We have had problems with this faucet since the beginning with the flow not being accurate. We thought it was a plumbing issue but we have no other issues with any of our other faucets, including the prep sink faucet.  Our buttons have been broken for quite some time now and it only sprays.  We now have to use needle nose pliers to pull out button tp stop the spray. After much frustration with the most important faucet in our home I decided to see if any others have reported same issues and I see they have. I will call Kohler today in hopes they will help get this fixed
