Unfortunately, piping terminology and pool terminology are inverted.

Piping returns, return to the boiler or pump or heater, and supplies carry the fluid where it's going. But, pool returns, return to the pool, and the term "supply" isn't used in that sense. I was a plumber and now I'm a pool guy, so I had to learn both!
