1. A method for rejuvenating a ground electrode assembly, the method comprising:
removing the ground electrode assembly from a mounted position in a plenum base, wherein the ground electrode assembly comprises a housing and a porous electrode positioned in the housing, and at the mounted position the ground electrode assembly is in a mounting receptacle of the plenum base and the electrode is in electrical contact with a ground circuit in the mounting receptacle, and wherein removing the ground electrode assembly comprises moving the electrode out of electrical contact with the ground circuit in a non-destructive manner;
threadably mating the ground electrode assembly with a vessel body defining an interior chamber, wherein the electrode is disposed proximate an outer surface of the vessel body and distal the interior chamber, and wherein the vessel body comprises a fluid port disposed opposite the electrode;
connecting the fluid port to a pressure-applying device;
immersing the ground electrode assembly in a rejuvenating fluid for a period of time; and
activating the pressure-applying device to perfuse the rejuvenating fluid through the electrode.
