I built a clear black tank and tested the Sewer Solution

The nozzle on the Sewer Solution is rather small, so the "high pressure/low volume" is probably accurate. I didn't measure the flow rate though. Without buying more equipment, I could try it using the water meter at the house.

With my insane water pressure, I would have to create a table to down-rate the flow rate for normal situations. It shouldn't be that hard to do, if I can find the right formulas. If I have time this weekend, I'll try it.
