Hello,
My wife and I started an owner build for a 22'x40' rectangle pool including a 6'x9' raised spa and wet deck. My calculations have the pool and spa around 24,000 gallons and the plumbing run will be 80ft to the equipment pads. The pool has been excavated and we are trying to finalize the plumbing and equipment setup. Will you please help us with feedback/answers to the following questions? Thank you in advance!
We plan to run two 3hp variable speed pumps, two cartridge filters, and two skimmers because we want the pool to be extra clean and lower maintenance. We will also be installing two bubblers in the wet deck and hoping to run 8 spa jets. A plumber told us that he cannot find piping larger than 2.5".

Thank you for your patience and expertise!

- Will a 3hp Pentair variable speed Spa pump be strong enough to run 8 spa jets with 2.5" plumbing and a spa cartridge filter at 80' distance?
- Do we need additional spa returns in addition to the 8 planned spa jets? If so, how many?
- How many drains do we need in the spa?
- Will a 3hp Pentair variable speed Pool pump be strong enough to run 2 skimmers, 2 bubblers, pool main drain, and pool returns with 2.5" plumbing and a cartridge filter at 80' distance?
- How many pool returns should we have?
- In this Jandy two filter diagram could we run the heater for both pumps simultaneously?

Thank you for your patience and expertise!
