Brand new kitchen faucets lost cold water over time
We remodeled our kitchen a year ago including all new copper piping and installing two new hansgrohe kitchen faucets. I've started to notice over the past few months that I was losing water pressure on the cold water side and now we've lost it all. Therefore only hot water coming out of the taps. It was somewhat of a gradual thing - losing the cold water. Any ideas on what could be wrong? How should we troubleshoot this?
