Case Studies

Explore Our Case Studies Library

If you're considering professional leak detection, you want concrete answers, not marketing language. The case studies below show exactly what we've found, how we found it, and what changed for the client. Each one is a real job we've been engaged on, written up with the property owner's permission and any identifying details adjusted where requested.

Types of Cases We Document

  • Residential

    Family homes, rentals, and investment properties — water-bill spikes, slab leaks, and bathroom waterproofing failures.

  • Commercial

    Office towers, retail centres, and warehouses — distributed water loss, hot-water systems, and cooling-tower plumbing.

  • Strata & Body Corporate

    Multi-unit complexes — shared-property leaks, allocated-cost disputes, and dispute-resolution evidence.

  • Pool & Spa

    Pool structure, plumbing, and equipment-area faults — pinpointed and quoted in a single visit.

  • Builders & Developers

    Pre-pour pressure tests, pipe location before groundwork, and pre-handover defect inspections.

What Each Case Study Includes

Every case study follows the same documented structure so you can compare situations across property types and find the closest match to your own.

In Brunswick: Residential Water Leak Detection

Brunswick, VIC · 2025

  1. The Situation

    Residential leak detection case study for a Brunswick, VIC property where the water bill had tripled in a single quarter. No visible leak. Two plumbers had visited and left without a finding.

  2. The Problem

    A slab-buried copper supply line had developed a pinhole leak under the kitchen — invisible from above and below, but acoustically detectable through the polished concrete.

  3. Detection Method

    Acoustic listening over the slab established the loudest reading at the kitchen-island floor; tracer-gas confirmation pinpointed the leak to within 30cm.

  4. Outcome

    Plumber cut a single 25 × 25cm section of slab, replaced the failed elbow fitting, and re-poured. Leak Allowance claim approved by the water authority for 2.5 quarters of high usage.

In North Sydney: Pool & Spa Leak Detection

North Sydney, NSW · 2024

  1. The Situation

    Pool and spa leak detection case study in North Sydney for a renovated 8 × 4m concrete pool losing about 2cm of water a day — well above expected evaporation. Owner had topped up the pool weekly for six months before calling.

  2. The Problem

    A hairline crack in the skimmer-throat had opened up, draining water below the visible water-line whenever the pump cycled.

  3. Detection Method

    Dye injection confirmed the structural breach; pressure testing of the return and suction lines isolated the failure to the skimmer assembly only.

  4. Outcome

    A targeted repair on the skimmer fitting alone resolved the loss. Total repair cost was 5% of the quote the previous specialist had given for a complete plumbing replacement.

In Sydney CBD: Commercial & Strata Leak Detection

Sydney CBD · 2025

  1. The Situation

    Commercial strata leak detection case study in Sydney CBD for a 28-unit complex with a recurring damp stain on the ceiling of unit 8 after every heavy rain event. Body corporate was facing a tribunal-led dispute over cost allocation.

  2. The Problem

    A failed waterproofing membrane on the level-3 balcony of unit 12 was discharging into the wall cavity above unit 8 — a four-storey vertical travel path the as-built drawings did not anticipate.

  3. Detection Method

    Thermal imaging across the suspected wet stack, paired with flood testing on each candidate balcony above unit 8, identified the source unambiguously.

  4. Outcome

    Report became the cost-allocation basis for the body corporate's repair levy. Dispute resolved without tribunal intervention; remedial waterproofing repaired within 6 weeks.
