I have an above ground swimmimg pool that I need to bond but upon starting this job I discovered that the support posts on the pool are not metal at all but actually plastic. I can bond the pump, the outlet, the pool water, and the earth around it but the posts themselves have no metal to speak of. However the liner bead, post top mounts and wall bottom rails are steel. With plastic posts how do I bond the top and bottom pool steel together?? Has anyone else encountered a pool install like this??
