The piping system design due to pressure will experience vibrations due to the excitation force that comes from the pump. Excitation force occurs due to changes in fluid flow velocity. In addition, the length of the pipe and the large number of bends of the pipe due to cross with other installations, cause vibrations in the pipe. vibration analysis in the pipe should not be underestimated, where it is necessary to identify the causes of vibration in the pipe due to flow and placement of good support and the effect of obstacles in the pipe flow to prevent failure of the pipe. In addition, clogging of pipelines can result in reduced system carrying capacity, wastage of energy and resources, and the potential for increased likelihood of environmental and health problems. Therefore, this study will discuss the identification of blockage of water flow in pipes using the vibration method. The excitation force comes from the fluid flow flowing in the pipe, while the vibration response is generated using the accelerometer sensor provided with the FFT Analyzer. Retrieval of data using the accelerometer as a vibration sensor served by Ono Sokki's FFT analyzer which is then analyzed using Matlab. Installation with four supports shows that the resonance that occurs in the installation of two supports can be reduced, but it causes the magnitude of the iron pipe to increase, while the PVC pipe decreases at a frequency of 5 Hz. In general, the result of installing four supports shows that the noise on the PVC pipe is reduced while the iron pipe is getting higher due to the installation of a barrier in the pipe due to water flow. The vibration pattern that occurs uses a harmonic response simulation, the vibration pattern that occurs uses a harmonic response simulation.
