Pinpointing Hidden Water Leaks Before Anything Opens

Is your meter ticking with taps off? Sydney Water's check needs every tap and water appliance off for at least an hour, and movement means a concealed leak. Our licensed team traces the pipe.

Hidden Water Leak Detection Services

Hidden water leak detection starts from where the water shows, and we match the leak locating method to that spot:

  • Plumber checking a gas meter regulator beside a brick wall

    Underground Leak Detection

    Sydney Water says a green lawn patch, unlike the surrounding grass, can mean a buried pipe leak. Our underground leak detection traces that service pipe between the meter and house.

  • New copper water pipes fixed to a block wall

    Wall Leak Detection

    When paint bubbles on a wall, a service pipe can be leaking inside the cavity behind it. We pinpoint that leak with wall leak detection before anyone opens the plaster.

    Slab Leak Detection

    We trace a slab leak along a water line buried in the concrete. Our slab leak detection finds the leak before anyone cuts concrete, so one small section comes up.

    Ceiling Leak Detection

    Tracing a ceiling stain starts at the bathroom or pipe run directly above it. With ceiling leak detection, we follow that stain back to the leaking service pipe or fitting.

    Hot and Cold Lines

    Pipe leak detection covers the cold water line and heated line. A separate test on each line shows whether the leak sits on the hot line or the cold one.

    Leak Reports for Claims

    If you claim Sydney Water's hidden leak allowance, the application asks for details including the plumber's business name, licence number and invoice. We hand those details over with the repair.

What Causes a Hidden Water Leak

A hidden water leak commonly starts with high water pressure, a leaking tap at the meter or corroded flexi hoses:

  • High Water Pressure

    Sydney Water's network averages 52 metres head (the height pressure lifts water), and some customers top 100 metres head. High pressure can break pipes, says the Water Pressure Management Program.

  • Leaking Meter Taps

    When the meter tap (the tap beside your meter) leaks, the owner is responsible. Sydney Water still fixes it free within 10 working days, or within 3 hours for a fee.

  • Corroded Flexi Hoses

    Flexi hoses caused one in ten of the home insurance claims Suncorp processed in 2025. Standards Australia says the 2025 AS/NZS 3500.1, the water services standard, adds hose rules.

  • Low-Lying Streets

    Sitting low in a supply zone raises pressure, because the reservoir sits higher above the property. Sydney Water cuts pipe breaks using pressure reduction valves, which lower water main pressure.

How Much Water Leak Detection Costs

Water leak detection costs $450 for the first hour on Sydney Water's 2026 WaterFix Concealed Leaks list:

  • First hour: Sydney Water's 2026 list charges $450 for the first hour and $130 per extra half-hour. Sydney Water quotes repairs separately.
  • Obvious or no leak: Sydney Water sets a $260 minimum on its 2026 list when the leak is obvious or there's none. A meter check shows whether a search is needed.
  • Our pricing: We Find It Leak Detection keeps a $0 call-out fee and fair, upfront pricing, no surprises. Search time and line count drive the final cost.

Why Early Detection Saves Money

Sydney Water's hidden leak allowance covers only half of one quarter's usage charge, leaving the rest on your bill:

  • Allowance Covers Half

    Sydney Water's allowance takes "50% of the water usage charge" off the worst-hit quarter. Each property can claim it once every 5 years, within a year of the leak repair.

  • Detection Before Demolition

    If the leak shows or the linings are coming out, cutting in makes sense. Otherwise, non-invasive leak detection marks the spot, instead of cutting into walls and floors to search.

  • Energy Lost on Hot Lines

    Losing water from a hot line wastes heating energy too, according to Sydney Water. We locate and fix that line, so you stop paying to heat water you never use.

Our Process

Our plumber works in five steps, from the water meter test to isolating, tracing, marking, then repair and retest:

  1. Meter Test First

    Our plumber reads the water meter with every tap and water appliance shut, confirming any escaping water and its rate. You see that proof before you pay for a search.

  2. Isolate Each Section

    When the dial keeps moving, we isolate and test garden taps, the house supply and each hot or cold line separately. Each step narrows the search to one pipe run.

  3. Listen and Trace

    Tracing starts with pipe location, then acoustic listening, using a microphone that picks up water leaving a pressurised pipe. A safe tracer gas helps us detect and locate the leak.

  4. Mark the Leak

    We mark and report the exact leak spot, then set out the fix in a written quote. Best Price Guaranteed covers that written quote before any repair work starts.

  5. Repair and Retest

    Once the spot is marked, leaking pipe repairs go through one small opening. A second meter test then shows the line holding, with the dial still and every tap off.

Common Water Leak Problems We Fix

Four common signs point to a concealed leak on the water service, and each is fixable once found:

  • Meter Turning With Taps Off

    If the meter dial keeps ticking with all taps off, water is leaking somewhere on the property. We locate that leak, so the fix touches one spot, not a room.

  • Damp Patch Near the Skirting

    Damp patches inside the house can mean a leak, Sydney Water says. Near the skirting, we test for a water service leak behind the lining before anything is pulled off.

  • Green Patch in Dry Weather

    We look for a lawn patch that stays green in dry weather, which Sydney Water links to a leaking buried pipe. From there, we follow the pipe to the leak.

  • Bill Up With Steady Use

    When the water bill climbs while use holds steady, Sydney Water treats that as a leak sign. A meter check comes first, then we trace where the extra water goes.

Frequently Asked Questions

How Can I Check for a Water Leak in Sydney?

You can check for a water leak in three steps: shut every tap and water appliance, read the meter, then wait at least an hour. Sydney Water says any dial movement means a leak.

Do Water Leak Detectors Really Work?

Yes, a plug-in water leak detector works by sounding an alarm when water reaches its sensor, so it suits spots like under a sink. The alarm can't find a pipe leaking inside a cavity.

Who Pays for a Water Leak on My Property?

The property owner pays for a leak under the house, as pipes on the property are theirs. Sydney Water often fixes the stretch from its water main up to one metre inside the boundary, free.

Can Water Leak Detection Avoid Breaking Tiles?

Yes, concealed leak detection can find a leak without breaking tiles to search, because acoustic listening and tracer gas narrow it down first. Only the one marked spot then gets opened for the fix.

How Long Does Water Leak Detection Take?

Detection time comes down to how many water lines cross the property and how hard each one is to isolate. Your own meter check takes at least an hour with every tap off.

How Do I Book Water Leak Detection?

Booking water leak detection in Sydney takes one call to (02) 9073 7896, with your meter reading and water bill on hand. We Find It Leak Detection books Same Day Service for a $0 call-out fee.
