Why There Is Standing Water in Your Garbage Disposal: Causes and Solutions

Have you ever noticed standing water in your garbage disposal? It can be a concern for many homeowners, but understanding the underlying causes can help you address the issue effectively. In this article, we will delve into the reasons for the standing water in your garbage disposal and explore the best ways to resolve the problem.

Causes of Standing Water in Your Garbage Disposal

The primary reason for standing water in your garbage disposal is the backing up of the drain pipe. Your garbage disposal is typically situated at the lowest point in your sink line. This is why the dishwasher drain line is often routed up to a location that is above the sink bottom, as far as possible, before draining into the garbage disposal. If the drain pipe is not properly elevated, the water can back up and flow into the dishwasher, causing standing water.

Clearing the Drain

Step 1: Plunger Method

The best initial method to clear the drain is to use a plunger. Insert a stopper into the garbage disposal drain and plunge from the other side of the drain. You may need to hold the stopper in one sink and plunge the other at the same time. This method can help dislodge debris and clear the clog.

Step 2: Auger Method

If the plunger does not work, you might need to remove the P-trap to clean out the clog. Use slip-lock pliers to loosen and remove the P-trap nut. Then, swivel the curved section of the P-trap away and begin augering out the clog. It is highly recommended to call a professional plumber to do this. If you have inexpensive plastic pipes, attempting to auger them can result in failure of the pipes.

Step 3: Avoid Using Chemical Drain Cleaners

It is strongly advised not to use chemical drain cleaners such as Draino or Liquid Plumber in your garbage disposal. These substances can damage the disposal or cause other plumbing issues. If you have a double sink, consider using the other sink to pour in the line cleaner once the water level has dropped, ensuring proper drainage.

Addressing Clogged Kitchen Sink Drain

If standing water remains in the sink after you have cleared the garbage disposal, the drain is likely clogged. Disassemble the P-trap at the point where the curved section straightens out and heads into the wall. Loosen the nut with a pair of slip-lock pliers, remove it, and swivel the curved section away. This will allow you to access and clean the clogged area.

Tips to Prevent Standing Water in Your Garbage Disposal

To prevent standing water in your garbage disposal, follow these simple tips:

Regularly clean your garbage disposal to remove grease and grime that can clog the drain. Avoid putting large or non-degradable items down the disposal, such as bones, coffee grounds, and fibrous foods like celery. Consider installing a drain filter or screen to catch food particles before they reach the disposal.

By understanding the causes and following these solutions, you can effectively address standing water in your garbage disposal and maintain a smooth-flowing drain system.
