DIY Home Repair: Replacing a Garbage Disposal
If you’ve ever wondered if you need to call a plumber to replace a broken garbage disposal, the answer is no. This is a simple home repair you can do yourself. After our 10-year-old disposal went kaput, we researched online how to replace it and realized it was a quick and easy job. We picked up the same model we had before, the Badger, for about $100 at Home Depot.
According to the employee we talked to at Home Depot, if you are replacing your disposal with the same kind you currently have, the job is even easier because you don’t need to worry about the sink flange, which I’ve heard can be tricky to replace.
Since we’re dealing with a hard-wired appliance, we turned off the power before we got started. The Badger came with detailed instructions — this post is just an overview — so make sure you refer to the instructions before you begin.
In general, all you need to do is detach the disposal from the mounting hardware, drainage tube and the dishwasher (if you have one). Then, detach the wiring.
Next, unscrew the electrical plate on the new disposal, re-attach the wiring, align the disposal onto the mounting hardware under your sink, and screw on your drainage tube and dishwasher connection.
Turn the power back on, run some water and test out your new disposal. Easy enough and done in under 45 minutes.
