Before You Begin
Many of today's faucets are designed for easy installation. Some use a rubber gasket to seal the joint between the base of the faucet and the sink, while others require a bead of plumber's putty around the base. If the faucet is going in a new vanity, plan to install it before the sink is put in place so it is easier to work on.

Unpack the faucet and check that it is the model you want, and read the installation instructions.
Turn off the water before you begin.
Step 1 : Install the gasket or apply the plumber's putty
Depending on the type of faucet, follow the directions to install the gasket or apply plumber's putty.
Step 2 : Position the faucet
Place the faucet on the sink or countertop. The faucet has flexible riser tubes already installed. Align them with the holes in the sink and lower the faucet body in place. Align the faucet body with the back of the sink or counter and align the center toggle with the center hole in the sink and push the valve body down to force the toggle through the hole.
Step 3 : Tighten down the bolts
From the underside of the sink tighten the hold-down bolts. Some models have large washers and nuts that screw on the valve tailpieces, other are held in place with brackets that bolt to the underside of the valve body. Use a standard screwdriver to tighten the set screw in the back of the faucet body. You may have to hold the toggle that is now underneath the sink to keep it from turning. When the toggle reaches the underside of the sink, firmly tighten the screw to lock the faucet in place. Thread the caps of the flexible supply lines onto the stop valves and tighten them with a wrench.
Step 4 : Install flexible riser tubes
If the faucet is not equipped with built-in riser tubes, thread them on to the valve tailpieces and then attach the risers to the hot and cold water supply.
Step 5 : Clear the aerator screen
Remove the aerator screen from the spout and run the water through the faucet to flush out any debris that may be in the pipes. When the water runs clear replace the aerator.
Step 6 : Turn on the water
Turn on the water at the main power supply.
