I have a fairly new pool, this will be our 3rd year with it. I am trying to add a Hayward Aqua-trol and I am stumped at this bonding loop. From what I can tell we should already have one for our pool to pump? However, we do not and that is how the professional installed it. So my question is do we need one now? Does just adding the SWG change this or should there have been one all along? And if anyone has pictures of what this looks like done please can you post them? Thank you!!
