What Causes Kitchen Sink Faucet Leakage
Cartridge, compression, ceramic disc, and ball type are the four most common types of faucets. The compression faucet consists of rubber washers that seal that valve. With time and constant use, it can depreciate and may require maintenance. The remaining types of faucets have O-rings, cartridges, or sometimes neoprene seals that can be caused by the drip.
You need to focus on other aspects of these faucets. Because of the frequent use, wear, and tear at the base is common too. It can cause small gaps at the base of the faucet and the sink. This can also lead to a faucet washer being broken or worn out, chances are the watertight seal is not workable any longer. Faucets also have a valve, if corroded or rusty, water leakage is one of the common problems besides metal particles in the water. The purpose of the valve seat is to compress the mechanism and keep the tight seal on the spout but with the rust, it causes water dripping.

How to Fix a Dripping Kitchen Faucet According to Type
Before you begin to fix the leaking kitchen faucet, it’s important to take notice of the type of faucet you have in your kitchen. It can be a cartridge faucet, compression, ceramic disc, or a ball-type faucet in the kitchen that is leaking.
Although the basic parts of a faucet are the same more or less, the cause of leakage can vary depending on the distinct parts of the faucet. So to fix the dripping faucet you will need to identify the faucet and type and collect the tools.
1. Cartridge Faucet
The cartridge controls the water flow in a faucet. If it is worn out O-rings can wear up and cause water leakage. It might be possible that you have a leaky cartridge faucet.
Steps to Fix Leaky Cartridge Faucet
- Start by removing the decorative cap handle, loosening the screw, then tilting back and pulling it off.
- You will need to use needle-nose pliers to remove the threaded retaining clip. It holds the cartridge in its place.
- Take off the spout to remove the old O-rings. You can use a utility knife. It is recommended to use heat-proof plumber’s grease to install new O-rings.
- Buy a new cartridge similar in length to the old one. Make sure to match the stem handles.
2. Compression Faucet
These are most common in older homes. Compression faucets use a washer compressed by tightening the faucet handle. Over time when the washer wears out, it can cause a dripping kitchen faucet.
Steps to Fix Leaky Compression Faucet
- Take a small screwdriver to remove the decorative cap on the faucet handle. You will be able to see the screws now.
- Remove the screws using the small screwdriver and pull off the handle.

This faucet type is a bit complex and it can be time-consuming to fix the dripping faucet. You may even need to buy a new replacement kit to put together all the parts properly.
Steps to Fix A Leaky Ball-Type Faucet

6 Steps to Fix a Leaky Kitchen Faucet with One Handle
Did you know within an hour you can fix a leaky kitchen faucet for good? Follow these steps carefully.
1. Learn the Basics of Kitchen Sink Faucet
- If you are thinking about how to fix a leaky kitchen faucet, then you need to start with the basic mechanism.
- Before beginning the repairing process, pile up the tools and equipment before you.
- Arrange them step by step so that you know which tools to use first and so on. Every kitchen faucet is different, so study the model and design installed in the kitchen.
2. Turn Off the Water Supply
- Whenever you are working on the kitchen faucet, always shut the water supply. The same rule applies when fixing the leaky kitchen faucet.
- Now, you need to turn off the valve under the sink. They are usually covered with the base cabinet. Once you are confident, the water flow is broken, pat the surface dry.
3. Use a Wrench to Remove the Faucet’s Handle
- When removing the kitchen faucet handle, understand how it was assembled beforehand.
- You will be working anticlockwise to remove it. If the faucet is single-handle, the cartridge is under it.
- To remove it, first, pry off the decorative yet worn-out plastic cap using a wrench. Now the holes for hot and cold water will be exposed.
4. Take Out the Bonnet
- After the cartridge, you need to remove the bonnet. But do it carefully so as not to scratch the chrome over the cartridge.
- For this purpose, it’s recommended to use slip-joint pliers. They look like needle-nosed pliers and best work for U-shaped retainer clips.
- After you’ve taken them out, line them up aside so that nothing is mixed up.
5. Install New Cartridge
- At this stage, you will find some resistance from the rubber O-rings in the form of suction.
- When replacing the kitchen sink handle, do not twist the unit, instead, slide it straight. If it’s a dripping spout issue, then the cartridge is most likely the culprit behind the leak. However, fit the retainer clip and do so snuggly.
6. Reassemble Faucet Handle
- Now you can reassemble the faucet in reverse. Once done, make sure that all parts of the faucet align and nothing is loosened up.
- Turn on the water supply to check for any further leakage. If you find none, then viola!
6 Steps to Fix a Leaky Kitchen Faucet with Two Handles
Most two-handled kitchen faucets are commonly found. Each faucet handle carries a separate cartridge for hot and cold water. To fix a traditional leaking two-handle kitchen faucet, follow these steps.
1. Turn Off the Water Supply
- Before fixing any under-the-kitchen sink leaks, shut off the valves to disconnect the water supply. Within the exterior cover of the handles, is a football-shaped handle (lever).
- Rotate it clockwise until the water stops flowing. In case you have levers (but no knobs) you will need to rotate the levers. They must be perpendicular to the water pipes.
- In dire circumstances, if water keeps flowing, it’s best to shut off the main valve. Wait for the water to drain out first.
2. Remove the Faucet Handle for Repair
- Before removing either or both handles of the kitchen faucet, examine them for leakage.
- You may find set screws on the side of the handles. But sometimes a decorative cap is used to conceal them.
- Most faucets also have a removable lever that you can use to unscrew the base. For this purpose use a screwdriver with an Allen wrench.
- Do not twist it, instead pull just straight up and remove it from the faucet.
3. Unscrew Retaining Handle’s Nut
- With the help of the pipe wrench or tongue-and-groove pliers, loosen up the cartridge retaining nut.
- Unscrew the nuts and remove them. In case the faucet has a brass screw you can reuse it for the new cartridge. Because they are old-fashioned trends and may not be easy to locate in the market.
4. Remove Old Cartridge
- You have to remove the old cartridge carefully to remember the direction.
- Remember, that most cartridges consist of one or two tabs that snug the faucet body. Pull it out straight and remove the cartridge. You can also grab the shaft, if required, with the pliers.
5. Install a New Cartridge
- Before you do anything else, get a new cartridge from the store. They usually include a new rubber O-ring. If you want to, O-rings can be greased too for easy insertion inside the cartridge.
- You will also need to replace the brass screw on the top of the cartridge if needed. Align the cartridge with tabs and the faucet body.
6. Reattach Faucet Handle
- Once the new cartridge is secured, tighten the nut counterclockwise.
- Test the faucet for any further leakage. If none is found, then you are good to go.
