I've seen banding and bonding. Not sure why there are both, but...it's the same thing. Since I pull off all my plumbing for the winter, I have a ball valve, quick release under my skimmer, another BV/QR at my low drain, a QR at my return, a BV/QR for each of my solar circuits, a BV/QR for the solar panels in general, a BV/QR between the SWCG manifold and the return, a QR on either side of the SWCG manifold, a QR where the return exits the filter, a BV/QR where the drains reach the pump, a QR on top of the pump and a QR on the filter from the pump, and a QR on the waste line.

Everything pops off for winter storage.
