How are the pipes joined?
Geothermal pipes must be connected by fusion. There are other options for connecting but we only use fusion because it is the strongest and lasts the longest. Barbed fittings, clamps and glued joints are never to be used in a geothermal heat exchange system because they will cause the joints to fail and ultimately, you’ll have a leak. When joined correctly, especially with thermal fusion, the joints become even stronger than the original pipes.
