Total oversight on my part- Kitchen cabinets are in and grante counters with sink are now installed. In installing the granite counter- they also installed a 9' deep "undermount" sink. When I went to eyeball the garbage disposal install I notice the outlet from the disposal is 2-3" lower than my drain. I cannot lower the drain at all since it comes in from the side wall and making it any lower would throw off the natural pitch out the main. I can buy another sink which is same dimensions but 7.5" deep but I don't think that helps me enough. Do they make any disposals where the outlet is less than 6" down???
I'm beside myself knowing I made this poor error and feel there is no way out.
HELP

You sure you won't be okay once a p-trap is installed??

I really can only change the sink with one that will fit in the opening. The counter is already cut to fit the sink

the P trap is what comes out of the disposal and goes down correct? Won't it still be an issue if the main drain is still higher than disposal outlet?

You can get a closer coupled disposal- perhaps a Badger. But it still looks a little close.
Also look at sinks with a shallow bowl on one side

Garbage disposers are not necessary---you could learn to live without it---

I did something similar when I remodeled a kitchen a few years back. I can tell you with certainty that the drain MUST be below the disposal's outlet. If you can't figure a way for that to happen, don't install the disposal.

2 suggestions:

Get a GD with a shorter neck. The 1 in your picture is not typical.

I do not see why you can not open the wall and lower the trap arm tee. PIA but doable.

thanks all- I cannot lower drain line- thats part of the issue- the drain comes in from the basement (split level house)- The kitchen is on a slab- The drain goes out the back (which is actually the basement ceiling)- then pitches all the way to the right (about 20') to the main drain outlet- It's as low as it can go

Insinkerator GD's have the drain hole 6"(measure to center of hole) below the bottom of the sink, yours looks a lot more that that .

Lower only the tee at the back of the cabinet. It should have no bearing on whats 20' away.

Thanks E..... I can't- I looked at that- The "T" is basically connected to a 45 then a 90 degree turn to the right where it begins it's slope to the main out. I guess I could drop the connection at the main line and slope it more but that could be a huge project.....
