I'm brand new to owning and caring for a pool. Ive recently moved into a house with an older inground pool (about 25 years old I think). The concrete deck around the pool was shifting and in poor condition so I decided to have new concrete poured. During the excavation they knocked the skimmer off the pipe and doing so, the pipe got filled with rocks and sand. My dad and I dug out the skimmer, removed it and exposed the pipes. There is a big black pipe (that is the one that is filled with rocks) and a smaller white one that is capped. .hopefully you understand what I'm talking about, because I'm not sure that I do
My questions are (a) what is the function of those pipes, (b) how on earth do I unclog it? The stones and sand are packed in really firmly.
Thank you so much
