Has your kitchen faucet sprung a leak and your tape job just isn’t cutting it? Today, I’m going to show you how you can save some money replacing your kitchen faucet in less than an hour.

Step 1: Watch the Video!!

Step 2: Recognize Failed Rig Job

So, your faucet is broken and you have no choice but to fix it. With a few common tools, this is an easy fix that anyone can do.

Step 3: Buy a New Kitchen Faucet

Buy a new kitchen faucet. I purchased a Caldwell by Moen.

There are a few different tools you can use, but I used an old pair of VISE-GRIP locking pliers for the entire project.

Before you get started replacing the sink, clear out everything from underneath your sink. It gets crowded in there and by far the hardest part of the job.

In the box you’ll get the faucet, paperwork, an instruction manual and the parts.

Step 4: Turn Off Hot and Cold Water to the Faucet

To start the process, turn off both the hot and cold water to the faucet. If you don’t you will soon find out why. Check the faucet to make sure that they are completely off.

Step 5: Unscrew Hot and Cold Connections From the Faucet

The type of faucet that you will buy will depend on how many holes are in your sink. This is a 4-hole sink and the most common used in kitchens.

Start by unscrewing both the hot and cold connections from the faucet. Have a rag towel on hand for any extra water that may leak out….and it probably will.

Step 6: Remove the Side Spray

Disconnect the spray hose connection from the center pipe under the sink. I then unloosed the hose guide nut and unscrewed the hose guide from the top.

Remove the sprayer.

Your old faucet may have a metal sink bracket that you will also have to remove.

Step 7: Remove the Old Faucet

Once you have disconnected both the hot and cold water supply lines to the faucet and the side spray hose, then just lift the old sink up and out of the sink.

Step 8: Insert the New Hose Guide

Insert the new hose guide. From under the sink, thread on the hose guide nut. This is where super long arms or a helper comes in handy.

Alternatively, you could temporarily tape the hose guide to the sink to keep it in place while you start threading the nut under the sink.

Step 9: Insert Side Spray

After you have tightened the hose guide into place, insert the side spray into the hose guide and feed the hose under the sink.

Step 10: Assemble New Sink

Remove the new faucet from the box and screw on the spout.

Step 11: Add Gasket and Connector

Add the deck plate gasket to the bottom of the faucet and click on the quick connect adapter. Click in the side spray hose into the bottom of the quick connect adapter.

Step 12: Install the New Faucet

Insert the new faucet into the holes in the sink and line it up. Make sure the brand name of the new faucet is pointing towards you.

Step 13: Screw on Mounting Nuts

Screw on both sink mounting nuts to the hot and cold water pipes from the faucet.

Step 14: Remove Old Supply Lines

Remove the old supply lines if they are too short. Mine were so I had to purchase new supply lines. Commonly, they come in PVC and Stainless Steel. I purchased (2) 20” PVC faucet supply lines for about $6 each.

Step 15: Attach Faucet Supply Lines

Attach the new faucet supply lines to the new faucet pipes hot and cold connections and the water inlet valves.

Optionally and probably recommended, you can add a few wraps of teflon tape for a better seal.

Step 16: Optional Upgrade

After you discover that one of your new supply lines is too short because you didn’t measure (me), go back to the hardware store and purchase longer lines. I upgraded to (2) 30” Stainless Steel faucet supply lines for a little over $8 each.

Step 17: Add Temperature Indicators

Add the red and blue temperature indicators to the faucet handles. The instructions showed prying them up with a screwdriver, but that is unnecessary and might scratch the finish.

Step 18: Turn the Water Back On

After ensuring that the new faucet is securely and evenly seated on your sink top, go ahead and turn the water valves back on.

Step 19: Enjoy Your New Faucet!

Proudly turn on your new kitchen faucet!

This project cost me around $100 and with the right tools can be accomplished in less than an hour.

    Leaking kitchen faucet


    Question 3 years ago on Introduction

    Dear Sir:

    Thank you very much for your posting. It is very helpful.

    Now I am having a leaking issue from my kitchen faucet but am not sure if is caused by leaky cartridge. I observed slow water leaking through cold water line under sink and no leaking found on other lines under sink such as hot water line. If the leaking is only related to cartridge, why is there no water on all lines under sink? I thought a leaky cartridge will cause water leaking to all water lines under sink. Is it right? In this case, I think replacing cartridge only may not solve my current leaking issue. Is it right? I guess my water leaking might occurred at the connection between cold water line and faucet. It is difficult to see and fix by just replacing cartridge. Could you please advise on my issue? I am trying to decide if I should replace cartridge or replace the whole faucet. Your help will be greatly appreciated!

    I am looking forward to hearing from you soon.

    Have a nice holiday!

    Hi Zhiming,

    99 times out of 100 a leak is a poor pipe joint and there are many causes,

    Such as Over tightening or Under tightening

    Or a little dirt in the threads

    Or too little Teflon tape ( You did get at least two full turns on the start of threads ?)..

    I am no plumber but every leak I have had was my error and going back up to three times and re-doing the pipe joints did eventually fix the problem..

    You should dry the pipes and using a bright light try to determine which connection is actually leaking !

    The water has a surface tension that hides the leak source "uphill" and only drips at a bend or obstruction below the pipe joint..

    If you have sensitive fingers, you can find the leak right after drying just by wet feel :-)

    Once I gave up and hired a Plumber !

    After that it was less expensive to buy new couplings..

    One other thing was to collect the drips in a bucket for a few days and wait for microscopic sand in the water to plug the slow leak for you :-)))
