Water hammer
Experience suggests that any rapid change in the speed of
the water flow in a pipe is followed by sudden pressure disruptions.
These disruptions, which comprise quick alternations between overpressure and vacuum,
reach their maximum extent when the water flow is interrupted abruptly
by shutting off a device (valve or tap) or random events such as a pump stopping.

The resulting overpressure spreads at high speed through the flow medium and triggers a series of powerful blows both
to the device that has interrupted the flow of water and to the pipe to which the device is fitted.

The phenomenon described above is known as water hammer
and is often accompanied by vibrations and loud noises.

The extent of the overpressure created is determined by the time it takes
for the devices that cause the change in the flow rate to close
and other additional factors.
In modern plumbing systems, the phenomenon of water hammer occurs ever more frequently because of the increasing use of quick-closing fittings
such as single-lever mixers, electronic valves, ball valves, etc. In fact, because of their extremely short closing times these devices
bring about an immediate interruption to the water flow and thus cause water hammer.
The water hammer overpressure very often reaches high values and causes the following problems:
Broken pipes, circulation pumps, process water tanks, combination tanks, fresh water stations, containers and hoses;
