The dye is cast, It's not flowing to the Rubicon

Dye in the tank after  ten minutes
I did a test of the southeast gutter today using florescent dye. I poured two cups of water tracing dye into the gutter, then ran the hose into the same pipe. In about 10 minutes, the dye reached the sump. I happen to have a black light in my house from doing some experiments with simulated night photography. So I used that light to illuminate the sump.  This verified without a doubt that our downspouts are draining to the sump. I think we now know enough about our situation to proceed with repairs and enhancements to better control floods. Despite all this, our area is flood prone, so nothing is guaranteed.
