Our faucet was delivered last week, but when my husband went to put it in, it looked like we were given the wrong parts. The connection type in the sprayer did not match the threaded connection on the faucet. So we ordered another then returned the first. We just got the second in and it has the same problem. Please tell me what I'm missing, they can't have packaged 2 faucets wrong so I must not be understanding something. Attached is one pic with the sprayer end, faucet connection and parts bag. The second is of the instructions. Ideas?
