This sink was installed one month ago. I am very happy with the size, style, and color of the sink. However, the flange on the disposer side sticks and recently came completely apart. I called Elkay and your customer service rep. sent me a new flange set. Before going any further, I want to make sure the drain on my sink is compatible with my garbage disposal. I have an Insinkerator Evolution PRO 880LT disposal. Is it compatible with this sink? If not, can you tell me what disposers are compatible? Thank you.
