A leaking tap might seem like a small household issue, but it can quickly turn into a bigger problem if ignored. That constant dripping sound is not just annoying it also wastes a surprising amount of water and can increase your utility bills over time. The good news is that most leaking taps can be fixed at home with basic tools and a little patience.
This guide will walk you through everything you need to know about fixing a leaking tap, including the common causes, tools required, and detailed step-by-step instructions. Whether you are a beginner or someone with basic DIY experience, you’ll be able to follow along easily.
Why Do Taps Start Leaking?
This section explains the basic reasons behind leaking taps so you can correctly identify the problem before attempting repairs. Most tap leaks develop gradually due to wear and tear inside small components that control water flow. Understanding these causes helps you avoid guesswork and fix the exact faulty part efficiently.
1. Worn-out washer
This section explains how a damaged washer leads to leaks. The washer is a small rubber seal that prevents water from passing when the tap is closed, but over time it becomes hard, cracked, or flattened, causing continuous dripping even when the tap is fully turned off.
The washer is a small rubber ring inside the tap that helps create a tight seal when the tap is closed. Over time, it becomes stiff, cracked, or flattened, causing water to leak through.
2. Damaged O-ring
This section describes how a faulty O-ring can cause leakage around the tap handle area. The O-ring is responsible for sealing internal joints, and when it wears out or shifts from its position, water starts seeping from the base of the tap.
The O-ring is another small rubber component that seals the handle area. If it becomes loose or damaged, water may leak from the base of the tap.
3. Loose parts
This section explains how frequent use of the tap can loosen internal components over time. When fittings inside the tap mechanism become loose, they fail to maintain proper pressure, leading to dripping or minor seepage from the spout or handle area.
Constant turning of the tap handle can loosen internal fittings, leading to dripping or seepage.
4. Corroded valve seat
This section explains how mineral buildup and corrosion affect the valve seat. When the surface becomes uneven or damaged, it prevents the washer from forming a proper seal, allowing water to escape even when the tap is fully closed.
The valve seat connects the tap to the spout. If it becomes corroded due to mineral buildup, it can prevent a proper seal.
5. High water pressure
This section explains how excessive water pressure can contribute to tap leaks. When pressure is too strong, it forces water through small gaps inside the tap mechanism, making even minor wear or damage result in noticeable dripping.
In some cases, excessive water pressure can force water through even small gaps inside the tap mechanism.
Understanding the cause helps you fix the issue correctly instead of guessing.
Tools and Materials You Will Need
This section lists the basic tools required to repair a leaking tap safely and effectively. Having all tools prepared in advance helps make the repair process smoother, reduces interruptions, and ensures you can complete each step without delays or missing components.
- Adjustable wrench or spanner
- Screwdriver (flat-head or Phillips depending on tap type)
- Replacement washer set
- Replacement O-rings (if needed)
- Plumber’s tape (Teflon tape)
- Cloth or rag
- Small brush (for cleaning parts)
- Bucket or bowl (to catch dripping water)
Having everything ready beforehand will make the process smoother and faster.
Step-by-Step Guide to Fix a Leaking Tap
This section provides a complete step-by-step method for repairing a leaking compression tap. Following these steps carefully ensures safe disassembly, proper identification of faulty parts, and correct reassembly to restore normal water flow without unnecessary damage or complications.
Step 1: Turn Off the Water Supply
This section explains the importance of stopping water flow before beginning any repair work. Turning off the supply prevents flooding, reduces pressure in the system, and allows you to safely dismantle the tap without water spraying or leaking unexpectedly.
- Locate the main water valve in your home or the valve under the sink.
- Turn it clockwise to stop the water flow.
- Open the tap afterward to release any remaining water pressure.
Skipping this step may lead to flooding or unnecessary mess.
Step 2: Plug the Drain
This section explains a simple precaution to prevent small parts from falling into the sink drain during repair work. Blocking the drain helps you safely handle screws and components without losing them.
- Place a sink plug in the drain, or
- Cover it with a cloth or stopper.
This simple step can save you a lot of frustration later.
Step 3: Remove the Tap Handle
This section explains how to safely remove the tap handle to access internal components. Careful removal ensures you do not damage the handle or surrounding fittings while exposing the internal mechanism for repair.
- Look for a screw on the handle (sometimes hidden under a decorative cap).
- Use a screwdriver to remove the screw.
- Gently pull off the handle.
If it is stuck, wiggle it slowly instead of forcing it.
Step 4: Unscrew the Tap Head (Valve)
This section explains how to remove the tap head or valve assembly after the handle is taken off. This step is necessary to access internal parts like washers and seals that are often responsible for leaks.
- Use an adjustable wrench to loosen it.
- Turn it anti-clockwise to remove it completely.
Be careful not to apply too much force, as it can damage the fittings.
Step 5: Inspect the Washer and O-Ring
This section explains how to carefully examine the internal sealing components inside the tap valve. Proper inspection is important because most tap leaks are caused by worn-out rubber parts that lose their ability to create a tight seal over time, leading to continuous dripping even when the tap is closed.
Inside the valve, you will find the washer at the bottom and possibly an O-ring along the shaft.
Check for:
- Cracks or splits
- Hard or brittle rubber
- Flattened shape
- Dirt or mineral buildup
In most cases, the washer is the main cause of leakage.

