I had this faucet installed In my new home kitchen built around 2 1/2 years ago. The faucet now starts dripping even when line it up to shut if off. I need to now close both the hot and cold water valves at the bottom of the sink to avoid the dripping that is very annoying. Really a big disappointment that such a costly faucet is broken within few years. Poor quality of parts for the price paid.
