When to take action

Plumbing problems are more than just inconvenient, they can damage your property, create safety risks, and lead to significant financial loss. If plumbing work on your property is defective, incomplete, or unlawful, you may be entitled to make a claim under the plumber’s insurance or pursue legal action.

Common signs of defective plumbing include:

  • Persistent leaks from roofs, balconies, walls, or ceilings

  • Mould or water stains appearing inside your home

  • Structural movement or slab heave caused by water damage

  • Timber floors cupping or shifting

  • Sewer or stormwater systems repeatedly blocking or back-flowing

  • Malfunctioning heating or cooling systems

  • Stormwater pooling in subfloors or around your property

If you notice these issues, it’s important to seek legal advice early to protect your rights and avoid escalating damage.

Compliance certificates & why they matter

In Victoria, licensed plumbers must issue a compliance certificate for certain types of plumbing work, including:

  • Jobs valued at $750 or more (including labour, materials, or appliances)

  • Work on below-ground sanitary drains

  • Installation, replacement, or relocation of gas appliances or gas piping

  • Installation or modification of cooling towers

Plumbers are legally required to give you a signed certificate within 5 days of completing the work and notify the Victorian Building Authority (VBA). Failure to do so is an offence.

Why this matters: compliance certificates link the plumbing work to the plumber’s insurance. If defects are discovered later, these certificates allow you to access the plumber’s insurer (through a freedom of information process) and make a claim. Without them, recovering compensation becomes more difficult..
