How to Change a Leaky Faucet
As a homeowner, I've experienced the frustration of the soothing sound of water turning into the incessant dripping of a leaky faucet. It's not only an annoyance but can also lead to higher water bills, unsightly water stains, and the dreaded possibility of mold growth. The good news is that you don't need to be a plumbing expert to tackle this issue. In this detailed guide, I'll take you through a step-by-step process on how I successfully changed a leaky faucet, and you can too.
Why Do Faucets Leak?
When confronted with a leaking faucet, it's crucial to grasp the underlying factors contributing to this common household issue. Faucet leaks can be attributed to a variety of reasons, each of which deserves a closer examination:
Worn Out O-ring
One of the primary culprits behind faucet leaks is the diminutive yet indispensable O-ring. Located on the stem screw, this tiny disc plays a pivotal role in holding the faucet handle securely in place. Over time, the O-ring can wear out or become loose due to repeated use, leading to pesky leaks.
Corroded Valve Seat
A critical junction in the faucet system, the valve seat connects the faucet to the spout. Unfortunately, this crucial component isn't immune to the effects of corrosion, which can develop over an extended period. Corrosion can gradually erode the valve seat, creating an environment conducive to leaks.
Worn Out Washer
With each use of the faucet, the washer experiences significant pressure as it is pressed against the valve seat. This repetitive action, though essential for controlling water flow, can also result in the gradual deterioration of the washer. Consequently, a worn-out washer becomes susceptible to causing leaks.
Improper Installation
Even the most well-designed faucets can fall victim to leaks if not installed correctly. The washer's proper installation is paramount to prevent leaks. An incorrectly installed washer can create gaps or inconsistencies in the seal, allowing water to escape and manifesting as a leak.

Tools You'll Need
When it comes to tackling the task of fixing a leaky faucet, it's vital to have the right tools at your disposal. A well-prepared toolkit can make the repair process more efficient and help you achieve a successful outcome. Here's a detailed list of the tools you'll need:
- Adjustable Wrench: An adjustable wrench is an indispensable tool for faucet repair. It enables you to tighten or loosen various nuts and bolts with ease, allowing for the disassembly and reassembly of faucet components.
- C-Wrench: A C-wrench, also known as a basin wrench, is specifically designed for reaching and tightening nuts that are often located in tight spaces beneath the sink. This tool is essential for loosening and securing the nuts that hold the faucet in place.
- Philips and Flat-Head Screwdrivers: These two types of screwdrivers are versatile and necessary for working on different types of faucets. Philips screwdrivers are suitable for screws with a cross-shaped recess, while flat-head screwdrivers are used for screws with a single straight-line slot.
- Replacement Parts (such as O-rings and washers): To address the root causes of faucet leaks, you'll likely need replacement parts. These can include O-rings, washers, and other components specific to your faucet model. Having the right replacement parts on hand ensures you can complete the repair without delays.
- Penetrating Oil (e.g., WD-40 or CLR): Penetrating oil is invaluable for loosening corroded or stuck faucet parts. When components have been in place for a long time, they may be challenging to remove. Applying penetrating oil helps break down rust and corrosion, making disassembly easier.
- Old Rag or Cloth: Keeping a rag or cloth handy is essential for cleaning up excess water and preventing it from seeping into your workspace. It also provides a surface for placing disassembled faucet parts to keep them organized and prevent damage.
Identifying Your Faucet Type
Before embarking on any faucet repair or replacement project, it's essential to accurately identify the type of faucet you're dealing with. Faucet types vary in design and operation, and understanding these distinctions is fundamental to the successful execution of your plumbing task. Let's delve into the details of the four primary faucet types:
Compression Faucets
Recognized by their dual handles—one for hot water and one for cold—compression faucets operate on a basic yet effective principle. When you turn the handles, they compress a rubber or neoprene washer against the valve seat. This action stops water flow by blocking the passage. Due to their design, compression faucets are more susceptible to leaks over time, typically from the washer wearing out.
Ball Faucets
Ball faucets are characterized by a single lever handle that pivots in all directions. Beneath this handle, you'll find a round, dome-shaped ball bearing with multiple openings. As you move the handle, the ball rotates and aligns with different ports within the faucet body, regulating both water flow and temperature. Ball faucets are known for their durability and ease of use.
Ceramic-Disk Faucets
Ceramic-disk faucets are recognized for their exceptional longevity and precise control over water flow and temperature. They can feature either a single lever or dual handles. Instead of rubber washers, ceramic-disk faucets employ two ceramic cylinders with tight tolerances. When the handle is turned, these ceramic disks move relative to each other, allowing for the desired water flow and temperature adjustment. These faucets are less prone to leaks and are known for their reliability.
Cartridge (Sleeve) Faucets
Cartridge faucets share similarities with ceramic disk faucets but utilize a cartridge for flow and temperature regulation. Like ceramic disk faucets, they can have either a single lever or dual handles. The cartridge contains a series of O-rings and seals, and when you turn the handle, it moves the cartridge to control water flow and temperature. Cartridge faucets are renowned for their ease of maintenance and robustness.
Step-by-Step Guide to Changing a Leaky Faucet
Tackling a leaky faucet requires a systematic approach to ensure a successful repair. Here's a detailed, step-by-step guide to changing a leaky faucet, covering various faucet types and potential issues:
Step 1: Shut Off the Water Supply
- Locate the water supply valves positioned beneath the sink. If you're unable to find them or they're absent, turn off the main water line for your entire home to ensure water flow to the faucet is completely halted.
- To release any remaining pressure in the plumbing system, turn on the faucet and allow any trapped water to drain out.
Step 2: Remove the Handle (varies by faucet type)
- Compression & Cartridge Faucets: Begin by removing the decorative cap covering the handle. A flat-head screwdriver is typically handy for this task. Once the cap is off, you'll reveal a screw beneath it. Unscrew and remove the handle from the faucet.
- Ball Faucets: Loosen the set screw securing the handle in place. Once the set screw is loose, carefully remove the handle from the faucet.
- Ceramic-Disk Faucets: Gently push the faucet handle backward to access the screw cover. Remove this cover to expose the screw underneath. Unscrew and lift off the handle.
Step 3: Identify and Fix the Problem
- Compression Faucet: Utilize a wrench to remove the packing nut. Afterward, unscrew the stem and inspect the O-ring and washer. Replace any worn-out components with new ones to address the issue.
- Ball Faucet: Remove the cap and collar with the assistance of a wrench. Loosen the faucet cam, and then remove the washer and ball. Examine these parts closely and replace any that show signs of wear and tear.
- Cartridge Faucet: Start by removing the retaining clip. Then, pull the cartridge up so that it stands upright. If the cartridge is worn out, it's essential to replace it with a new one.
- Ceramic-Disk Faucet: Push the faucet handle back to access the escutcheon cap. Remove this cap and proceed to unscrew and remove the disk cylinder. Inspect the neoprene seals, and if they're worn out, replace them. Additionally, check the cylinder openings for any clogs and clean them as necessary.
Step 4: Reassemble the Faucet
After replacing the problematic components with new ones, reassemble the faucet in the reverse order of disassembly. This typically involves carefully following the steps outlined earlier but in reverse, ensuring everything is securely fastened and aligned.
