Connect Supply Lines to Faucet

1.	Connect the supply lines to the faucet tailpieces.

2.	Tighten the coupling nuts with slip-joint pliers or a basin wrench.

Step Three

Apply Sealant & Position Faucet

1.	Apply a quarter-inch bead of plumber’s putty around the base of the faucet. If your sink is made of cultured marble, use silicone caulk.

2.	Insert the faucet tailpieces with supply lines into the holes in the sink.

3.	Position the faucet base parallel to the back of the sink and press the faucet down.

Step Four

Screw on Mounting Nuts

Attach the faucet's supply lines to the shut off valves and tighten the nuts. Give the nuts an extra quarter-turn with an adjustable wrench while holding the valve with another wrench.

Step Six

Apply Sealant to Sprayer Base

Step Seven

Screw in Mounting Nuts

1.	Place the friction washer over the tailpiece (if needed).

2.	If your sprayer hose is not attached to your sprayer, do it now.
