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.
Some leaks are obvious, while others remain hidden behind walls, under floors, or underground. You may have a water leak if you notice:
Catching leaks early helps minimise damage and reduces repair costs.
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.
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 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.
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.
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.
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.
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.
If your issue extends beyond leaks, we can help with a full range of plumbing solutions.

We back every job with a Lifetime Labour Guarantee, because doing it right matters.

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.

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.
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.
