Can you replace an InSinkErator garbage disposal with Waste King? Yes, now you can. Waste King offers an EZ mount to 3-bolt mount adapter which can be used to mount any garbage disposal with an EZ mount on a 3-bolt assembly. So in effect, you can replace any InSinkErator garbage disposal with a Waste King.
Here is it;
The reason why this replacement is not possible is that InSinkErator disposals use a patented 3-bolt system while Waste King uses an EZ mount. These two are not compatible, here is a detailed post on it if you are interested.
So what this EZ to 3-bolt mount adapter does is; it basically creates an extension of the neck of the Waste King disposal and adds a 3-bolt mounting tab on its top.
To use this adapter kit you need some parts of the InSinkErator disposal; the sink flange, and the mounting tabs.
Here are the steps to replace an InSinkErator garbage disposal with a Waste King one
- Disconnect the InSinkErator disposal
You have to disconnect the old disposal first, but not entirely. Remove the water and electrical connections and twist off the disposal from the mounting ring. The 3-bolt assembly shouldn’t be removed. Then remove the mounting tab (the 3rd one) which is on the neck of the disposal unit.
- Insert the adapter kit through the above-removed mounting tab
Remember the mounting tab we removed from the InSinkErator’s neck? Slide the thinner part of the adapter kit through it. The top portion of the mounting tab should touch the top of the adapter kit.
- Install adapter kit to the Waste King unit
Just like installing the Waste King unit on the sink flange, connect the garbage disposal to the adapter kit. Tighten it. Now, this has become a garbage disposal with a 3-bolt mount compatible neck.
- Mount the whole unit on the 3-bolt mount
Connect the whole unit to the 3-bolt assembly like you would install an InSinkErator garbage disposal.
And that’s it!
