The paper employs the method of characteristics to solve the transient flow control equations of pipelines, verifies the accuracy of the numerical method using data from existing literature, and establishes a simple pumping station water supply system. It investigates the detection of blockages and leaks in the pipelines of the system while considering variations in pipe elevation and pump boundary conditions. It is found that pressure waves generated by rapid closure of end valves reflect when they reach the locations of blockages and leaks. The reflected pressure waves back to the valvecause abrupt changes in pressure signals, and different types of faults result in different forms of abrupt changes. Based on the time of the abrupt change and the wave speed of the pipeline, the locations of blockages and leaks can be calculated. The final research results confirm that the method demonstrates high precision in locating blockages and leaks across different parameters, with detection errors below 1% under ideal conditions. Moreover, it effectively identifies blockages and leaks at points of pipe elevation changes and pipe connections. Importantly, it displays strong applicability even in scenarios where both blockages and leaks coexist within the system.
