The phenomena is due to a sudden increase in pressure wave, where pressure wave could either be a positive or negative valve. The effect of this phenomena starts with a vibrations occurred in the system to a crack in the pipe wall due to the great amount of pressure wave. The valve closure timing variations are 1, 2, 3, 4, 5, 6, 7, 8,9 and 10 seconds with three spot point for dat collection: point 1 (near the valve), point 2 (centre of the valve), point 3 (near the reservoir). The final result experiment for characteristic pressure, radial vibration, and aksial vibration of water hammer is decrease for time function and distance function, inadditin to material variation of experiment is material with higher elasticity will produce biggerdeformation when occur water hammer phenomena.
