A leaking tap is one of those small household issues that can be very annoying. At first, it’s just a tiny drip you ignore. Then it becomes a constant sound in the background, and before you know it, you’re wasting water and dealing with a higher bill for no good reason.
I’ve dealt with this more times than I can count, both in my own home and helping friends fix theirs. The good news is that most leaky taps are not complicated problems. In fact, with a bit of patience and a simple method, you can usually fix them yourself without calling a plumber.
What worked for me over the years is understanding the basic structure of a tap and breaking the repair into small, manageable steps. Once you do that, the whole process becomes surprisingly straightforward. In this guide, I’ll walk you through exactly how to fix a leaky tap in a practical, easy-to-follow way.
Why Taps Start Leaking in the First Place
Before jumping into repairs, it helps to understand why taps start leaking. In most cases, the issue is not sudden—it builds up over time.
One of the most common reasons is a worn-out washer. Inside most taps, there’s a small rubber washer that controls water flow. Every time you turn the tap on and off, that washer takes pressure. Over time, it wears down and stops sealing properly.
Another reason for the issue is a loose or damaged valve seat. This is the part where the washer presses against the surface to stop the water flow. If it becomes rough or corroded, water starts slipping through.
Sometimes, the issue is simply a loose fit. Constant use can slightly loosen internal parts, leading to slow drips.
Understanding the problem makes the repair much easier because you’re not guessing—you know what you’re actually looking for.
Tools You’ll Need Before Starting
One thing I’ve learned from doing small home repairs is that preparation makes everything smoother. You don’t need anything fancy for this job.
Here’s what usually helps:
- Adjustable wrench or spanner
- Screwdriver (flat or Phillips depending on your tap)
- Replacement washer (if needed)
- A cloth or towel
- A small bowl to keep screws and parts safe
Having everything ready before you start saves time and avoids frustration halfway through the repair.
Also, make sure you turn off the water supply before doing anything. This is an important step that many people forget in a rush.
Step 1: Turning Off the Water Supply
This might sound obvious, but it’s the most important step. Always turn off the main water supply or the valve under the sink before touching the tap.
Once the water is off, open the tap to release any remaining pressure. This prevents sudden water flow while you’re working.
I’ve skipped this step once in the past, and trust me—it’s not something you want to repeat. A small mistake can quickly turn into a messy situation.
Take your time here. Make sure the water is completely stopped before moving forward.
Step 2: Removing the Tap Handle
Now that the water is off, the next step is to remove the tap handle.
Most handles have a small screw hidden under a cap. You can gently pry the cap open using a screwdriver or even a small knife. Once exposed, unscrew it and carefully lift the handle off.
Some handles might feel stuck due to mineral buildup. If that happens, gently wiggle it instead of forcing it.
At this stage, keep all small parts in a bowl so nothing gets lost. It may seem minor, but missing screws can slow you down later.
Step 3: Opening the Tap Assembly
Once the handle is removed, you’ll see the internal mechanism. This is where the real problem usually sits.
Use a wrench to loosen the packing nut. Turn it slowly and carefully—don’t rush this part. Once it’s loose, you can lift out the spindle or valve stem.
This is the core part that controls water flow. Inspect it closely. Often, you’ll already see signs of wear, especially around the rubber washer at the bottom.
If your tap is older, you might also notice some limescale buildup. That’s normal and can usually be cleaned easily.
Step 4: Checking and Replacing the Washer
This step is usually the main fix.
At the bottom of the spindle, you’ll discover a small rubber washer held in place by a screw. Remove it carefully and assess its condition.
If it looks cracked, flattened, or uneven, it needs replacement. Even slight damage can cause continuous dripping.
Replace it with a new washer of the same size. Make sure it fits properly and sits flat. If the size is slightly off, it won’t seal correctly.
This is the step where most leaky taps are actually fixed. In my experience, replacing the washer alone solves the issue in many cases.

Step 5: Cleaning the Valve Seat
If the tap still leaks after replacing the washer, the issue might be the valve seat.
This is the part inside the tap where the washer presses to stop water. Over time, it can become rough or corroded.
You can clean it using a small brush or even a bit of vinegar to remove buildup. If it feels uneven, you can gently smooth it using a seat wrench or fine abrasive tool.
I’ve found that even a quick cleaning makes a noticeable difference, especially in older taps where mineral deposits are common.
Step 6: Reassembling the Tap
Once everything is cleaned or replaced, it’s time to put the tap back together.
Start by placing the spindle back into position. Tighten the packing nut carefully, but don’t overtighten it. Then reattach the handle and secure it with the screw.
Make sure everything feels snug but not forced. Over-tightening can damage threads or make the handle stiff.
This step is simple but important. A properly reassembled tap should feel smooth when turned.
Step 7: Turning the Water Back On and Testing
Now we reach the critical moment.
Slowly turn the water supply back on and check for leaks. Open the tap and let the water run for a few seconds.
Watch closely around the base and spout. If everything was done correctly, the dripping should be gone.
If you still notice a small leak, don’t panic. It usually means either the washer isn’t seated properly or the valve seat still needs a bit more cleaning.
In most cases, a second quick adjustment solves it completely.
Common Mistakes and How to Avoid Them
When I first started repairing faucets, I made several mistakes that are best avoided.
A common mistake is using a washer of the wrong size. Even a slight discrepancy can cause a leak.
Another error is overtightening parts during assembly. Such actions can damage the threads or make future repairs more difficult.
Some people also forget to clean the valve seat, assuming that a new washer will solve the problem. While this method sometimes works, dirt can still accumulate inside the faucet.
Finally, in the rush to get things done quickly, we often overlook details. A patient and careful approach to repairs makes a big difference.
Simple Maintenance Tips to Prevent Leaks
Even after you have fixed a leak, a few simple maintenance tips can help prevent it from happening again.
Check your faucet regularly for early signs of dripping. Small problems are easier to fix when they first arise.
Do not force the handle when turning the faucet on or off. Gentle operation reduces wear and tear on the internal components.
If your water has a high mineral content, you may need to clean your faucet more frequently to prevent limescale buildup. These small habits can significantly extend the lifespan of your faucet.
When Should You Call for Professional Help?
You can repair most leaking faucets yourself, but sometimes it is better to call a plumber.
If the faucet body is severely corroded or damaged, you may want to replace it instead of repairing it. If multiple parts wear out, a professional can save you time and effort.
In most cases, however, simply replacing the rubber washer and giving the faucet a quick clean is sufficient.
Conclusion
Repairing a dripping faucet might seem daunting, but it is actually basic once you know how to do it. Usually, the problem lies with a worn-out rubber washer or limescale buildup inside the faucet.
The best approach is to proceed gradually and avoid rushing. After your first successful repair, you will feel much more confident tackling similar repairs in the future.
It may be a minor repair, but the results are significant. No more dripping, no more wasted water, and no more stress.
