Newb here from Puyallup, WA. We were given a 3 year old only used two summers from a good friend that was moving out of state that has a in ground pool so they gave this one to us. They have everything except the owners manual with a part list. How do I know I have everything needed to set up this pool. They have the installation DVD but that isn't much help I just want to know I have all parts before I get going.
