Pre-Purchase Plumbing Inspections

A pre-purchase plumbing inspection helps you understand the condition of a property’s water systems before you commit. ALD checks the main supply line, water pressure, hidden leaks, hot water system, drainage, sewerage, taps, and fittings. If we find an issue, you can factor repair costs into your decision. If we do not, you can move forward with greater confidence.

A specialist plumbing inspection goes deeper than a general building report.

What Is Pre-Purchase Plumbing Inspections?

A pre-purchase plumbing inspection is a comprehensive assessment of all water supply, hot water, and drainage systems at a property by a qualified specialist. The inspection covers the mains supply line, pressure and flow, internal pipe work, hot water system, waste and drainage systems, sewerage connection, outdoor taps and services, and any obvious or potential leak points or system failures.

A plumbing inspection is different from a general building inspection, which is mandatory in many states but often addresses plumbing superficially. A specialist plumbing inspection identifies problems that block the view: leaks in hidden pipes, corrosion in the supply line, drainage defects, and future risks.

FAQs

  • What does a pre-purchase plumbing inspection cost?

    Inspections start from $495 depending on the property size and complexity. Larger properties or complex systems may cost more. We'll give you a fixed quote during the booking call.

  • How long does a pre-purchase inspection take?

    For a standard residential property, 2–3 hours. Larger properties or properties with complex systems (multiple bathrooms, pool, complex drainage) may take longer. We'll estimate the time during booking.

  • Can we do the inspection quickly so we can make an offer?

    Yes. We understand timeline pressure. We can schedule inspections at short notice and provide findings the same day in urgent situations. Let us know your timeline during booking and we'll work around your needs.

  • Will you identify problems a plumber wouldn't notice?

    Absolutely. A general plumber's perspective is on 'what needs fixing now'. We're looking for latent problems, future risks, and hidden defects that haven't yet failed but will cost money later. We use detection equipment and systematic methods that typical inspectors don't employ.

  • What if you find a major problem? What does it cost to fix?

    Repair costs vary wildly by problem type. A failed hot water system might be $3k–$8k to replace. A corrosion issue in the main line might be $5k–$20k depending on severity and solution. We'll provide estimates based on our findings, but you'll want quotes from licensed plumbers for the actual repair work.

  • Water Leak Detection

    High water bill? Mysterious damp spot? Slow drip inside the walls? We use acoustic listening and tracer gas technology to locate water leaks precisely, without breaking concrete, tiles, or drywall. Full written report included, with repair guidance for your plumber.

  • Pressure Testing

    Inert gas (nitrogen/helium) pressure testing for pipe integrity checks. We test newly installed systems, repaired lines, or existing infrastructure to confirm system integrity. Complies with AS3500 standards and provides documentary proof for councils and builders.

  • Thermal Imaging

    Infrared cameras reveal hidden moisture, heat loss, and structural issues invisible to the eye. We use this technology alongside acoustic and tracer gas methods to build a complete picture of what's happening in your property.
