Buying a home is one of the biggest investments you’ll ever make, and while most buyers focus on the roof, layout, and cosmetic finishes, it’s equally important to inspect the property’s plumbing. Hidden plumbing issues can lead to unexpected repair costs, water damage, and ongoing maintenance headaches after settlement.
Before signing on the dotted line, take the time to check these eight important plumbing-related items.
1. Check the Water Pressure
Poor water pressure can indicate blocked pipes, hidden leaks, failing pressure-reducing valves, or ageing plumbing infrastructure. Turn on taps throughout the home and test showers to ensure a steady flow of water.
Low pressure may seem like a minor inconvenience, but it can often point to larger plumbing issues that require professional investigation and repair.
2. Inspect for Leaks and Water Damage
Look closely under sinks, around toilets, behind washing machines, and near hot water systems for signs of leaks. Water stains, mould, peeling paint, swollen cabinetry, or musty smells can all indicate ongoing moisture problems.
Even a small leak can cause significant damage over time and may require costly repairs if left untreated.
3. Assess the Hot Water System
A hot water system replacement can be a significant expense, so it’s worth checking its condition before purchasing the property.
Look for:
- Rust or corrosion
- Water leaks around the unit
- Unusual noises
- Insufficient hot water
- The age of the system
Most hot water systems have a typical lifespan of 8-15 years depending on the type and maintenance history.
4. Test All Drains
Slow-draining sinks, showers, baths, and floor wastes can indicate blockages or damaged drainage pipes.
Run water through multiple fixtures and observe how quickly it drains away. Gurgling sounds or unpleasant odours can also indicate underlying drainage problems that may require professional attention.
5. Examine the Sewer System
Sewer repairs can be one of the most expensive plumbing issues a homeowner faces.
Warning signs include:
- Frequent drain blockages
- Sewage smells around the property
- Soggy patches in the yard
- Slow drains throughout the home
Older homes may have ageing earthenware pipes that are prone to cracking, collapse, and tree root intrusion.
6. Check the Stormwater Drainage
Queensland’s heavy rainfall can put a property’s drainage system under significant pressure.
Inspect:
- Downpipes
- Stormwater pits
- Kerb outlets
- Surface drainage
Look for signs of water pooling, erosion, or previous flooding issues. Poor stormwater management can result in property damage and ongoing maintenance costs.
7. Inspect Exposed Pipework
Take note of any visible plumbing pipes around the home, under sinks, beneath the house, or in utility areas.
Look for:
- Corrosion
- Rust
- Temporary repairs
- Poor workmanship
- Ageing pipe materials
Older galvanised steel pipes can suffer from internal corrosion, leading to restricted water flow and potential failures.
8. Check Water Tanks and Pumps
Many Queensland homes utilise rainwater tanks for gardening, toilet flushing, or household water supply.
Inspect the condition of:
- Rainwater tanks
- Tank stands
- Pipe connections
- Water tank pumps
A failing pump or damaged tank can reduce system performance and lead to unexpected replacement costs shortly after moving in.
Why a Plumbing Inspection is Worth It
A building inspection is an important step in the buying process, but many plumbing issues can remain hidden without a dedicated plumbing assessment.
Having a licensed plumber inspect the property’s water, drainage, sewer, stormwater, and hot water systems can help identify potential problems before you commit to the purchase. The small cost of an inspection can save thousands of dollars in repairs later.
