MY PB just laid the pipes for my Jandy Levolor K1100 Autofill, and I am curious about something. I had envisioned that the water bib from the side of my house would be connected to the pool, but this structure is much different. From my house hose bib (see picture), the pipe runs to the pad (see picture). IMG_1637 - Copy.jpg IMG_1638.jpg At the pad it runs straight across where it has a black valve of some sought and then continues where it has a circular grey thing (see picture). It then continues on to the pipe feeding my deep end returns (see picture). IMG_1638.jpgIMG_1641.jpg
The autofill has a pipe inside the pool that looks like a return pipe and that pipe also runs to the pad, where it is sticking straight up out of the groun, but it's not connected to anything.
I suspect the PB did this right, but does anyone understand how this strcuture works?
