The air chamber will fill back up with air instead of water, hopefully solving the water hammer problem.

What is a water hammer arrestor used for?

Water hammer arrestors are used to absorb the shock when water flowing in a piping system suddenly stops due to fast closing shutoff valves, dishwashers, and clothes washers. This action protects against annoying and potentially damaging effects of water hammer.

3. Replace intake connections.
4. Install water hammer arresters.
5. Secure the pipe.
6. Install pressure limiting valve.
7. Install different taps.
8. Call the plumber.

Where should hammer arrestors be installed?

Exactly where to place the hammer arrestor will depend on the actual piping arrangement. The best places are either close to the pump, isolation or check valve that is originating the hammer, or at more distant points where the pipe changes direction, for example at the top of a pump riser.

Can water hammer damage pipes?

Water hammer is a serious problem that will cause erosion and damage to the pipes, valves, fittings and can cause pipe bursts. Modern plumbing systems are designed with chambers of air to ease the damage caused by water hammers.

How does a water hammer arrestor work on a water pipe?

A hydropneumatic device similar in principle to a shock absorber called a ‘Water Hammer Arrestor’ can be installed between the water pipe and the machine, to absorb the shock and stop the banging. Air valves often remediate low pressures at high points in the pipeline.

How does a water hammer work in a steam system?

In a steam system, a water hammer most often occurs when some of the steam condenses into water in a horizontal section of the piping. Steam picks up the water, forming a ” slug “, and hurls this at high velocity into a pipe fitting, creating a loud hammering noise and greatly stressing the pipe.
