Bonding your pool is a safety measure to prevent accidentally getting electrocuted or seriously injured. You need to create a field around your swimming pool by attaching the bonding wire to the metal deck, pool equipment, metal pool wall, and even the water. By doing this you prevent those about the pool or those in the pool from being able to reach a different potential. Lastly, it is the law! Local state and federal building codes require all permanent above ground pools to get correctly bonded.
