Common Causes of Water Leaks
Water leaks can develop for a range of reasons, from ageing pipework through to excessive water pressure and environmental factors. Identifying the underlying cause is essential to delivering an effective, long-term repair.
Ageing or Corroded Pipeword
Older plumbing systems can deteriorate over time, increasing the risk of leaks, reduced performance and pipe failure.
Electrolysis or Material Fatigue
Chemical reactions and long-term material stress can weaken pipework, leading to hidden leaks and structural deterioration.
High or Fluctuating Water Pressure
Excessive or fluctuating water pressure places ongoing stress on plumbing systems, increasing the likelihood of leaks and pipe damage.
Tree Root intrustion
Tree roots can infiltrate underground water mains and pipework, causing cracks, restrictions and water loss.
Faulty Joints & Connectors
Worn or poorly sealed joints may allow water to escape, resulting in concealed leaks and progressive property damage.
Long-term stress from Pressure Surges
Repeated hydraulic pressure surges place stress on plumbing infrastructure, contributing to leaks, joint failure and long-term system deterioration.
Professional leak detection identifies the underlying cause of water loss, allowing targeted repairs that restore system integrity and help prevent recurring issues.

Signs You May Require Leak Detection
Water leaks often develop gradually, with early warning signs appearing long before major damage becomes visible. Recognising these indicators and arranging prompt leak detection can help minimise structural damage, water wastage and costly repairs.
-
Rising Water Bills
Unexpected increases in water usage may indicate a concealed leak within your plumbing system.
-
Damp Walls, Ceilings or Floors
Persistent dampness can be an early sign of hidden pipe leaks behind walls, beneath floors or within ceilings.
-
Mould & Persistent Moisture
Ongoing moisture creates conditions for mould growth and may indicate an unresolved plumbing leak.
-
Cracking Paving or Subsidence
Leaks beneath the ground can wash away supporting soil, leading to movement, cracking or surface subsidence.
-
Continuous Water Meter Movement
If your water meter continues running while no fixtures are in use, a concealed leak may be present.
Prompt diagnosis allows leaks to be accurately located and repaired before they escalate into significant structural or financial issues.

Pressure Testing
Controlled pressure testing verifies system integrity and helps identify hidden water loss within the plumbing network.
- 03
Moisture Detection
Professional moisture detection equipment identifies concealed dampness behind walls, beneath floors and within structural elements.
- 04
Non-Invasive Location Methods
Advanced diagnostic techniques accurately locate leaks while minimising disruption to surrounding property and infrastructure.
- 05
Targeted Repairs & Verification
Where repairs are required, we complete targeted pipe repairs or sectional water main replacement before verifying system performance.
All diagnostic investigations and repair works are completed in accordance with AS/NZS 3500 and relevant Victorian plumbing requirements, ensuring accurate leak detection, compliant repairs and long-term system reliability.

Water Hammer Repairs Melbourne
Newlands & Knights provides expert water hammer repairs in Melbourne for residential and commercial properties.
Water hammer is a hydraulic pressure surge that occurs when water flow is abruptly stopped or redirected. While often dismissed as normal pipe noise, it can place significant stress on plumbing infrastructure.

What Is Water Hammer?
Water hammer typically presents as:
-
Banging or knocking pipes
-
Vibrations within walls
-
Sudden pressure fluctuations
Left unresolved, it may contribute to joint failure, leaks and pipe damage.
Water Leak Detection Melbourne
Causes of Water Hammer
Water hammer is typically caused by changes in water pressure or the way water moves through your plumbing system. Identifying the underlying cause is essential to implementing an effective, long-term solution.
Accurate diagnosis is essential before implementing corrective measures.
-
Rapid shut-off valves
Valves that close suddenly can create hydraulic shockwaves, resulting in banging pipes and pressure surges.
-
High water pressure
Excessive water pressure increases stress on plumbing systems and can contribute to recurring water hammer.
-
Inadequate pressure reduction valves
Poorly adjusted or failing pressure reduction valves may allow damaging pressure fluctuations to occur.
-
Poor pipe support
Pipework that is not adequately secured can move when pressure surges occur, creating knocking sounds and vibration.
-
Faulty tap cartridges or fixtures
Worn or defective taps, valves and plumbing fixtures can contribute to pressure changes throughout the system.

Water Hammer Solutions
Every water hammer issue requires a tailored solution based on the condition of your plumbing system. Following a comprehensive assessment, our licensed plumbers implement targeted repairs and pressure management strategies designed to eliminate hydraulic pressure surges and protect long-term plumbing performance.
-
Water Hammer Arrestors
Install specialised water hammer arrestors to absorb hydraulic shock and reduce damaging pressure surges.
-
Pressure Reduction Valves
Install or adjust pressure reduction valves to maintain stable water pressure throughout the plumbing system.
-
Pipe Securing & Stabilisation
Secure and stabilise loose pipework to minimise movement, vibration and knocking noises.
-
Valve & Fixture Replacement
Replace worn valves, tap cartridges and plumbing fixtures contributing to pressure fluctuations.
-
System Pressure Balancing
Optimise water pressure across the plumbing system to improve performance and reduce hydraulic stress.
Every solution is tailored to the underlying cause of the problem, ensuring hydraulic pressure issues are resolved safely, effectively and with long-term reliability in mind.

When to Seek Professional Assistance
Water hammer is more than an occasional plumbing noise. Repeated pressure surges can place unnecessary stress on pipework, valves and plumbing fixtures, increasing the risk of leaks and long-term system damage.
