Folks I have an in ground pool with pentair equipment. Attempt to explain plumbing. As water leaves sag it first comes to pool return which is open. Valve is at 45 degrees. It then goes to a t with waterfall one way and bubblers the other. My “problem” is the valve is set up to move 90 degrees only. Meaning, I can turn both features full off or both on to varying degrees. End result is waterfall drips bricks instead of flowing out. Any solutions? Only thing that popped in my mind is changing valve for a 180 degree so I can turn one totally off.
