Abstract
A decalcification tool for cleaning chemical feed injection port includes a rod having a first end, a second end and a handle bar segment between the first end and the second end. The tool includes a stopper having a threaded exterior surface for mating with an orifice of an injection port and being installed on the rod at a location below the handle rod segment and above the first end. The stopper is slidable along a portion of a longitudinal axis of the rod. The tool includes a paddle integrated with or affixed to the first end of the rod and configured to be inserted into the injection port. Rotation of the rod causes the paddle to rotate within the injection port such that the paddle applies impact forces to chip, crack, or breakup debris along an interior surface of the injection port.
