Install a kitchen faucet by turning off the water supply, removing any obstacles in the way, removing the old faucet, attaching the faucet to the sink and installing new supply lines. Replace the obstacles, and turn on the water supply valves. The process usually takes about an hour.
- Turn off the water supply
Turn both the hot and cold water supply valves under the sink to the off position. If the valves are missing or nonoperational, turn off the water supply to the entire home.
- Remove obstacles
If the garbage disposal or traps are in the way, take time to remove them. Having a clear path makes it much quicker and easier to install the sink.
- Remove the old faucet
Disconnect the supply lines from the valves. If there are no valves or the valves are bad, remove and replace them at this time, and restore water to the rest of the home.
- Attach the new faucet to the sink
Attach flexible faucet supply lines to the new faucet. Place a bead of plumber's caulk around the edge of the new faucet base. Thread the supply lines through the holes on the sink. Start the faucet nuts over the threaded portion of the faucet that extends through the holes. Tighten the nuts with a basin wrench.
- Connect the supply lines
Connect the supply lines to the valve. Tighten the lines using an adjustable wrench.
- Replace the obstacles
Reinstall any drain parts removed earlier, including the garbage disposal.
- Turn on the water
Turn on the water supply.
