Many people believe that they don’t have to bond their swimming pool water if they have a fiberglass pool or a vinyl liner pool. However, all swimming pools are required to have bonded water. Unfortunately the way the code is written, it talks about bonding to the grid. With modern pools, which have no metals touching the water, there is no way to bond the water to the grid. Therefore, you need an extra stainless steel bond kit (Burndy Water Bug or Burndy Water Bonding Ground Kit) to make sure your water is safe to use.
