Pool Water Features
Water features can add a cool water park feel to your pool. You have to check the installation manuals for all equipment to find out the flow requirements.
The sheers require about 12 gpm per linear foot assuming a 3 foot elevation above the water and a 15" projection..
Deck jets don't require very much flow.
Bubblers depend on the specifics.
You need to know the flow rate intended for each pipe. For suction, you want to keep the water velocity below 6 ft/sec. For returns, you want to keep the water velocity below 8 ft/sec.
Size.......6 ft/sec......8 ft/sec 2"..............63...............84 gpm 2.5............90.............119 gpm 3.0".........138.............184 gpm
Each sheer should be plumbed separately on its own line and valve so that you can balance the flow equally.
