A step by step guide on how to install a single hole faucet.

Preparing for the Installation

Installing a faucet can be a simple process, but you want to make sure you are comfortable and prepared for the installation. For example, depending on how you are going to install your faucet, put down a mat or a cushion so that you can be comfortable. You also want to make sure that you have all of the necessary materials for the installation process. If the faucet you ordered comes with any installation pieces, make sure they are all accounted for.

Have all of your water supply lines ready as well as your faucet. You are most likely going to need some type of wrench, preferably an adjustable wrench due to its versatility. Other things you may need are a flashlight, a bucket or towel to catch any water, screwdrivers, pipe cutter, and plumbing tape. You should always have these items handy. Another thing you want to make sure of before you install the faucet is to ensure that the area around the faucet is clean so that no issues come up when you place your new faucet on your sink or vanity.

Turn Off Water/Electricity

While your current faucet is still in your sink, one thing that you absolutely want to make sure you do is to turn off your water supply. This is something that some people overlook sometimes, so make sure this is the first thing you do. You may need to turn off the water in your entire house if you do not have stop valves underneath your sink for your faucet.

After the water is turned off, remove any excess water still in the supply line to the faucet and relieve any pressure. If you have any outlets near your faucet/sink you may want to securely cover up the outlet or turn the electricity off all together to ensure that no accidents happen. Remember to this step and double check it. If your water is on while you remove your faucet, an unnecessary mess will occur, adding a stressful problem to the process.

Remove the Faucet

Once all of the water/electricity is turned off, you are going to remove the faucet. This is where you want your bucket or towel handy because this is where some water will most likely leak out of the supply line. Remove the supply line from the faucet. The supply line is the tube connected directly to the faucet from underneath the sink. You can use your adjustable wrench to this. Turn the nut counterclockwise while stabilizing the water pipe. Since there are no hot or cold handles for a single hole faucet, there will most likely be one supply line.

After that, you will want to remove the hardware that is keeping the faucet secured to the sink, whether it be screws or bolts or anything of the like. After all of that is taken care of, remove the faucet from the deck. You will probably find that the space that the faucet was occupying is now dirty from the lack of cleaning it had. Get some all purpose cleaner and a sponge with a scrubbing side to remove residue from where the faucet was. Again, it is stressed that you make sure your faucet area is very clean in order to make this process as easy as possible.

Install the Faucet

Many faucets can have different installation methods so make sure you carefully follow the instruction manual for the assembly of your specific faucet. Most faucets can be installed with the following method. For many single hole faucets, the mounting hardware is located underneath the sink and connects to a shank. For a single hole faucet, the hot and cold water supply lines are usually built into the faucet itself, along with a built-in diverter.

Once you have the faucet ready to install, connect the supply lines. When connecting the supply lines, you are going to want to use a sealant on the threads of your supply line to make sure you prevent any possible leaking. Once the supply lines are attached, the next step is to fix the faucet to the sink. Depending on the faucet, this process may vary. Most faucets will be fixed underneath the sink as previously mentioned. Make sure you have somebody to hold the faucet in a fixed and centered position.

Double Check

Once everything is set up, go back and make sure everything is done properly. Read the manual over again, or if you do not have a manual, go back and review each step one by one until everything is double checked. Make sure all of the lines are connected, all of the nuts are tight and the faucet is centered and aligned properly. This is important because you don’t want any loose nuts or connections when you turn the water on.

Turn on the Water

Once everything is double checked, turn on the water. Before you turn on the water, make sure the faucet handle is down. Once the water is on, lift the faucet handle. You will most likely experience some air being released from your faucet before you see water come out. This won’t last long, as after a few seconds, you should see a steady amount of water flowing from your faucet.
