This is for a prep sink not a full size sink. High end faucet quick clean technology, installed for a day immediately realized it’s a prep faucet and uninstalled. Faucet hose too short and faucet too low for regular sink. Loved the function and water pressure. No parts missing. Water lines included. Installation instructions online at hansgrohe-USA.com.
