Review: Be carefull of the color - The product is an origina Insinkerator product, but the color was to much of a yellow brushed bronze and didn't look right with our gold fixtures so we sent it back. We replaced it with the gold and it matches our gold accents. Looks great with a black sink. Heavy duty and easy to install once you get the disposal out!
Review: If you have a Farmhouse sink you need this and possibly more - If you are trying to install an Insinkerator disposal unit (or even another brand) and have a Farmhouse sink you’ll need this Deep Sink Flange. The standard flange is 1-1/2 inches deep and it does not leave enough room for the thickness of a farmhouse sink. Here is the rest of the story... I go to my daughter's house to install a new dishwasher and end up installing a new disposal unit as well. She has a farmhouse sink and the plumber (or the person impersonating a plumber) installed the disposal on a 1” thick farmhouse sink with the standard flange. He did not use the backup flange and just had the screws directly contacting her expensive sink so the whole disposal unit was putting pressure on three screws. It was leaking badly, stinking badly and damaged the cabinet. [see graphic with screw indents in the sink] If your sink is thicker than ¾ of an inch you need this Deep Sink Flange but if your sink is between ¾” and 1” insinkerator does not have the full solution. There are two screw lengths they provide with the standard flange that comes with the new disposal unit which are the H1 which is 1-1/2 inches and H2 which is 1-1/8 inches. Now if you install a 1” sink in the Deep Sink Flange which is 3-1/2 inches deep that means you have about 2-1/2 more inches of flange. Of course, there is the snap ring which does take up some depth but the problem is that Insinkerator does not have screws long enough for a 1” sink and definitely not a ¾ inch sink. My solution was to add a second [see graphic] backup flange (kind of a kludge) and if it does NOT hold, I will obtain some longer stainless-steel screws. They should be called Insinkerator H3 screws and would be a 5/16-18 [18 threads per inch] and 1-3/4 inches long and the end should be flat so as to have better pressure on the back flange. Last comment – yes at $50 this deep flange is a rip-off and if it came with the 1-3/4 screws it would still be a rip-off but at least you could install your disposal unit.
