I bought the replacement faucet from Costco and paid $250 for black mountain to install. The plumber broke a plastic piece used to stabilize the faucet from beneath the counter. He said he would have to charge me again to come out and make it right once I get the replacement piece. For $250 you would think it would be done right now matter how many times they have to come out. He said the piece shouldn’t have been made of plastic. I agree. Now I’m working with Costco and delta to get a new part. This is more of a headache for me than I bargained for!
