Recently moved to a house with a pool and trying to figure everything out.
I have an old Arneson Pool sweep pump in the pump house. The intake and outflow pipes (I think) are cut and I can see some cut pipes cemented in the floor. I assume that the pipes from the pump were, at one time, connected to the pipes in the ground. There is also a little nozzle that protrudes from the side of the pool. I've never used it for anything but as a visual marker to help with the water level (probably not its intended purpose).
Anyhow, what does a pool sweep do? I've looked on this forum and googled, but can't find any picture/video of it in action. Is it worthwhile? If not, is there resale value to the pump?
