I am currently working on a pool that the Builder hooked up the equippotential Bond to the house service main grounding electrode via #8 bare copper. However the House service panel is about five to six feet from the edge of coping from the pool. Very old pool and house. the grounding electrode fell within the perimeter of the pool therefore he felt it should be attached. Is this an issue? Or should I detach the gec connected to the grounding electrode and drive a new rod establishing a new grounding system for the service? Thanks.
