HI! My husband and I are wanting to hard plumb our 26x52 Intex pool. Right now, it's basic, still have the intex pump, and hoses. We have a Hayward vari-flo sand filter we are hooking up, and my husband wants to hard plumb and add a fountain while we are doing that. The only question he really has is for the setup/ and fittings that go to the pool itself? If anyone can give me step by step fittins, and/or pictures, that would be so helpful!! Thanks!!!!
