We had these professionally installed less than a year ago. While they are nice to look at, we are now having to replace two of them due to lack of water flow and no hot water from either of them. Our plumber believes this to be a product defect. 2 out of 5 need replacement. I’d like to know if there is a warranty? Highly disappointed to have to purchase 2 new faucets plus pay a plumber AGAIN.
