This video reviews the Power Flushing Process when flushing and purging a geothermal closed loop system. Power Flushing is a technique that can be utilized to help purge air from a ground loop when the standard flushing procedure does not eliminate all air from the loop. This procedure uses the flush cart pump and municipal water pressure together to provide maximum system pressure to compress and purge air pockets. This procedure assumes that the standard flushing/purging procedure has been completed. Review Geo-Flo’s video on flush cart operation for more information. In addition, there is a step-by-manual available online at Geo-Flo’s website (www.geo-flo.com) in the literature section
