1. A method for minimizing over pressurization during a pressure test of a fluid distribution system comprising a plurality of pumping units in fluid communication with a wellhead via a manifold, the method comprising:
pressurizing the fluid distribution system with a fluid using an initial number of pumping units to an initial predetermined pressure; and
further pressurizing the fluid distribution system with the fluid using a final number of pumping units to a final predetermined pressure,
wherein the final predetermined pressure is greater than the initial predetermined pressure,
wherein the final number of pumping units is less than the initial number of pumping units,
wherein the final number of pumping units is operated continuously, from pressuring with the initial number of pumping units to the initial predetermined pressure, until the final predetermined pressure is obtained, and
wherein a subset of the initial number of pumping units is no longer pumping at the final predetermined pressure and the subset is not subject to a backlash force produced by a pressurized fluid from damaging one or more drive shafts of the subset.
