There are a variety of reasons why you might want to remove your garbage disposal. Perhaps it routinely leaks or simply stops working due to a lack of routine maintenance, and you need to replace it. You might also want to get rid of it entirely if your home uses a septic tank system that doesn’t play nice with garbage disposals.

Like even some of the most routine household maintenance tasks, removing a garbage disposal might seem beyond your skillset, but it’s actually a pretty simple thing to do. Regardless, you still need to follow specific procedures for your own safety and to prevent future problems from arising. Whether you’re replacing the garbage disposal or permanently removing it, here’s what you need to know.
Tools & Equipment
While you don’t need a lot of implements to remove the garbage disposal, certain items will make it much easier and safer. Some tools you will need include pliers, a screwdriver, a bucket, a wrench and a voltage detector. You’ll also need a garbage disposal wrench, which the disposal likely came with, though you can buy a new one if you’ve lost it.
Removing a Garbage Disposal, Step by Step
Follow these seven steps to remove your garbage disposal:
1. Unplug the Power
The very first step you need to take before you start any work with your garbage disposal — whether you plan to clean, unclog or remove it — is to disengage the power going to it. Go to your breaker box and find the circuit breaker for your garbage disposal, and turn it off. HGVT recommends that you test the wire with a voltage detector to be completely sure there isn’t any live electrical current.
2. Remove the Drain Pipe
Once you’ve cut the power, it’s time to unplug the drain pipe from the disposal. Place a bucket below the pipe to catch any water that might still be in it. You can use pliers or a wrench to loosen the fitting around it. Once you’ve removed the fitting, then just pull the pipe with your hand.
3. Remove the Dishwasher Drain Hose
If you don’t have a dishwasher connected to the disposal, you can skip this step. If you do, then you'll need to follow this additional step. There will be a dishwasher drain hose that’s connected to your disposal with a hose clamp. First, use a screwdriver to loosen up the screw of the hose clamp and simply disconnect the hose from it. You might also just need to use pliers to do it if it doesn’t have a screw-drive.
4. Hold the Disposal From the Bottom
If you have a partner with you, have them hold the bottom of the disposal before you fully disconnect it from the sink. If you’re doing this by yourself, place a box or something underneath it so that it can hold the disposal once you remove it from the sink. Since the disposal is quite heavy, it can damage whatever it falls on if you don’t take precautions.
5. Disconnect the Garbage Disposal From the Sink
After the drain pipe and dishwasher hose have been disconnected, it’s time to fully remove the garbage disposal. The garbage disposal will be connected to the sink with a mounting ring, which is located right under the sink’s drain hole.
Grab your disposal wrench tool and insert it into one of the loops on the mounting ring and turn it to the left until the disposal becomes loose enough to remove by hand. You might need to use some force to remove it. You can also hold on to the mounting bracket with your other hand for more leverage. Once the disposal has become loose enough, use your hand to turn it more and remove it.

6. Remove Wires From the Disposal
At this point, you still need to remove any wires that connect the disposal to your home’s power. Once again, double-check that there aren’t any live wires by using your handy voltage checker.
There will be wires hidden and covered by a plate on the bottom of the garbage disposal. Unscrew the electrical cover plate and unscrew any wire nuts inside that are holding wires together. Apart from these wires, there will still be another wire that goes into the disposal and is tightened by screws. Simply remove the screws and pull the wire out.
7. Remove the Mounting Ring From the Sink
Once those previous steps are done, you have the option to remove the mounting ring from the sink. If you plan on permanently removing the garbage disposal, you’ll need to follow this step. If you’re simply replacing it with a newer model, you might not need to remove the mounting ring since the newer model might simply fit into it.
Assuming you want to remove it, it’s relatively straightforward. Just remove the snap ring, and the mounting ring will come right off. Then use a screwdriver or wrench to remove the nut holding the sink flange. Use a scraper to remove any leftover plumbers putty around the sinkhole and add the new sink flange.
(From here, if you’re removing the disposal permanently but keeping the sink, you’ll of course need to reconnect the sink to drain pipes so that the water has someplace to go.)
