Abstract: The present invention relates to a method of mounting a pool skimmer to a wall of a saltwater swimming pool to prevent rusting of the wall in the skimmer mounting area. This is accomplished by interposing insulators between the corrosive salt water and the holes necessary to mount the skimmer. The front bracket of the skimmer of the present invention has cavities to accommodate the interposed insulators. The insulators are a combination of one-piece screws with metal washers, and rubber-like washers made of a TPE resin. The rubber-like washer IS sandwiched inside the cavity of the front bracket by the screw's metal washers. The interposing insulators resist salt water from leaking down a screw's threads and attacking the integrity of the metal wall of the swimming pool. The insulators form a watertight seal around the screw thus preventing salt water from corroding the wall of the metal swimming pool.
