    Nick Marine with Marine Plumbing Service shows how to remove the P-trap and the pop-up assembly.

    Nick Marine: Hello! I am Nick Marine with Marine Plumbing. Today we are going to talk about removing that old lavatory faucet and installing a new one. Right now we are going to remove the P-trap and the pop-up assembly.

    First thing we are going to do is we are going to put a plastic bowl underneath the pop-up drain to catch the water. We are going to remove two nuts, inch-and-a-half of plastic nuts that hold the P-trap in place. The next thing we are going to do is remove the pop-up, and you can do this simply by taking pair of channel locks and twisting it off.

    First thing we are going to do is turn off the hot and cold water. Turn the valve to the right, until it stops, fully closes. After both valves have been fully closed, we are going to remove the hot and cold supply hoses by using small mini-channel locks and turning them in counterclockwise position and removing them. We are then going to open up the hot and cold valves on top of the sink that go to the faucet to drain any remaining water that is in this spout hose.

    One thing you want to do is make sure you have a bowl ready to drain any remaining water that is in the spout hose. We are going to use our basin wrench to remove the two mounting nuts that hold the faucet in place. When you are using a basin wrench, one of the tricks is to get kind of on your back, with your head totally inside, so you can see what you are working on.

    You are going to use the basin wrench and you are turning counterclockwise to remove the hot and cold water supplies, and you are going to do the same thing on the mounting brackets to the faucet as well. Once we remove the mounting nuts on the faucet, then we can go ahead and lift it up and take out the faucet.

    First thing we are going to do is we are going to lower the faucet into the holes very gently, because you don't want to chip the marble, you also don't want to scratch the faucet. Then you are going to take your two mounting nuts and turn them in the clockwise position, until they are fully tightened. As you are tightening them, make sure you pop your head back out from underneath the sink and look at the faucet, make sure its square, and then get a one last tightening with the basin wrench. Now, if you tighten it in place with the basin wrench, you are now going to connect your hot and cold water supplies using a basin wrench.

    You connect the hose, hand tight with your fingers, and then you take a basin wrench and you turn them in a clockwise position until they are fully tight. Once they are tightened, then you are going to work your way down this spout hose and get a pair of mini-channel locks and tighten those nuts to the actual files at the wall, for both the hot and cold side.

    Moving on, we want to install the pop-up drain. The pop-up drain, you want to slide the pop-up drain into the hole from beneath. There will be a rubber, looks like a cork. You are going to push that up into the sink and before it touches the sink you take some white Teflon pipe dope and you put it around to give it a good seal, because your sink top may be porous and that will fill up and voids or gaps.

    Then you take your channel locks and tighten the nut, which pushes that rubber deeper into the sink and tightens it until you can't turn it anymore. You don't want to overturn or crank the nuts, because you could crack them. Now, you can see the speed connect is ready to connect. Just hand tight connections.

    First thing I am going to do is turn on the left water supply. Then I want to get the right shutoff valve and turn it fully to the left and pressurize that supply as well. And then we are going to go ahead, go to the top of the faucet and open up the hot and the cold, and purge out any debris or any kind of dirt that's in the system. We are going to fill up the sink about quarter of the way. We are lifting up the pop-up drain, holding some water to drain it, evacuate the water. Testing the drain, the pop-up, the faucet, all at once. Then we are going to pop our head back under the sink and check for leaks. If there is any leaks at that time, we can take our wrench and do our last minute tightening up and address those problems as they occur.

    There you have it. We have just replaced your old lavatory faucet with a new one. The new one should last a lifetime. I hope these tips have helped you with your project. Good luck!
