Same-Day Water Leak Repair Across Sydney's Inner West

Champion Plumbing & Drains repairs water leaks across Ashfield, Balmain, Marrickville, Newtown, Leichhardt and the wider Inner West. Our licensed plumbers attend the same day in most cases, diagnose the source of the leak, and complete the repair on the first visit where the parts are on the van. We’re currently running a $0 call-out fee on standard service bookings*, which means our team arrives, assesses the leak and gives you a written quote before any work begins.

Every repair is backed by our lifetime labour guarantee on workmanship. If the source of the leak isn’t visible, we move into leak detection using acoustic equipment and thermal imaging to pinpoint it without unnecessary damage to plaster or floors.

Types of Leaks We Fix

Water leaks come in a few different shapes, and each one has its own diagnostic process and parts to swap out. Our team carries common fittings, seals and valves on the van, so most repairs are wrapped up in a single visit. The most frequent leak types we repair across the Inner West are set out below.

Burst Pipes and Major Leaks: A burst mains line or a failed copper joint releases active water and needs immediate isolation at the mains. Our emergency team responds 24/7 across the Inner West, shuts the water off at the mains, and replaces the failed section with new copper or PEX (cross-linked polyethylene pipe). Mains failures, slab leaks and aged galvanised pipe runs are all covered under our burst pipe repair service.
Tap and Fixture Leaks: Dripping taps, leaking mixers, and faulty stop valves usually come down to a worn washer, cartridge or O-ring (the rubber seal inside the tap body). Our plumbers carry common spare parts for Caroma, Dorf, Methven and Phoenix tapware, so most fixture leaks get repaired on the same visit without ordering parts in.
Ceiling and Wall Leaks: Brown stains, sagging plaster and active drips through ceilings or walls usually point to a leak inside the wall cavity or under a tiled floor above. We trace the source first using moisture meters and acoustic equipment before any plasterboard or tile gets opened up. That way the access point stays as small as the repair allows, and the patch-up afterwards is straightforward.
Hot Water System Leaks: Hot water systems tend to leak from three common points: the pressure relief valve (PRV, a safety valve that releases pressure on the hot water tank), the tank itself when internal corrosion sets in, and the cold water inlet or hot water outlet connections. Our plumbers diagnose the source across electric, gas and solar units, and repair or replace as needed under our hot water plumbing service.
Toilet and Cistern Leaks: A running toilet usually traces back to a worn fill valve, a flush valve seal that no longer seats, or a float that’s out of alignment. Leaks at the base of the toilet pan point to a failed wax seal (the wax ring that sits between the pan and the floor flange) or a cracked floor flange itself. Our team replaces internal valves and reseats the pan on the same visit in most cases.

Why Water Leaks Get Worse Over Time

A small leak that drips behind a wall, into a cavity or under a slab doesn’t stay small. Moisture trapped inside a building cavity feeds mould growth on plaster and framing within 48 to 72 hours, and prolonged dampness leads to rot in the structural timber. Damp cavities also attract termites, which favour the softened, water-affected timber that builds up around long-term leaks.

Beyond the building itself, an unaddressed leak pushes water usage up on every billing cycle. Fixing the source within the first few days of a leak being noticed is consistently cheaper than the combined cost of the repair plus plaster, timber, paint and water bills six months down the track.

Our Repair Process and Lifetime Labour Guarantee

Every booking follows the same four steps.

Our team attends the same day in most cases across the Inner West and assesses the leak on arrival.
We give you a written quote covering the repair scope and parts before any work begins.
The repair is completed by licensed plumbers using parts carried on the van, wherever possible, so we don’t need to come back a second time.
The workmanship is backed by our lifetime labour guarantee, which covers the labour side of the repair for as long as you own the property.

Standard service bookings currently carry a $0 call-out fee*, so the assessment and the written quote come at no cost. If the leak’s hidden, the diagnostic and the repair quote are provided in the same visit, so you can decide on the spot.

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. See our full pricing for our standard leak repair rates.

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, call us today and we’ll assess the situation, $0 call-out fee.
