Haven't flushed the sediment out of the water heater yet, because tonight I'm in a waterless campground, but I did re-inspect the piping, and I am more and more convinced that we have found the mechanism that distributes this sediment. It's completely obvious how sediment could find its way out of the bottom of the water heater and into the toilet, which is the short pipe that goes through the wall at the right hand side. I think the easiest permanent fix here is going to be to put a shark bite check valve at the far end of the blue loop in the photo.
