Does this mean that if I assume the only movement in the pipe to be a fire hydrant, and that hydrant or valve hydrant were closed quickly that a pressure surge of some PSI (calculated by PUMPDESIGNERS calculation) will travel back through the main at ~0.7 fps back my connection point...

The surge I am worried about is the pressure that will develope from the quick closure of a fire hydrant or 6-inch hydrant valve. the 24-inch mainline gate valves take over 200 turns to close so they do not...
