Have a SS 2 hp pump used for 8 spa jets that is loud and going out. Added Pentair Intelliflow VS pump a couple of years ago whic runs In-floor vacuum cleaner & spa spiller. Have an old Aqua Logic PS4 Rev 2.66. I've read some like to have a separate pump not going thru the filter & some use just the Pentair for both. Since it's already plumbed for 2 pumps is that best or can the valves be set to run just the Pentair? A newbie here. Pool is about 11k gallons. Here is a pic of the setup. Thank you!
