Another disappointment in faucets under $100. The supply lines that arrived with the unit were too rigid to hook up to existing ports and crimped. Replacing those lines was a special order, as even the local plumbing supply company doesn't supply those lines, which only have a nut on one end. The portion that feeds into the faucet base is a screw (male end) with two small rubber gaskets; if those gaskets aren't perfect, the faucet leaks, which ours did. I thought a $100 faucet would come with better hardware than the faulty $50 faucet it was replacing; I was wrong.
