One of the things I was really looking forward to when we moved into our new fixer upper was being able to install a garbage disposal. You see, at our old house, we were on the septic system and so we weren’t able to have a garbage disposal. It’s one of those things you don’t really appreciate until it’s gone!
Logan is always on the hunt for good finds at our local Restore for Habitat for Humanity. He found this barely used Badger garbage disposal for a fraction of the full price cost (He thinks he paid about $15!). Even if you need to buy a brand new garbage disposal this Badger garbage disposal only costs $109 brand new and has great reviews.
The installation process for the new garbage disposal was relatively simple. I’m so glad Logughan has the knowledge of these everyday home ownership DIYs after working years in the property management/maintenance field. Most of all, I’m so grateful that we’re able to pass this knowledge onto you so you can save money on your home by doing it yourself too!
This isn’t the typical pretty home decor post you normally see from me…but Making Manzanita is all about making your house a home you love. And….a lot of times that comes with the simple efficiencies that we can add to our homes…like garbage disposals. One of my goals for you guys is to empower and teach you these simple DIYs (the home ownership tools of the trade) so you can save money! That means instead of paying a plumber, there’s more money in your pocket for fun renovations and fun things like cute throw pillows 😉 ….because we all need more throw pillows, right?
UPDATE: There’s a step by step video of this installation process at the bottom of the post 🙂
Be sure to follow your manufacturer’s specific instructions for installation and safety. Check to see if you need a permit for this installation. Be sure to observe any building and electrical codes. Lastly, be sure to contact a licensed electrician if you have doubts or questions about the electrical connections in your home.
Supplies for Badger garbage disposal installation:
- Badger 5 Garbage Disposal
- Dishwasher Connection (if you’re going to be connecting to your dishwasher)
- Plumber’s Putty
- Flanged Tailpiece
Step 1. Clean sink.
Before you get started installing garbage disposal, be sure to clean the area under the sink and clear out the sink of any debris. Place a towel under the sink to catch any water that may fall down when you’re installing the new garbage disposal.
Step 2. Unplug old garbage disposal (if necessary).
If you are replacing an old garbage disposal, unplug the disposal before beginning. We did not have a garbage disposal to begin with.
If you don’t see a plug under your kitchen sink, be sure to turn off the electricity to the disposal on your power circuit box.
Step 3. Disconnect tailpiece.
First, disconnect the tailpiece connected to the sink drain (or your old garbage disposal if you are just changing garbage disposal). The tailpiece is the plumbing pipe going horizontal between the two sides of the kitchen sink.
If you are changing garbage disposal that is connected to your dishwasher, you will also need to disconnect that.
Step 4. Unscrew your sink drain and remove.
Once everything is disconnected, you can simply unscrew your old sink drain and remove.
Again, if you are replacing an old garbage disposal, you will turn the old mounting ring counter clockwise to remove the garbage disposal.
Step 5. Remove old plumber’s putty from sink.
Once the sink drain (also known as flange) has been removed, you’ll probably notice old plumber’s putty. Thoroughly scrub out any plumber’s putty that may be remaining, You can gently scrap off plumber’s putty with a putty knife or use 0000 extra fine wire wool to remove stubborn putty.
Step 6. Install new drain in sink.
Take the new drain/flange off of the new garbage disposal. Roll out plumber’s putty into a 3/4″ rope and surround underside of drain where threads meet the rim. This will seal the drain to your sink.
Next, set your drain into the center of your sink drain hole. If you’re a perfectionist, make sure you pay attention to how the labels are facing on your drain. That would drive me crazy if those weren’t straight on. Firmly press down until you see putty start popping out around every edge of the new drain. Don’t worry about wiping off excess putty right now.
Step 7. Install mounting pieces to bottom of drain.
To give your new drain a little weight to stay in place while you work below the sink, you can place your garbage disposal on top of the drain that you just pressed into place.
Finish assembling your garbage disposal drain underneath the sink. You should have a flange, mounting ring and snap ring. Be sure you screw in the screws evenly on the mounting ring to get an even seal. Tighten each screw a little bit at a time and do not favor one screw more than the others. Hold everything on the drain assembly in place while you put the snap ring on to the flange until you hear it click.
Step 8. Remove excess putty from sink.
You can now take the weight off of the drain and remove any excess putty and clean the area.
Step 9. Install garbage disposal.
Step 10. Attach tailpiece.
Step 11. Install plug (or dishwasher connection hose).
Step 12. Secure all fittings.
Step 13. Plug in and test Badger garbage disposal.
