I have a 22 X 45 Gunite Rectangular Pool in PA. I have already replaced my Hayward TriStar Variables Speed Controller to operate my 3 Phase 3 HP Hayward Variable Speed Pump, and now I need a motor repair. I have 8 returns, 2 skimmers, all with 2.5 Outside diameter plumbing which makes me think it's actual 2 Inches inside. I also have a booster pump for my Hayward Phantom pressure cleaner. There is no automation in this pool. I run it 24 hours a day on low speed and manually turn it to high to super chlorinate with Hayward SWG after high use or when running pool cleaner. I have a 55sf Hayward Cartridge Filter, Ozone System, and SWG My pump is approximately 36 feet from pool's edge and I believe I have approximately 40,000 gallons.

So far most equipment in the pool has failed at least once. So I'm considering changing to newer models of better equipment as my current equipment fails. I'll be replacing Hayward SWG and Hayward LED Lights this season as well.

What size pump do I really need? I have no problem putting in a 2 speed high efficient pump with simplified control unit. And what pumps are recommended?

Thank You
