A method of securing a filter element within a pressure vessel without a user breaching a plane of the pressure vessel is provided. The method includes attaching a filter locking nut to a removal/installation tool, wherein the removal/installation tool comprises an elongated body, inserting the filter locking nut into the pressure vessel, securing the filter locking nut to a threaded rod to secure a filter element in place, detaching the removal/installation tool from the filter locking nut, and removing the removal/installation tool from the pressure vessel. At least a portion of the elongated body of the removal/installation tool extends outside of the pressure vessel for the duration of the attaching, inserting, securing, detaching, and removing steps.
