Product review (5 stars): PERFECT For Keeping Silverware Out Of The Disposal While Still Allowing Trash Down The Drain
This STP-DS InSinkErator Silver Saver Sink Stopper fits perfectly with a 2016 InSinkErator Evolution Spacesaver 5/8-HP disposal from Lowes.

I have a mother-in-law from another country who doesn't speak hardly any English, and was jamming everything garbage-wise down both sides of the sink. The disposal side and the pipe side. Inevitably, every few days, the sink was backing up. So, I installed dual garbage disposals. One in each sink. Voila, problem solved. Next issue... the silverware was going down into the disposal, so, obviously the InSinkErator Silver Saver Sink Stopper keeps just that from happening, while still allowing the garbage to go down into the disposal. When it's in the up position, the peelings and the cherios and other small garbage, goes down into the disposal, but not the silverware. The Silver Saver also twists and fits down into the stopper to plug and fill the sink, and it seems to hold water just fine.

I paid full price for these and was not asked to review or compensated for my review. I am also not affiliated with InSinkErator in any way.
