Water Hammer Repairs Sydney

Need a water hammer issue repaired? We’re the right plumbers for you!

Plumber For New Taps

A Water Hammer Is That bang in the walls when a tap shuts off

You turn off a tap, or the washing machine finishes filling, and the pipes go off like someone hit the wall with a hammer. That noise is water hammer, and it is not just annoying.
It is a pressure shock travelling through your pipework, and over time it loosens fittings, splits flexible hoses and cracks joints.
 
We diagnose and fix water hammer across the Hills District and north west Sydney.

What causes water hammer

  • A valve closing too fast. When a tap, a solenoid valve in an appliance, or a mixer shuts suddenly, the water moving in the pipe has nowhere to go. That energy hits the closed valve and bounces back through the system.
  • Water pressure that is too high. High incoming pressure makes every shock harder. This is the most common underlying cause we find, and it is also the one that damages everything else in the house.
  • Pipes that are not secured properly. A pipe that can move in the wall will bang against the frame when the shock hits. Sometimes that is the entire problem.
  • Worn tap washers and valves. A failing washer can make a tap shudder as it closes.
  • Appliances with fast acting valves. Washing machines and dishwashers close their inlet valves very quickly, which is why the bang so often happens when they are running.

Why it is worth fixing rather than living with

Water hammer is a symptom, and the pressure behind it is what does the damage. The same shock that makes the noise is working on every joint, fitting and flexible hose in the house.

Burst flexible hoses are the big one. A flexi hose under a vanity that lets go while nobody is home is one of the most common and most expensive water damage claims in Australian homes. High pressure and repeated shock are exactly what shortens their life.

So the noise is the warning. The repair is usually cheaper than the thing it prevents.

We just moved into our new home and walked in to find 2 leaks coming from the downstairs bathroom ceiling. We called The Plumbing Paramedics and they sent Kyle over. He was friendly and a good communicator. He was thorough when seeking to find the leak. He was able to locate the issue in a damaged upstairs toilet by performing a leak detection test. He removed the damaged toilet and installed a new one for us. If you want an efficient plumbing service and clear communication from office staff, call The Plumbing Paramedics.

We recently experienced a plumbing emergency with water leaking from our ceiling and called Plumbing Paramedics for help. Kyle and Josh arrived promptly and quickly identified the source as a burst pipe. They were professional and knowledgeable throughout, taking the time to clearly explain the issue before proceeding, and completed the repair along with installing a new pressure valve in under 90 minutes. As a family with young children, we greatly appreciated their efficiency and the peace of mind their work provided. We highly recommend them and will use them again!

How we fix A Water Hammer Problem

Water pressure test

We start by measuring the incoming pressure. If it is too high, that is usually the root cause and everything else is a symptom.

Pressure limiting valve

Where pressure is the cause, fitting or replacing a pressure limiting valve fixes the hammer and protects the rest of the plumbing at the same time. Our pressure reducing valve page covers this in detail.

Water hammer arrestors

Where the shock is coming from a specific appliance or valve, an arrestor fitted at the right point absorbs it. Fitted in the wrong place it does nothing, which is why the diagnosis matters more than the part.

Securing loose pipework

Where the banging is a pipe moving against the structure, we secure it properly.

Tap and valve repairs

Worn tap washers and failing valves get replaced.

Checking your flexible hoses

While we are there we check the flexi hoses, because water hammer and old hoses are a bad combination.

Get the banging sorted With A Local Plumber

We work right across Sydney and the Hills District, and we aim to get to you quickly, with same-day service available in many cases.

Frequently Asked Water Hammer Questions

It will not hurt you, but it damages plumbing over time. The pressure shock works on joints, fittings and flexible hoses, and a burst hose causes serious water damage.

Appliances close their inlet valves very fast, which creates the sharpest shock. If it only happens with one appliance, the fix is usually targeted rather than whole of house.

You can check that accessible pipes are secured. The pressure side needs a licensed plumber, because it means working on the mains and fitting a valve correctly.

Sometimes. If the underlying cause is high pressure, an arrestor treats the symptom while the pressure keeps working on everything else. We test the pressure first so you are not paying for a part that will not solve it.

Most water hammer jobs are done in a single visit once we have diagnosed the cause.

Usually yes. The cistern inlet valve closing is the trigger, and the cause is normally the same.

It depends on whether it is a valve, an arrestor, securing pipework, or a pressure limiting valve. We test first and tell you what it needs before doing anything.
