The bad: There wasn't a lot of bad to go around. It failed the power failure test only because the return nozzles were put down deep and it siphoned down to where they were. Lesson learned, keep return nozzles up high.
One standpipe, alone, can not keep up with the Dart at full power. I kind of expected that. It does keep up with the amount of flow I plan on using. This was all I really needed.
Also, just for notational purposes, the tank was not 100% level. It sloped left to right, back to front. Garage is intentionally sloped out towards the driveway. It was pretty minor but still there. I have shims to get it perfect once it goes inside the house. It may not need any since the house is only 6 months old but, better to have and not use than to need and not have.
