这个叫Water hammering
Water hammer
What is it?
Water hammer is a banging or vibrating sound that can occur
in your water service pipe.
What causes it?
It mainly occurs when a tap or valve is suddenly closed,
causing hydraulic shock waves to be transmitted through
the pipe.
How can I minimise it?
Remove air from your pipes by turning on the tap found at
the highest point on your property. If the problem persists,
consult a licensed plumber to assess the situation.
Causes of water hammer
• Air in pipes
• Plumbing design faults
• Wrong types of taps used for particular fittings
• Restrictions in flow caused by kinks or corrosion in pipes
• Automatic valves on sprinkler systems
• Mains pressure on gravity hot water services
• Faulty float controls in toilet cisterns
• Starting and stopping of pumps
Can it cause damage?
While not common, water hammer can cause pipes to burst
if a weakness exists in your internal pipework, such as at joins
or where there has been some corrosion. Water hammer
can also cause pipes to move if they are not well secured,
resulting in fatigue cracks or friction holes.
