2. Water hammer - Wikipedia

   en.wikipedia.org/wiki/Water_hammer

   The following characteristics may reduce or eliminate water hammer: Reduce the pressure of the water supply to the building by fitting a regulator. Lower fluid velocities. To keep water hammer low, pipe-sizing charts for some applications recommend flow velocity at or below 1.5 m/s (4.9 ft/s). Fit slowly closing valves.

3. Hydropneumatic device - Wikipedia

   en.wikipedia.org/wiki/Hydropneumatic_device

   Hydropneumatic water hammer preventers are chambers of sufficient volume to allow an extension of time in which a given flow may be accelerated or decelerated without sudden large change in pressure. See also expansion tank. When shock waves of an incompressible fluid within a piping system exist, especially at a high velocity, there is a high ...

4. Backflow prevention device - Wikipedia

   en.wikipedia.org/wiki/Backflow_prevention_device

   In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened).

5. Check valve - Wikipedia

   en.wikipedia.org/wiki/Check_valve

   Undetected, water hammer can rupture pumps, valves, and pipes within the system. [9] The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank drains and the flapper falls due to gravity.

6. Flushometer - Wikipedia

   en.wikipedia.org/wiki/Flushometer

   A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush. The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down.

7. Snubber - Wikipedia

   en.wikipedia.org/wiki/Snubber

   A snubber is a device used to suppress ("snub") a phenomenon such as voltage transients in electrical systems, pressure transients in fluid systems (caused by for example water hammer) or excess force or rapid movement in mechanical systems.
