A leaking mixer tap is often due to worn-out washers, damaged O-rings, or buildup of limescale inside the tap. Simple fixes like tightening loose components or replacing damaged parts can resolve most issues. Regular maintenance and prompt action can prevent more extensive damage and water wastage.
Introduction to Mixer Taps and Common Problems
Mixer taps are a modern convenience found in many homes, allowing you to blend hot and cold water with a single lever for the perfect temperature. However, as with any plumbing fixture, mixer taps can develop problems over time, the most common of which is leaking. A dripping or leaking mixer tap not only wastes water but can also be a sign of more significant wear and tear within the unit. Understanding the common causes of leaks and how to fix them can save you from expensive repairs and help extend the life of your mixer tap.
Why Do Mixer Taps Leak?
A leaking mixer tap is more than just an annoyance—it could be a symptom of deeper underlying issues. To effectively fix the problem, it’s essential to understand what causes these leaks. Mixer taps can develop leaks for a variety of reasons, each requiring a slightly different approach to remedy.
Common Causes of Leaks in Mixer Taps
One of the most common causes of a leaking mixer tap is the wearing out of internal components like washers, O-rings, or ceramic discs. Over time, these parts deteriorate due to regular use and the inevitable buildup of limescale and debris. Hard water can accelerate the degradation of these components, leading to more frequent leaks. A worn-out washer can result in a steady drip, while damaged O-rings may cause water to leak around the base of the tap or near the spout.
Another major culprit is the loosening of internal components. Sometimes, mixer taps leak simply because various parts, such as the valve or cartridge, have loosened over time. If left unchecked, these small issues can lead to more significant problems like water damage to countertops or cabinets.
Identifying the Source of the Leak
Before attempting any repair, it’s crucial to locate the source of the leak. Is water dripping from the spout, or is it pooling around the base of the tap? Is the leak coming from the handles when you turn the tap on or off? Identifying the exact area of the leak helps determine the specific component that needs fixing.
If the leak is coming from the spout, it’s often due to a worn-out washer or a faulty ceramic disc. However, if water is leaking around the base of the tap, the O-ring is likely damaged and needs replacement. Leaks from the handles usually point to problems with the valve or cartridge inside the tap.
Once you’ve pinpointed the source, you can decide whether you can fix it yourself or if it’s time to call in a professional.

Quick Fixes for a Leaking Mixer Tap
If you’ve identified the source of the leak, the next step is to fix it. Some common leaks can be easily repaired with basic tools and minimal plumbing knowledge.
Replacing a Washer or O-Ring
A worn-out washer or damaged O-ring is often the cause of a leaky spout or base. These components are relatively inexpensive and can be replaced with just a few steps. Start by turning off the water supply to avoid flooding your workspace. Then, disassemble the tap by removing the handle and the valve to access the washer or O-ring. Replace the faulty part, reassemble the tap, and turn the water supply back on to check if the leak has stopped.
Tightening Loose Components
In some cases, all your mixer tap needs is a quick tightening of its internal components. Loose valves or cartridges can cause leaks around the handles or base of the tap. Simply use a wrench or screwdriver to tighten these parts, ensuring a secure fit. This can stop leaks immediately without the need for replacement parts.
Preventive Maintenance to Avoid Future Leaks
While fixing a leaking mixer tap is essential, preventing future leaks can save time and money in the long run. Regular maintenance ensures that your tap stays in good working order and reduces the risk of recurring leaks.
Simple tasks such as cleaning your tap regularly to remove limescale, ensuring that the washers and O-rings are in good condition, and checking for signs of corrosion or wear can help you catch potential problems early. Using water softeners if you live in a hard water area can also prevent the buildup of minerals that cause parts to deteriorate faster.
When to Call a Professional Plumber for a Leaking Mixer Tap
While many mixer tap leaks can be fixed with simple DIY methods, there are instances where calling a professional plumber is the best course of action. If you’ve attempted to fix the leak but it persists, or if you’re dealing with more complicated issues like a faulty valve or cartridge, it’s time to seek expert help.
A professional plumber can diagnose the issue accurately, especially if the leak is hidden or stems from a more significant plumbing problem. Additionally, if the leak is causing water damage to other parts of your kitchen or bathroom, immediate professional intervention is necessary to prevent further damage.
How to Choose Quality Replacement Parts for Your Mixer Tap
Choosing the right replacement parts for your mixer tap is crucial to ensure a long-lasting repair. Low-quality parts may seem like a cost-saving option, but they are likely to wear out quickly, leading to further leaks and more repairs. When selecting replacement parts like washers, O-rings, or cartridges, always opt for high-quality, durable components that match the specifications of your tap.
You can find these parts at local hardware stores, or you can contact the manufacturer of your tap to get the right ones. It’s also a good idea to consult a plumber or a knowledgeable store assistant to ensure you’re buying the right parts.
