ABSTRACT:
A system for installing sub-surface fluid transport tubing and pressure testing coupling seals in a vertically oriented geothermal heating/cooling system installation, and particularly in a direct exchange system installation, includes providing an elevated containment area, that has a confined space opening, supported by extensions/poles, within which opening an upper portion of the fluid transport tubing segment, to be installed within the borehole, can be positioned and contained. The system further includes pressure testing above-ground segmental coupling seals, by using moderate gas pressure applied via temporary gas hose and plug connections to respective ends of the operatively connected fluid transport line set.
