I'm cleaning out the pool cabinet and found these parts- Tis is my first year with a pool, so this is all new to me. I suspect a couple of these are automatic cleaners. The white one is made by Hayward, but no part number on it. The clear one does not have any manufacturer one it, and the gray thing says HTH and has a hex shaped hole on the other side (the picture I had of this won't upload). I don't have any use for them now, so I'm just trying to figure out if I can get rid of them or if they have any use to me.
