In our last post, we talked about how to connect the spray nozzle to the faucet.  Now comes the fun part - attaching the faucet to the supply lines underneath your sink.

As always, the standard disclaimer applies - your mileage may vary. Our house was built in 1952, our kitchen was updated in 1970(ish)… so we’ve got solid plastic supply lines. You, on the other hand, may have something a bit more pliable, which would lend to easier connecting.  Since we’re going to “refresh” our kitchen in the summer, we opted to leave the plastic supply lines for now until we install our dishwasher and reconfigure our sink and cabinet situation.  (You can bet that there will be quite a lengthy series of posts about our kitchen remodel.)

Meanwhile, the faucet! Let’s get that dude installed!

First, double check that your surface is clean. You’ll want to make sure that there isn’t any standing water, bacteria, mold, mildew, dirt or grime hanging around. While it won’t actually make its way into your water supply, you obviously don’t want to take any chances with encouraging contamination.

Next, take your faucet and set it in the three remaining holes in your sink.

Okay, this is the fun part - get under your sink and tighten the nuts to hold the faucet in place. Just like when we removed the old faucet, if you have a decent basin wrench, things could go a lot quicker.  Now run the supply lines to the bottom of the faucet handles and secure tightly.

You’re done.  Almost.

Turn the water to the supply lines back on slowly and test the faucet by turning on the cold water only and monitor for leaks underneath the sink.  Let the water flow for a good minute and use a flashlight - if you see any drips, turn off the water and check the connection between the cold water supply line and the bottom of the faucet handle. Wipe the drips away and run the test again.  If there are no more drips or leaks, repeat this process with the hot water.

Congratulations - you just installed a new faucet!
