Taps, Washing Machines and Loose Pipes
Water hammer is a pressure jolt that races along a pipe line the instant flowing water is stopped dead, heard as a thud or a knock. A tap closed too fast sets it off, and so does a washing machine or a dishwasher snapping its fill valve shut, an unclipped run, or a strong supply.
The valve is where it starts. A solenoid inside an appliance closes in a fraction of a second, and the water column behind it has nowhere to go, so it slams into the fitting.
Anything that shuts quickly can set it off:
- a tap flicked closed with a wrist
- an appliance finishing its fill cycle
- a toilet cistern cutting off mid-refill
- a garden tap running off a hose
Loose runs make the bang louder. Many postwar weatherboard and fibro homes here carry supply lines under the floor rather than through a slab.
A run with a missing clip knocks on the joists every time the jolt arrives, and under-floor runs are exactly where clips work loose unseen.
Fixes From Pipe Clips to Arrestors
The fixes run in order: re-clip the loose runs, test and settle the supply pressure, then add an arrestor or revive an air chamber beside the slamming valve.
Each one targets a different cause:
Clips and brackets
hold the pipe still, so even a strong jolt has nothing to knock against.
A pressure check
rules out a strong supply, the factor that turns a knock into a crash.
An arrestor
is a sealed device in the line that absorbs the shock when a valve closes quickly, doing the job an air chamber used to.
An air chamber
is a short capped length of pipe above a valve, holding an air pocket as the cushion. In older homes the pocket waterlogs and stops working, so a plumber drains or renews it.
Placement matters. The arrestor goes beside the quick-shutting valve that starts the bang, often the laundry machine supply, because the shock begins there and the cushion has to sit next to it.
A licensed plumber does all of this work. None of it appears on the QBCC's short list of unregulated jobs, which covers items like swapping a tap washer.
One check needs no tools. Close your taps slowly and use a soft-close or slow-fill setting on an appliance that offers one. If the bang disappears, fast closing was the cause.
Is Water Hammer Harmful
Yes, repeated jolts work joints and fittings loose and can end in leaks, so the noise deserves attention rather than a shrug. Left alone, the shock eventually damages connections, and in the worst case a joint lets go.
Ring a plumber when any of these appear:
- the noise grows louder or more frequent
- pipes visibly shake when a valve closes
- leaks, moisture or corrosion show at fittings
- more than one part of the house is affected
- the water pressure seems very high
The older housing here raises the stakes. Unrenovated 1950s houses around the suburb still run galvanised steel supply lines, and that pipe scales up inside and fails at its threaded joints.
A jolt working on already tired threads is a fair reason to act, and repiping old pipes is the bigger job that follows if the line has had its day.
Water Hammer or Another Pipe Noise
A thud at the instant a valve shuts is hammer. A shake that sounds only while water flows points to loose runs or strong pressure. A tick or creak as pipes heat up and cool down is expansion movement, the pipe changing length with temperature.
Timing is the clue. Noise while the water runs means the pipe is moving in its clips or the pressure is high, which is a different fix from hammer.
The tick is different again. Pipes slide in their brackets as they warm and cool, and that creak is movement, not shock.

Water Hammer Questions From Geebung
Call (07) 3523 7172Why do my pipes bang when I turn a tap off in Geebung?
Water hammer is the cause. Moving water halts dead when a valve shuts, and the stop sends a pressure jolt down the line that lands as a bang. Quick-shut taps, appliance fill valves, loose runs and strong supply pressure are the usual triggers.
Why do I suddenly have water hammer?
Something changed. A newly fitted appliance or tap, a clip that has worked loose under the floor, or supply pressure that has crept up can all start the noise out of nowhere. A licensed plumber checks the clips first, then tests the pressure.
What is a water hammer arrestor and where does it go?
A sealed cushioning device plumbed into the line, an arrestor absorbs the jolt of a fast-closing valve. It sits beside the tap or appliance valve that slams, often the laundry machine supply, because the shock starts there.
Can high water pressure make pipes bang?
Yes, strong supply pressure is a common trigger and it makes the bang worse. A licensed plumber can test the pressure and adjust it. Urban Utilities designs its network to a maximum of 550 kPa, though higher pressures do occur in some low-lying areas.
How long does it take to fix banging pipes?
The time depends on the cause we find, how many taps or appliances are involved, and how easily the pipes can be reached under floors or inside walls. A fixed quote confirms the scope before anyone picks up a tool.
