This is a strange situation, but I'll go ahead and hope someone can help. I just bought a house with an inground pool last winter so this is my first time closing. I have my return lines and skimmer line blown and plugged. When I blow out my return lines through the top pipe connected to the filter valve, water comes out of a small plastic pipe underneath my disconnected pool slide. I have no idea where this water is coming from or what its functin would be.
Also when I was blowing the lines, I noticed a line hole in the pool about 7 inches below where the slide is that seems to have no function. When I first opened the pool, it was plugged but seemed to serve no function all season. I blew air directly into it and nothing I could see occurred. Just to be safe, I sucked any possible water that might have been in there and plugged it ASAP. If anyone has a clue, please let me know. Thanks.
