A burst pipe can cause severe water damage within minutes if not handled quickly. Knowing what to do when a pipe bursts in the house can help minimise structural damage, reduce repair costs, and protect your home from mould and electrical hazards. Burst pipes are often caused by corrosion, high water pressure, blocked drains, shifting ground, or ageing plumbing systems. In many homes, the warning signs appear before the pipe completely fails. Understanding the emergency response process and calling a qualified plumber immediately can save you time, money, and stress.  

What Causes Pipes to Burst?  

Burst pipes can happen in both old and modern homes. Several issues contribute to plumbing failures, including:  

Cause 

Description 

Corrosion 

Older metal pipes weaken over time 

High Water Pressure 

Excess pressure stresses pipe joints 

Tree Root Intrusion 

Roots can crack underground pipes 

Blockages 

Clogs increase internal pressure 

Ground Movement 

Soil shifting may damage pipelines 

Poor Installation 

Weak fittings can fail unexpectedly 

Warning Signs of a Burst Pipe Inside Walls  

Many homeowners overlook subtle warning signs until the issue becomes serious.  

  • Unexplained damp patches on walls or ceilings   
  • Bubbling paint or peeling wallpaper   
  • Sudden drop in water pressure   
  • Higher-than-normal water bills   
  • Mould or mildew smells   
  • Strange dripping or hissing sounds   
  • Warped flooring or swollen cabinetry  

Why Hidden Leaks Are Dangerous  

Hidden burst pipes can weaken timber structures, damage insulation, and encourage mould growth. If left untreated, water can also impact electrical wiring and create safety hazards.  

According to the Australian Building Codes Board, water damage is one of the most common building defects affecting residential properties.  

Emergency Steps for Burst Water Pipes  

Shut Off the Main Water Supply  

The first step is to stop the water flow immediately.  

How to do it:  

  • Locate the main shut-off valve   
  • Turn the valve clockwise until fully closed   
  • Check taps to confirm water flow has stopped  

Turn Off Electricity if Necessary  

If water is near electrical outlets, appliances, or wiring:  

  • Switch off the power at the main electrical board   
  • Avoid touching wet electrical surfaces  

Never enter flooded rooms if there is an electrical risk.  

Drain Remaining Water from Pipes  

After shutting off the supply:  

  • Open cold taps first   
  • Flush toilets   
  • Open hot taps to drain remaining water  

This helps relieve pressure inside the plumbing system.  

Contain the Leak  

Use temporary measures to minimise water spread:  

  • Place buckets or containers under leaking areas   
  • Use towels or mops to absorb water   
  • Move furniture and valuables away  

Call an Emergency Plumber Immediately  

Burst pipes require professional repairs. Licensed plumbers use specialised leak-detection tools to locate and repair damaged sections quickly.  

Emergency plumbers in Wollongong and Shellharbour often provide:  

  • 24/7 plumbing response   
  • Leak detection   
  • Pipe relining   
  • Pipe replacement   
  • Water damage assessment  

Document the Damage  

If insurance claims are necessary:  

  • Take clear photos   
  • Record damaged belongings   
  • Keep repair invoices  

This information can assist with insurance processing.  

How Plumbers Fix Burst Pipes Quickly  

Step 1: Leak Detection  

Professional plumbers use:  

  • Thermal imaging cameras   
  • Acoustic leak detectors   
  • CCTV drain inspections  
  • These tools help accurately locate hidden pipe damage.  

Step 2: Isolating the Damaged Section  

The affected pipe area has been isolated to prevent further leakage.  

Step 3: Pipe Repair or Replacement  

Depending on the severity:  

  • Small cracks may be patched   
  • Damaged sections may be replaced   
  • Corroded pipes may require full upgrades  

Step 4: Pressure Testing  

Plumbers test the repaired pipe to ensure there are no remaining leaks.  

Step 5: Restoration Recommendations  

In severe cases, plumbers may recommend:  

  • Water extraction   
  • Drying services   
  • Mould prevention treatments

Why Immediate Plumbing Help Matters  

Delaying repairs can lead to:  

  • Structural timber damage   
  • Foundation issues

  • Mould growth   
  • Expensive renovations  

The Insurance Council of Australia reports that escape-of-liquid damage accounts for thousands of insurance claims annually.
