This is the 2nd house we installed a Kraus sink and faucet to replaced existing stuff. really only issue and very annoying to the wife is there is misdirected spray while rinsing items. I'm thinking possibly due to the spray head not being at  90 degrees to the sink base. I've taken the spray head apart to check for any build up and none. This faucet and sink are only about 6 months old, hate to already be replacing the faucet.
