Adjustable returnline inlets

[LucyP]

For the first time in 15 years the Pool guy put in these directional return line fixtures at $5.00 each. He said it will increase circulation. But they are not movable for some reason and dont come off. Do you know if they are possibly the wrong side, or way over tightened???
Also they increase the flow alot so its almost a spa effect and some of the water on each of the 2 lines goes along the walls quickly and a touch of rippling above water. Won't this cause more evaporation. He has the shallow end ponted at a left right angle to the end wall and the deep end toward the shallow end.

The ones in my pool are adjustable "eye balls" as well. Mine have a ring with two "nubs" which hold the adjustable "eyes" in place. You have to loosen this to be able to adjust them. When you get them where you want them, you tighten down on the ring. All my returns point down and to the left. This creates a circular motion. I can't visually see the movement, but debris does follow a circular path ultimately ending up in the skimmer.

Sounds like ours. But why is it impossible to both unscrew the whole item or to at least move the eyes???? Am I just too weak or are they probably too small and jammed on by the pool tech ?????

They are probably on too tight...I had to use a large monkey wrench to loosen the outer ring, then the eyeballs are easy to move.

They are overtightened and once you loosen you should use some lube on them so they are easy to move. What you are seeing is not more flow from them, rather a greater pressure drop and less flow but with more force.

[LucyP]

But should I have the pool tech back to do this or is it not too easy to crack with a wrench if I am careful????? I figure if he put them on incorrectly he should get them off, lube them and put them on properly so moving them is easily done whenever it suits us. I would rather not mess with them now unless you think it is a no brainer and they most probably will not break .

Silly question.... why are you trying to remove the eyeballs? If you you have one pointing from deep to shallow and one the oposite way that's right where they should be. That should create a circular motion of the water in the pool.
