Changing your kitchen faucet is easy to do. If you’re replacing the faucet in your existing
sink, look underneath to see how many holes it has before you get the new faucet. It can
have from 1 to 4. A three-hole faucet won’t work in a single hole sink, but you can use
a single hole faucet in a three or four hole sink. You can just add a deck plate, and sprayer
or soap dispenser. If you’re also putting in a new sink, you
can buy the sink and faucet to work together. Plus, installing the faucet before placing
the new sink makes things a bit easier. Make a list of the things you’ll need for
the job. Things like supply lines, tools, plumbers putty, PVC primer, and cement. And
if the supply valves are in bad shape – or not there at all – get those, too. To begin the installation in an existing sink,
turn off the water valves underneath. Then turn on the faucet to relieve pressure. Turn
off the power to the garbage disposal and disconnect it. Always place a bucket underneath the valves
to catch water before removing all the supply lines. Have someone hold the faucet and from under
the sink, use a basin wrench to loosen the nuts. Then take off the nuts. At this point you can take the faucet off
the sink and clean away any grime or sealant. Keep in mind, different faucets install differently.
So be sure to read the instructions. Typically, here’s what you do. First, assemble the faucet. Then place the
trim ring, or deck plate if you have three holes like we do, into the sink. Feed the lines into the holes and position
the faucet. Underneath, install the nuts and mounting
bracket. For pull-down faucets, attach the weight and
quick connect hose to the supply pipe. You’ll need clearance underneath for the hose to
hang down. Next, hook up the water supply lines. Don’t
over tighten. Turn on the supply valves, check for leaks
and re-tighten if needed. Then remove the aerator and turn on the water slowly to flush
the lines and faucet of debris. Let it run for a little bit and check everything again.
Plug in the disposal and turn on the power. Replace the aerator… And with that, you’re done. Want more great ideas and how-to’s? Go to or just click to subscribe. Next, learn how to replace your kitchen sink.
