If you want to know how to fix a leaking tap, start by turning off the water supply, identifying whether you have a traditional tap or mixer tap, then inspecting the washer, O-ring, cartridge or valve components for wear. Some minor tap repairs can be completed at home, while damaged plumbing, concealed fittings or complex mixer problems should be handled by a licensed plumber.
Leaking taps are common in homes across Southern River and surrounding Perth suburbs, including Canning Vale and Harrisdale. Whether the drip is coming from a kitchen mixer, bathroom basin tap or shower fitting, finding the source early can help prevent unnecessary water waste and further wear.
Why Is My Tap Leaking?
Most leaking taps develop because an internal component no longer creates a proper seal. Every time you turn a tap on and off, washers, cartridges and seals experience normal wear.
Common causes include:
- A worn or damaged tap washer
- A deteriorated O-ring
- A faulty ceramic mixer cartridge
- A damaged or worn valve seat
- Loose internal components
- Mineral or debris build-up inside the tap
- Corrosion around older fittings
- Excessive wear within the tap body
Homes in Huntingdale, Gosnells and Thornlie may have a mix of older-style tapware and newer mixer taps, so the cause of a leak can vary considerably from one property to another.
The location of the water can also provide a useful clue. Water dripping from the spout often points to an internal sealing problem, while water appearing around the handle or base may indicate an O-ring, cartridge or connection issue.
How to Fix a Leaking Tap Safely
Before dismantling anything, identify the type of tap you have. Traditional two-handle taps generally operate differently from single-lever mixer taps.
For a basic tap repair:
- Turn off the water supply. Locate the isolation valve for the fixture if available. Otherwise, you may need to isolate the property’s main water supply.
- Open the tap. This helps release remaining water and pressure from the line.
- Protect the basin or sink. Cover the waste opening so small screws and components cannot fall into the drain.
- Remove the tap handle or cover. The exact method varies between tap designs.
- Inspect the internal components. Look for worn washers, damaged O-rings, loose parts or a deteriorated cartridge.
- Replace the correct component if appropriate. Match replacement parts carefully to the existing tap.
- Reassemble the tap. Avoid overtightening components.
- Restore the water gradually. Check the tap and surrounding fittings for leaks.
If you are in Piara Waters or Forrestdale and your tap uses unfamiliar internal components, avoid forcing parts apart. Modern mixers can vary by brand and model, and using the wrong replacement component can damage the fitting.
Traditional Taps: Check the Washer and O-Ring
Older-style taps commonly use a rubber washer that presses against a valve seat when you turn the tap off. Over time, the washer can flatten, crack or become hard.
A worn washer is one of the first things worth checking when a traditional tap continues dripping from the spout. This type of repair may be relevant in established homes throughout areas such as Seville Grove and Camillo, where older tapware may still be in use.
O-rings provide seals around moving sections of the tap. If water leaks around the spindle or handle rather than directly from the outlet, an O-ring may be worn.
Make sure any replacement washer or seal matches the original size and type. Installing an incorrect component can leave the leak unchanged or make the tap difficult to operate.
What About a Leaking Mixer Tap?
Mixer taps are common in kitchens, bathrooms and laundries throughout Southern River and nearby suburbs such as Armadale and Kelmscott. Instead of using separate traditional hot and cold tap mechanisms, many single-lever mixers rely on an internal cartridge.
If your mixer continues dripping after you shut it off, the cartridge may be worn or damaged. You might also notice:
- Water leaking around the mixer handle
- Difficulty controlling temperature
- A stiff or loose lever
- Reduced water flow
- Water appearing around the base of the mixer
Learning how to fix a leaking tap becomes slightly more complicated with mixer taps because cartridges vary between manufacturers and models.
Some cartridges can be replaced, but identifying the correct part matters. Forcing an incorrect cartridge into the mixer can damage the tap body and turn a relatively simple repair into a full tap replacement.
Why Does My Tap Still Leak After Changing the Washer?
Changing a washer does not solve every dripping tap.
