| What pump (how many gph) will you be putting over the showers? The recommended would be 10,000-15,000 gph for your setup I think. So I think you might need to just install a 4" tee in that line before the settlement, or if that isn't possible, after it. I doubt even 4- 2" lines will be enough.
How many gph is your current setup running? You may need to pull more for the current setup needs from the skimmers, and use the bottom drains to put what you need over the showers, and any left over through your current setup. That is how I personally would approach it in your situation. |
