How can water hammer damage pumps and pipes?
If the wave is sharp and it passes through pipe bends, the pressure step change can cause out-of-balance forces which move the pipe.

Why do I get water hammer in my water system?
The valves will generally be open when the water hammer shock wave travels through the pipework and the shockwave could well ‘rattle’ the valve handle and a loose jumper. If you’ve never had water hammer and one day you suddenly experience it out of the blue, then it’s likely your water system’s air chambers are blocked.
Why is the water hammer in my toilet so loud?
