Dress the Sink
"Dressing" the sink means to put all of the hardware on the sink before installation (Image 1)
Install the spout and handles (Image 2) Use a roll of plumber's putty around the seal to make sure it's water tight. Insert the valve bodies into the proper mounting holes, ensuring that the valve body marked "cold" is installed to the right of the center hole. Once the valve body is in place, slide the metal washer and nut onto the base, and then tighten it down.
Place the seal ring over the spout body, and then insert the spout into the sink. Place the metal washer and nut onto the spout shank and tighten the nut with a wrench.
Install the hot water valve the same way as the cold water valve. Don't forget to use plumber's putty.
