Installing a New Faucet
Installing a new faucet is a simple project and a great way to upgrade the look of your kitchen or bathroom. You'll need to spend some time under the sink making connections and tightening nuts, so it's a good idea to clear out any items stored there so you can work easier. As you tighten nuts to secure the faucet, be sure to pop back up top for a quick look to make sure the faucet body is nice and square to the edge of the sink.
Apply Plumber's Putty at Base of Faucet
Apply a 1/4-inch bead of plumber's putty (or silicone caulk, if your sink is made of cultured marble) around the base of the faucet. Insert the faucet tailpieces into the sink openings. Position the faucet so that the base is parallel to the back of the sink, then press the faucet down to make sure the putty forms a good seal.
Screw on Washers and Mounting Nuts
From underneath the sink, screw the metal-friction washers and the mounting nuts onto the tailpieces, then tighten them with a basin wrench or slip joint pliers. Wipe away any excess putty around the base of the faucet.
Connect Supply Lines to Faucet Tailpiece
Connect the supply lines to the faucet tailpieces. Tighten the coupling nuts with a basin wrench or with a pair of slip-joint pliers.
Attach the Supply Lines
Attach the supply lines to the shutoff valves. Hand-tighten the nuts, then give them an extra quarter-turn with an adjustable wrench. To prevent damage to the tubes, it's a good idea to hold the valve with another wrench while you tighten them. Turn water on.
Flush the system
Flush the system. Install the cartridge and turn the water back on. While you're checking for leaks, flush the system until the water runs clear.
