How To Install A Kitchen Faucet – All You Need To Know

Installing a new kitchen faucet or replacing an old faucet with a new one is a very easy job even if you have never done it before. It can be said that taking the old faucet apart is considered the most difficult task in the process of installation. After this stage is completed, the remaining jobs become absolutely easy for you because there is no need to use soldering or specialized tools.

One thing you should remember before beginning is that you have to check whether the new faucet matches with your sink. To do this, measure the distance from center to center as well as the number of holes.

Before You Shop

In case you want to replace an old faucet with a new one in your sink, the first thing you should do is to check how many holes it has by looking underneath the sink - usually from 1 to 4 holes. This will help you select the faucet that suits your sink.

Commonly, if your sink is the type of 3- or 4-hole sink, you can use a one-hole faucet and add a deck plate. However, the opposite thing is not true.

Remove the Old Faucet

To remove the old faucet, you need to turn off the valves of water under the sink first. Turn on the faucet to relieve pressure in the water lines. Make sure you stop water from running before disconnecting the lines.

The faucet includes two sets of nuts. The first set is usually made of metal and it fixes the supply line. Meanwhile, the second one is often made of plastic, especially in the new generations of faucets and is usually larger. Its function is to connect the sink to the faucet. In my opinion, to remove the nuts attached to the supply lines easily, it is advised to use a basin wrench.

First, you need to unscrew and then take out the bolts fixing the old faucet. In case the faucet comes with a separate sprayer attachment, you need to unscrew and take out the plastic nut.

The next step is to take apart the faucet body and sprayer from the sink and then clean the sink's surface.

Basically, to install a new faucet, you just need to do the reverse process of removing it (that you remove it by the hammer is not accounted of course). You need to use the mounting nuts to attach the new faucet to the sink. To be clearer, follow these steps below:


Firstly, you need to place the trim ring, plastic or rubber gasket over the faucet holes of the sink. Then, the job is to set the deck plate. To use plumber or caulk's putty when installing the gasket, you are advised to consult with the manufacturer's instructions.


The second step is to fill the hole(s) with faucet lines.


Next, install the nuts and washers underneath the sink. During the installation of trim or gasket ring, if you use plumber or caulk's putty, you should clean all excess under the sink.

In case you have pull-down faucets, you have to make sure that the quick-connect hose is attached to the supply pipe. After that, pull down on the hose and then, attach the weight.


The next step is connecting water supply lines together. If necessary, the plumber’s tape may be used. Make sure you don't screw the supply line connections so tightly. You should determine the cold and hot supply lines clearly so that other hoses are not affected. Then, link these lines with the supply lines and make it tightened.


After installing, you have to check whether there is any leak or not by opening all the cold and hot supply lines and the faucet. Then, clean all excess putty on the surface of escutcheons and provide the dispenser with a little soap. Make sure the pump has to be on the top.


Finally, make sure the sink's surface is clean. Remember to use the non-scratching scouring pad carefully to get rid of any caulking and putting left on the sink's surface.

Tips For Installing Your Faucet More Easily and Conveniently​

  • The first thing you need to care about is the structure of the holes. Before buying a faucet, you have to check the holes on the sink. In general, most sinks include 1 – 4 holes, which are designed with the space in different sizes to suit many types of faucets. If you find the faucet that fits your sink perfectly but it doesn't require all your sink's holes, don't worry because you can buy hole plugs available in most of major stores to shield all unused holes.
  • In my opinion, the Delta faucets is a really good option. With a smart design, most Delta faucets include the supply lines connecting directly from the inside of the faucet to closing valves. This helps reduce the number of flexible supply lines attached to the faucet. In addition, the installation of this faucet is easier than others. That connections are reduced also decreases the risk of leak.
