have ground on the panel to the steel water pipe
and another by the A/c outside and one for the att phone cable and internets
the last two are just bars driven into the dirt
the panel ground is a couple of feet inside the garage so connected to 20 ft of 3/4 pipe in the ground under a slab then new PVC pipe to the meter and main water lines
is the 20 ft of pipe enough for a good ground for the el panel ?
