How to Fix a Leaky Faucet: A Step-by-Step Guide

A leaky faucet is more than just an annoyance; it wastes water and can lead to higher utility bills. Fortunately, many faucet leaks are easily fixable with basic tools and a little know-how. This guide will walk you through troubleshooting and fixing common faucet leak issues. However, if you’re uncomfortable working with plumbing, it’s always best to call a qualified plumber.

Identifying the Source of the Leak

Before you begin, pinpoint the exact location of the leak. This will help you determine the necessary repair steps. Common leak sources include:

• The faucet handle: Leaks here often indicate worn-out O-rings or cartridges.
• The spout: Leaks from the spout usually point to a problem with the O-ring or washer within the spout assembly.
• The base of the faucet: Leaks at the base may signal a loose connection or a problem with the faucet’s mounting hardware.

Tools You’ll Need

Before you start, gather the necessary tools. The specific tools may vary depending on your faucet type, but you’ll likely need:

• Screwdrivers (Phillips and flathead)
• Adjustable wrench
• Pliers
• Basin wrench (for hard-to-reach nuts under the sink)
• Replacement parts (O-rings, washers, cartridges – these are specific to your faucet; check the manufacturer’s instructions or take a picture of the parts to take to the hardware store.)
• Towels or rags
• Bucket or container to catch water

Fixing a Leaky Faucet Handle

This is a common problem. The steps may differ slightly depending on whether you have a compression faucet (separate hot and cold handles) or a cartridge faucet (single handle).

Compression Faucets

1. Turn off the water supply: Locate the shut-off valves under the sink for both hot and cold water. Turn them clockwise to shut off the water supply.
2. Remove the handle: Use the appropriate screwdriver to remove the handle screw(s). Carefully remove the handle.
3. Access the packing nut: Once the handle is removed, you’ll see a packing nut. Loosen this nut using the adjustable wrench.
4. Replace the O-ring and packing: Remove the old O-ring and packing, and replace them with new ones.
5. Reassemble: Tighten the packing nut, replace the handle, and turn the water back on.

Cartridge Faucets

1. Turn off the water supply: As above, shut off the water supply under the sink.
2. Remove the handle: This usually involves removing a retaining clip or screw.
3. Remove the cartridge: The cartridge is typically held in place by a retaining nut. Unscrew this nut and remove the cartridge.
4. Replace the cartridge: Install the new cartridge, making sure it’s seated correctly.
5. Reassemble: Reassemble the faucet, turn the water back on, and check for leaks.

Fixing Leaks from the Spout

Leaks from the spout usually involve replacing the O-ring or washer in the spout assembly. This often requires removing the spout and accessing the internal parts. Consult your faucet’s manufacturer’s instructions or search for online tutorials for your specific faucet model, as the process can vary significantly.

Addressing Leaks at the Faucet Base

Leaks at the faucet base often indicate loose connections or damaged mounting hardware. This usually requires tightening the mounting nuts under the sink. Again, if you are uncomfortable working underneath the sink, call a qualified plumber.

Conclusion

Fixing a leaky faucet can save you money and water. While the specific steps vary depending on the faucet type and the source of the leak, understanding the basics allows you to tackle many common problems yourself. Remember to always turn off the water supply before starting any repairs. If you’re unsure about any step, don’t hesitate to consult a professional plumber.
