So bucket sealed. When I reconnected, both unions were leaking, had to really tighten them, then they stopped. Plumbed up the fill pipe with a check valve to hook into the soon to be revised sprinkler system.
Skimmer + Bucket seems to hold water. I filled until all the holes were covered in bucket, and used a vinyl tube to connect the "fill port" to the skimmer for my water test. In an hour there was no measurable loss of water. Before there would have been.
So I filled to the near top of the skimmer and running the bog filtration system. We will see if in the morning the water is still there, or at least has dropped an "acceptable" amount from splash, etc.
If this did not solve it, then it's bog by bog testing.
The flow to the urn is unacceptably low, while the water in the pre-filter bucket is full. There is either a problem in the piping or in the pump.
