe from your garbage disposal to take it out from its place. Got a dishwasher connected, be sure to disconnect that from the unit as well.



  3. When pulling out the unit from under the sink, there are three main components that you need to look out for. First is the black hose, an orange or silver ring, and a tubular pipe that connects the disposal unit to the p-trap.

  4. Disconnect the black hose by loosening the screws with a hex nut screw. Afterward, the garbage disposal should get loosened up from the pipe.

  5. Next, using a hex wrench, loosen the ring that is at the top of the unit that connects the garbage disposal to the sink. Make sure that you are gripping the garbage disposal securely to avoid dropping it, damaging the unit further. Be careful when doing this because most of these units are heavy. You should now see the flywheel gasket after this.

  7. Finally, you can reinstall your disposal unit by following the previous steps in a reversed order.

Garbage Disposal Leaking From Side Pipe

The side pipe could also be another source of nasty leaks. When your garbage disposal leaking from side pipe, the most obvious solution is to check all the screws on the side pipes and tighten those that have loosened up over time. You could also opt to use a plumber’s putty to fix any loose seals if you’re only dealing with small drips. However, keep in mind this is only a temporary band-aid solution and that this won’t completely stop your garbage disposal from deteriorating. If the leak is coming from your garbage disposal’s discharge pipe, you may need to change the seal located between the holding nut and the discharge pipe.

If after many attempts of repairing the side pipe fails, then there’s no other way but to call a professional plumber to check and fix the problem for you. Spending a few extra dollars on hiring a professional service is always better than repeatedly attempting to fix a problem that is too complicated for you.
