When you get the faucet in position and retaining nuts firmly screwed, you can then get the water supply lines connected again. Open the supply lines slowly, give them a turn and when you hear water running, stop and wait until it stops. Doing this allows the water to slowly fill the lines. If you just flip them open, it can be like a shock to the system and may blow out a line or connection. With the water supply open, slowly turn on your faucet, just allowing a little water out, this also allows any air in the lines to escape gently.
