AMCImportant procedure to follow when filling the tank

When filling the bending tank and/or the straightening pvc pipe it is crucial that all air is out of the piping system before the heaters and pumps are left on without direct supervision. It was found that adding any substantial amount of tap water to the redesigned system, to fill either the tank or the pipe, allows small air bubbles to collect in the pipes. The small air bubbles, at first, are not an issue as they do not impede water flow through the system. After a number of minutes, however, the air bubbles coalesce into fewer big bubbles that do block the flow of water. Because of this, the tank should be emptied only when necessary. If it is crucial to empty the tank, then this procedure (and great diligence) should be followed when filling it again. If this procedure is not followed, chances are good that you will break one or more pieces of equipment!
