Inspection & Condition Details:
This item was fully removed from its original box for visual inspection. The pump is clean and appears unused with no signs of prior installation. The unit includes original documentation and two rubber flange gaskets. The outer box shows minor handling and shelf wear. Inline circulator pumps require full system plumbing installation for operational testing, so this unit could not be powered or fluid-tested.
Please refer to the photos for more information.
