Removing the knockout plug allows the dishwasher to drain properly into the garbage disposal.
Similar to children, sometimes household appliances require a little guidance to work together seamlessly. If you’ve recently installed a new dishwasher with an existing garbage disposal or vice versa, it’s important to ensure that you haven’t overlooked a small but crucial detail that could cause your dishwasher to fail to drain. In most cases, the culprit is a component known as a knockout plug. Fortunately, the solution is as simple as knocking out a plastic plug to allow water to flow freely through the garbage disposal drainage pipe.
Getting Started
To begin, unplug your garbage disposal to ensure your safety while working. You will require a hammer and a screwdriver for this task, and needle-nose pliers may come in handy for the final step. Look for a drainage port near the top of the unit where the dishwasher’s drainage tube is attached. If it’s already connected, use the appropriate screwdriver to disconnect it. The knockout plug is located inside the garbage disposal, behind the tube mount.
Locating the Knockout Plug
Insert the screwdriver into the drainage hole on the disposal unit. Does it go in smoothly? If so, the knockout plug has already been removed, and any drainage issues you’re experiencing are caused by something else. If the screwdriver hits a solid object, the knockout plug is present, and it’s time to remove it.
Removing the Knockout Plug
Use the hammer to lightly tap the back of the screwdriver against the knockout plug repeatedly. Move the screwdriver around the perimeter of the plug, tapping it with the hammer, to remove the entire knockout plug cleanly. The plug will fall back into the disposal unit. Use your hand or needle-nose pliers to retrieve it through the sink opening.
The Final Touches
If the plug is a complete circle, then you’ve done a great job. Check the inside of the now-open hole in the disposal unit for smoothness and ensure that the opening is as wide as the tube feeding into it. If there are any jagged edges, use a small file or paring knife to smooth them out. However, this is usually not necessary since knockout plugs are designed to be knocked out. Once the knockout plug is removed, attach the dishwasher drainage tube securely. Your dishwasher and garbage disposal are now ready to work together smoothly.
FAQ
1. What is a knockout plug in a garbage disposal and why do I need to remove it?
A knockout plug is a small piece of plastic or metal that is installed in the garbage disposal unit during manufacturing. Its purpose is to block the dishwasher drain connection. When you install a garbage disposal, you need to remove the knockout plug to connect the dishwasher drain hose. Removing the knockout plug allows the dishwasher to drain into the garbage disposal unit.
2. How do I locate the knockout plug in my garbage disposal?
The knockout plug is usually located on the side or bottom of the garbage disposal unit. To locate it, first, make sure the garbage disposal is turned off and unplugged. Then, use a flashlight to inspect the unit. Look for a small circular or rectangular shape that is different from the rest of the unit. This is where the knockout plug is installed.
3. What is the process to remove the knockout plug from a garbage disposal?
To remove the knockout plug, you will need a screwdriver or a hammer and a punch. First, make sure the garbage disposal is turned off and unplugged. Next, insert the screwdriver or punch into the knockout plug and tap it gently with the hammer. This should loosen the plug. Once it is loose, you can use your fingers or pliers to pull it out completely. Be careful not to damage the surrounding area or the garbage disposal unit while removing the knockout plug.
