The plumbing of our pool and spa is somewhat similar to this:
Instead of "Spa Make-up" our valve is labeled "Spa Bypass" and instead of connecting to the Spa Return line, it has it's own line returning directly to the Spa.
As far as I can tell, it basically just shuts off return flow to the spa... which seems redundant since that's what the Pool Return/Spa Return valve does.
What am I missing?
