Step-by-Step Guide On Installing Kitchen Faucet

There are many different types of kitchen faucets in the market, but each has a different removal and mounting process. Therefore, it is best if you first read the manufacturer’s manual that comes with your kitchen faucet box. There isn’t much difference with the procedure but there will be slight changes in the use of tools and the method of fixing the faucet in place.

Anyhow, the steps below follow a generalized method of replacing an old faucet with a new one, so you can follow them without any worry.

Shut Water Off at Supply Valves

First, shut off the hot and cold water valves to the sink. If you do not have a direct water supply under your sink, you need to turn off the main water supply. If the valves are stuck or harder to rotate, you can use a plier. Once this is done, clear the area under the sink. Put a small bucket inside the sink and turn on the faucet to drain any extra water running in it.

Disconnect Water Supply Lines

Next, use an adjustable wrench to disconnect the water supply line between the faucet and the supply valves. Unfasten the nuts connecting the tube. When the tubes are disconnected, tilt them in a bucket to ensure no water is leaking from the lines.

Remove Faucet Connections

Before removing the faucet, you need to remove its connections. For this, you should use the wrench to unscrew the nuts that connect the faucet from under the sink to the hose (supply lines). If you have a single-handle faucet, it is secured on a mounting bracket and nut that can be unscrewed easily.

Remove the Old Faucet

After removing the connections, you need to know to unmount the old faucet from its hole in the sink’s deck by pulling it out. Use the cleaner and the cloth to remove any dirt or debris surrounding the hole.

Install New Faucet

Now, it is time to install the new faucet. Pick up the rubber gasket and slide it down the supply tubes. Then, carefully mount the faucet onto the hole in the sink’s deck. Under the sink, add the mounting bracket and tighten the nut to fix the faucet in place.

Anchor Hot and Cold Valves

The next step is simple. You have to hold the supply tubes of the new faucet and connect them with their respective valves carefully. After that, tighten the nuts using the adjustable wrench.

Flush The Faucet & Check for Leaks

Your faucet is finally installed! But before you start using it, you have to turn the water on, remove the aerator, and let the water flow at full pressure. At this stage, you can look for any loose connections or leaks and tighten them. After a minute or two, put the aerator back in place and enjoy using your new faucet.

Tips for Installing a Kitchen Faucet

Sometimes it is difficult to loosen the nuts or remove the mounting bracket because it might be fixed in too tight. A simple trick to prevent this issue is to use a lubricant (oil). This reduces friction between the nuts and they can be easily unscrewed. Another tip is to apply medium pressure when removing the faucet so that you can get it out of the caulk seal without breaking anything else.

Do You Need an Expert or Can You DIY it?

The simple answer is: You can DIY it. Since the steps for installing the faucet are very simple and you do not need any demanding or complex material for the procedure, you can do it yourself without the service of an expert.

However, if you are worried about the risks of loose connections or harming the hardware, you can hire an expert for the job as well.

What Are The Top Advantages Of A Kitchen Faucet With Sprayer?

Replacing your old faucet with a new one has many benefits. Number one is that the pressure and the flow of water become faster and better. Here’s a list of many other advantages of a kitchen faucet with a sprayer:

  • Easier to clean dishes because the flow of water is quicker.
  • You can adjust the sprayer and point it towards the specific area where you need the most water.
