A dripping tap is usually caused by worn washers, damaged O-rings, or high water pressure, leading to constant leaks and wasted water. If you’re wondering why is my tap dripping, it’s often due to internal wear inside the tap mechanism that needs simple repair or part replacement.
In many Australian homes, especially older properties, even a slow drip can waste thousands of litres annually. Understanding the cause early helps you avoid higher water bills and potential fixture damage.
Why is my tap dripping: Common causes explained
When your tap starts dripping, it’s rarely random. Most issues come from everyday wear and tear or ageing plumbing components.
Here are the most common causes:
- Worn rubber washer inside the tap
- Damaged O-ring or spindle
- Corroded valve seat
- Loose or faulty tap assembly
- Excess water pressure in your plumbing system
Hard water conditions in parts of Australia can also speed up internal wear, making leaks more likely over time.
How to fix a dripping tap safely at home
If you’re comfortable with basic tools, you may be able to stop a minor drip yourself. Always turn off the water supply before starting any repair.
Basic steps include:
- Turn off the mains water supply
- Remove the tap handle carefully
- Inspect washer and O-ring for damage
- Replace worn parts with matching fittings
- Reassemble and test for leaks
If the drip continues after replacement, the issue may be deeper within the valve or pipe connection. This is where professional help is recommended.
Clearline Plumbing often assists homeowners who have attempted DIY fixes but still face ongoing leaks.
When water pressure is the hidden problem
Sometimes the issue isn’t just worn parts. High water pressure can force water through even a healthy tap seal.
Signs include:
- Multiple taps dripping in the home
- Loud pipe noises when turning taps off
- Sudden leaks after plumbing work
Australian plumbing systems are typically designed to operate within regulated pressure levels, and exceeding them can lead to ongoing fixture damage.
Clearline Plumbing can assess pressure levels and install regulators if needed to protect your system long-term.
