We recently purchased a house with an inground pool. It was already closed for the winter when we moved in so we didn't get any experience with it last year. It is now time to open up and I am clueless at everything I am looking at. I figured out that I have a Hayward pump and found an owners manual online to help me out. I then figured out that I had a Sta-Rite sand filter with a multifunction valve on top. There are miscellaneous pool tools that the previous owner left for us but I'm not sure how any of them are used or hooked up. One is the vaccuum and I think it gets hooked up near the skimmer (which I think I know where it is) but I don't know how. There does not appear to be anywhere to plug it in for the suction. Where does this hook up? Please be kind, I know I'm clueless and could use any help with this.
