Installed this about a week ago and am already having issues. I spent an hour on the phone today with the manufacturer trying to fix the cold water line, which was entirely blocked. The cause of the problem, after much diagnosing, was the water restricter. They had me remove it. So now it works, but I had to remove a part the faucet was designed to have. The second issue is the the cartridge near the base of the faucet makes an odd sound when water is running.
