I purchased this faucet today as our old Moen was leaking.  It was more difficult to remove the old faucet than to install the new one; however, the new faucet doesn't work!  No water will come from the spout.  The box makes a sound when power is attached, but that's all. I've tried every possible solution from their website and tried calling them. I believe that the black box must be defective. (I have Moen fixtures throughout my house, but this is the first try with hands free solutions.)
