How to:

Step 1: Pick a new faucet

  1. Keep the rest of your kitchen in mind when making your selection. Make sure the new faucet matches your kitchen.
  2. Ensure that you get a faucet that matches the number of holes in your sink. You determine this by taking a look underneath your sink.
  3. If your old faucet had a separate sprayer and you plan on getting a sink without a separate sprayer, you will need to purchase a sprayer hole cover.

Step 2: Prepare

  1. Clear everything out from underneath the sink
  2. One of the toughest parts of this job is the location and the space you are given. You may want to put an old towel down for cushion as you will most likely need to be on your back underneath the sink.
  3. Turn off your hot and cold water underneath your sink.
  4. Turn the faucet on and let as much water drain out as you can.
  5. Take a few pictures just in case you forget where something attaches.

Step 3: Remove old faucet

  1. Use an adjustable wrench to remove the nuts that connect the water supply lines to the supply valves.
  2. If you are having trouble loosening the nuts, apply some penetrating oil in between the nut and threads.
  3. Let the penetrating oil sit for around 5 minutes.
  4. The nuts should come off much easier now.
  5. Have a bucket ready underneath to catch any leftover water in the lines that may come out.
  6. If you have a sprayer, now would be the time to disconnect the hose that attaches to faucet.
  7. Remove the mounting nuts underneath the faucet that hold the faucet in place.
  8. Lift the old faucet out of your sink.

Step 4: Install new faucet

  1. Clean the area where your old faucet attached to your sink to remove any corrosion, hard water, or old putty refinements.
  2. Insert your new gasket onto the sink.
  3. Wrap the threads on the faucet with teflon tape.
  4. Attach supply tubes to the new faucet that you just put teflon tape on.
  5. Insert the new faucet into the holes.
  6. Put the new faucet into position and have a friend hold it there

While your friend is still holding the faucet, attach the mounting nuts underneath the sink. Be sure to not over tighter the nuts.

  1. Wrap teflon around the threads and attach the new supply lines to the supply valves.
  2. Connect sprayer if you have one.

Step 5: Test

  1. Remove your aerator if you have one and turn on the handles.
  2. Turn on water supply
  3. Let your water run for a few minutes
  4. While your water is running, check for leaks underneath the sink and and where the faucet attaches to the sink.
  5. Turn water off and put aerator back on.
