Dealing with a persistent leaky faucet can be frustrating, but it’s a common plumbing issue that homeowners often face. In our 15 years installing… Whether you have an older globe valve faucet or a modern ceramic disc model, understanding the root causes and learning how to properly repair and maintain your fixtures can save you from the hassle of constant drips and potential water damage.
Now, this might seem counterintuitive…
Plumbing Basics
Types of Faucets
Faucets come in various designs, each with its own internal components and repair requirements. The most common residential faucet types include:
- Compression Faucets: These use a rubber washer that compresses against a valve seat to stop water flow. They are typically found in older homes.
- Cartridge Faucets: These have a removable cartridge that contains all the working parts, making repairs simpler.
- Ball Faucets: These use a hollow ball mechanism to control water flow and direction.
- Ceramic Disc Faucets: These feature durable ceramic discs that slide against each other to turn the water on and off.
Knowing the type of faucet in your home is the first step in diagnosing and repairing a leak.
Faucet Components
Regardless of the style, all faucets share some basic internal components:
- Washers: Rubber gaskets that create a seal to prevent leaks.
- Stems: The moving parts that turn the faucet on and off.
- Cartridges: Removable units that contain the valves, springs, and other internal workings.
- Valve Seats and Springs: Parts that open and close to control water flow.
- O-Rings: Small rubber seals that prevent leaks around movable parts.
Understanding these key components will help you determine the root cause of a leak and select the right replacement parts.
Identifying Leaks
Pinpointing the Source
When dealing with a leaky faucet, it’s crucial to identify the exact source of the leak. Is the drip coming from the faucet body, the handle, or the base where it meets the sink? Carefully inspect the entire fixture to locate the origin point.
Assessing the Damage
Once you’ve pinpointed the leak, take a closer look to assess the extent of the issue. Is the leak caused by a worn-out washer, a damaged cartridge, or a corroded valve seat? Identifying the specific problem will determine the necessary repair steps.
Faucet Repair Tools
Essential Tools
Gathering the right tools for the job is key to successfully repairing a leaky faucet. At a minimum, you’ll need:
- Adjustable Wrench: For loosening and tightening faucet components
- Pliers: Helpful for gripping and removing small parts
- Screwdrivers: Both flat-head and Phillips head are typically required
- Basin Wrench: Allows you to access the faucet’s supply lines and mounting hardware
- Replacement Parts: Washers, O-rings, cartridges, or stems, depending on your faucet type
Safety Considerations
When working on plumbing repairs, it’s essential to take precautions to protect yourself and your home. Always shut off the water supply to the faucet before beginning any work, and have towels or a bucket on hand to catch any water that may spill during the process.
Replacing Washers
Removing the Old Washer
If your faucet is leaking from the spout, the issue is likely due to a worn-out rubber washer. Begin by shutting off the water supply and removing the faucet handle. Use pliers or a wrench to unscrew the retaining nut or valve stem, then carefully extract the old washer.
Installing a New Washer
Once the old washer is removed, simply insert a new replacement washer, ensuring it is properly seated and aligned. Reassemble the faucet in reverse order, taking care not to overtighten any components. Turn the water back on and test the faucet for any lingering leaks.
Replacing Cartridges
Cartridge Identification
Many modern faucets use a removable cartridge system, which can simplify repairs. To replace a leaky cartridge, you’ll first need to identify the specific model installed in your faucet. This information is often printed on the cartridge itself or can be found in the manufacturer’s documentation.
Cartridge Replacement Process
With the water supply turned off, remove the faucet handle and any retaining nuts or caps to access the cartridge. Gently pull out the old cartridge, taking note of its orientation. Insert the new replacement cartridge, ensuring it is properly aligned, then reassemble the faucet.
Replacing Valves
Valve Types and Selection
In some cases, a leaky faucet may be caused by a damaged or corroded valve seat or spring. Depending on your faucet model, you may need to replace the entire valve assembly, which consists of the valve seat, spring, and related components.
Valve Replacement Steps
Begin by shutting off the water supply and disassembling the faucet to access the valve. Use a basin wrench to loosen and remove the valve, then take it to a hardware store to find a compatible replacement. Install the new valve, ensuring it is properly seated and tightened, then reassemble the faucet.
Maintenance and Prevention
Regular Inspections
To avoid the hassle of frequent faucet repairs, it’s essential to maintain your fixtures through regular inspections. Periodically check for any signs of wear, such as drips, low water pressure, or unusual noises, and address issues before they become more significant problems.
Proactive Measures
In addition to regular inspections, take proactive steps to extend the life of your faucets. This includes regularly cleaning the aerator, applying plumber’s grease to moving parts, and shutting off the water supply when the faucet is not in use.
Troubleshooting Tips
Common Faucet Issues
While leaks are the most common faucet problem, you may also encounter other issues, such as poor water flow, difficulty turning the handle, or strange noises. These can often be traced back to worn-out washers, damaged cartridges, or mineral buildup in the internal components.

In many cases, homeowners can successfully repair leaky faucets themselves by following the steps outlined in this article. However, if you encounter persistent or complex issues, it’s best to consult a professional plumber. Experienced technicians have the specialized tools and expertise to diagnose and fix even the most stubborn faucet problems.
