We are doing a new kitchen and would like one single lever pull-down faucet at the main sink. Currently in our old kitchen, we have a main faucet and an additional filtered water faucet. Is it possible to combine the two into one main faucet so you have one less faucet at the sink? Are there problems with pressure? Is this reasonable? I'm trying to have less clutter around the faucet area. But, I want maximum function also.
