there are two pvc pipes exiting from the pool pump

All the pumps I know of (and I have plenty) have
only one pipe exiting the pool pump.

Maybe a picture will help us?

I know you folks in California are free thinking radicals, but
how in the hell do your pool pumps work with only one pipe?

Reading comprehension? one pipe "exiting" the pool pump
(and one ingress pipe, not discussed).
