I am in the process of building a pool in NJ, but haven't picked my PB yet. My pool will be about 1100 -1200 square feet, have a variable speed pump (probably Jandy), a Aqua Comfort AC-150 Heat Pump, a Polaris 280 with 3/4 booster, a Rockwall and Grotto (inside Grotto there will be 6 Jacuzzi jets and blower), 2 Laminar Jets, 2 LED Bubblers in a sunshelf, 2 Ledlights in pool and one in Grotto, Jandy PDA P8 remote control, 90% Quartz finish, Zodiac SWF 185 GMP waterfall pump, Levelor K1100 autofill, and Autopilot Digital SWG. My pool will have 2 skimmers and (as of now) 4 returns. All piping is 2 inch PVC (and I think all returns and skimmers are homeruns), but am considering enlarging piping to 3 inch. I have a lot of questions, but my first one is about safety. The Main pool pump will have 2 main drains (i.e., 2 drains linked to each other at least three feet part) and the other two pumps will each have 2 side suctions (so a total of 4 suctions).
Would making the main pool pump a SVRS reduce the risk of entrapment? Would an SVRS create too many aggravating tripping issues? What about giving the main pump three main drains and each of the other pumps three side suctions? I know two is standard and sufficient for Code, but I have read that having extra drains (i.e., more than 2) reduces the chance of entrapment, since if both got blocked, the third would have enough flow (assuming installed correctly) to prevent entrapment.
Any opinions on how best to increase safety (beyond what Code may require)?
This is my first post, so I apologize if I made any mistakes.
