Product review (5 stars): An Elusive Find: Custom Flange Compatible with Waste King EZ Mount System
I moved in to a new home recently and found that the existing disposer was in need of replacement.  Instead of replacing just the disposer, I decided to go ahead and completely replace the entire sink, including the faucet, flanges, and disposer.  I decided to purchase most of these items on Amazon due to the excellent prices and free Prime shipping.  However, I was troubled by the lack of documentation and details regarding the compatibility of the different parts.  I'm writing this review along with a review of the disposer I purchased in an effort to fill in these gaps for future purchasers.

For the disposer, I went with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Waste-King-L-1001-Legend-Series-1-2-HP-Continuous-Feed-Operation-Waste-Disposer/dp/B000LNIK6C/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Waste King L-1001 Legend Series 1/2 HP Continuous Feed Operation Waste Disposer</a>; unfortunately, the flange that comes with the disposer has a highly reflective chrome finish which will not be suitable if you want to coordinate with faucet hardware that isn't also chrome.  Though there are many custom flanges to choose from, the Waste King will not be compatible with most of them since it utilizes the EZ Mount system for attaching the disposer to the sink.  This assembly is not compatible with the majority of the custom finish disposer flanges found on Amazon and in most other stores; most are intended for Insinkerator (ISE) disposers.

There is an adapter kit available (<a data-hook="product-link-linked" class="a-link-normal" href="/Waste-King-3101-ISE-Adapter-Kit/dp/B000HE6ECM/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Waste King 3101 ISE Adapter Kit</a>), but I would highly recommend only using this adapter if you are replacing an existing ISE disposer and want to use the hardware already attached to your sink; if you are starting from scratch you would still need to purchace the ISE mounting hardware in addition to the adapter.

I should also note that there are some Waste King branded flanges for sale, but the only ones I found that are compatible with the EZ Mount system have plastic finishes, like white, biscuit, etc.  Waste King flanges that offer a metal finish are only for Waste King disposers that use the very different 3-bolt mounting system, which are a bit more expensive than the EZ Mount variety.

If you plan to start from scratch with all new components as I did, using an EZ Mount disposer along with a suitable disposer flange like the Waste Maid will simplify your installation and help you avoid headaches and delays caused by ordering incompatible parts.  If you insist on a certain brand of disposer flange you will have to get the flange, ISE mounting hardware, and the adapter.  This should work, but at a much higher cost than the Waste Maid flange alone.

As far as the flange itself is concerned, I was impressed with the quality of its manufacture; it's quite heavy and solid, unlike some of the ISE flanges I've handled.  The machining of the threads is very smooth and I had no trouble screwing the disposer's mounting hardware onto the flange during installation.  So far the finish seems to be holding up well, but it should be expected that a disposer flange will take some abuse and may not look perfect forever; however, in this case there isn't much of a finish to worry about anyway, so I expect it will look nice for quite some time.

My only complaint is that the stopper had some minor nicks and dings, primarily on the "handle" portion; it looks as if it may have been dropped on a concrete floor.  Also, it does not seem to sit very tightly in the flange; it doesn't leak or anything, but it seems to fit so precisely that degradation in the rubber seal could cause a leak in the future.  These are very minor issues and aren't really noticeable, but they do make it seem like the stopper was used instead of new; that being said, I do not feel that they should reduce this product's rating.

In conclusion, I would not hesitate to buy this flange again.  If you're installing a new EZ Mount disposer and need a custom flange, this is the way to go.
