Drainage Inspections, a must as part of Building & Pest

When it comes to buying a new home, we all know the importance of conducting a Building & Pest Inspection, but have you considered the state of the property’s drainage system? It’s important to assess the condition and functionality of the current drainage system as this can affect the structural integrity of the home, or leave you with a very hefty drainage rectification bill later down the track.

Potential stormwater and sanitary drainage issues include;

  • Blockages (roots, debris etc)

  • Leaks & pipe damage

  • Pipe deterioration

  • Ineffective pipework (pipework that’s too small for the area to drain efficiently in large downpours)

  • Inadequate fall

  • Septic tank failure (ie. Absorption beds, baffles, tank cracks, roots in system etc)

  • Effluent pit inefficiency

  • Grease trap inefficiency

Drainage rectification and reruns can cost you between $3,000 and $20,000. That’s a cost you need consider when making an offer on a property. So how do you assess the drainage?

For stormwater, the only way to determine the state of your network of underground pipes and drains is to conduct drain camering (CCTV). It involves sending a small, waterproof camera down the pipework to get an up-close view of what's going on underground. This camera records high-quality video footage, allowing the plumber to assess the condition of the drains and identify any problems that may be lurking beneath the surface. From this, the plumber can provide you with a full report on the status of the drainage and estimated rectification costs if required. This knowledge is invaluable, as it helps you make an informed decision about the property you're considering purchasing.

For sanitary drainage, a visual inspection of the septic, grease trap and effluent pit will need to be conducted by a wastewater endorsed plumber to assess its condition.

What can you do if drainage issues are present?

Present the information obtained from Drainage Inspection report to your agent and;

  • Negotiate repairs with the seller,

  • Reduce your offer (to cover future costs of drainage rectification),

  • Or withdraw your offer on the property.

A pre-purchase Drainage Inspection through Macklin Plumbing & Excavation is only $450 + GST. That’s a small cost for peace of mind, one that is a must before you purchase your next property.
