How to Repair a Pressure Governor on a Fire Pump

As portable firefighting systems, fire pumps provide fire fighters the ability to easily transport water to the scene of a fire. Typically classified as either forestry aids for use in wildfires or as additional support for firefighters, fire pumps require regular maintenance to ensure they are working properly. Along with the pump itself, a pressure governor is an essential element to a fire pump as it produces the high pressure necessary to propel water from the fire pump.
