HOME 3--Creating the Header for Geothermal Heat Pump System

Creating the Header for Geothermal Heat Pump System for a new home in Stillwater, Oklahoma. 6 boreholes were drilled 300 feet deep, a ground loop installed and the boreholes were grouted. A header connecting all 6 ground loops were installed with reverse return which allows each loop to have the same inlet and outlet pressure. Used to cancel the effects of pressure loss along the header.

Exactly what measures are needed to correct the situation if you encounter air-leaks in joints or elsewhere during pressure-testing? How often does this happen?

@SuperGoogly1

If air-leaks are encountered during pressure-testing than joints are cutout and reassembled. All joints are fused connected underground for header piping and reverse return is used and tested for leaks before covering up. If proper procedures are used for fusion connections then rarely do we have any leaks. If a leak then it is cutout and refused together and checked again.

Cut the fitting out and fuse another fitting in place. You may need to add another piece of pipe if the length if the fitting will not fit. Testing is done before covering with dirt and is critical.

@SuperGoogly1 If it gets stuck pump a little water to help blast it through the mud. Might be difficult to break the duct tape away from the loop, might damage loop in the proses.

GREAT VIDEOS ! Thanks so much for putting these up! By the way, since the grouting tube is so difficult to get to the bottom of the hole after the loop is in the hole, might it be easier and quicker to duct-tape it to the loop and slide it down WITH the loop initially? Thanks again for the terrific videos!
