What is Water Hammer?
A sudden increase in water pressure caused by rapid valve closure or pump shutdown, leading to:

Pipe vibrations and damage.
Pressure surges that can exceed system limits.
Component wear and potential pump failure.
Prevention Methods:
Use slow-closing valves to prevent sudden pressure changes.
Install surge arrestors or expansion tanks to absorb pressure spikes.
Ensure proper pump start/stop sequences to reduce shock loads.
