How to Install a Kitchen Faucet

Dull, worn out hardware can make your kitchen tasks seem like a drudge. A new faucet can improve the ambiance and make your chores more manageable and enjoyable.

Here’s how to install a new faucet:

Tools and Material:

  • Basic Wrench
  • Pliers
  • Adjustable wrench
  • Faucet Kit

And you’re off!

Turn the water source off from the valve under the sink. Next, open the tap and let the water drain out. Cut off the water supply to the hot and cold taps.

Take off the Old Faucet

  1. Detach the connecting nuts and mounts at the back of the faucet. Take out the tap, dismantle the sprayer hose and lift it out.
  2. After you clear the surface, scrub around the area to break up any deposits.
  3. Examine the sprayer hose for any defects. Change it as needed.

If your faucet comes with a sprayer, now is the time to attach it.

  • Slide it through the opening and send it up through the middle of the tap.
  • Connect it with a wrench to hold it in place.

Connect the Faucet

Check your manual to see how to assemble the new faucet. It’s a good idea to set up the connections before you set the new assembly in position. After the setup, run the connection lines through the opening in the sink.

Since the assembly lines are already hooked up, attach the pipelines to the valves.

Fasten the Flexible Connectors

Some faucets models are different, so the length of the hot and cold tubes may be uneven.

  • It’s best to attach flexible connectors to convert the faucet to your type of installation.
  • Next, affix the connectors to the fittings on the supply tubes on your faucet.
  • Fasten the connections in place with a wrench.

Helpful Hint

Ensure the faucet sits firmly in place. Twist and tighten each connector to minimize any damage to the supply lines.

Position the Faucet

Slide and push the supply lines into the middle of the faucet hole. Check to ensure the gasket lines are straight before setting the faucet in place. To further secure it, place a nut and washer to the end bolts and tighten them with a wrench to prevent the tap from shifting.

Reinforce the Connections

If you have not done so, now is the time to affix the other flexible connector to the shutoff valves.  An adjustable wrench will help tighten it up. Switch the water back on from the vale, then turn on the faucet to ensure the pipeline is flowing smoothly.

#2: How to Install  Kitchen Faucet with a Sprayer

A kitchen sprayer is a useful addition to the sink to make washing up more comfortable and enjoyable. A pull–out sprayer can come out and retract when required. You can install a new sprayer in a few easy steps with the right tools.

Toolkit and Materials:

  1. Basin Wrench
  2. Plumber’s Putty
  3. Sprayer
  4. Kitchen Faucet
  5. New Supply Lines
  6. Silicone Caulk
  7. Adjustable Wrench

Stop the Water Flow

Shut off the water from the valve or the house’s water source.

Make your Connections

Attach the lines to the tailpieces in the faucet.

Use a wrench or pliers to fasten the nuts.

Seal your Connections

Spread some plumber’s putty around the faucet base.

To prevent permanent staining:

use silicone caulk to seal around countertop edges made of marble or similar materials.

  • Align the tailpieces with the connections into the faucet holes in the sink.
  • Place the faucet base in line with the backsplash of the sink and push the faucet down.

Screw in the Nuts

Attach the friction washers and mounts to the tailpieces in the faucet. Use a basin wrench or pliers to tighten them in place. Clean away any plumber’s material from around the faucet with a cloth.

Attach the Lines to the Valves

Join the supply lines to the shutoff valves and secure the nuts in place.

Hold the valve with a wrench, and use an adjustable wrench to give the nuts a few turns to fuse them together.

Seal the Sprayer Base

Put some plumber’s caulk around the sprayer base to seal it off. If your edges are of marble, use silicone caulk to avoid damage.

Slide the tailpiece of the sprayer into the opening hole of the sink.

Install the Mounting Nuts

  1. Position the friction washer above the faucet’s tailpiece.
  2. If the sprayer hose is not already in place, attach it to the sprayer.
  3. Connect the mounting nut to the tailpiece.
  4. Strengthen the connection with a wrench or pliers.
  5. Use a cloth to clean any putty around the faucet base.

Attach the Sprayer Hose

Twist the sprayer hose onto the hose nipple at the faucet base and fasten it with your hand. Reinforce it with a wrench or pliers to hold it firmly in position. Turn the water back on and check for any leaks.

#3: How to Install a Single Hand Faucet with Sprayer

If you are thinking of changing your existing faucet, why not install a single hand faucet with a sprayer?

The upgrade will enhance the functionality and convenience of your kitchen tasks.

Materials and Tools:

  • Single Handle Faucet (with pull-out sprayer)
  • Side Sprayer
  • Pipe supply lines
  • Plumber’s tape
  • Lubricating Oil
  • Torchlight
  • Screwdriver
  • Wrench
  • Safety Glasses
  • Towels
  • Sink Cleaner
  • Pipe Cutter
  • Bucket

Prepare to Work

Before you begin, prepare yourself and the area. You will be lying on your back, so place a pad or pillow to protect your back while you work.

  • Have a torchlight handy to spot hard to reach areas.
  • Place a bucket and some rags or towels under the sink to catch water that may spill out.
  • Protect your eyes from flying debris with a pair of safety glasses.
  • Clear the sink area of any cleaning supplies or storage items.
  • Switch off any electrical power lines under your sink.

Turn off the Water

Turn the valves under the sink to the right to close off the water supply.

If you have any problems, you may need to shut it off from the house’s water source.

Once the water is turned off, release the faucet handles and let any remaining water drain out.

