Types of Faucets & How to Fix Their Leaks

In this guide, we’ll walk you through how to determine the type of faucet you have, provide step-by-step instructions to fix a dripping faucet based on its style, and explain why it’s important to address the problem at the first sign of trouble.

5 Steps to Fix a Leaky Faucet

The high-level process for fixing a faucet is relatively simple: shut off your water, remove the faucet handle, identify and repair the issue, and reattach the handle. However, the details of diagnosing and repairing the issue will depend on the type of faucet you have. A faucet repair kit can also facilitate the process, containing cartridges, o-rings, wrenches, springs, and whatever your faucet type should require.

Step 1: Determine the type of faucet

First, identify the type of faucet you have so that you will be able to troubleshoot and repair it (step 4). 

• Cartridge Faucet: If the faucet is a single handle that moves up and down to control flow and side-to-side for temperature, it’s likely a cartridge faucet. Some double-handle faucets also use cartridges, where each handle controls temperature.
• Double Handle Compression Faucet: These faucets have two separate handles, one for hot water and one for cold water. The handles are usually "twist-style" and may have visible rubber washers inside. These types of faucets often show wear as they rely on rubber washers to create a seal, which can lead to leaks over time.
• Double Handle Non-Compression Faucet: These types are similar to compression faucets with two separate handles for hot and cold water. However, instead of twisting, the handles will rotate with a smooth motion, and they may contain a cartridge, ball, or ceramic disk inside. These faucets don’t rely on rubber washers and are generally more durable than compression faucets.
• Single-Ball Handle Faucet: This faucet has one ball-shaped handle that moves in all directions to control the flow and temperature of the water. The handle will have a smooth, single action and is often used in kitchen faucets. The mechanism inside is a ball bearing that controls the flow and temperature, and it can be replaced if it wears out.
• Ceramic Disk Faucet: This type has a single lever or handle that controls both flow and temperature. The handle usually moves up and down for water flow and side-to-side for temperature. The interior mechanism contains ceramic discs that slide against each other, providing a tight seal. This type is often seen in modern, high-end faucets due to its durability.

Step 2: Shut off the Water

To turn off the water supply, you should be able to find a valve located under your sink. Twist the knob to an “off” position. If you cannot locate this, you can turn off your home’s water supply as you repair. 

Step 3: Remove the Faucet Handle

To remove the handle, see if you can locate the handle screw. It's usually hidden under a decorative cap or button on the top or side of the handle. You can pop this cap off using a flathead screwdriver. In some cases, there might be a second screw or fastener underneath the handle or inside the faucet body.

Step 4: Fix and/or Replace

Each type of faucet generally has a specific part that wears out, like washers, O-rings, or cartridges. You may find these individually at a hardware store or in a repair kit. Replace the worn part and reassemble.

Cartridge Faucet Repair

A worn-out or damaged cartridge is the most common cause for leaks. The cartridge controls the flow of water, and if it’s damaged, it may not create a proper seal, causing water to leak from the spout.

1. Remove the cartridge by pulling out the retaining clip and pulling it out of the valve body.
2. Inspect the cartridge for cracks or wear. Replace it with a new one if necessary.
3. Also, check the O-rings on the cartridge for any damage and replace if needed.

Double Handle Compression Faucet Repair

The most common reason for leaking is a worn-out washer or O-ring. These parts create a seal when you turn the handles, and if they’re deteriorated or cracked, water can leak out of the spout.

1. Remove the faucet stems to access the washers or O-rings.
2. Inspect and replace the washers or O-rings as needed.
3. Check the valve seat for any corrosion or wear, as this could also cause leakage.

Double Handle Non-Compression Faucet Repair

A worn-out valve seat or damaged valve seals is typically responsible. The valve seals control water flow, and if they degrade, water can leak out of the spout.

1. Remove the valve components and check the valve seals for damage or wear.
2. Replace any worn-out seals or O-rings.
3. Check the valve seat for any signs of damage, like corrosion, and replace it if needed.

Single-Ball Handle Faucet Repair

The most common cause of leaking is a damaged ball valve or worn-out O-rings around the ball. These seals prevent water from leaking when the faucet is off.

1. Pull out the ball assembly and inspect the O-rings and seals.
2. If the O-rings are cracked or worn, replace them.
3. If the ball valve is damaged, it may need to be replaced.

Ceramic Disk Faucet Repair

Leaks in ceramic disk faucets are often caused by worn ceramic discs or damaged seals. The ceramic discs control the water flow and can wear down over time, allowing water to leak.

1. Remove the cartridge assembly to access the ceramic discs.
2. Inspect the ceramic discs for cracks or damage.
3. Clean any mineral buildup and replace the discs or seals if necessary.

Step 5: Reattach Faucet Handle

Screw the faucet handle back on and turn on the water. Your sink should be functioning correctly again.

Who to Call if You Need Help?

As you can see, leaky faucets are usually caused by simple wear and tear of parts that form seals in the faucet. Most leaks can be fixed by replacing washers, O-rings, cartridges, or other worn-out components. If the faucet is old or if the repairs are extensive, it might be worth considering replacing the faucet entirely.

The Importance of Fixing Home Issues

Leaky faucets are more than an annoying dripping noise. They can lower the faucet’s water pressure, increase your water bills, and be a magnet for pests like roaches and rodents. If water pools, it can also be a recipe for mold and create potential health risks.
