Hello Donna and thank you for your question. When you look down into your pool skimmer, you may see two holes, one at 12 o'clock and another opposite hole, at 6 o'clock. This gives the pool builder some flexibility in how to connect the plumbing pipes underneath the skimmer. They can run a pipe from the main drain into the front hole of the skimmer, and then the back hole is the suction pipe that goes to the pool pump.This reduces costs, compared to running a separate main drain pipe, all the way back to the pump. In your pool, the second pipe is likely not connected to any plumbing and is therefore not functional. Thank you, Alan
