In the event that you do not have a grounded outlet to power the garbage disposal, you will need to install one. Adding a grounded outlet may cost as little as $5 when existing electrical wiring is placed a short distance away, plus an additional $75 for the electrician's labor. If a new grounded outlet needs to be added and electrical wiring does not yet exist, it will likely cost around $90, depending on labor and parts. If your project requires the addition of a new switch and wire, plan to spend an average of $5 to $10 on materials, plus about 30 minutes of labor at an average cost of $75 an hour.

Save yourself a lot of hassle and go with the same brand & model. By doing so you'll avoid having to remount and mess with the drain & sink connections. Save the old power cord so you don't have to buy a new one. You'll need to do some very minimal wiring work to pull the wires from the terminals in the old disposal and attach them to the disposal. Make sure to attach the green grounding wire to avoid getting shocked when you switch on the disposal!


My old built in guard got destroyed over the years. Rather than remove the whole disposal I ordered this, hoping it would solve the problem of the noise and the water and food particles that would fly out of the disposal onto my slightly hairy chest and face. This solved both problems. It is so quiet that it is like white noise. Such a calming sound that you can sleep to it.
Installing a garbage disposal involves tapping into your home’s plumbing and electrical systems, and both systems need to be handled correctly to safely install your garbage disposal. Someone with a lot of experience can handle the job in 2 or 3 hours—or maybe even less. Attempting a garbage disposal installation without any training will likely take at least double the time required for a professional to install the garbage disposal.
This part of the installation starts by removing the old mounting ring by loosening the mounting screws and then removing the snap ring, which holds the mounting assembly on the sink flange. You’ll need to use a flathead screwdriver to remove the snap ring. Next, remove the mounting ring by inserting the screwdriver into the tabs and turning the mounting ring assembly until it is free from the tabs. Be sure to support the bottom of the disposer as you do this. After this comes off, the entire mounting assembly will come free from the sink flange. Once free, pull the sink flange out from the top of the sink and scrape or wipe any old putty off the sink before wiping it clean with a towel.
• Run water before and after you use the disposal If something has been put in the disposal that should not have been, use tongs or pliers to pull the material out. Never use your hand. To clean a garbage disposal of built-up sludge and debris, fill it with ice cubes and a cup of rock salt and then run it for about five seconds. If your garbage disposal smells bad, you can deodorize it by running warm water down it while you grind a quartered lemon.
For any major issues with the garbage disposal, you should leave the job to a professional plumber only. Reaching your hand into the drain is dangerous, even if you believe the power is shut off. A plumber can help you evaluate the state of your disposal, and decide whether or not you need a new unit. Upgrading to a faster disposal unit with a higher horsepower can help to protect your pipes and make cleaning up after meals even easier.