Disconnect the Pipelines

Take out the old faucet by disconnecting the water supply lines under the sink.

The hot and cold valve have separate supply lines, so you’ll need to disconnect each one.

  1. Take off each nut with a wrench, turning it to the right.
  2. Keep the pipeline steady as you unscrew the nut, to prevent damaging the connecting lines.
  3. When you complete one line, turn to the other and repeat the process.

If the valve continues to leak, turn off the primary water source and change the valve.

Take out the Faucet Parts

They include:

  • The pipe supply line
  • The valve
  • The mounting nut

Before you take out the supply line, remove the connections.

Helpful Hints:

The hot and cold connections are part of the faucet handle. You’ll need to pull the mounting pieces over the supply lines.

If diverters are attached to the spout and sprayer, separate the connections before you take off the parts.

Removing the Faucet

Chances are, your plumbing is in a tight slot, so you’ll need the right tools and grip to take off the fittings.

You will need: A basin wrench has a set of angled teeth and can swivel to allow the tool to help you reach difficult areas.

There are some brands of the plumbing installers that help you master several under sink tasks simultaneously.

Disconnect the diverter from the sprayer hose

  • Detach the nuts that join the water lines to the hot and cold taps.
  • Remove the bolt and separate the diverter from the hose.

Once the water lines are disconnected, you can safely remove the mounts.

If any parts show wear and tear, clean them up with some oil before you re-attach them.

Take out the old faucet

The faucet is attached to mounts that connect to a stem which houses the hot and cold lines. Your single hand faucet integrates both hot and cold water lines.

  1. Take out the mount and pull the faucet free. If there is leftover caulk, give it a few tugs to dislodge.
  2. When the faucet is out, clean around the area with the appropriate cleaner for your type of hardware.

How to choose the best faucet

Choose a faucet depending on the number of holes in your countertop. Some sinks have as many as four holes.

  • Measure the distance between each hole to get the length between the number of holes in your countertop. Most sinks generally carry an 8-inch spread.
  • Your single handle faucet already has the handle attached to the spout and is otherwise known as a center set faucet.
  • A pull-out sprayer is ideal if you don’t have enough holes for a separate installation in the countertop.

You can install it two ways:

  1. For a one-hole installation, mount it directly onto the countertop.
  2. Use a plumbing plate to cover up the additional holes in the faucet.

Installing the Single Handle Faucet with Sprayer

The hardware already has the diverter and hot and cold lines within the faucet.

Check your instruction manual to see how best to connect the diverter to the sprayer.


  1. For a one-hole connection, you do not need any plumber’s covers on the countertop.
  2. For more than one hole, you’ll need plumber’s covers to seal off the other holes.
  3. Reinforce the space between the gaps in the countertop with a gasket.

Secure the Faucet. The parts include:

Mounting bolts and screws


The mounting pieces will connect to the shaft under the sink. The washer is placed against the countertop and reinforced with the nuts and bolts.

  • Position the gasket under the plumber’s plate.
  • Slip it over the pipelines and into the shaft of the faucet.
  • Place it on the mounting surface.
  • Cover the two holes that are not needed.

Reach under the sink and fasten the nut just beneath the surface.

Fasten it to the mounting screws and make sure it lines up evenly.

When it is aligned, give it another turn to hold it firmly in place.

Install the Hot and Cold Valves

In the single handle faucet, both lines are within the spout. It may also have flexible supply lines within the hardware.

Check the marks to identify the hot and cold taps. Just attach each line to the appropriate water supply valves in the connections.

Attach the Water Supply Lines

Once the lines are in place, attach the other end to the water valves coming out of the wall.

Wrap a piece of tape and twist it to the right all around each thread.


  • The cold water line is on your right, the hot on our left.
  • Fasten each bolt and reinforce it with a wrench.
  • Take your time and fasten the pipe to the valve to minimize any damage to the line.

How to Install the Sprayer

You can either opt to install a separate sprayer or a pullout model. Make sure to choose the sprayer to fit the hole or holes in your sink.

  1. Thread the sprayer hose into the hole, with the gasket inserted into the shaft.
  2. Reach under the sink and attach the bolt into the shaft.
  3. Position it against the underbelly of the countertop. Reinforce it with an extra pair of hands if necessary.

With one hose already connected to the sprayer head, thread the sprayer into the hose guide. Attach the other end of the diverter to the tube.


Some sprayers may attach differently. The diverter is the valve that is under the spout. Some may either slide or snap into position.

Single hand faucets have a component that allows you to connect the hose to the diverter quickly.

Test it Out

  1. Switch the water back on and at the hot and cold valves.
  2. Let the water run and check for any leaks.
  3. Tighten the connections until you’re satisfied any leak is gone. Over-tightening may damage the lines, be gentle.
  4. If leaks persist, switch off the water.
  5. Take off the nuts and bolts and wrap some more tape around the threads.
  6. Re-connect the lines, fasten them in place and turn the water on again.
  7. Check for any leaks before you flush the lines.

Flushing the Lines

After the new faucet is in place, let the water run to wash away any material left after installation.

Loosen the aerator, take it out and let the run water on it at full speed.

Switch off the water and re-install the aerator. You’re all done!


A new faucet or a single handle faucet with sprayer is a convenient, trendy and functional addition to your kitchen sink. Start by selecting the best hardware and attachments for your specific needs.

Follow your manual and have your tools on hand to make your job effortless and hassle-free. In no time, your kitchen will look almost new.
