I'm in the process of opening a 16 x 32 vinyl pool. On one end it has two skimmers, on the other end it has 2 return jets and approximately 2/3 of the way closest to the skimmers on one side is an auto fill.
I removed the winterization plugs and have 3 return jet caps with different size openings (small, medium and large).
So the question is; Do I use the small return cap on the auto fill and put the cap with the largest opening at the end of the return line ? Not exactly sure which one goes where.
I've done a search and even tried to look it up in my Ultimate Guide to Pool Maintenance book but coming up with no definitive answer.
