So disappointed. I just spent $6,500 on a ridiculously expensive water-filtration system but I failed the inspection due to them having installed the unit in violation of the Uniform Plumbing Code. You would think a plumbing company would hire workers who know how to install the units they sell to be in compliance with the plumbing code but apparently not. It even took 5 calls to this company to have the inspection scheduled because their scheduler never gave me the courtesy of returning my calls.
EDIT on 10/20/15: the company called me back and will be issuing me a $1,500.00 refund due to the inconvenience and will be coming to my house today to address the code issue so this is a step in the right direction.
