Hi everyone! I am starting the process of building my own in ground pool/spa combo and have a question about the spa plumbing. What size plumbing should I use from the pump to the spa suction and returns (jets 12 GPM). The lines to the spa will be approximately 30' The spa will have a 2" loop with 6 jets. I was planning on using 2" for the complete build but wanted to make sure I'm not making a mistake. I will be using 1 Pentair 3hp VS pump for filtration and spa. Any input would be greatly appreciated! Thank you!
