Hi Divin Dave,
Thanks for your reply. Actually I have done so much reading on-line (and on this site in particular) regarding the ins&outs of pool installation & its functioning that I actually understood right away what you were asking. To give you a quick idea of our "future" pool, it will be 20X40 rectangular vinyl inground with 8ft deep end; oversized cartridge filter, intellipro vs pump, heat pump (oversized if possible), swg, solar cover, 2 main drains & 2 skimmers on seperate intake lines (main drains not tied in to skimmers), and 4 seperate returns plus an additional one for an automatic cleaner. So we're now asking for step jets for the two sets we will install (one in deep end, one in shallow end). I want the returns for the step jets to have a union/valve from the pump so we will either run the step jets, or the 4 pool returns; not run both at the same time. Does this make sense? The step jets will only run a few hours per day, mainly to aid in cleaning the steps, and for fun while sitting in those areas.
Thanks, your input is greatly appreciated!
