When I said I swept the pool, I did mean that I vaccumed the pool. I'm not sure if you mean vacuum to waste when you say vacuum it up. I did not vacuum to waste, but did vacuum.

I do have a bottom drain and have the valve set 50/50 drain/skimmer. I have not ever left the vacuum facing upward in the bottom of the pool.

This morning my pressure guage had gone completely around and was spasming at 0 with a loud hum now. I turned off the filter and put a message on the construction repair forum.

What next??
