Product review (1 stars): Inconvenient and annoying
This product came with the new Insinkerator disposer for my new sink. Little did I know that I should have researched disposer covers in advance. The collar causes water to back up into the sink and to drain slowly. My plumber says this is just the way the product works. I wrote to Insinkerator, who got back to me saying it is designed to "pool" water at the top to reduce the noise from the motor. They call it "pooling." I call it water backing up into the sink. It makes prep work and cleanup inconvenient and annoying. Insinkerator has not yet responded to my question: Is there a replacement cover that allows water to flow directly into the drain? Meanwhile, I advise you not to purchase this product or any Insinkerator disposer equipped with it.
