I'm building my inground pool myself and I'm a little confused on the pool return fittings. I ran 2" lines in a loop around the pool. Then dropped down to 1.5" and stubbed them out into the pool. But now I don't know which type of return fitting I need. I ordered some Hayward 1.5" wall fittings but they have threads on the inside and outside. So, I'm assuming these won't work and I need some kind of Insider fitting....maybe with an eyeball?? I see they make some with 1" opening, 3/4" and 1/2". Which ones would be best for the wall returns.
I also have three seperate returns in the floor of a tanning ledge for a fountain/bubbler effect. They will have about 4" of water over them. I don't think I want eyeballs for those do I? Any suggestions.
