How To Install a Garbage Disposal

How to install a garbage disposal and connect the P-trap and drain.

Here I install a Moen EX75c disposal, which is more powerful and quieter than the average Insinkerator installed by most contractors on new sinks. This unit also comes with a preinstalled power cord so the only other thing needed is a 1.5" P-Trap kit found at Home Depot or Lowes.

P-Trap kits with only two washers and nuts usually only give you one slip washer. The other washer is a reducer. Normally, your sewer drain stub-out will have a washer and nut on it. Here mine didn't so I needed three nuts and two slip washers.

FYI: if installing a dishwasher drain line to the disposal you need to remove the disposal drain cap, seen here in blue. Some disposals have a black cap that you push into the disposal and then you pull it out from the top.

Here I'm using a switched outlet. If you don't have one, here is another option:

My daughter's garbage disposal stopped working months ago, and the replacement she purchased has been sitting in the garage. Although I have completed many DIY projects, I thought this one was out of my league. Not anymore! Thanks for making what I thought was impossible possible.

My old garbage disposal stared leaking and this video saved my Sunday. Quick trip to Home Depot for a new unit, installed it, and now good to go. Thank You

This was super helpful, especially since I didn't have a garbage disposal to start with, and almost all the other tutorials I have found assume you already have piping in place!

[DenialDan]

A lot of other tutorials have me second guessing if I need other things to install. This video made me realize I have everything I need and don't need to buy more pipe

Disposal just fell out of the bracket about an hour ago. It's 1:47am. Thank you for this.

[johnfolmar]

Great video, easy to understand and camerawork shows what is needed. Especially helpful was the tip about the snap ring tool.

Thank you ! Best tutorial I've seen on YouTube for garbage disposals.

[trollmunchies]

Thanks man! I’ve never replaced a garbage disposal before. You made it easy and as a result of saving money on labor I got a better model

[stevenj]

I have never thought to use an oscillating tool to cu that type of pipe. Great idea!

[wanderwoman]

Swapped out my disposal quickly and without a single snag - thanks to you!

[christianmanriquez]

Thank you. I started as helping someone drive and I got bored and started getting out the van and now the boss is paying me an extra $7 dollars per hour after 6 months. This a great trade and you learn from many; pros & cons.

[charlesharvey]

I just had to replace the disposal unit and used most of the existing parts. Lot easier than I expected. Thank you for your guidance.

[bigsidable]

This video was very helpful for when I changed out my garbage disposal recently. Thank you!

[yolandaarzate]

I just replaced my garbage disposal myself and saved $200.00.Thanks for the help!

[rigogarcia]

You are awesome. Very experienced and articulate. Thank you very much for this video and for the one on how to install the dish washer!

[mixmastermikebiz]

This is my exact setup in a basement kitchen that did not previously have a garbage disposal. I was curious how to handle the P-trap, this was very informative and helpful! I'm going to go for it now instead of hiring someone, will let you know how it goes :)

[brians]

Thank you for this straightforward, easy to follow video...

[amazingfire]

Thank you for this video. Your camera angles made it so much easier to understand. I was able to figure out what was wrong and how to fix it easily.
