How to Fix a Kitchen Faucet: A Step-By-Step Guide

It is very annoying to hear water dripping sound of a kitchen faucet. And it is more annoying to discover slippery and rusty surroundings of the faucet.

Many of you have thought to kick out this ‘water-water everywhere’ problem for good. You may have called a plumber to fix this issue.

But has it ever crossed in your mind that you can fix your kitchen all by yourself, like a pro handyman? Well of course it did! But you don’t know how?

That's why I'm here to give you a complete step-by-step guideline on how to fix a leaky kitchen faucet with two handles, with single handle and a spout as well.

Before starting, you need to know what problem can cause your faucet leaking water. You need to determine the problem and act according to it.

Troubleshoot that can occur

  • If the water is dripping from your double handle faucet, you need to detect which stem is causing the leakage.
  • If water is dripping from the handle, you need to replace the stem of that handle. Same goes for a single handle faucet.
  • Oftentimes your faucet spout can cause the leakage too.

Now, it is much cleverer if you buy new parts instead of fixing the old parts. Because they may become rusty and damaged by the mineral substances.

Tools you need

Flathead screwdriver

This will be used to wield the bolts from the handle if it has a flat keyhole.

Crosshead screwdriver

This will be used to wield the bolts from the handle if it has a criss-cross keyhole.


Hex-keys are usually used to wield the bolts that have a hexagonal keyhole. This will be used to remove the spout section.


Here, it will be used to drive out the brass stem. If you have a plastic stem you just need to unscrew the top screw and the stem will come out. Do not use any wrench on it. This could break it.


They are to cover your draining hole of the sink. You don’t want any of the small parts to lost in that hole, right?

If you know how to replace a single handle kitchen faucet, you’ll know how to fix a double handle faucet too.

So, let’s dive in!

Replacing a single handle kitchen faucet

If the water is leaking either from the faucet or the handle, you’ll need to change the stem of the handle.

  • Step 1

Turn the main water supply off. Turn on the faucet to drain extra remaining of water. After that place the towel over the draining hole.

  • Step 2

Remove the aerator of the faucet to release any trapped air.

Sometimes, it is hard to remove the aerator because many mineral substances deposit around it. In such case, soak a towel into vinegar and wrap it around the faucet head covering the aerator. Leave it for an hour and the aerator will come off just by a twist.

  • Step 3

Remove the handle of the stem with the help of a screwdriver to unscrew the bolt over it. Use the screwdriver that fits in.

  • Step 4

For a plastic stem, it will come off right away when you unscrew the handle.

For a brass stem, you have to untie it using a wrench. Do not put too much pressure to cause it any damage.

  • Step 5

Take the faulty stem to any store, and the sells man will match you a new stem of the exact size. After that put everything into reverse process. Attach the aerator at the final step.  And you have fixed your faucet.

Replacing a double handle kitchen faucet

In this case, you have to follow the same removal procedure of the stem as you did for the single handle faucet. But how would you know which handle is faulty?

You know that one of the handles supply hot water and other one supplies cold water. If water leakage occurs in one of the handles, you know which one has to be replaced.

But if water leaks from the faucet, you have to find out which stem is faulty. For that,

  • Turn off the hot water supply key. If the leakage stops, then the hot water stem is faulty. If not, then the cold water stem is faulty.

Turn off both water supplies and start your work.

Repairing the spout

To fix kitchen faucet leaking from spout you need to replace its rubber seats, springs and O-ring.

  • Step 1

Using a wrench untie the faucet. At the end of the faucet, you'll find an O-ring. Replace it with the new one and put it back. Your spout s fixed.

However, if you have valve faucet, loosen the set screw with hex-key and take off the handle. Remove the cap, cam, washer and the ball as well.

Note the placement of the ball because later you have to line it up exactly as it was.

  • Step 2

Slide off the spout and replace the O-rings with new ones.

  • Step 3

Use hex-key to remove the rubber seats and the screw. And replace them with new ones.

  • Step 4

Replace the washer and cam individually and reassemble the rest of the faucet.


  • I strongly suggest to put the removed parts in sequence and take a picture of it. So that later, you can resemble them as per order without any confusion.
  • Before you attach the aerator, turn on the water for a while to drain off any substance.
  • Soak the aerator into vinegar before replacing it.
  • It is better if you buy new handles for your faucet.
  • Always buy an extra set of aerator, springs and rubber seats.


I have enlightened you about all the possible troubleshoots of kitchen faucet and gave you a step-by-step guideline on how to fix a leaky kitchen faucet with two handles to fix it. Some people prefer to change the whole kitchen faucet to give it a new look. And guess what? You also can do it all by yourself.
