Turn Off The Power

The first step is to make sure that the power to the home has been turned off. This is vital when installing any kind of electronic device. If the disposal unit turns on before you are ready, it can often lead to some injuries, and damage to the unit. Make sure that the power stays turned off until the device has been completely installed. 

Remove The Existing Garbage Disposal

If you’re replacing an old unit, you’ll first need to remove the old one from the kitchen. If you’re putting in a new model, you’ll be able to skip this section. The way that you do this might vary slightly, depending on the option that you’ve chosen. If you’ve got a model that connects to the dishwasher, you’ll need to remove the hose that links them. You’ll be able to use a screwdriver to help you do this. If you don’t have a model that connects to the dishwasher, don’t worry about this part.

Next, you’ll need to remove the waste line. However, before you do this, make sure that you have an old towel and a bucket ready, in case there’s some water still caught in the pipe. When ready, loosen the nut and remove the pipe from the disposal unit. 

The final step is to undo the screws which are attaching the disposal to the sink. You should be able to do this using a screwdriver, loosening the connection around the mounting nut, at the top of the unit. Once the disposal is off, you can take off the other parts of the mount. After everything is off, you might want to rub any remaining food scraps from the hole with a damp cloth. Now, you’re ready to start installing the new unit. 

Wire The Disposal Unit

When you’re ready, you can get ready to start installing the new unit. In this case, you want to start by making sure that it’s been wired properly. How to do this will often depend on the model that you choose. For example, some models might have the wires coming out, ready to be plugged in. In other cases, you’ll need to unscrew the bottom of the unit and do it yourself. If this is the case, you should refer to the instructions in the owner’s manual. They’ll often contain detailed instructions on the correct way to wire everything up. 

Install The Drainage Flange

For many disposal units, they’ll require you to put in a drainage flange. To do this, you’ll need to form a long line of plumber’s putty, which you then attach in a circle under the bottom of the sink. This should allow you to slot the flange at the top of the sink. When doing this, make sure to apply even pressure around the flange, so it sticks into position properly. It’s often easier to get a friend to help you with this step. They’ll be able to apply the pressure above the sink, while you work beneath the sink to install the flange. 

Put In The Mounting Ring

To finish the installation of the flange, you’ll need to put in the mounting ring. This can be done below the sink. As you do this, you should alternate between each screw. This will ensure that everything gets tightened up evenly, so the flange sits securely in the sink. 

Mount The Disposal Unit

Now, you’ll be able to safely mount the disposal unit, you will be able to put it onto the mounting ring. As you do this, you’ll need to make sure that the disposal unit is facing towards the pipes.  Also, you might want to get an object that you can rest the disposal unit on. You should see a lower ring, turn this clockwise until the weight of the unit is supported by the mounting ring. Once done, use a screwdriver to lock it into place. 

Connect The Pipes

The next step is to connect the pipes. In some cases, you might need to measure the pipe and cut it to length. Then, you’ll need to screw it into place. As you do this, you’ll need to read the owner’s manual. This will allow you to make sure that everything has been done properly, so the unit works correctly. Depending on the model, you might also need to screw in the connection to the dishwasher. 

Turn On And Test The Disposal Unit

The final step is to turn on the disposal unit and make sure that it’s working properly. Make sure that the garbage is going through the unit properly. You should also check that there are no leaks. If there are, you’ll need to use a screwdriver to tighten up that connection. 

As the unit starts to age, these connections might loosen slightly. If you see this, grab a screwdriver and re-tighten them. After about ten years, it might be time to replace the unit entirely. At this time, you can simply repeat this procedure to attach the new unit. 

Conclusion

As we’ve seen, installing a garbage disposal doesn’t need to be a difficult process. In most cases, you won’t need any plumbing experience or specialized equipment. This makes installing a garbage disposal achievable for most kitchens. To find the perfect model for you, make sure to check out this useful garbage disposal guide.
