You are either running the unit improperly or the unit is malfunctioning.

When the garbage disposal unit is run inappropriately, it leaves behind the trash and food particles in the grinding chamber and drains. This consequently piles up the residue in the unit. The residue, constituting of food particles, starts to spoil and as a result, the foul odor begins to emanate from it. So if you are wondering why your garbage disposal stinks, one of the reasons can be your improper usage of the disposal unit.


2. Disposal Unit is Overdue for Cleaning

Lack of cleaning of the unit is an imperative reason why garbage disposal smells. If you want to keep your disposal unit from smelling like rotten eggs, you need to ensure that regular cleaning is executed for the system. The cleaner your garbage disposal unit is, the lesser possibility there is that you will have to encounter foul odor.

This will ensure that all the particles of the food are flushed out of the system and nothing is left behind that can become a source of odor in your drain pipe of the unit itself.


3. Bacteria Housing in Your Disposal Unit

The odor that accrues from the disposal unit is due to the bacteria that start growing on the remaining food particles that are left behind. As you sense that a stronger smell is coming out of your garbage disposal, rest assured that it is because bacteria have started feeding on the spoiled food particles that are in your disposal unit.

Garbage disposal has all the elements that are favorable for the growth of harmful agents like bacteria. It is moist, warm, and dark. With improper cleaning and lack of disinfecting measures, bacteria and fungus growth is promoted.

The dirt and debris coming their way engage the pipe completely and make it difficult for the waste to pass through. This blockage radiates foul smell from the pipe that emerges out from the sink and discharges into your kitchen.

 So at times, it is not your garbage disposal smelling but the drainage pipeline that is associated with it. This requires you to indulge in deep cleaning frequently so that any blocked pipe is identified timely and the trash is taken care of before it contaminates your home and causes a foul odor.

If you are wondering why your garbage disposal smells like rotten eggs and cannot grasp the reason because you have a freshly cleaned unit, then you need to look deeper. It could be a blocked pipe causing the trouble.
