If you have a garbage disposal, you probably rely heavily on it to handle a ton of waste. They’re the best, aren’t they?

Garbage disposals are great because they keep your pipes clear and your garbage fresh by not housing stinky food scraps. If you don’t have one, you’re in luck because we’re going to show you how to install a garbage disposal in 9 easy steps.

First things first, you need to know which type of garbage disposal you plan to install. There are actually two primary types of garbage disposals: continuous feed and batch feed disposals. Both work great but can perform differently depending on how you use them.

You will also want to consider the size of the disposal you install. Some disposals are really big and may not fit under your sink. So when you go to the hardware store or start researching garbage disposals, make sure you have measured how much space you have under your sink—considering where your pipes are.

Your new installation will probably go much easier if you have an existing garbage disposal. This is because you’ll simply be disconnecting the old one and reconnecting a new one. But if not, you will need a few things to get started.

Now to the fun part; a step-by-step guide on how to install a garbage disposal. If you follow these steps, you’ll be chopping up food waste in no time!

This is probably the most crucial step. The owner’s manual for your disposal will have all the information you need to install it, including what tools and materials you’ll need, as well as specific instructions for your model. Reading it beforehand can ensure you don’t miss any steps along the way.

If you already have a garbage disposal in your sink, you’ll want to start by disconnecting it. But before that, turn off the power at your circuit breaker and turn off your water shut-off valve. Start by unplugging the power source then disconnecting the drain flange. Just hold it with one hand and turn it counterclockwise to remove it from the sink. Then, use pliers to unscrew the hose clamp from the discharge pipe.

This step may depend on whether your disposal comes with a power cord or not. Sometimes they do not, so it will need to be wired either with the old power cord from your existing disposal or a newly purchased one.

There is a small plate on the bottom that you can remove to reveal the capped wires to wire your disposal. Most cords and disposals will have the same standard colored wires. You should follow the manufacturer’s instructions for this, but in general, you’ll connect black to black, white to white, then the green wire connects to the ground screw.

You’ll want to remove the existing drain flange and replace it with a new one for your disposal. Pry it up gently, then remove any old plumber’s putty. Then, replace it with your new drain flange by first putting 1/4 inch of new putty around the underside and pressing snugly into the drain hole.

To keep it in place, put a towel or pad down and then a weight to hold it down. Or have a friend or family member apply pressure as you work underneath to mount the garbage disposal.

There are actually two types of attachments for garbage disposals. You’ll either have an EZ Mount or a 3-Bolt Mount. Both are simple enough to install, but the mounting ring would be different for each.

Now, you’ll want to carefully lift your disposal up to attach it to your sink mounting assembly. Secure it by turning it into place, connecting the snap ring, then tightening the appropriate fasteners.

Next, you must attach it to the P-trap, drain hose, or dishwasher hose. You may not have all of these, but it’s pretty straightforward, and you can see a walk-through in the video down below.

If you want your dishwasher to drain into the garbage disposal, you will need to carefully pop out the plugs on the side with a screwdriver and hammer. LEAVE THE PLUGS IN if you do not have a dishwasher hose to connect to.

Now you get to test it out! Keep a bucket underneath your garbage disposal if there is a leak somewhere when you run the water. Go ahead and run some water for a few seconds (up to a minute) and flip the switch to the disposal. If it looks good with no signs of leaks or weird sounds, go ahead and try busting up some food scraps.

If you are worried you might not be installing your garbage disposal correctly, it could be time to call in a professional plumber. When in doubt, it is best to hire a professional to ensure everything is connected properly and there are no leaks in your new system.
