Pressure surges ocurr in piping systems whenever there are sudden changes in flow resistance from steady operation. Surges can cause significant damage, also at locations far removed from where they are initiated. For large or complex piping systems, this can make their impact challenging to predict without specialist analysis. Dynaflow
