I'm in initial planning stage of my first pool using BYOP. 34x15 rectangle IG, Equipment tbd but probably SWG & heat pump. No spa. I would like a water feature and maybe bubblers on bench. My question is if I only have one pump will the waterfall be the return? So my heated water will return to pool from waterfall? Someone in another thread on this AMAZING forum suggested having in floor returns for heated water. Is it possible to have in floor return AND a water feature with only one pump? A friends pool fountain runs only when the cleaner is on. Would I need a separate pump if I wanted the fountain to run continuosly? Please excuse me if this is an idiot question. I've just begun the process and don't have a grasp of the plumbing required yet. Thanks for any input!
