Water moving through a pipe has momentum. When a valve closes fast — a washing machine solenoid, a dishwasher, a quarter-turn tap — that moving column stops almost instantly and the energy goes into the pipework as a pressure spike.
The bang is that spike travelling through the system. It is the same physics that bursts pipes, just smaller.
Repeated shock loading works joints loose over time. Water hammer is a common contributor to leaks that appear years later at a fitting nowhere near the noisy appliance.
It also tends to get worse, because each event loosens things slightly further.
Arrestors — small devices with an air chamber that absorb the shock — fitted near the offending appliance. This is the proper fix and it is usually straightforward.
If the whole house hammers, incoming pressure is often too high, and a pressure limiting valve at the meter addresses the cause rather than the symptom. Loose pipes rattling in wall cavities can also amplify the noise, and clipping them helps.
Turning taps off more slowly works, but it is not a fix, it is a habit you cannot impose on a washing machine. Old advice about draining the system to recharge air chambers applies to a design of plumbing most houses no longer have.

Where this job typically sits. Access is usually a bigger cost driver than size.
| Job | Indicative price | What moves it |
|---|---|---|
| Standard call-out and first hour | $150 – $300 | Business hours. Most plumbers charge a call-out that includes some labour. |
| After hours or emergency call-out | $250 – $500 | Nights, weekends and public holidays carry a premium. Ask before you agree. |
| Clear a blocked drain (machine) | $250 – $600 | Depends on access and how far down the blockage sits. |
| Drain camera inspection | $250 – $450 | Often the difference between guessing and knowing. Sometimes bundled with a clear. |
| Replace a hot water system | $1,500 – $3,500 | Electric storage at the lower end. Gas and heat pump run higher, plus any compliance work. |
| Repair a hot water system | $200 – $700 | Elements, thermostats and valves are usually worth repairing. A rusted tank is not. |
| Burst pipe repair | $300 – $900 | Accessible pipework at the lower end. Under a slab is a different job entirely. |
| Pipe relining, per metre | $400 – $900 | More than a clear-out up front, less than excavation, and it lasts. |
| Replace a tap or mixer | $150 – $400 | Plus the tapware. A dripping tap is often just a washer. |
Prices here are indicative only. What a plumbing job costs depends on what is actually wrong, how accessible the pipework is, whether it is after hours, and what has to be replaced rather than repaired. You get a firm price from the plumber after they have seen it.
Water escaping, no water at all, or sewage backing up — the calls that cannot wait.
