- Buy a faucet that matches your sink. Your kitchen counter may have three or four holes or one large opening. If you're using a faucet with a sprayer, it will take either four openings or one large one and a separate opening for the sprayer. Make sure you get one that fits. Don't buy the cheapest faucet, or it may have plastic parts that will wear out quickly.
- Read the directions that come with the faucet. Every faucet is slightly different, and the booklet will include directions, tips and warnings specifically tailored to the hardware.
- Turn off the water and remove the old faucet, if there is one. You don't have to remove the drain lines, but if you want to it will give you more space to work with. If you do remove them, pay attention to every step you did to remove them, and make a diagram to help you remember.
- Put the new faucet fixture into the opening and seal the connection or connections with the counter. The faucet may come with plastic seals built in, or you may have to apply plumbers' putty around the connections to seal it. Read the directions that came with the fixture to be sure which way you need to seal the connections. Use the large nuts that came with the faucet to pull the faucet tight to the counter.
- Connect the water lines using braided flexible hoses. The hoses come into different lengths, but the connections on the ends are standard sizes. Use a wrench to tighten the ends to the water supply (hot and cold supply line).
- Put a bucket beneath the sink. Turn on the water for each water supply and flush it out to remove any particles so they won't get caught in your faucet. After flushing the lines, make sure the water is turned off, and connect the ends of the supply hose to the faucet. Tighten with a wrench but do not overtighten.
- Pull the sprayer hose though the counter opening. Apply thread joint compound to the central connection on the faucet and connect the sprayer hose to it. Tighten the nut with a wrench.
- Reconnect the drain lines if necessary, and test the faucet and sprayer. Look for any leaks.
