I'm planning to make the switch from toting bottles of liquid chlorine to a SWG and new variable speed pump this spring, while keeping my old sand filter. I plan to pour a new equipment pad for this...the original one is just barely large enough to fit everything on to. I want a little more room to maneuver around. My questions are about the bonding. There is a #8 solid wire that comes out of the ground right beside the existing pad that connects to the pump motor housing. When I break up the old pad should I expect to find a wire tied into the pad itself, considering there's either rebar or mesh within the pad? If so I want to remain conscious of that when I'm demoing the old pad. If not, should I tie into the existing wire and connect it to any metal reinforcement that goes into the new pad? Also, considering the location of the existing wire, when I pour the new pad the wire will basically be surrounded by concrete. Is that okay? should I put some type of protective sleeve over the section of wire that will be exposed to the concrete?
