I think i need new return eyeball valves (adjustable ball socket ones for top water movement). I have 3 and the ball socket thing inside can pop out and float away. Not sure if this is by design to swap them out. I also noticed that the closest one to the pump is the strongest. Do they make a replacement that can adjust the flow so the last one (farthest one) can be the strongest to push the debris to the skimmer?
I see they sell the whole assembly do these simply unscrew? how do I know which size to get or are they all the same size.
