Regardless of your choice, making sure that you choose a reliable model with a great warranty is always the most important step in choosing the right garbage disposal system.

Steps How to Install a Garbage Disposal

Step 1 – Cut the Circuit Breaker to Your Kitchen and Prep Your Workspace

Before going any further on your garbage disposal project, first cut the circuit breaker in your kitchen. This will help you to keep you safe as it will stop the flow of electricity to the various appliances and lights you have installed in your kitchen.

You can find the circuit breaker in your home either in your basement (in a single-family home) or often in the kitchen in a smaller studio apartment in the city. Make sure you the cut connection and test turning the lights on and off to make sure the power is cut.

Afterwards, place a bucket under the P-trap in your sink and disconnect the drainpipes. Remove the sink strainer and any putty that was originally put in place.

Step 2 – Apply Plumber’s Putty

With the new drain, apply plumber’s putty around the flange. You’ll want to firm push it into place to make sure. If you’re looking for a great putty product, here are a few options for you that you can purchase online today:

Afterwards, place a towel in the sink and put the disposal on the flange. This will keep it from moving and causing problems.

Step 3. Install the Fiber Gasket, Backup Flange, and Mounting Ring Under the Sink

While underneath the sink, you’ll next need to stack the following items: the fiber gasket, backup flange, and mounting ring. Slide this stack under the flange and install the snap ring. You can install the snap ring by prying it open and “snapping” it into the correct position.

Afterwards, you’ll want to make sure that you tighten all screws evenly against the backup flange. You may have some extra putty laying around, so take this time to clean that up as well.

Step 4. Connect to the Dishwasher Drain

You’ll also want to make sure that you route your dishwasher to the garbage disposal. You can connect to a dishwasher by replacing the drain plug from the inlet on the disposal. After you do this, you’ll want to connect the electrical cord by matching to the correct wire colors.

Push the wires in and reattach the plate. Then you should be good to go here.

Step 5. Connect the Drain.

You’re almost to the end of this process! To connect the drain to the garbage disposal, insert the gasket into the discharge outlet. Afterwards, you’ll attach the discharge tube to the flange and bolts mentioned earlier.

Next, you’ll hang the garbage disposal properly by aligning the tabs with the mounting ring. You can use the wrench that was included with the kit or your own wrench to lock the tabs in place over the ridges.

After this, you’ll connect the dishwasher drain and ensure that the discharge pipe is aligned properly. Make sure to use a T-pipe prior to your P-trap.

Important Things to Keep in Mind

After you finish installing the garbage disposal, you’ll want to take care of the following tasks:

  • After you install the garbage disposal, you’ll want to test the connections by inserting a stopper in the sink drain. Then you’ll fill the sink with water and check for any leaks in your installation. Finally, plug the disposal into an outlet and flip on the power switch! Don’t forget that you need to flip the proper circuit breaker.
  • Make sure that you follow the instructions in your manufacturer’s guide. While the steps listed previously provide a broad overview for many different types of garbage disposal installations, only your manual will have the specific instructions that you need to follow. Not all garbage disposals are designed the same way, so it’s especially important to follow the manual.
  • If you don’t feel comfortable completing the installation on your own, then you may want to consider calling a professional. Make sure that you reach out to a qualified technician that has experience installing garbage disposals. As always, be careful around moving parts powered by electricity.
  • If you live in an apartment building, there may be restrictions around garbage disposals. Always check with your landlord and read your lease to confirm that you can install a garbage disposal in your kitchen.
