This faucet needs work. I'm sure it is designed to save water as it has little water pressure. I ran 1/2" Pex hot and cold to the sink cabinet but the fittings in the faucet are so small the flow is bad. I contacted Kohler twice. First for a higher flow aerator, which did nothing. The second time they sent me a new faucet. It performs the same. My water filter faucet next to it has much more pressure. :(
