I'm remodeling, so here's my chance for a booster pump install. By the looks of things, it looks like the pips are all 2" and gets reduced to 1/5" I have 3 returns going back into the pool. Would it be a good idea to turn one of these returns into a return for the booster pump and cleaner? If so, do I keep the existing size of pipes? Do I buy thicker gauge pvc? Thanks.
