Hi all, after many days sifting through all the threads, I have come to the conclusion to purchase the CircuPool R30 system and install it myself since all 5 bids I got from Pool supply stores range from 1800-2500. I have a 14x28 pool 14,000 gallons. Filter setup, Jacuzzi sand filter (8yrs) and Polaris 380 cleaner. For install, from what I have read, the cell goes on the return to the pool. Here is my issue, it looks like I will need to connect the cell right out of the filter, using a 90 degree elbow to go into the cell. Will this be an issue? I also have a blow out valve on this same line so I will need to keep that intact as well.
