1. Put the faucet threaded pipe thru the backsplash

2. Attach the nut washer combination but only thread it about 1/4 inch on both sides for now, so the faucet can still move.

3. While the faucet can move up and down freely put it in the up position

4. Attached the hard right angle fittings with 5 wraps of pipe teflon or liquid permanent

5. Now attach the faucet to the sink by tightening the nut washer combo from step 2
