Water leaks can waste hundreds of litres of water, drive up your bills, and cause serious damage to your home if left untreated. At Champion Plumbing & Drains, our licensed plumbers provide professional leak detection and repair services across Sydney’s Inner West.

We locate the source of leaks accurately and carry out targeted repairs to stop the problem at its cause, not just the visible symptoms. All work is completed with upfront pricing and a lifetime labour guarantee.

Common Signs You Have a Water Leak

Some leaks are obvious, while others remain hidden behind walls, under floors, or underground. You may have a water leak if you notice:

Water bills increasing without explanation

Damp patches on walls, ceilings, or floors

Mould growth or musty smells

Water pooling around your home or garden

Sounds of running water when taps are off

Wet patches under sinks or around toilets

Catching leaks early helps minimise damage and reduces repair costs.

Our Leak Detection Services

We handle all types of residential water leaks, from minor drips to major pipe failures. For specific leak issues, you can find more details below.

Leak Detection

Not all leaks are visible. Our leak detection specialists use professional equipment to locate leaks behind walls, under concrete, and in underground pipes without unnecessary digging.

Burst Pipes & Major Leaks

Burst pipes and major leaks can flood your home quickly and require urgent attention. Our plumbers respond fast to isolate the water supply and repair or replace damaged pipework.

Tap and Fixture Leaks

Dripping taps, leaking toilets, and faulty valves waste water and often worsen over time. We repair worn washers, seals, cartridges, and internal components to stop leaks completely.

Ceiling and Wall Leaks

Water coming through ceilings or walls often indicates a hidden plumbing failure. We trace the leak back to its source and carry out the necessary repairs to prevent further damage.

Hot Water System Leaks

Leaking hot water systems can waste energy and water. At Champion Plumbing & Drains, we repair faulty valves, pipe connections, and tanks across electric, gas, and solar systems.

Why Water Leaks Get Worse Over Time

Even small leaks can cause significant damage if ignored. Ongoing moisture leads to mould growth, timber rot, damage to ceilings and walls, and increased risk of termites in damp areas.

While the leak worsens, your water usage continues to climb. Fixing leaks early helps prevent structural damage and avoids higher repair costs later.

FREQUENTLY ASKED
QUESTIONS

What causes water leaks in homes?

Water leaks are commonly caused by ageing pipes, worn seals and fittings, corrosion, high water pressure, tree root intrusion, or poor installation. In older homes, pipe deterioration is a frequent issue, while newer properties may experience leaks from faulty connections or fixtures.

Are water leaks always obvious?

No. Many leaks occur behind walls, under floors, or underground and may not be visible straight away. Hidden leaks often show up indirectly through rising water bills, damp patches, mould growth, or the sound of running water when taps are turned off.

Is a small leak something to worry about?

Yes. Even small leaks can cause long-term damage if left untreated. Ongoing moisture can lead to mould growth, timber rot, damaged plaster, and higher water bills. Addressing leaks early usually prevents more costly repairs later.

How do plumbers find the source of a leak?

Plumbers start by assessing the symptoms and isolating affected areas. Depending on the situation, this may involve visual checks, pressure testing, or specialised leak detection equipment to pinpoint the source before repairs are carried out.

Can a water leak affect my water bill?

Yes. Hidden leaks can waste hundreds of litres of water per day. Many customers only realise there’s a problem after noticing unexplained increases in their water bill. Once the leak is repaired, water usage typically returns to normal.

Do leaks always require urgent repair?

Some leaks need immediate attention, such as burst pipes or active ceiling leaks, while others can be addressed promptly before damage worsens. If you’re unsure, it’s best to have a plumber assess the issue to avoid escalation.

What should I do if I think I have a water leak?

If you suspect a leak, don’t ignore it. You can check your water meter for unexplained usage and look for visible signs of moisture or damage. A licensed plumber can then locate the source and recommend the appropriate repair.

Do you handle all types of water leaks?

Yes. We handle a wide range of residential water leaks, including taps, toilets, pipes, ceilings, hot water systems, and hidden leaks within walls or underground.
