Water Hammer Is a Warning, Not Just a Noise
Every time water hammer bangs through your pipework, hundreds of kilopascals of shock pressure hit the joints, fittings, tap seats and appliance valves inside your home. It’s the plumbing version of driving with the handbrake on. You may not see the damage today, but it’s slowly working through the weakest point in your system.
The most common cause in Melbourne homes is high mains pressure. Many properties run at 400 to 500 kPa or above, which is enough to make any fast-closing valve produce a serious bang. Other common causes are a failed or missing water hammer arrestor, loose pipes rattling inside wall cavities, or a modern solenoid valve in a washing machine or dishwasher slamming shut.
Fixing it properly means identifying which cause you actually have. A pressure limiting valve won’t help if the issue is a loose pipe in the roof space. An arrestor won’t help if your mains pressure is 20 per cent above the recommended limit. That’s why we test first, then quote, then fix.
Water Hammer Is a Warning, Not Just a Noise
Water hammer is loud, unsettling and slowly destructive. Every bang is a shockwave running through your pipework, loosening joints, damaging tap washers, and putting strain on appliance valves. Left alone, it turns from an annoying noise into a burst pipe or a leaking connection.

Our Water Hammer Repair Services in Melbourne
Water Hammer Diagnosis & Pressure Testing
Water hammer has several possible causes, and guessing the fix is expensive. We pressure test the mains, inspect appliance valves, and check pipework runs to find the real trigger, then quote you a fix that actually solves the problem.
Water Hammer Arrestor Installation
A water hammer arrestor absorbs the shockwave before it can travel through your pipework. We install correctly sized arrestors at the right points in your system, especially near washing machines and dishwashers where the noise usually starts.
Pressure Limiting Valve (PRV) Installation & Adjustment
High mains pressure is the most common water hammer cause in Melbourne. We test your incoming pressure, install or replace the pressure limiting valve, and set it to a safe level that stops the shock without starving your fixtures.
Loose Pipe Securing & Bracing
Copper or PEX lines that rattle inside wall cavities or roof spaces produce a distinctive knocking sound. We locate the loose sections, add proper clips and brackets, and cushion the pipework so it stops moving when water flow changes.
Appliance Connection & Solenoid Valve Repairs
Modern washing machines, dishwashers and toilet cisterns use fast-closing valves that can trigger water hammer on their own. We check the connections, fit arrestors at the appliance, and repair or replace the fittings causing the shock.

WATER HAMMER REPAIRS MELBOURNE
Water Hammer Plumber Melbourne - Real Diagnosis, Lasting Fix
Water hammer is loud, unsettling and slowly destructive. Every bang is a shockwave running through your pipework, loosening joints, damaging tap washers, and putting strain on appliance valves. Left alone, it turns from an annoying noise into a burst pipe or a leaking connection.
Our licensed Melbourne plumbers pressure test the property, isolate the exact cause, and fix the underlying issue rather than just muting the symptom. Whether it needs a pressure limiting valve, a water hammer arrestor, secured pipework or an appliance-side repair, we get you a quiet, protected plumbing system.
Our Water Hammer Repair Process
Diagnose the Real Cause
We pressure test the mains, inspect the pipe runs, and check appliance valves to work out exactly what's triggering the hammer. That tells us which fix will actually solve the problem, not just quieten it for a week.
Fix the Underlying Issue
Where it needs an arrestor, a PRV, pipe bracing, or an appliance-side repair, we carry the common parts and get it done in one visit wherever possible. You get a clear itemised quote before any work begins.
Test and Verify the Fix Holds
We recreate the trigger conditions, listen and feel for any remaining shock, and confirm the system is quiet under load. You get a straight explanation of what caused it and what to watch for going forward.
Why Choose Select Plumbing & Gas for Water Hammer
Licensed Melbourne Plumbers Who Diagnose Before Quoting
Every water hammer job starts with a proper pressure test and pipe inspection, not a guess. You get a clear answer on the actual cause before any work is quoted, so you're not paying for parts that wouldn't have helped.
Repair-First, Not Rip-and-Replace
Plenty of operators default to a full re-plumb because it's the bigger sale. We repair what can be repaired, replace only what genuinely needs it, and give you the honest call either way.
Same-Day Response for Severe Water Hammer
Loud banging shaking your pipework or leaks appearing after a hammer event can't wait. We respond fast across Melbourne with fully stocked vans, so most urgent cases are attended on the same day.
The Right Fix for the Right Cause
An arrestor, a PRV, pipe bracing and an appliance-side repair all solve different problems. We match the fix to what's actually happening in your system, so the hammer stops for good rather than coming back in a month.
Local Melbourne Knowledge of Mains Pressure
Melbourne's mains pressure varies suburb by suburb, and many areas run higher than the recommended limit for household fittings. We know the local numbers, and we set the PRV to the pressure your actual home needs.

Frequently Asked Questions: Low Water Pressure Fix in Melbourne
What causes low water pressure in a Melbourne home?
The most common causes are a failed pressure regulator, blocked or corroded internal pipes, a hidden leak, a partly closed valve, or a mains supply issue. A pressure test isolates the real cause fast.
Why is only my hot water pressure low?
If only the hot water is weak, the fault is usually inside the hot water system, the tempering valve, or the hot water isolation valve, not the house pipework. A plumber can quickly narrow it down.
How do you fix low water pressure?
It depends on the cause. We might replace a pressure regulator, clear a restricted line, repair a hidden leak, or replace a section of corroded pipe. We diagnose first, then fix only what’s actually wrong.
Can you replace my water pressure regulator?
Yes. Pressure limiting valve replacement is a standard job we do across Melbourne. We test the existing valve, set the correct pressure for your fixtures, and replace it where it’s no longer holding.
Yes. A slow underground or wall cavity leak often shows up as low pressure long before it shows as a damp patch. If pressure has dropped without an obvious reason, a leak check is worth doing.
How much does it cost to fix low water pressure in Melbourne?
Cost depends on the cause and the parts needed. We diagnose first with a pressure test, then give you a fixed written quote before any work starts, so you know exactly what you’re paying for.
How do I know if the problem is my pipes or the mains supply?
A pressure test at the meter tells us straight away. If mains pressure at the meter is fine but flow inside the house is weak, the fault is on your side. If pressure at the meter is low, it’s a supply issue.
How long does a low water pressure repair take?
Most residential fixes take one to two hours once we’ve diagnosed the cause. Regulator replacements, leak repairs, and blocked line clears are usually same-visit jobs. Full re-pipes take longer.
