Disposers fasten to the sink drain fittings in a number of ways--some use threaded plastic nuts, others large hose clamps--but the mounting-ring assembly shown here is the most common. To remove the disposer, support it from below and rotate the large, 3-tab mounting ring at the top counterclockwise until the unit falls away. Remove the remainder of the drain assembly by loosening the three bolts and prying off the retaining ring. Push the drain out through the sink hole and clear away any old caulk or putty.
InSinkErator garbage disposals provide a convenient and environmentally-conscious alternative to sending leftovers to landfills. Capable wastewater treatment plants can even recycle food scraps into energy and fertilizer. Plus, using garbage disposals can significantly reduce the amount of trash sent to landfills and reduce greenhouse gas emissions.
While you were testing the red switch at the bottom of the unit, you may have noticed a small opening in the center. If the unit is clogged or humming, you can try to free up the unit by using the wrenchette (Hex-Torx key) that came with your unit or a 1/4 inch allen wrench. Simply place the wrench into the center hole and move it back and forth until the whatever is clogging your unit is dislodged. Once your unit is moving freely, turn it back on to test. If the unit still won't turn on, it may be necessary to take the unit apart.
Start by turning off and unplugging the garbage disposal. Next, you’ll need the wrench that came with your disposal. If you don’t have it, you can buy a replacement in a hardware store that sells your disposal brand. Find the hex-shaped opening at the bottom of the disposal unit. Turn the wrench clockwise to dislodge whatever’s blocking the flywheel. When the object dislodges, you’ll feel the flywheel start to turn easily. Reset the disposal and run cold water while quickly turning it on and off repeatedly.
While it certainly isn’t always necessary to replace your disposal just because you’re getting a new sink or updating your kitchen appliances, it may be a good time to do so, especially if your unit is over ten years old. Since you already have professionals on the site, it may be more cost efficient and convenient to go ahead and replace an older unit instead of waiting for it to fail at a future date.
This thing is exactly as everyone else has described. I, like many others, replaced an old ISE Badger with this unit, and it's heads and shoulders above in quality, function, quietness, etc. It grinds everything in seconds (as opposed to batting it around in the chamber for multiple cycles like the Badger). The original plumbing from the Badger lined right up and worked the first time. I'm very pleased with this item... although, there is one thing that I want to note; I read somewhere that if you use the EZ mount system that comes with it, you won't need plumber's putty - one can just use the gasket. This is true ONLY if using a flat lipped SS sink, and even then the rubber seal is optional as opposed to the putty (you can use only one, the putty or the seal with a SS sink, but not both). It's better said that you WILL need plumber's putty, and if you have a stainless steel sink, you have the option to use the thin rubber gasket (I'd use plumber's putty). Other than that minor detail (which made me take an unexpected run to our local hardware store), this unit is great. The one last thing I will say is around quietness. I've read some reviews that talk about how quiet or not quiet it is. I don't understand the desire to have an ultra-quiet garbage disposal. I mean, one needs to run water while the run the disposal, and a full-blast of the faucet going into a spinning basket creates a notable level of sound anyway, plus I want to be able to hear the load of the disposal so I can know when it's clear. This unit is by no means noisy, but I just don't see the desire to go ultra-quiet. Again, this big-boy Waste King is awesome.
Next, you’ll connect the wires that you disconnected from the old disposer, to the new disposer. If this isn’t a replacement project, and you’re adding a new disposer where you didn’t have one before, you’ll first need to call an electrician to run the proper wires and a wall switch to the unit. For our project, the electrical wires and switch were already in place.
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.
The metal sink flange that sits directly inside the sink drain is typically sealed around the top with plumber’s putty (a clay-like sealant) and then secured from under the sink with bolts. If the plumber’s putty deteriorates, or the bolts loosen, the flange can no longer form a watertight seal between the sink drain and the disposal—which could cause a leak at the top of the unit.
