Its the 16ft (beige one), 100# sand filter, 1 hp pump(both Hayward) - we had the pump and filter from a previous pool. I guess I don't even need to hard plumb, just get rid of those valves that came with it and make a different fitting to use regular hoses - the silver hoses, which to me are heavier. I would even like to put a skimmer in. I would appreciate any help. Thanks
