I bought a 1 1/2 vacuum hose but it will not fit my intex pool even those the hoses are 1 1/2 also. I have read the threads trying to find answers about possible adapters, but now I am more confused than ever. my pool is ultra frame 26x52 and my filter is the intex sand filter model# sf70110. is there somewhere I can get an adapter and not have to make one because that is out of the question. thanks for your help
