A common problem from the users of garbage disposals is a leaking garbage disposal. If you are looking for answers to why is my garbage disposal leaking and how to fix a leaking garbage disposal, here I’m going to share the most usual reasons and easy fixes.
It certainly is an irritating issue yet usually not very serious. Unless the runny water causes molds, pest, and insects under your kitchen sink. Don’t worry, you can fix it by yourself. It creates a mess when there is a garbage disposal leaking water under your sink. You just need to know where to look for the leak and know how to fix it.
There is an easy way to find the location from where your garbage disposal is leaking.
Before you go to repair the disposal unit, you need to know what causes the usual leakages. If you know the place where your garbage disposal is leaking from, then read the below situations to know what can cause the leakage.
Common Areas to Look For:
In a very typical scenario, you will find the leak comes from any loose connection of different parts of the disposal unit. So, you should check the connected areas first. To find out the answer of why is my garbage disposal leaking, these are common areas you should look for.
1. Sink Flange:
Sink flange is the neck area of the garbage disposal. It is the part that attaches your disposal unit with the sink. If the installation is not done properly, you can discover water leaking from sink flange. On the other hand, after a long time of use, the sink flange can get loose and let water leak from that place.
Fix: In this case, you need to check few things.
In this case, you need to do a lot more work than just tightening the bolts. First of all, remove the disposal unit from the mounting. Then remove the mounting from the sink. Now re-install your disposal unit with some new fresh putty.
If the leak is small and you think there is no need to remove the entire disposal unit then simply put some fresh putty to seal the leaking area.
Beside a sink flange, a disposal gasket can also be the most usual cause for a garbage disposal leaking water. If your garbage disposal is leaking from the top, then do not forget to check the rubber gasket. Rubber gaskets seal the mounting to the flange. Over time a gasket gets old, and the rubber gets oversized. Sometimes it can develop leak or cracks, and it then is unable to maintain the tight seal with the mounting.
Fix: You need to replace the old gasket with a new one. Before going to buy a new gasket make sure you know the model of your disposal unit. Many disposal units have different size of gaskets though those belong to the same brand.

3. Dishwasher Connection:
A garbage disposal usually contains a dishwasher connection. It allows the dishwasher leftovers to get chopped and drained through the pipeline. A loose connection or a leak can occur in between the two hose pipes. If your dishwasher is connected to the disposal unit, then you must check if the leaking water is coming from the connecting pipe.
Fix: The garbage disposal port is connected to the discharge pipe of the dishwasher with a metal clamp. Tighten the metal clamp and check if the runny water stopped. If not, then you must check for a broken or cracked hose. In that scenario, you have to replace the whole hose line.
4. Loose Drain Lines:
A very common place to look for a leaky garbage disposal is the drain line connection. One connection is what I already mentioned a dishwasher connection. Another is a larger pipe that comes out from the lower part of the disposal and its connected to the sewer pipes.
This is the pipe that disposes the chopped-up food and water from your disposal unit to the drain line. If the hose connection is loose, then you can see water running out from the pipe connection.
Fix: These two pipes care connected with rubber gasket or screws. If it is connected with screws, try to tighten up the bolts. If it is related to a rubber gasket, check if the gasket got old and ruined. Replace the rubber gasket and check if still water runs or not.
5. Disposal Leaking from Bottom:
If your garbage disposal is leaking from bottom then it is not a good sign. Try to find out if there is any leakage from the upper outside part that is causing the water. If not then, most probably the disposal unit is old enough to cause a broken seal inside. Consider replacing the unit if you find out you have a disposal leaking from bottom, especially when it’s old.
Sometimes, it is seen that the disposal is leaking from the reset button. If the unit is relatively new, then you much check warranty and send the unit for a repair. If the unit is old, consider replacing it with a new one. You may consider repairing the reset button, but certainly, it will not run for a longer period.
So, these are the common solutions for how to fix a leaking garbage disposal. Hope you got the solution for your “Why is My Garbage Disposal Leaking?” problem. I’d suggest doing the fix by yourself, if you need to save the plumber’s cost. If your disposal is quite aged then consider buying a new unit rather investing and wasting money on it.Check Most Popular Garbage Disposals Here