If a traditional tap continues leaking after a new washer has been installed, the valve seat may be damaged, worn or covered with deposits. The spindle or another internal component may also have deteriorated.
This is a common point where homeowners in Maddington, Martin and Langford may find that repeated DIY repairs stop being cost-effective. If the same tap continues leaking despite a new washer, the issue may sit deeper within the fitting.
Repeatedly tightening the tap harder is not a good solution. Excessive force can damage washers, seats and internal components and may make the problem worse.
Can You Fix a Leaking Shower Tap?
The same general principles apply to many shower taps, but shower plumbing can involve different mixers, cartridges and concealed components.
A dripping shower head does not always mean the shower head itself is faulty. If water keeps coming through the shower after the taps or mixer have been completely turned off, the problem may sit within the tap mechanism.
In homes around Cannington and Ferndale, leaking shower mixers can sometimes involve cartridges or fittings located behind the wall. If the mixer is concealed or you cannot clearly identify the cause, professional assessment can reduce the risk of damaging tiles, waterproofing or surrounding fittings.
What About Kitchen Mixer Taps?
Kitchen mixer taps are used frequently throughout the day, so internal cartridges, seals and flexible connections can eventually wear out.
If you notice water around the base of the mixer, check whether the leak occurs only while the tap is running or continues when the tap is switched off. Water appearing underneath the sink can point to a loose connection or flexible hose rather than the mixer cartridge itself.
Homes in Leeming and Riverton often have modern kitchen mixers, and replacement parts can vary significantly between brands. Matching the correct cartridge or seal is important before attempting a repair.
Should You Repair or Replace the Tap?
A simple washer or seal replacement can make sense when the rest of the tap remains in good condition.
Replacement may be more practical when:
- The tap body is badly corroded
- Replacement cartridges are unavailable
- Several internal parts are worn
- The tap repeatedly develops leaks
- The mixer is difficult to operate
- The tap is physically damaged
For older tapware, repeatedly replacing individual components can eventually cost more than installing suitable replacement tapware.
If you are renovating a bathroom, kitchen or laundry in Southern River or elsewhere in Perth, replacing an ageing tap at the same time can also reduce the chance of dealing with recurring leaks shortly after the renovation is finished.
Can a Leaking Tap Increase Water Use?
Yes. Even a slow drip continues using water every hour of the day.
The amount depends on how quickly the tap is leaking, but a persistent drip should not be ignored simply because the flow appears small. A leak can also become worse as internal seals continue to deteriorate.
Fixing the problem early can help reduce unnecessary water use and prevent moisture from affecting cabinetry, benchtops or surrounding surfaces.
When to Call a Professional
Knowing how to fix a leaking tap is useful, but not every leak should become a DIY project.
Call a licensed plumber if water continues leaking after a basic repair, the isolation valve does not work, the tap body is damaged, pipework is leaking or the mixer is concealed. You should also arrange professional help if you cannot confidently identify the component causing the problem.

Conclusion
Understanding how to fix a leaking tap starts with identifying your tap type and determining where the water is escaping. Traditional taps may need a washer or O-ring, while modern mixer taps often rely on replaceable cartridges.
Basic tap maintenance can sometimes solve a minor drip, but persistent leaks, damaged fittings and concealed plumbing should not be ignored.

Frequently Asked Questions
What is the most common cause of a leaking tap?
A worn washer is a common cause in traditional taps. Mixer taps often develop leaks when their internal cartridge or seals become worn.
Why is my mixer tap dripping when it is turned off?
A worn cartridge, damaged seal or internal debris may prevent the mixer from closing completely. Replacing the correct cartridge can often resolve the problem.
Why does my shower keep dripping after I turn it off?
The problem may come from a worn washer, cartridge or internal mixer component rather than the shower head itself. If the leak continues consistently, the tap or mixer should be inspected.
Is it better to repair or replace a leaking tap?
Repair usually makes sense when the tap is in good condition and only a washer, seal or cartridge has failed. Replacement may be more practical if the tap is corroded, repeatedly leaking or has obsolete internal parts.
