How to Fix a Leaking Tap: A Step-by-Step Guide

Tired of the annoying "drip, drip, drip" coming from your tap? A leaking tap is not only a nuisance but can also lead to wasted water and higher bills. 

While calling a plumber might seem like the easiest solution, a leaking tap repair is often a straightforward DIY job. With the right tools and a bit of patience, you can repair the leak yourself, saving both time and money. 

This guide will walk you through everything you need to know to fix a leaking tap, whether the issue is with the spout, handle, or elsewhere. 

Let’s get started!

Let's Dive In: Your Guide to Fixing a Leaking Tap

A leaking tap repair is one of the most common plumbing issues you’ll encounter at home, but fortunately, it’s also one of the easiest to fix. Before getting your hands dirty, it’s essential to understand the source of the leak, gather the right tools, and determine whether it’s a simple repair or something more serious. 

This section will walk you through everything you need to know to tackle a leaking tap with confidence.

1. Identifying the Problem: Where’s the Leak Coming From?

Before you can fix a leaking tap, it’s important to identify the exact source of the leak. Different types of leaks require different solutions, so knowing where the water is coming from will help guide you toward the right leaking tap repair.

• Leaky Spout: If you notice water continuously dripping from the spout, even when the tap is turned off, this is often caused by a worn washer or valve seat. These components are responsible for controlling the flow of water, and when they wear down or become damaged, they can no longer create a watertight seal, resulting in leaks. Replacing the washer or repairing the valve seat can usually fix this issue.
• Leaky Handle: If water is pooling around the base of the handle, it’s a sign that the O-ring or cartridge inside the tap is worn out. O-rings and cartridges help maintain a tight seal within the tap. When these components are damaged, water can seep through and cause leaks. Replacing the O-ring or cartridge should resolve this problem.
• Leaky Base: A leak at the base of the tap, where it connects to the sink, is often due to a worn-out seal or improper installation. In this case, you’ll likely need to replace the seals or gaskets to stop the water from escaping at the base.

Tip: Accurately identifying where the leak is coming from will help you purchase the correct replacement parts and ensure a quicker, more effective repair.

2. Gather Your Tools: Equip Yourself for Success

Before tackling your leaking tap, it’s essential to gather the right tools and materials. Being well-prepared ensures a smoother, faster repair and prevents interruptions in the process. Having everything on hand allows you to focus on fixing the leak efficiently without scrambling for tools mid-job.

Here’s a list of essential tools for a leaking tap repair:

• Adjustable Wrench: This versatile tool is ideal for loosening and tightening nuts, bolts, and other fittings on your tap. It’s especially useful for unscrewing the spout or removing internal components during a repair.
• Pliers: Pliers are perfect for gripping and turning smaller components like washers or O-rings. They provide the necessary control to carefully remove or replace parts without damaging them.
• Screwdriver: You’ll need a screwdriver to remove screws holding the tap handle or other parts in place. Depending on your tap, you may need a flathead or Phillips-head screwdriver, so it’s best to have both types available.
• Basin Wrench: This specialised wrench is ideal for working in tight spaces, such as the area under your sink. It allows you to reach and loosen the nuts that hold the tap in place with ease.
• Teflon Tape: Wrap Teflon tape around threaded connections to create a watertight seal. This is particularly important when reinstalling parts or dealing with leaks at joints.
• Replacement Parts: Depending on the cause of the leak, you may need new washers, O-rings, or a cartridge. It’s always a good idea to bring the old parts with you to the store to ensure you purchase the correct replacements.

Tip: Before starting, always turn off the water supply to avoid a messy flood. The shut-off valve is typically located beneath the sink, and it’s essential to close it before disassembling your tap.

3. Fixing a Leaky Spout: A Common Culprit

One of the most frequent causes of a leaking tap is a worn-out washer in the spout. Over time, washers degrade, leading to leaks that can waste a significant amount of water if not addressed. Fortunately, fixing a leaky spout is a relatively simple task, requiring only a few tools and some replacement parts. Follow these steps to resolve the issue:

Steps to Fix a Leaky Spout:

1. Turn Off the Water Supply: Before you begin, locate the shut-off valve under the sink and turn it off to stop the flow of water. This prevents any mess while you work on the tap.
2. Remove the Handle: Using a screwdriver, remove the screw that holds the tap handle in place. Once the screw is removed, gently pull the handle off to expose the internal components.
3. Remove the Spout: Use an adjustable wrench to unscrew the spout from the tap body. Be cautious not to overtighten or force it, as this can damage the spout or tap fittings.
4. Replace the Washer: Inspect the washer for signs of wear or damage. A worn or hardened washer is often the source of the leak. Replace it with a new washer of the same size. Make sure the replacement washer fits securely in the spout.
5. Reassemble the Tap: Once the new washer is in place, reattach the spout and secure the handle. Tighten all components carefully, ensuring everything is fitted snugly.
6. Turn On the Water: Turn the water supply back on and test the tap by turning it on and off. If the leak persists, the issue could be with the valve seat, which may require cleaning or replacement.

By following these steps, you can often stop a leaking spout and save water and money in the long run.

4. Fixing a Leaky Handle: A Trickier Fix

A leaking handle is often a sign that the O-ring or cartridge inside the tap is worn or damaged. This type of leaking tap repair can be slightly more complex than fixing a leaking spout, but it's still manageable for DIYers with the right tools. Follow these steps to fix a leaky handle and restore your tap to perfect working order.

Steps to Fix a Leaky Handle:

1. Turn Off the Water Supply:
   Before starting, shut off the water supply to prevent any unwanted spills. The shut-off valve is typically located beneath the sink.
2. Remove the Handle:
   Use a screwdriver to remove the screw holding the handle in place. Once the screw is removed, gently pull the handle off to reveal the cartridge or O-ring inside.
3. Remove the Cartridge or O-ring:
   Using pliers or a specialised tool, carefully remove the damaged part. Make sure to note the exact position and orientation of the part before taking it out, as this will help with reassembly.
4. Replace the Cartridge or O-ring:
   Install the new cartridge or O-ring, ensuring it’s seated properly and fits snugly. Proper installation is key to preventing further leaks.
5. Reassemble the Tap:
   Put the handle back in place and tighten all screws securely. Ensure that everything is firmly reassembled before testing.
6. Turn On the Water:
   Turn the water supply back on and test the tap. If the handle no longer leaks, your repair is complete!

Tip: Always use genuine replacement parts specific to your tap brand and model to ensure a proper fit and long-lasting repair.

5. Fixing Other Types of Leaks: When It’s Time to Call a Professional

While many leaking tap issues can be repaired with basic DIY skills, some problems are more complex and may require professional assistance. Below are two examples of issues that are harder to fix on your own:

• Cracked Tap Body: If the body of the tap is cracked or damaged, it cannot be repaired by replacing parts. In this case, you’ll need to replace the entire tap.
• Leaking Pipes: If water is leaking from the pipes beneath your sink, the problem is more serious and will likely require a plumber. Pipe leaks can lead to extensive water damage if not fixed quickly.

If you're not confident in your DIY skills or if the leak persists after your repairs, it’s time to call a professional plumber.

Tip: For more serious or complicated leaks, contact a plumber like Sewer Surgeon to get the job done quickly and efficiently. This ensures the problem is fixed properly without causing further damage.
