Fixing a tap involves identifying the cause of the leak, such as a worn washer, faulty O-ring, or loose cartridge. Start by turning off the water supply, then dismantle the tap carefully. Replace the damaged part, reassemble, and tighten all fittings. Using proper tools and quality spare parts ensures the repair lasts. Regular checks and timely maintenance help prevent dripping taps and save water.
What Are the Most Common Reasons a Water Tap Is Leaking?
A water tap is leaking, usually due to internal parts wearing out over time. Identifying the specific cause is the first step towards an effective dripping tap repair.
1. Worn-Out Washer
The washer is a small rubber or silicone disc that presses against the valve seat. Constant friction from turning the tap on and off causes it to wear out, leading to a tap dripping water. This is one of the most frequent reasons for leaks.

2. Damaged Valve Seat
The valve seat connects the tap to the spout. Over time, sediments from water can build up here, causing corrosion and wear. A damaged valve seat results in a leakage tap water issue, typically from the spout area of the faucet.
3. Faulty O-Ring
An O-ring is a small rubber ring that helps create a watertight seal at the base of the tap's spout. If this ring becomes loose or wears out, you will often notice your water tap is leaking around the handle or base every time you turn it on.
4. Incorrect Washer Size or Installation
If a washer was recently replaced but the tap dripping, the new washer might be the wrong size or improperly installed. An ill-fitting washer cannot create a proper seal, leading to persistent drips and the need to fix a leaking tap again.
5. High Water Pressure
Excessively high water pressure can put a strain on the entire plumbing system, including your taps. This constant force can cause components to fail prematurely, resulting in leaks. While not a fault of the tap itself, it is a common underlying cause.
What Tools Do You Need to Fix a Leaking Tap?
Before you begin to repair water tap issues, gathering the right tools will make the process much smoother. Having these basic items on hand is essential for a successful fix.
- An adjustable spanner or wrench
- A set of screwdrivers (both flat-head and Phillips-head)
- Replacement washers and O-rings specific to your tap model
- A clean cloth or rag
- A small bucket or bowl to catch excess water
- Plumber's tape (also known as PTFE tape)
- A pair of pliers
How Can You Fix a Leaking Tap Step by Step?
Following a structured approach is the best way to fix dripping tap problems without causing further damage. This step-by-step guide will walk you through the entire process.
- Step 1: Shut off the valve for the specific tap, which is usually under the sink. If you cannot find it, you will need to turn off the main water supply to your home.
- Step 2: Most taps have a decorative cap on the handle. Carefully pry this off with a flat-head screwdriver to reveal a screw. Unscrew it and gently pull the handle off the tap body. Some handles may require a bit of wiggling to come loose.
- Step 3: After removing the handle, you will see the packing nut or bonnet. Use your adjustable spanner to loosen and remove this nut. This will expose the valve stem, which is the part you need to access to find the washer.
- Step 4: Carefully lift the valve stem out. At the base of the stem, you will find the washer, which is typically secured in place by a small screw. Remove the old washer. You will also see one or more O-rings on the stem. Check them for any signs of wear or damage. Replace the old washer and any worn O-rings with new ones of the same size.
- Step 5: Before reassembling, use a clean cloth to wipe away any mineral deposits or debris from the valve seat (inside the tap body) and all the components you have removed. This ensures a clean and secure fit for the new parts.
- Step 6: Carefully place the valve stem back into the tap body. Tighten the packing nut. Place the handle back on top and secure it with the screw. Finally, put the decorative cap back on.
- Step 7: Slowly turn the water supply back on from the shut-off valve. Check the tap for any drips or leaks. If the dripping has stopped, you have completed the repair of the leaking tap.
How Do You Repair Specific Tap Problems?
Different types of leaks require slightly different approaches. Here is how to address some common issues you may encounter when repairing taps.
- Drip from the Spout: This is almost always caused by a worn-out washer at the base of the valve stem.
- Leak at the Base of the Handle: A faulty O-ring on the valve stem is the most likely culprit for this issue.
- Leak from Under the Spout (Mixer Taps): Worn-out O-rings located at the base of the spout assembly are usually to blame.
- Inconsistent Water Flow: Mineral buildup inside the tap body or the aerator can cause this; cleaning is the solution.
- Stiff or Squeaky Handle: This often indicates a lack of lubrication on the O-rings or a buildup of sediment.
When Should You Call a Professional Plumber for a Leaking Tap?
While many tap repairs are simple, some situations are best left to a professional. Knowing when to call for help can prevent a minor problem from escalating into a major one.
- If you have tried replacing the washer and O-rings, but the tap still leaks.
- If you cannot turn off the water supply, or the shut-off valve itself is leaking.
- If the tap is old and corroded, and you are worried about breaking parts.
- If you suspect the problem is related to high water pressure throughout your home.
- If the leak is coming from within the wall or is not from the tap itself.
- If you are simply not comfortable repairing yourself.
How Can You Prevent Future Tap Leaks?
A few simple maintenance habits can help extend the life of your taps and prevent future leaks.
- Turn taps on and off gently; avoid excessive force.
- Regularly clean the aerator at the tip of the spout to prevent mineral buildup.
- Address small drips immediately before they worsen and cause more damage.
- Consider installing a water softener if you live in a hard water area.
- Have your home's water pressure checked periodically by a professional.
