Love the faucet, but it does not come with added 2.2gpm flow restrictor as advertised and stated in the installation manual to change from the 1.8gpm.  This is not a fluke, as we were sent the wrong finish (stainless) and had to return and reorder. Neither came with the black 2.2gpm flow restrictor.  After much research, the 2.2gpm was the main reason we ordered this Kraus KPF-1603 in Matte Black
