Water bonding fitting for spa and pool

[Nateski]

Hey folks,
I'm working on my plumbing to connect all my equipment for a new inground pool and spa. I need to install a water bonding fitting in the suction line to bond my water to everything else (perimeter, metal within 5 ft, etc). I understand this should be BEFORE any jandy valves and the pump so any water is always bonded. Since I have suction lines coming from two separate water sources (spa/pool) that are not normally connected, it seems I'm going to have to have two fittings and bondings. Is there a way this is normally handled instead of two separate pvc fittings with screw in bonding units?

Typically only see one bonding fitting on multi pump systems within a single body of water.

I'm installing the bonding fittings just before the pump, above ground in the equipment area. I'm using just a single pump (3HP) for both the pool and the spa (typically not with spillover from the spa, except for the months we are not in state). My thinking is that bonding is all about eliminating any potential voltage differences around the pool and water. So, if only the pool OR the spa suction line has a bonding fitting, then the other body of water is unprotected (since the suction line are continuous only to the respective bodies of water). Since they are two separate bodies of water with no direct water connection, it seems like I'd have to bond both water sources. But, hey, I'd never heard of equipotential bonding before I started building a pool... so I could be way over-thinking this (par for the course with me)!