Step 6: Replace Damaged Parts
This section explains how to replace faulty internal components such as washers and O-rings. Replacing these small parts restores the tap’s sealing ability and is usually enough to stop leaks without needing to change the entire tap mechanism.
If the washer or O-ring is damaged, replace it with a new one.
- Remove the old washer using a screwdriver if needed.
- Fit a new washer of the same size.
- Replace the O-ring if it looks worn out.
Make sure the new parts fit tightly but not forced.
Step 7: Clean All Components
This section explains the importance of cleaning all tap components before reassembly. Dirt, rust, and mineral deposits can prevent proper sealing, so cleaning ensures smooth operation and helps the new parts function effectively for a longer time.
- Use a small brush to remove dirt and scale buildup.
- Wipe parts with a clean cloth.
- Check the valve seat inside the tap body. If it has mineral deposits, clean it gently.
A clean surface ensures a proper seal and prevents future leaks.
Step 8: Reassemble the Tap
This section explains how to correctly put the tap back together after replacing and cleaning the internal parts. Proper reassembly ensures all components align correctly and function smoothly without causing new leaks or mechanical issues.
- Screw the valve back into place
- Tighten it with a wrench (not too tight)
- Reattach the handle
- Secure the screw and cap
Make sure everything is aligned properly.

Step 9: Turn On the Water Supply
This section explains how to safely restore water flow after completing the repair. Turning the water back on slowly helps you check for leaks under controlled pressure and ensures the tap is functioning properly before full use.
Slowly turn the water supply back on.
- Check for any leaks immediately.
- Turn the tap on and off a few times.
- Observe if the dripping has stopped.
If everything is done correctly, the tap should now be leak-free.
Step 10: Test and Monitor
This section explains the importance of observing the tap after repair to ensure the issue is fully resolved. Some problems may not appear immediately, so monitoring helps confirm whether the repair was successful or if further adjustments are needed.
Even after fixing, keep an eye on the tap for a few hours or a day.
- If dripping continues, the washer may still be misaligned
- If leaking comes from the handle, the O-ring may need adjustment
- If the issue persists, the valve seat might be damaged
Sometimes older taps may require complete replacement if wear is too severe.

1. Don’t overtighten taps
This section explains how excessive force when closing a tap can damage internal rubber components. Over time, overtightening compresses the washer too much, causing it to wear out faster and eventually leading to continuous dripping even when the tap is fully closed.
Many leaks happen because people force the tap shut. This damages the washer faster.
2. Clean taps regularly
This section highlights the importance of removing mineral deposits and dirt buildup from taps. Regular cleaning keeps internal parts functioning smoothly and prevents blockages or rough movement that can contribute to early wear and leakage issues.
Mineral buildup can affect performance. Clean taps occasionally to keep them smooth.
3. Check water pressure
This section explains how high water pressure can stress tap components and cause leaks over time. Installing a pressure regulator helps maintain balanced flow and protects plumbing fixtures from unnecessary strain and damage.
If your home has very high pressure, consider installing a pressure regulator.
4. Replace washers early
This section emphasizes preventive replacement of washers before they completely fail. Timely replacement helps avoid sudden leaks and reduces the risk of damage to other internal tap components.
Don’t wait for severe leaking. Replacing washers every few years can prevent damage.
When to Call a Plumber
This section explains situations where DIY tap repair is no longer effective and professional help is required. Calling a plumber at the right time prevents further damage and ensures deeper plumbing issues are properly diagnosed and fixed.
While most tap leaks are easy to fix, sometimes professional help is needed. Call a plumber if:
- The tap body is cracked or corroded
