Why You Must Inspect The Septic Tank Before You Buy A House


Bevan Plumbing • August 13, 2024

Have you ever wondered what might be lurking beneath your potential dream home? While many homebuyers focus on the aesthetics, layout or even the garden of a house, there’s one crucial aspect that often goes overlooked— the septic tank. It’s easy to get caught up in the excitement of buying a new property, but before you sign on the dotted line, it’s essential to consider the condition of the septic system. In this blog, we’ll explore why inspecting the septic tank should be a non-negotiable part of your home-buying process.

Hidden Costs of a Failing Septic System

One of the biggest concerns with a neglected septic system is the potential for expensive repairs. Replacing a septic tank can be costly if you catch the problem before it becomes a full-blown disaster. Even worse, a malfunctioning system can lead to contaminated groundwater, which can affect your drinking water and potentially harm your health.


For prospective homeowners, discovering that the septic system is on its last legs after the purchase can feel like a financial nightmare. That’s why it’s crucial to have it inspected by a qualified septic tank plumber before finalising any sale.

Health & Environmental Risks

A failing septic system is more than just a financial burden—it’s a serious health and environmental hazard. When a septic system fails, untreated sewage can leach into the ground, potentially contaminating nearby water sources, including rivers, lakes and even the local water table. This can lead to outbreaks of waterborne diseases, posing significant risks to your family and the broader community.


Moreover, the environmental impact of a malfunctioning septic system can be devastating. Raw sewage can destroy local ecosystems, harming plants, animals and fish. This affects the environment and reduces the aesthetic and recreational value of nearby natural areas.

Influence Property Value

A thorough septic tank inspection doesn’t just protect you from unexpected costs; it can also directly impact the property’s value. Knowing the state of the septic system gives you the upper hand when assessing the true worth of the home.


  • Increased Value: A well-maintained septic system can increase the property’s value, assuring potential buyers that the system won’t require immediate attention.
  • Avoiding Devaluation: Conversely, a neglected or failing system can decrease the value of the property. Prospective buyers may be turned off by the potential for costly repairs, leading to a lower sale price or extended time on the market.
  • Informed Investment: With an inspection, you’re making an informed investment, ensuring the property’s value aligns with the asking price.

Legal Requirements and Compliance

In Australia, septic systems must meet specific regulations and standards to operate safely and effectively. When purchasing a home, verify that the septic system complies with local laws. 


Non-compliant systems pose health and environmental risks and could result in fines or legal action. Additionally, if the system doesn’t meet the required standards, you may be obligated to upgrade or replace it, which can be costly.


A septic tank inspection can help you confirm that the system adheres to all legal requirements, giving you peace of mind and protecting you from potential legal issues.

Identifying Signs: What An Inspection Reveals About Your Future Home

A comprehensive septic tank inspection can reveal a lot about the overall condition of the home you’re considering. It’s more than just checking the tank; the inspection can uncover issues that might go unnoticed.

Structural Integrity

An inspection will assess the septic tank’s structural integrity, looking for cracks, leaks or other signs of deterioration that could indicate future problems.

Drainage Efficiency

How efficiently the system processes waste is another critical factor. An inspector will evaluate whether the drainage is functioning correctly or if there are signs of blockages or poor soil absorption, which can lead to overflow or backups.
