A New Look at a Water Hammer Arrestor 

Wow! You made this very understandable! Thank you.

Thank you for your effort , it is really helpful

That last oops was perfect. It illustrates how water hammer can be detrimental, especially to imperfect joints that was not cerrectly installed, behind the walls.

Great vis, however, you should show the deleted scene of the pipe bursting/separating. This would help emphasise your point. Oops, I saw it very cool... So much for patience...

Hi, one question, the pressure peak is the same with and without arrestor?

Is the piston really needed?
